7. Functional description
7.1 ULPI interface controller
The ISP1505 provides a 12-pin interface that is compliant with UTMI+ Low Pin Interface
(ULPI) Specification Rev. 1.1. This interface must be connected to the USB link.
The ULPI interface controller provides the following functions:
• ULPI-compliant interface and register set
• Allows full control over the USB peripheral, host and SRP functionality
• Parses the USB transmit and receive data
• Prioritizes the USB receive data, USB transmit data, interrupts and register operations
• Low-power mode
• External VBUS source control
• VBUS monitoring, charging and discharging
• 6-pin serial mode and 3-pin serial mode
• Generates RXCMDs; status updates
• Maskable interrupts
For more information on the ULPI protocol, see Section 9.
7.2 USB data serializer and deserializer
The USB data serializer prepares data to transmit on the USB bus. To transmit data, the
USB link sends a transmit command and data on the ULPI bus. The serializer performs
parallel-to-serial conversion, bit stuffing and NRZI encoding. For packets with a PID, the
serializer adds a SYNC pattern to the start of the packet, and an EOP pattern to the end
of the packet. When the serializer is busy and cannot accept any more data, the ULPI
interface controller deasserts NXT.
The USB data deserializer decodes data received from the USB bus. When data is
received, the deserializer strips the SYNC and EOP patterns, and then performs
serial-to-parallel conversion, NRZI decoding and discarding of stuff bits on the data
payload. The ULPI interface controller sends data to the USB link by asserting DIR, and
then asserting NXT whenever a byte is ready. The deserializer also detects various
receive errors, including bit stuff errors, elasticity buffer underrun or overrun, and
byte-alignment errors.
7.3 Hi-Speed USB (USB 2.0) ATX
The Hi-Speed USB ATX block is an analog front-end containing the circuitry needed to
transmit, receive and terminate the USB bus in high-speed, full-speed and low-speed, for
USB peripheral, host and OTG implementations. The following circuitry is included:
• Differential drivers to transmit data at high-speed, full-speed and low-speed
• Differential and single-ended receivers to receive data at high-speed, full-speed and
low-speed
• Squelch circuit to detect high-speed bus activity

NXP Semiconductors
ULPI HS USB host and peripheral transceiver
• High-speed disconnect detector
• 45 Ω high-speed bus terminations on DP and DM for peripheral and host modes
• 1.5 kΩ pull-up resistor on DP for full-speed peripheral mode
• 15 kΩ bus terminations on DP and DM for host and OTG modes
For details on controlling resistor settings, see Table 7.
7.4 Voltage regulator
The ISP1505 contains a built-in voltage regulator that conditions the VCC supply for use
inside the ISP1505. The voltage regulator:
• Supports input supply range of 3.0 V < VCC < 3.6 V
• Supplies internal circuitry with 1.8 V and 3.3 V
Remark: The REG1V8 and REG3V3 pins require external decoupling capacitors. For
details, see Section 16.
7.5 Crystal oscillator and PLL
The ISP1505 has a built-in crystal oscillator and a Phase-Locked Loop (PLL) for clock
generation.
The crystal oscillator takes a sine-wave input from an external crystal on the XTAL1 pin,
and converts it to a square wave clock for internal use. Alternatively, a square wave clock
of the same frequency can also be directly driven into the XTAL1 pin. Using an existing
square wave clock can save the cost of the crystal and also reduce the board size.
The PLL takes the square wave clock from the crystal oscillator, and multiplies or divides it
into various frequencies for internal use.
The PLL produces the following frequencies, irrespective of the clock source:
• 60 MHz clock for the ULPI interface controller
• 1.5 MHz for the low-speed USB data
• 12 MHz for the full-speed USB data
• 480 MHz for the high-speed USB data
• Other internal frequencies for data conversion and data recovery
7.6 VBUS comparators
The ISP1505 provides three comparators, VBUS valid comparator, session valid
comparator and session end comparator, to detect the VBUS voltage level.
7.6.1 VBUS valid comparator
This comparator is used by hosts and A-devices to determine whether the voltage on
VBUS is at a valid level for operation. The ISP1505 minimum threshold for the VBUS valid
comparator is VA_VBUS_VLD. Any voltage on VBUS below VA_VBUS_VLD is considered a fault.
During power-up, it is expected that the comparator output will be ignored.

ISP1505A; ISP1505C
NXP Semiconductors
ULPI HS USB host and peripheral transceiver
While it is possible for the external 5 V supply to use the ISP1505 internal A_VBUS_VLD
comparator, typical 5 V supplies must provide their own power fault indicator that can be
connected as an input to the ISP1505 FAULT pin.
7.6.2 Session valid comparator
The session valid comparator is a TTL-level input that determines when VBUS is high
enough for a session to start. Peripherals, A-devices and B-devices use this comparator to
detect when a session is started. The A-device also uses this comparator to determine
when a session is completed. The session valid threshold of the ISP1505 is VB_SESS_VLD
,
with a hysteresis of Vhys(B_SESS_VLD)
.
7.6.3 Session end comparator
The ISP1505 session end comparator determines when VBUS is below the B-device
session end threshold. The B-device uses this threshold to determine when a session has
ended. The session end threshold of the ISP1505 is VB_SESS_END
.
7.7 SRP charge and discharge resistors
The ISP1505 provides on-chip resistors for short-term charging and discharging of VBUS
These are used by the B-device to request a session, prompting the A-device to restore
the VBUS power. First, the B-device makes sure that VBUS is fully discharged from the
previous session by setting the DISCHRG_VBUS register bit to logic 1 and waiting for
SESS_END to be logic 1. Then the B-device charges VBUS by setting the CHRG_VBUS
register bit to logic 1. The A-device sees that VBUS is charged above the session valid
threshold and starts a session by turning on the VBUS power.
.
7.8 Band gap reference voltage
The band gap circuit provides a stable internal voltage reference to bias the analog
circuitry. The band gap requires an accurate external reference resistor RRREF connected
between the RREF and GND pins. For details, see Section 16.
7.9 Power-on reset
The ISP1505 has an internal power-on reset circuit that resets all internal logic on
power-up. The ULPI interface is also reset at power-up.
Remark: When CLOCK starts toggling after power-up, the USB link must issue a reset
command over the ULPI bus to ensure correct operation of the ISP1505.
7.10 Detailed description of pins
7.10.1 DATA[7:0]
The ISP1505 is a Physical layer (PHY) containing a USB transceiver. DATA[7:0] is a
bidirectional data bus. The USB link must drive DATA[7:0] to LOW when the ULPI bus is
idle. When the link has data to transmit to the PHY, it drives a nonzero value.
Weak pull-down resistors are incorporated into DATA[7:0] pins as part of the interface
protect feature. For details, see Section 9.3.1.
The data bus can be reconfigured to carry various data types, as given in Section 8 and
Section 9.

