8-bit microcontroller
P83C562; P80C562
The P8xC562 contains 256 bytes of internal data RAM
and 52 Special Function Registers. It provides a
non-paged program memory address space to
accommodate relocatable code. Conditional branches are
performed relative to the Program Counter.
The register-indirect jump permits branching relative to a
16-bit base register with an offset provided by an 8-bit
index register. 16-bit jumps and calls permit branching to
any location in the contiguous 64 kbyte program memory
address space.
7
FUNCTIONAL DESCRIPTION
The P8xC562 is a stand-alone high-performance
microcontroller designed for use in real-time applications
such as instrumentation, industrial control and specific
automotive control applications.
In addition to the 80C51 standard functions, the device
provides a number of dedicated hardware functions for
these applications.
The P8xC562 is a control-oriented CPU with on-chip
program and data memory. It can be extended with
external program memory up to 64 kbytes. It can also
access up to 64 kbytes of external data memory.
For systems requiring extra capability, the P8xC562 can
be expanded using standard memories and peripherals.
8.1
Program Memory
The program memory address space of the P83C562
consists of internal and external memory. The P83C562
has 8 kbytes of program memory on-chip. The program
memory can be externally expanded up to 64 kbytes. If the
EA pin is held HIGH, the P83C562 executes out of the
internal program memory unless the address exceeds
1FFFH then locations 2000H through to 0FFFFH are
fetched from the external program memory. If the EA pin is
held LOW, the P83C562 fetches all instructions from the
external memory. Figure 4 illustrates the program
memory address space.
The P8xC562 has two software selectable modes of
reduced activity for further power reduction − Idle and
Power-down. The Idle mode freezes the CPU while
allowing the RAM, timers, serial ports and interrupt system
to continue functioning. The Power-down mode saves the
RAM contents but freezes the oscillator causing all other
chip functions to be inoperative.
By setting a mask programmable security bit (i.e. user
dependent) the ROM content is protected i.e. it cannot be
read at any time by any test mode or by any instruction in
the external program memory space. The MOVC
instructions are the only ones which have access to
program code in the internal or external program memory.
The EA input is latched during reset and is ‘don’t care’ after
reset. This implementation prevents from reading internal
program code by switching from the external program
memory to internal program memory during MOVC
instruction or an instruction that handles immediate data.
Table 2 lists the access to internal and external program
memory by the MOVC instructions when the security bit
has been set to a logic 1. If the security bit has been set to
a logic 0 there are no restrictions for the MOVC
instructions.
8
MEMORY ORGANIZATION
The Central Processing Unit (CPU) manipulates operands
in three memory spaces; these are the 64 kbyte external
data memory, 256 byte internal data memory and the
64 kbyte internal and external program memory.
The internal data memory is divided into 3 sections: the
lower 128 bytes of RAM, the upper 128 bytes of RAM and
the 128 byte Special Function Register memory
(see Fig.4). Figure 5 shows the Special Function
Registers memory map. Internal RAM locations 0 to 127
are directly and indirectly addressable. Internal RAM
locations 128 to 155 are only indirectly addressable.
The Special Function Register locations 128 to 255 are
only directly addressable.
The internal data RAM contains four register banks (each
with eight registers), 128 addressable bits, a scratch pad
area and the stack. The stack depth is limited by the
available internal data RAM and its location is determined
by the 8-bit Stack Pointer. All registers except the Program
Counter and the four 8-register banks reside in the
Special Function Register address space. These memory
mapped registers include arithmetic registers, pointers,
I/O ports, interrupt system registers, ADC and PWM
registers, timers and serial port registers. There are
120 addressable bit locations in the SFR address space.