7.10.2 VCC(I/O)
ULPI HS USB host and peripheral transceiver
The input power pin that sets the I/O voltage level. For details, see Section 12, Section 13
and Section 16. VCC(I/O) provides power to on-chip pads of the following pins:
• CLOCK
• DATA[7:0]
• DIR
• NXT
• RESET_N
• STP
7.10.3 RREF
Resistor reference analog I/O pin. A resistor, RRREF, must be connected between RREF
and GND, as shown in Section 16. This provides an accurate voltage reference that
biases internal analog circuitry. Less accurate resistors cannot be used and will render the
ISP1505 unusable.
7.10.4 DP and DM
The DP (data plus) and DM (data minus) are USB differential data pins. These must be
connected to the D+ and D− pins of the USB receptacle.
7.10.5 VCC
VCC is the main input supply voltage for the ISP1505. Decoupling capacitors are
recommended. For details, see Section 16.
7.10.6 VBUS/FAULT
This pin provides two options for VBUS driving and monitoring. If neither function is used,
this pin must be connected to ground.
7.10.6.1 VBUS
By default, this pin acts as an input to VBUS comparators, and also charges and
discharges VBUS for SRP.
The VBUS pin requires a capacitive load as shown in Section 16.
To prevent electrical overstress, it is strongly recommended that you attach a series
resistor on the VBUS pin (RVBUS). RVBUS must not be attached when using the ISP1505
internal charge pump. For details, see Section 16.
7.10.6.2 FAULT (external overcurrent or fault detector)
If an external VBUS overcurrent or fault circuit is used, the output fault indicator of that
circuit can be connected to the ISP1505 FAULT input pin. The ISP1505 will inform the link
of VBUS fault events by sending RXCMDs on the ULPI bus. To use the FAULT pin, the link
must:
• Set the USE_EXT_VBUS_IND register bit to logic 1.
• Set the polarity of the external fault signal using the IND_COMPL register bit.
• Set the IND_PASSTHRU register bit to logic 1.

7.10.7 REG3V3 and REG1V8
Regulator output voltage. These supplies are used to power the ISP1505 internal digital
and analog circuits, and must not be used to power external circuits.
For correct operation of the regulator, it is recommended that you connect REG3V3 and
REG1V8 to decoupling capacitors. For an example, see Section 16.
7.10.8 XTAL1 and XTAL2
XTAL1 is the crystal input, and XTAL2 is the crystal output. The allowed frequency on the
XTAL1 pin depends on the ISP1505 product version.
If the link requires a 60 MHz clock from the ISP1505, then either a crystal must be
attached, or a clock of the same frequency must be driven into XTAL1, with XTAL2 left
floating.
If a crystal is attached, it requires external load capacitors to GND on each terminal of the
crystal. For details, see Section 16.
If at any time the system wants to stop the clock on XTAL1, the link must first put the
ISP1505 into low-power mode. The clock on XTAL1 must be restarted before low-power
mode is exited.
7.10.9 RESET_N/PSW_N
This pin provides two optional functions. If neither function is used, this pin must be
connected to VCC(I/O)
.
7.10.9.1 RESET_N
An active LOW asynchronous reset pin that resets all circuits in the ISP1505. The
ISP1505 contains an internal power-on reset circuit, and therefore using the RESET_N
pin is optional. If RESET_N is not used, it must be connected to VCC(I/O)
.
For details on using RESET_N, see Section 9.3.2.
7.10.9.2 PSW_N
PSW_N is an active LOW, open-drain output pin. This pin can be connected to an active
LOW, external VBUS switch or charge pump enable circuit to control the external VBUS
power source. An external pull-up resistor, Rpullup, is required when PSW_N is used. This
pin is open-drain, allowing ganged-mode power control for multiple USB ports. For
application details, see Section 16.
To use the PSW_N pin, the link must disable the reset input by setting the
IGNORE_RESET bit in the Power Control register to logic 1. This will ensure that PSW_N
is not misinterpreted as a reset.
If the link is in host mode, it can enable the external VBUS power source by setting the
DRV_VBUS_EXT bit in the OTG Control register to logic 1. The ISP1505 will drive
PSW_N to LOW to enable the external VBUS power source. If the link detects an
overcurrent condition (the VBUS state in RXCMD is not 11b), it must disable the external
VBUS supply by setting DRV_VBUS_EXT to logic 0.

NXP Semiconductors
7.10.10 DIR
ULPI HS USB host and peripheral transceiver
ULPI direction output pin. Controls the direction of the data bus. By default, the ISP1505
holds DIR at LOW, causing the data bus to be an input. When DIR is LOW, the ISP1505
listens for data from the link. The ISP1505 pulls DIR to HIGH only when it has data to
send to the link, which is for one of two reasons:
• To send the USB receive data, RXCMD status updates and register reads data to the
link.
• To block the link from driving the data bus during power-up, reset and low-power
mode (suspend).
For details on DIR usage, refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
7.10.11 STP
ULPI stop input pin. The link must assert STP to signal the end of a USB transmit packet
or a register write operation. When DIR is asserted, the link can optionally assert STP to
abort the ISP1505, causing it to deassert DIR in the next clock cycle. A weak pull-up
resistor is incorporated into the STP pin as part of the interface protect feature. For details,
see Section 9.3.1.
For details on STP usage, refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
7.10.12 NXT
ULPI next data output pin. The ISP1505 holds NXT at LOW, by default. When DIR is LOW
and the link is sending data to the ISP1505, NXT will be asserted to notify the link to
provide the next data byte. When DIR is at HIGH and the ISP1505 is sending data to the
link, NXT will be asserted to notify the link that another valid byte is on the bus. NXT is not
used for the register read data or the RXCMD status update.
For details on NXT usage, refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
7.10.13 CLOCK
A 60 MHz interface clock to synchronize the ULPI bus. The ISP1505 provides two
clocking options:
• A crystal is attached between the XTAL1 and XTAL2 pins.
• A clock is driven into the XTAL1 pin, with the XTAL2 pin left floating.
For details on CLOCK usage, refer to UTMI+ Low Pin Interface (ULPI) Specification
Rev. 1.1.
7.10.14 GND (die pad)
Global ground signal. The die pad is exposed on the underside of the package as a
ground plate. This acts as a ground to all circuits in the ISP1505. To ensure correct
operation of the ISP1505, GND must be soldered to the cleanest ground available.