• 256 bytes of internal data RAM through Direct or
Register-Indirect. Bytes 0 to 127 may be addressed
directly/indirectly. Bytes 128 to 155 share their address
locations with the SFR registers and so may only be
addressed indirectly as data RAM
8.2
Addressing
The P8xC562 has five methods for addressing source
operands:
• Register
• Direct
• Special Function Registers through Direct at address
locations 128 to 255
• Register-Indirect
• External data memory through Register-Indirect
• Immediate
• Program memory look-up tables through Base-Register
• Base-Register plus Index-Register-Indirect.
plus Index-Register-Indirect.
The first three methods can be used for addressing
destination operands. Most instructions have a
'destination/source' field that specifies the data type,
addressing methods and operands involved.
For operations other than MOVs, the destination operand
is also a source operand.
The P8xC562 is classified as an 8-bit device since the
internal ROM, RAM, Special Function Registers,
Arithmetic Logic Unit and external data bus are all 8-bits
wide. It performs operations on bit, nibble, byte and
double-byte data types.
Facilities are available for byte transfer, logic and integer
arithmetic operations. Data transfer, logic and conditional
branch operations can be performed directly on Boolean
variables to provide excellent bit handling.
Access to memory addressing is as follows:
• Registers in one of the four 8-register banks through

I/O FACILITIES
The P8xC562 has six 8-bit ports. Ports 0 to 3 are the same
as in the 80C51, with the exception of the additional
functions of Port 1. The parallel I/O function of Port 4 is
equal to that of Ports 1, 2 and 3. Port 5 has a parallel input
port function, but has no function as an output port.
Port 5 May be used in conjunction with the ADC interface.
Unused analog inputs can be used as digital inputs.
As Port 5 lines may be used as inputs to the ADC,
these digital inputs have an inherent hysteresis to
prevent the input logic from drawing too much
current from the power lines when driven by analog
signals. Channel-to-channel crosstalk should be
taken into consideration when both digital and
analog signals are simultaneously input to Port 5
(see Chapter 20).
Ports 0 to 5 perform the following alternative functions:
Port 0 Provides the multiplexed low-order address and
data bus used for expanding the P8xC562 with
standard memories and peripherals.
Port 1 is used for a number of special functions:
• 4 capture inputs (or external interrupt request inputs if
capture information is not utilized)
All ports are bidirectional with the exception of Port 5 which
is an input port. Alternative function bits which are not used
may be used as normal bidirectional I/O pins.
The generation or use of a Port 1, Port 3 or Port 4 pin as
an alternative function is carried out automatically by the
P8xC562 provided the associated Special Function
Register bit is set HIGH.
• External counter input
• External counter reset input.
Port 2 Provides the high-order address bus when
expanding the P8xC562 with external program
memory and/or external data memory.
In addition to the standard 8-bit ports, the I/O facilities of
the P8xC562 also include a number of special I/O lines.
Port 3 Pins can be configured individually to provide:
• External interrupt request inputs
• Counter inputs
• Serial port receiver input and transmitter output
• Control signals to READ and WRITE external data
memory.

The pulse width ratio is in the range of 0 to 255/255 and
may be programmed in increments of 1/255.
10 PULSE WIDTH MODULATED OUTPUTS
Two pulse width modulated output channels are provided
with the P8xC562. These channels output pulses of
programmable length and interval. The repetition
frequency is defined by an 8-bit prescaler PWMP which
generates the clock for the counter. Both the prescaler and
counter are common to both PWM channels. The 8-bit
counter counts modulo 255 i.e. from 0 to 254 inclusive.
The value of the 8-bit counter is compared to the contents
of two registers: PWM0 and PWM1.
The repetition frequency fPWM, at the PWMn outputs is
fOSC
given by: fPWM
=
------------------------------------------------------------
2 × (1 + PWMP) × 255
When using an oscillator frequency of 16 MHz for
example, the above formula would give a repetition
frequency range of 123 Hz to 31.4 kHz.
By loading the PWM registers with either 00H or FFH, the
PWM outputs can be retained at a constant HIGH or LOW
level respectively. When loading FFH to the PWM
registers, the 8-bit counter will never actually reach this
value. Both PWMn output pins are driven by push-pull
drivers, and are not shared with any other function.
Provided the contents of either of these registers is greater
than the counter value, the output of PWM0 or PWM1 is
set LOW. If the contents of these registers are equal to, or
less than the counter value, the output will be HIGH.
The pulse width ratio is therefore defined by the contents
of the registers PWM0 and PWM1.