8. Modes of operation
8.1 ULPI modes
The ISP1505 ULPI bus can be programmed to operate in four modes. Each mode
reconfigures the signals on the data bus as described in the following subsections. Setting
more than one mode will lead to undefined behavior.
8.1.1 Synchronous mode
This is default mode. At power-up, and when CLOCK is stable, the ISP1505 will enter
synchronous mode. The link must synchronize all ULPI signals to CLOCK, meeting the
set-up and hold times as defined in Section 15. A description of the ULPI pin behavior in
synchronous mode is given in Table 3.
This mode is used by the link to perform the following tasks:
• High-speed detection handshake (chirp)
• Transmit and receive USB packets
• Read and write to registers
• Receive USB status updates (RXCMDs)
For more information on various synchronous mode protocols, see Section 9.

CLOCK
O
60 MHz interface clock. If a crystal is attached or a clock is driven into
the XTAL1 pin, the ISP1505 will drive a 60 MHz output clock.
DATA[7:0] I/O
8-bit data bus. In synchronous mode, the link drives DATA[7:0] to LOW
by default. The link initiates transfers by sending a nonzero data pattern
called TXCMD (transmit command). In synchronous mode, the direction
of DATA[7:0] is controlled by DIR. Contents of DATA[7:0] lines must be
ignored for exactly one clock cycle whenever DIR changes value. This is
called the turnaround cycle.
Data lines have fixed direction and different meaning in low-power and
serial modes.

ISP1505
DIR
O
Direction: Controls the direction of data bus DATA[7:0]. In synchronous
mode, the ISP1505 drives DIR to LOW by default, making the data bus
an input so that the ISP1505 can listen for TXCMDs from the link. The
ISP1505 drives DIR to HIGH only when it has data for the link. When
DIR and NXT are HIGH, the byte on the data bus contains decoded
USB data. When DIR is HIGH and NXT is LOW, the byte contains
status information called RXCMD (receive command). The only
exception to this rule is when the PHY returns register read data, where
NXT is also LOW, replacing the usual RXCMD byte. Every change in
DIR causes a turnaround cycle on the data bus, during which DATA[7:0]
is not valid and must be ignored by the link.
DIR is always asserted during low-power and serial modes.
STP
NXT
I
Stop: In synchronous mode, the link drives STP to HIGH for one cycle
after the last byte of data is sent to the ISP1505. The link can optionally
assert STP to force DIR to be deasserted.
In low-power and serial modes, the link holds STP at HIGH to wake up
the ISP1505, causing the ULPI bus to return to synchronous mode.
O
Next: In synchronous mode, the ISP1505 drives NXT to HIGH to
throttle data. If DIR is LOW, the ISP1505 asserts NXT to notify the link
to place the next data byte on DATA[7:0] in the following clock cycle. If
DIR is HIGH, the ISP1505 asserts NXT to notify the link that a valid
USB data byte is on DATA[7:0] in the current cycle. The ISP1505 always
drives an RXCMD when DIR is HIGH and NXT is LOW, unless register
read data is to be returned to the link in the current cycle.
NXT is not used in low-power or serial mode.
8.1.2 Low-power mode
When the USB is idle, the link can place the ISP1505 into low-power mode (also called
suspend mode). In low-power mode, the data bus definition changes to that shown in
Table 4. To enter low-power mode, the link sets the SUSPENDM bit in the Function
Control register to logic 0. To exit low-power mode, the link asserts the STP signal. The
ISP1505 will draw only suspend current from the VCC supply (see Table 44).
During low-power mode, the clock on XTAL1 may be stopped. The clock must be started
again before asserting STP to exit low-power mode. After exiting low-power mode, the
ISP1505 will send an RXCMD to the link if a change was detected in any interrupt source,
and the change still exists. An RXCMD may not be sent if the interrupt condition is
removed before exiting.
For more information on low-power mode enter and exit protocols, refer to UTMI+ Low Pin
Interface (ULPI) Specification Rev. 1.1.

8.1.3 6-pin full-speed or low-speed serial mode
If the link requires a 6-pin serial interface to transmit and receive full-speed or low-speed
USB data, it can set the ISP1505 to 6-pin serial mode. In 6-pin serial mode, the DATA[7:0]
bus definition changes to that shown in Table 5. To enter 6-pin serial mode, the link sets
the 6PIN_FSLS_SERIAL bit in the Interface Control register to logic 1. To exit 6-pin serial
mode, the link asserts STP. This is provided primarily for links that contain legacy
full-speed or low-speed functionality, providing a more cost-effective upgrade path to
high-speed. An interrupt pin is also provided to inform the link of USB events. If the link
requires CLOCK to be running during 6-pin serial mode, the CLOCK_SUSPENDM
register bit must be set to logic 1.
For more information on 6-pin serial mode enter and exit protocols, refer to UTMI+ Low

If the link requires a 3-pin serial interface to transmit and receive full-speed or low-speed
USB data, it can set the ISP1505 to 3-pin serial mode. In 3-pin serial mode, the data bus
definition changes to that shown in Table 6. To enter 3-pin serial mode, the link sets the
3PIN_FSLS_SERIAL bit in the Interface Control register to logic 1. To exit 3-pin serial
mode, the link asserts STP. This is primarily provided for links that contain legacy
full-speed or low-speed functionality, providing a more cost-effective upgrade path to

8.2 USB and OTG state transitions
A Hi-Speed USB peripheral, host or OTG device handles more than one electrical state as
defined in Universal Serial Bus Specification Rev. 2.0 and On-The-Go Supplement to the
USB 2.0 Specification Rev. 1.3. The ISP1505 accommodates the various states through
register bit settings of XCVRSELECT[1:0], TERMSELECT, OPMODE[1:0],
DP_PULLDOWN and DM_PULLDOWN.
Table 7 summarizes operating states. The values of register settings in Table 7 will force
resistor settings as also given in Table 7. Resistor setting signals are defined as follows:
• RPU_DP_EN enables the 1.5 kΩ pull-up resistor on DP
• RPD_DP_EN enables the 15 kΩ pull-down resistor on DP
• RPD_DM_EN enables the 15 kΩ pull-down resistor on DM
• HSTERM_EN enables the 45 Ω termination resistors on DP and DM
It is up to the link to set the desired register settings.