11 ANALOG-TO-DIGITAL CONVERTER (ADC)
11.1 Analog input pins
The completion of the 8-bit ADC conversion is flagged by
ADCI in the ADCON register and the result is stored in
Special Function Register ADCH.
The analog input circuitry consists of an 8-input analog
multiplexer and an ADC with 8-bit resolution. The analog
reference voltage and analog power supplies are
connected via separate input pins. The conversion takes
24 machine cycles i.e. 18 µs at an oscillator frequency of
16 MHz.
An ADC conversion in progress is unaffected by an
external or software ADC start. The result of a completed
conversion remains unaffected provided ADCI = 1. While
ADCS = 1 or ADCI = 1, a new ADC start will be blocked
and consequently lost.
The ADC is controlled using the ADC Control Register
(ADCON). Input channels are selected by the analog
multiplexer, using bits AADR.0 to AADR.2 in ADCON.
An ADC conversion already in progress is aborted when
the Idle or Power-down mode is entered. The result of a
completed conversion (ADCI = 1) remains unaffected
when entering the Idle mode.
If ADCI is cleared by software and ADCS is set at the same
time, a new analog-to-digital conversion with the same
channel number, may be started. However, it is
recommended to reset ADCI before ADCS is set.

ADCI cannot be set by software.
ADCS
ADC start and status: setting this bit starts an ADC conversion. It may be set by
software or by the external signal STADC. The ADC logic ensures that this signal is
HIGH while the ADC is busy. On completion of the conversion, ADCS is reset
immediately after the interrupt flag has been set. ADCS can not be reset by software nor
can a new conversion be started if either ADCS or ADCI is HIGH.