9. Protocol description
The following subsections describe the protocol for using the ISP1505.
9.1 ULPI references
The ISP1505 provides a 12-pin ULPI interface to communicate with the link. It is highly
recommended that you read UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1 and
UTMI+ Specification Rev. 1.0.
9.2 Power-On Reset (POR)
An internal POR is generated when REG1V8 rises above VPOR(trip), for at least
tw(REG1V8_H). The internal POR pulse will also be generated whenever REG1V8 drops
below VPOR(trip) for more than tw(REG1V8_L), and then rises above VPOR(trip) again. The
voltage on REG1V8 is generated from VCC
.
To give a better view of the functionality, Figure 3 shows a possible curve of REG1V8. The
internal POR starts with logic 0 at t0. At t1, the detector will see the passing of the trip
level so that POR turns to logic 1 and a delay element will add another tPORP before it
drops to logic 0. If REG1V8 dips from t2 to t3 for > tw(REG1V8_L), another POR pulse is
generated. If the dip at t4 to t5 is too short, that is, < tw(REG1V8_L), the internal POR pulse
will not react and will remain LOW.

Fig 3. Internal power-on reset timing
9.3 Power-up, reset and bus idle sequence
Figure 4 shows a typical start-up sequence.
On power-up, the ISP1505 performs an internal power-on reset and asserts DIR to
indicate to the link that the ULPI bus cannot be used. When the internal PLL is stable, the
ISP1505 deasserts DIR. The power-up time depends on the VCC supply rise time, the
crystal start-up time, and PLL start-up time tstartup(o)(CLOCK). Whenever DIR is asserted,
the ISP1505 drives the NXT pin to LOW and drives DATA[7:0] with RXCMD values. When
DIR is deasserted, the link must drive the data bus to a valid level. By default, the link
must drive data to LOW. When the ISP1505 initially deasserts DIR on power-up, the link
must ignore all RXCMDs until it resets the ISP1505. Before beginning USB packets, the
link must set the RESET bit in the Function Control register to reset the ISP1505. After the
RESET bit is set, the ISP1505 will assert DIR until the internal reset completes. The
ISP1505 will automatically deassert DIR and clear the RESET bit when reset has
completed. After every reset, an RXCMD is sent to the link to update USB status
information. After this sequence, the ULPI bus is ready for use and the link can start USB
operations.

ULPI HS USB host and peripheral transceiver
If a crystal is attached or a clock is driven into the XTAL1 pin, the ISP1505 will drive a
60 MHz clock out from the CLOCK pin when DIR deasserts. This is shown as CLOCK in
Figure 4.
The recommended power-up sequence for the link is as follows:
1. The link waits for 1 ms, ignoring all the ULPI pin status.
2. The link may start to detect DIR status level. If DIR is detected as LOW for three clock
cycles, the link may send a RESET command.
The ULPI interface is ready for use.

t1 = VCC and VCC(I/O) are applied to the ISP1505. The ISP1505 regulator starts to turn on.
t2 = ULPI pads detect REG1V8 rising above the REG1V8 regulator threshold and are not in 3-state. These pads may drive
either LOW or HIGH. It is recommended that the link ignores the ULPI pins status during tPWRUP
.
t3 = The POR threshold is reached and a POR pulse is generated. After the POR pulse, ULPI pins are driven to a defined level.
DIR is driven to HIGH and the other pins are driven to LOW.
t4 = The internal PLL is stabilized after tstartup(PLL). If the 19.2 MHz or 26 MHz clock is started before POR, the internal PLL will
be stabilized after tstartup(PLL) from POR. The CLOCK pin starts to output 60 MHz. The DIR pin will transition from HIGH to LOW.
The DIR pin will remain LOW before the link issues a RESET command to the ISP1505.
t5 = The power-up sequence is completed and the ULPI bus interface is ready for use.
Fig 4. Power-up and reset sequence required before the ULPI bus is ready for use
9.3.1 Interface protection
By default, the ISP1505 enables a weak pull-up resistor on STP. If the STP pin is
unexpectedly HIGH at any time, the ISP1505 will protect the ULPI interface by enabling
weak pull-down resistors on DATA[7:0].
The interface protect feature prevents unwanted activity of the ISP1505 whenever the
ULPI interface is not correctly driven by the link. For example, when the link powers up
more slowly than the ISP1505.

The interface protect feature can be disabled by setting the INTF_PROT_DIS bit to logic 1.
9.3.2 Interface behavior with respect to RESET_N
The use of the RESET_N pin is optional. When RESET_N is asserted (LOW), the
ISP1505 will assert DIR. All logic in the ISP1505 will be reset, including the analog
circuitry and ULPI registers. During reset, the link must drive DATA[7:0] and STP to LOW;
otherwise undefined behavior may result. When RESET_N is deasserted (HIGH), the DIR
output will deassert (LOW) four or five clock cycles later. Figure 5 shows the ULPI
interface behavior when RESET_N is asserted (LOW), and subsequently deasserted
(HIGH). If RESET_N is not used, it must be connected to VCC(I/O)
.

9.4 VBUS power and fault detection
9.4.1 Driving 5 V on VBUS
The ISP1505 supports external 5 V supplies. The ISP1505 can control the external supply
using the active-LOW PSW_N open-drain output pin. To enable the external supply by
driving PSW_N to LOW, the link must set the DRV_VBUS_EXT bit in the OTG Control
register to logic 1. When the DRV_VBUS_EXT bit is set, the DRV_VBUS bit can be set to
any value and will be ignored.
9.4.2 Fault detection
The ISP1505 supports external VBUS fault detector circuits. An overcurrent detection
circuit is required for host applications that supply more than 100 mA on VBUS for voltages
between 4.75 V to 5.25 V. For low-power applications supplying less than 100 mA, the
VBUS power line can directly be connected to the VBUS/FAULT pin on the ISP1505 and the
link can utilize the internal A_VBUS_VLD comparator.
The ISP1505 supports external VBUS fault detector circuits that output a digital fault
indicator signal. The indicator signal must be connected to the VBUS/FAULT pin. To enable
the ISP1505 to monitor the digital fault input, the link must set the USE_EXT_VBUS_IND
bit in the OTG Control register and the IND_PASSTHRU bit in the Interface Control
register to logic 1. For details, see Figure 7.

The FAULT input pin is mapped to the A_VBUS_VLD bit in RXCMD. Any changes for the
FAULT input will trigger RXCMD carrying the FAULT condition with A_VBUS_VLD.
9.5 TXCMD and RXCMD
Commands between the ISP1505 and the link are described in the following subsections.
9.5.1 TXCMD
By default, the link must drive the ULPI bus to its idle state of 00h. To send commands and
USB packets, the link drives a nonzero value on DATA[7:0] to the ISP1505 by sending a
byte called TXCMD. Commands include USB packet transmissions, and register reads
and writes. Once the TXCMD is interpreted and accepted by the ISP1505, the NXT signal
is asserted and the link can follow up with the required number of data bytes. The TXCMD
byte format is given in Table 8. Any values other than those in Table 8 are illegal and may
result in undefined behavior.
Various TXCMD packet and register sequences are shown in later sections.

an RXCMD byte on the data bus. The RXCMD data byte format is given in Table 9.
The ISP1505 will automatically send an RXCMD whenever there is a change in any of the
RXCMD data fields. The link must be able to accept an RXCMD at any time; including
single RXCMDs, back-to-back RXCMDs, and RXCMDs at any time during USB receive
packets when NXT is LOW. An example is shown in Figure 6. For details and diagrams,
refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.
An RXCMD may not be sent when exiting low-power mode or serial mode, if the interrupt
condition is removed before exiting.

By default, this signal is not used and is not needed in typical designs. Optionally, the link can
enable the BVALID_RISE and/or BVALID_FALL bits in the Power Control register. Corresponding

9.5.2.1 Linestate encoding
LINESTATE[1:0] reflects the current state of DP and DM. Whenever the ISP1505 detects
a change in DP or DM, an RXCMD will be sent to the link with the new LINESTATE[1:0]
value. The value given on LINESTATE[1:0] depends on the setting of various registers.
Table 10 shows the LINESTATE[1:0] encoding for upstream facing ports, which applies to
peripherals. Table 11 shows the LINESTATE[1:0] encoding for downstream facing ports,
which applies to host controllers. Dual-role devices must choose the correct table,
depending on whether it is in peripheral or host mode.

9.5.2.2 VBUS state encoding
USB devices must monitor the VBUS voltage for purposes such as overcurrent detection,
starting a session and SRP. The VBUS state field in the RXCMD is an encoding of the
voltage level on VBUS
.
The A_VBUS_VLD, SESS_VLD and SESS_END indicators in the VBUS state are directly
taken from internal comparators built-in to the ISP1505, and encoded as shown in Table 9
and Table 12.
An RXCMD may not be sent when exiting low-power mode or serial mode, if the interrupt
condition is removed before exiting.

Note that VBUS and FAULT share the same pin and cannot be simultaneously used.

A description on how to use and select the VBUS state encoding is given in
Section 9.5.2.3.

9.5.2.3 Using and selecting the VBUS state encoding
The VBUS state encoding is shown in Table 9. The ISP1505 will send an RXCMD to the
link whenever there is a change in the VBUS state. To receive VBUS state updates, the link
must first enable the corresponding interrupts in the USB Interrupt Enable Rising Edge
and USB Interrupt Enable Falling Edge registers.
The link can use the VBUS state to monitor VBUS and take appropriate action. Table 13
shows the recommended usage for typical applications.

Standard USB host controllers: For standard hosts, the system must be able to provide
500 mA on VBUS in the range of 4.75 V to 5.25 V. An external circuit must be used to
detect overcurrent conditions. If the external overcurrent detector provides a digital fault
signal, then the fault signal must be connected to the ISP1505 FAULT input pin, and the
link must do the following:
1. Set the IND_COMPL bit in the Interface Control register to logic 0 or logic 1,
depending on the polarity of the external fault signal.
2. Set the IND_PASSTHRU bit in the Interface Control register to logic 1.
3. Set the USE_EXT_VBUS_IND bit in the OTG Control register to logic 1.
Standard USB peripheral controllers: Standard peripherals must be able to detect
when VBUS is at a sufficient level for operation. SESS_VLD must be enabled to detect the
start and end of USB peripheral operations. Detection of A_VBUS_VLD and SESS_END
thresholds is not needed for standard peripherals.

OTG devices: The ISP1505 provides partial OTG support. A low-power OTG A-device
that supplies less than 100 mA on VBUS can connect the VBUS power to the ISP1505 VBUS
pin. The internal A_VBUS_VLD comparator can be used. If the OTG A-device provides
more than 100 mA on VBUS, an overcurrent detector must be used and Section “Standard
USB host controllers” on page 25 applies. The OTG A-device also uses SESS_VLD to
detect when an OTG B-device is initiating VBUS pulsing SRP.
When an OTG device is configured as an OTG B-device, SESS_VLD must be used to
detect when VBUS is at a sufficient level for operation. SESS_END must be used to detect
when VBUS has dropped to a LOW level, allowing the B-device to safely initiate VBUS
pulsing SRP.
9.5.2.4 RxEvent encoding
The RxEvent field (see Table 14) of the RXCMD informs the link of information related
packets received on the USB bus. RxActive and RxError are defined in USB 2.0
Transceiver Macrocell Interface (UTMI) Specification Ver. 1.05. HostDisconnect is defined
in UTMI+ Specification Rev. 1.0. A short definition is also given in the following
subsections.