12 TIMER/ COUNTERS
12.2 Timer T2 Capture and Compare Logic
The P8xC562 contains:
Timer T2 is a 16-bit timer/counter which has, coupled to it,
capture and compare facilities. The operational diagram is
shown in Fig.10.
• Three 16-bit timer/event counters: Timer 0, Timer 1 and
Timer 2
The 16-bit timer/counter is clocked via a prescaler with a
programmable division factor of 1, 2, 4 or 8. The input of
the prescaler is clocked with 1⁄12 of the oscillator
frequency, or with positive edges on the T2 input, or it is
switched to the off position. The prescaler is cleared if its
division factor or its input source is changed, or if the
timer/counter is reset. T2 is readable on-the-fly, but
possesses no extra read latches; this means that software
precautions have to be taken against misinterpretation on
overflow from least to most significant byte during a read.
T2 is not loadable and is reset by the RST signal or at the
positive edge of the input signal RT2, if enabled. In the Idle
mode the timer/counter and prescaler are reset and
halted.
• One 8-bit Watchdog Timer.
12.1 Timer 0 and Timer 1
Timer 0 and Timer 1 may be programmed to carry out the
following operations:
• Measure time intervals and pulse durations
• Count events
• Generate interrupt requests.
Timer 0 and Timer 1 can also be programmed
independently to operate in three modes:
Mode 0 8-bit timer or 8-bit counter each with
divide-by-32 prescaler
T2 is connected to four 16-bit Capture Registers: CT0,
CT1, CT2 and CT3. These registers are loaded with the
contents of T2 and an interrupt is requested upon receipt
of the input signals CT0I, CT1I, CT2I or CT3I. These input
signals are shared with Port 1. Using the Capture Register
(CTCON), these inputs may invoke capture and interrupt
request on a positive or negative edge or on both edges.
If neither a positive nor a negative edge is selected for a
capture input, no capture or interrupt request can be
generated by this input.
Mode 1 16-bit time-interval or event counter
Mode 2 8-bit time-interval or event counter with automatic
reload upon overflow.
Timer 0 can be programmed to operate in an additional
mode as follows:
Mode 3 one 8-bit time-interval or event counter and one
8-bit time-interval counter.
When Timer 0 is in Mode 3, Timer 1 can be programmed
to operate in Modes 0, 1 or 2 but cannot set an interrupt
request flag or generate an interrupt. However, the
overflow from Timer 1 can be used to pulse the serial port
transmission-rate generator.
The contents of the Compare Registers CM0, CM1 and
CM2 are continually compared with the counter value of
Timer 2. When a match is found an interrupt may be
invoked. Using the match signal of CM0, the controller sets
bits 0 to 5 of Port 4, if the corresponding bits of the Set
Enable Register are logic 1s.
The frequency handling range of these counters with a
16 MHz crystal is as follows:
Considering a match with CM1, if the corresponding bits of
the Reset/toggle Enable Register (RTE) are logic 1, then
the controller will use the match signal to reset bits 0 to 5
of Port 4. Bits 6 and 7 of Port 4 may be toggled by the
signal that indicates a match of Timer T2 and CM2 if the
corresponding bits of RTE are logic 1. CM0, CM1 and CM2
are reset by the RST signal.
• In the timer function, the timer is incremented at a
frequency of 1.33 MHz; a division by 12 of the oscillator
frequency
• 0 Hz to an upper limit of 0.66 MHz when programmed
for external inputs.
Both internal and external inputs can be gated to the
counter by a second external source for directly measuring
pulse durations.
Port 4 can be read and written by software without
affecting the toggle, set and reset signals. At byte overflow
of the least significant byte, or at a 16-bit overflow of the
timer/counter, an interrupt sharing the same interrupt
vector is requested. Either one or both of these overflows
can be programmed to request an interrupt.
The counters are started and stopped under software
control. Each one sets its interrupt request flag when it
overflows from all logic 1s to all logic 0s (or automatic
reload value), with the exception of Mode 3 as previously
described.
All interrupt flags must be reset by software.

The Watchdog Timer can only be reloaded if the condition
flag WLE in the Power Control Register has been
previously set by software. At the moment the counter is
loaded the condition flag is automatically cleared.
The timer interval between the timer's reloading and
occurrence of a reset, is dependent upon the reloaded
value. For example, this may range from 2 ms to 0.5 s
when using an oscillator frequency of 12 MHz. In the Idle
state the Watchdog Timer and reset circuitry remain
active.
12.3 Watchdog Timer (T3)
In addition to Timer T2 and the standard timers, a
Watchdog Timer is also available, consisting of an 11-bit
prescaler and a 8-bit timer. The functional diagram of the
Watchdog Timer is shown in Fig.11. The timer is
incremented every t seconds,
12 × 2048
t =
-------------------------
where:
fOSC
When a timer overflow occurs, the microcontroller is reset
and a reset output pulse is generated at the RST pin.
The Watchdog Timer is controlled by the Enable
Watchdog pin (EW). A logic 0 enables the Watchdog
Timer and disables the Power-down mode. A logic 1
disables the Watchdog Timer and enables the
Power-down mode.
To prevent a system reset the timer must be reloaded in
time by the application software. If the processor suffers a
hardware/ software malfunction, the software will fail to
reload the timer. This failure will produce a reset upon
overflow thus preventing the processor running out of
control.