RxActive: When the ISP1505 has detected a SYNC pattern on the USB bus, it signals an
RxActive event to the link. An RxActive event can be communicated using two methods.
The first method is for the ISP1505 to simultaneously assert DIR and NXT. The second
method is for the ISP1505 to send an RXCMD to the link with the RxActive field in
RxEvent bits set to logic 1. The link must be able to detect both methods. RxActive frames
the receive packet from the first byte to the last byte.
The link must assume that RxActive is set to logic 0 when indicated in an RXCMD or when
DIR is deasserted, whichever occurs first.
The link uses RxActive to time high-speed packets and ensure that bus turnaround times
are met. For more information on the USB packet timing, see Section 9.8.1.
RxError: When the ISP1505 has detected an error while receiving a USB packet, it
deasserts NXT and sends an RXCMD with the RxError field set to logic 1. The received
packet is no longer valid and must be dropped by the link.
HostDisconnect: HostDisconnect is encoded into the RxEvent field of the RXCMD.
HostDisconnect is valid only when the ISP1505 is configured as a host (both
DP_PULLDOWN and DM_PULLDOWN are set to logic 1), and indicates to the host
controller when a peripheral is connected or disconnected. The host controller must
enable HostDisconnect by setting the HOST_DISCON_R and HOST_DISCON_F bits in
the USB Interrupt Enable Rising Edge and USB Interrupt Enable Falling Edge registers,
respectively. Changes in HostDisconnect will cause the PHY to send an RXCMD to the
link with the updated value.

Figure 8 shows register read and write sequences. The ISP1505 supports immediate
addressing and extended addressing register operations. Extended register addressing is
optional for links. Note that register operations will be aborted if the ISP1505 unexpectedly
asserts DIR during the operation. When a register operation is aborted, the link must retry
until successful. For more information on register operations, refer to UTMI+ Low Pin

9.7 USB reset and high-speed detection handshake (chirp)
Figure 9 shows the sequence of events for USB reset and high-speed detection
handshake (chirp). The sequence is shown for hosts and peripherals. Figure 9 does not
show all RXCMD updates and timing is not to scale. The sequence is as follows:
1. USB reset: The host detects a peripheral attachment as low-speed if DM is HIGH and
as full-speed if DP is HIGH. If a host detects a low-speed peripheral, it does not follow
the remainder of this protocol. If a host detects a full-speed peripheral, it resets the
peripheral by writing to the Function Control register and setting
XCVRSELECT[1:0] = 00b (high-speed) and TERMSELECT = 0b, which drives SE0
on the bus (DP and DM connected to ground through 45 Ω). The host also sets
OPMODE[1:0] = 10b for correct chirp transmit and receive. The start of SE0 is labeled
T0.
Remark: To receive chirp signaling, the host must also consider the high-speed
differential receiver output. The host controller must interpret LINESTATE[1:0] as
shown in Table 11.
2. High-speed detection handshake (chirp)
a. Peripheral chirp: After detecting SE0 for no less than 2.5 µs, if the peripheral is
capable of high-speed, it sets XCVRSELECT[1:0] = 00b (high-speed) and
OPMODE[1:0] = 10b (chirp). The peripheral immediately follows this with a
TXCMD (NOPID), transmitting a Chirp K for no less than 1 ms and ending no more

than 7 ms after reset time T0. If the peripheral is in low-power mode, it must wake
up its clock within 5.6 ms, leaving 200 µs for the link to start transmitting the
Chirp K, and 1.2 ms for the Chirp K to complete (worst case with 10 % slow clock).
b. Host chirp: If the host does not detect the peripheral chirp, it must continue
asserting SE0 until the end of reset. If the host detects the peripheral Chirp K for
no less than 2.5 µs, then no more than 100 µs after the bus leaves the Chirp K
state, the host sends a TXCMD (NOPID) with an alternating sequence of Chirp Ks
and Js. Each Chirp K or Chirp J must last for no less than 40 µs and no longer than
60 µs.
c. High-speed idle: The peripheral must detect a minimum of Chirp K-J-K-J-K-J. Each
Chirp K and Chirp J must be detected for at least 2.5 µs. After seeing that
minimum sequence, the peripheral sets TERMSELECT = 0b and
OPMODE[1:0] = 00b. The peripheral is now in high-speed mode and sees !squelch
(01b on LINESTATE). When the peripheral sees squelch (10b on LINESTATE), it
knows that the host has completed chirp and waits for Hi-Speed USB traffic to
begin. After transmitting the chirp sequence, the host changes OPMODE[1:0] to
00b and begins sending USB packets.
For more information, refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1.

9.9 Preamble
Preamble packets are headers to low-speed packets that must travel over a full-speed
bus, between a host and a hub. To enter preamble mode, the link sets
XCVRSELECT[1:0] = 11b in the Function Control register. When in preamble mode, the
ISP1505 operates just as in full-speed mode, and sends all data with the full-speed rise
time and fall time. Whenever the link transmits a USB packet in preamble mode, the
ISP1505 will automatically send a preamble header at full-speed bit rate before sending
the link packet at low-speed bit rate. The ISP1505 will ensure a minimum gap of four
full-speed bit times between the last bit of the full-speed PRE PID and the first bit of the
low-speed packet SYNC. The ISP1505 will drive a J for at least one full-speed bit time
after sending the PRE PID, after which the pull-up resistor can hold the J state on the bus.
An example transmit packet is shown in Figure 13.
In preamble mode, the ISP1505 can also receive low-speed packets from the full-speed
bus.

Fig 13. Preamble sequence
9.10 USB suspend and resume
9.10.1 Full-speed and low-speed host-initiated suspend and resume
Figure 14 illustrates how a host or a hub places a full-speed or low-speed peripheral into
suspend and sometime later initiates resume signaling to wake up the downstream
peripheral. Note that Figure 14 timing is not to scale, and does not show all RXCMD
LINESTATE updates.
The sequence of events for a host and a peripheral, both with ISP1505, is as follows:
1. Idle: Initially, the host and the peripheral are idle. The host has its 15 kΩ pull-down
resistors enabled (DP_PULLDOWN and DM_PULLDOWN are set to 1b) and 45 Ω
terminations disabled (TERMSELECT is set to 1b). The peripheral has the 1.5 kΩ
pull-up resistor connected to DP for full-speed or DM for low-speed (TERMSELECT is
set to 1b).
2. Suspend: When the peripheral sees no bus activity for 3 ms, it enters the suspend
state. The peripheral link places the PHY into low-power mode by clearing the
SUSPENDM bit in the Function Control register, causing the PHY to draw only
suspend current. The host may or may not be powered down.
3. Resume K: When the host wants to wake up the peripheral, it sets OPMODE[1:0] to
10b and transmits a K for at least 20 ms. The peripheral link sees the resume K on
LINESTATE, and asserts STP to wake up the PHY.
4. EOP: When STP is asserted, the ISP1505 on the host side automatically appends an
EOP of two bits of SE0 at low-speed bit rate, followed by one bit of J. The ISP1505 on
the host side knows to add the EOP because DP_PULLDOWN and DM_PULLDOWN
are set to 1b for a host. After the EOP is completed, the host link sets OPMODE[1:0]
to 00b for normal operation. The peripheral link sees the EOP and also resumes
normal operation.

NXP Semiconductors
ULPI HS USB host and peripheral transceiver
The sequence of events related to a host and a peripheral, both with ISP1505, is as
follows:
1. High-speed idle: Initially, the host and the peripheral are idle. The host has its 15 kΩ
pull-down resistors enabled (DP_PULLDOWN and DM_PULLDOWN are set to 1b)
and 45 Ω terminations enabled (TERMSELECT is set to 0b). The peripheral has its
45 Ω terminations enabled (TERMSELECT is set to 0b).
2. Full-speed suspend: When the peripheral sees no bus activity for 3 ms, it enters the
suspend state. The peripheral link places the ISP1505 into full-speed mode
(XCVRSELECT is set to 01b), removes 45 Ω terminations, and enables the 1.5 kΩ
pull-up resistor on DP (TERMSELECT is set to 1b). The peripheral link then places
the ISP1505 into low-power mode by clearing SUSPENDM, causing the ISP1505 to
draw only suspend current. The host also changes the ISP1505 to full-speed
(XCVRSELECT is set to 01b), removes 45 Ω terminations (TERMSELECT is set to
1b), and then may or may not be powered down.
3. Resume K: When the host wants to wake up the peripheral, it sets OPMODE to 10b
and transmits a full-speed K for at least 20 ms. The peripheral link sees the resume K
(10b) on LINESTATE, and asserts STP to wake up the ISP1505.
4. High-speed traffic: The host link sets high-speed (XCVRSELECT is set to 00b) and
enables its 45 Ω terminations (TERMSELECT is set to 0b). The peripheral link sees
SE0 on LINESTATE and also sets high-speed (XCVRSELECT is set to 00b), and
enables its 45 Ω terminations (TERMSELECT is set to 0b). The host link sets
OPMODE to 00b for normal high-speed operation.

9.10.3 Remote wake-up
The ISP1505 supports peripherals that initiate remote wake-up resume. When placed into
USB suspend, the peripheral link remembers at what speed it was originally operating.
Depending on the original speed, the link follows one of the protocols detailed here. In
Figure 16, timing is not to scale, and not all RXCMD LINESTATE updates are shown.
The sequence of events related to a host and a peripheral, both with ISP1505, is as
follows:
1. Both the host and the peripheral are assumed to be in low-power mode.
2. The peripheral begins remote wake-up by re-enabling its clock and setting its
SUSPENDM bit to 1b.
3. The peripheral begins driving K on the bus to signal resume. Note that the peripheral
link must assume that LINESTATE is K (01b) while transmitting because it will not
receive any RXCMDs.
4. The host recognizes the resume, re-enables its clock and sets its SUSPENDM bit.
5. The host takes over resume driving within 1 ms of detecting the remote wake-up.
6. The peripheral stops driving resume.
7. The peripheral sees the host continuing to drive resume.
8. The host stops driving resume and the ISP1505 automatically adds the EOP to the
end of resume. The peripheral recognizes the EOP as the end of resume.
9. Both the host and the peripheral revert to normal operation by writing 00b to
OPMODE. If the host or the peripheral was previously in high-speed mode, it must
revert to high-speed before the SE0 of the EOP is completed. This can be achieved
by writing XCVRSELECT[1:0] = 00b and TERMSELECT = 0b after LINESTATE
indicates SE0.

9.11 No automatic SYNC and EOP generation (optional)
This setting allows the link to turn off the automatic SYNC and EOP generation, and must
be used for high-speed packets only. It is provided for backward compatibility with legacy
controllers that include SYNC and EOP bytes in the data payload when transmitting
packets. The ISP1505 will not automatically generate the SYNC and EOP patterns when
OPMODE[1:0] is set to 11b. The ISP1505 will still NRZI encode data and perform bit
stuffing. An example of a sequence is shown in Figure 17. The link must always send
packets using the TXCMD (NOPID) type. The ISP1505 does not provide a mechanism to
control bit stuffing in individual bytes, but will automatically turn off bit stuffing for EOP
when STP is asserted with data set to FEh. If data is set to 00h when STP is asserted, the

9.12 On-The-Go operations
On-The-Go (OTG) is a supplement to Universal Serial Bus Specification Rev. 2.0 that
allows a portable USB device to assume the role of a limited USB host by defining
improvements, such as a small connector and low power. Non-portable devices, such as
standard hosts and embedded hosts, can also benefit from OTG features.
The ISP1505 OTG PHY is designed to support all the tasks specified in the OTG
supplement. The ISP1505 provides the front-end analog support for Host Negotiation
Protocol (HNP) and Session Request Protocol (SRP) for dual-role devices. The
supporting components include:
• Voltage comparators
– A_VBUS_VLD
– SESS_VLD (session valid, can be used for both A-session and B-session valid)
– SESS_END (session end)
• Pull-up and pull-down resistors on DP and DM
• Charge and discharge resistors on VBUS
For complete OTG support, the system designer must add a VBUS power supply and
detect the value on the ID pin of the USB cable. This is not provided on the ISP1505.
The following subsections describe how to use the ISP1505 OTG components.

9.12.1 OTG comparators
The ISP1505 provides comparators that conform to On-The-Go Supplement to the
USB 2.0 Specification Rev. 1.3 requirements of VA_VBUS_VLD, VA_SESS_VLD, VB_SESS_VLD
and VB_SESS_END. In this data sheet, VA_SESS_VLD and VB_SESS_VLD are combined into
VB_SESS_VLD. Comparators are described in Section 7.6. Changes in comparator values
are communicated to the link by RXCMDs as described in Section 9.5.2.2. Control over
comparators is described in Section 10.1.5 to Section 10.1.8.
9.12.2 Pull-up and pull-down resistors
The USB resistors on DP and DM can be used to initiate data-line pulsing SRP. The link
must set the required bus state using mode settings given in Table 7.
9.12.3 VBUS charge and discharge resistors
A pull-up resistor, RUP(VBUS), is provided to perform VBUS pulsing SRP. A B-device is
allowed to charge VBUS above the session valid threshold to request the host to turn on
the VBUS power.
A pull-down resistor, RDN(VBUS), is provided for a B-device to discharge VBUS. This is done
whenever the A-device turns off the VBUS power. The B-device can use the pull-down
resistor to ensure VBUS is below VB_SESS_END before starting a session.
For details, refer to On-The-Go Supplement to the USB 2.0 Specification Rev. 1.3.
9.13 Serial modes
The ISP1505 supports both 6-pin serial mode and 3-pin serial mode, controlled by
bits 6PIN_FSLS_SERIAL and 3PIN_FSLS_SERIAL of the Interface Control register. For
details, refer to UTMI+ Low Pin Interface (ULPI) Specification Rev. 1.1, Section 3.10.
Figure 18 and Figure 19 provide examples of 6-pin serial mode and 3-pin serial mode,
respectively.

9.14 Aborting transfers
The ISP1505 supports aborting transfers on the ULPI bus. For details, refer to UTMI+ Low
Pin Interface (ULPI) Specification Rev. 1.1, Section 3.8.4.
9.15 Avoiding contention on the ULPI data bus
Because the ULPI data bus is bidirectional, avoid situations in which both the link and the
PHY simultaneously drive the data bus.
The following points must be considered while implementing the data bus drive control on
the link.
After power-up and clock stabilization, default states are as follows:
• The ISP1505 drives DIR to LOW.
• The data bus is input to the ISP1505.
• The ULPI link data bus is output, with all data bus lines driven to LOW.
When the ISP1505 wants to take control of the data bus to initiate a data transfer, it
changes the DIR value from LOW to HIGH.
At this point, the link must disable its output buffers. This must be as fast as possible so
the link must use a combinational path from DIR.
The ISP1505 will not immediately enable its output buffers, but will delay the enabling of
its buffers until the next clock edge, avoiding bus contention.
When the data transfer is no longer required by the ISP1505, it changes DIR from HIGH to
LOW and starts to immediately turn off its output drivers. The link senses the change of
DIR from HIGH to LOW, but delays enabling its output buffers for one CLOCK cycle,
avoiding data bus contention.

Suspend LOW: Active LOW PHY suspend.
Places the PHY into low-power mode. The PHY will power down all blocks, except the
full-speed receiver, OTG comparators and ULPI interface pins.
To come out of low-power mode, the link must assert STP. The PHY will automatically clear
this bit when it exits low-power mode.

RESET
Reset: Active HIGH transceiver reset.
After the link sets this bit, the PHY will assert DIR and reset the digital core. This does not
reset the ULPI interface or the ULPI register set.
When reset is completed, the PHY will deassert DIR and automatically clear this bit, followed
by an RXCMD update to the link.

INTF_PROT_DIS
Interface Protect Disable: Controls circuitry built into the ISP1505 to protect the ULPI
interface when the link 3-states STP and DATA[7:0]. When this bit is enabled, the ISP1505
will automatically detect when the link stops driving STP.
0b — Enables the interface protect circuit (default). The ISP1505 attaches a weak pull-up
resistor on STP. If STP is unexpectedly HIGH, the ISP1505 attaches weak pull-down
resistors on DATA[7:0], protecting data inputs.
1b — Disables the interface protect circuit, detaches weak pull-down resistors on
DATA[7:0], and a weak pull-up resistor on STP.

IND_PASSTHRU
Indicator Pass-through: The ISP1505 does not support the qualification of an external
FAULT with the internal VA_VBUS_VLD comparator. Either a digital FAULT is input on the
V
BUS/FAULT pin or the VBUS power is connected to the VBUS/FAULT pin, not both. This bit
must always be set to logic 1.
0b — Not supported.
1b — The complement output signal is not qualified with the internal A_VBUS_VLD
comparator. The link must always set this bit to logic 1.
IND_COMPL
Indicator Complement: Informs the PHY to invert the FAULT input signal, generating the
complement output. For details, see Section 9.5.2.2.
0b — The ISP1505 will not invert the FAULT signal (default).
1b — The ISP1505 will invert the FAULT signal.

CLOCK_SUSPENDM Clock Suspend LOW: Active LOW clock suspend.
Powers down the internal clock circuitry only. By default, the clock will not be powered in
6-pin serial mode or 3-pin serial mode.
Valid only in 6-pin serial mode and 3-pin serial mode. Valid only when SUSPENDM is set to
logic 1, otherwise this bit is ignored.
0b — Clock will not be powered in 3-pin or 6-pin serial mode.
1b — Clock will be powered in 3-pin and 6-pin serial modes.

3PIN_FSLS_SERIAL
3-Pin Full-Speed Low-Speed Serial Mode: Changes the ULPI interface to a 3-bit serial
interface. The PHY will automatically clear this bit when 3-pin serial mode is exited.
0b — Full-speed or low-speed packets are sent using the parallel interface.
1b — Full-speed or low-speed packets are sent using the 3-pin serial interface.

18. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
18.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
18.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
• Board specifications, including the board finish, solder masks and vias
• Package footprints, including solder thieves and orientation
• The moisture sensitivity level of the packages
• Package placement
• Inspection and repair
• Lead-free soldering versus SnPb soldering
18.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

18.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 29) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 55 and 56

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 29.