the execution of any particular section of code. To tie the
asynchronous activities of these functions to normal
program execution a multiple-source, two-priority-level,
nested interrupt system is provided. The interrupt system

be used as a positive and/or negative edge triggered
external interrupt.
14.2 Interrupt priority
Each interrupt source can be either high priority or low
priority. If both priorities are requested simultaneously, the
processor will branch to the high priority vector. If there are
simultaneous requests from sources of the same priority,
then interrupts will be serviced in the following order:
• ADC conversion completed interrupt
• UART serial I/O port interrupt.
Each interrupt vectors to a separate location in program
memory for its service routine. Each source can be
individually enabled or disabled by a corresponding bit in
the IEN0 or IEN1 registers, in addition each interrupt may
be programmed to a high or low priority level using the
corresponding bit in the IP0 or IP1 registers. All enabled
sources can be globally disabled or enabled. Both external
interrupts can be programmed to be level-activated or
transition-activated; an active LOW level allows
X0, ADC, T0, CT0, CM0, X1, CT1, CM1, T1, CT2, CM2,
S0, CT3, T2.
A low priority interrupt routine can only be interrupted by a
high priority interrupt. A high priority interrupt routine can
not be interrupted.

The interrupt is serviced, and following the return from
interrupt instruction RETI, the next instruction to be
executed will be the one which follows the instruction
that wrote a logic 1 to PCON.0. The flag bits GF0 and
GF1 may be used to determine whether the interrupt
was received during normal execution or during the Idle
mode. For example, the instruction that writes to
PCON.0 can also set or clear one or both flag bits. When
Idle mode is terminated by an interrupt, the service
routine can examine the status of the flag bits.
15 REDUCED POWER MODES
15.1 Idle and Power-down operation
Idle mode operation permits the interrupt, serial ports and
timer blocks to continue to function while the CPU is
halted. The Idle and Power-down clock configuration is
shown in Fig.13. The following functions are switched off
when the processor enters the Idle mode.
• Timer T2 - stopped and reset
• PWM0 and PWM1 - reset, output HIGH
• ADC - aborted if in progress.
• The second way of terminating the Idle mode is with an
external hardware reset, or an internal reset caused by
an overflow of the Watchdog Timer (T3). Since the
oscillator is still running, the hardware reset is required
to be active for two machine cycles (24 oscillator periods
but at least 2 µs) to complete the reset operation.
The following functions remain active during Idle mode.
These functions may generate an interrupt or reset and
thus end the Idle mode.
• Timer 0, Timer 1
• Timer T3
15.1.2 POWER-DOWN MODE
• SIO
The instruction that sets PCON.1 is the last executed prior
to going into the Power-down mode. Once in Power-down
mode, the oscillator is stopped. Only the contents of the
on-chip RAM are preserved. The Special Function
Registers are not saved. A hardware reset is the only way
of exiting the Power-down mode.
• External Interrupt.
The Power-down operation freezes the oscillator.
The Power-down mode can only be activated by setting
the PD bit in the PCON register. The PD bit can only be set
if the EW input is HIGH.
In the Power-down mode, VDD may be reduced to
minimize circuit power consumption. The supply voltage
must not be reduced until the Power-down mode is
entered, and must be restored before the hardware reset
is applied which will free the oscillator. Reset should not be
released until the oscillator has restarted and stabilized.
15.1.1 IDLE MODE
The instruction that sets PCON.0 is the last instruction
executed in the normal operating mode before Idle mode
is activated. Once in the Idle mode, the CPU status is
preserved in its entirety: the Stack Pointer, Program
Counter, Program Status Word, Accumulator, RAM and all
other registers maintain their data during Idle mode.
The status of the external pins during Idle mode is shown
in Table 33.
The status of the external pins during Power-down mode
is shown in Table 33. If the Power-down mode is activated
while in external program memory, the port data that is
held in the Special Function Register P2 is restored to
Port 2. If the data is a logic 1, the port pin is held HIGH
during the Power-down mode by the strong pull-up
transistor p1 (see Fig.7).
There are two ways to terminate the Idle mode:
• Activation of any enabled interrupt will cause PCON.0 to
be cleared by hardware terminating the Idle mode.

16 OSCILLATOR CIRCUITRY
, halfpage
The oscillator circuitry of the P8xC562 is a single-stage
inverting amplifier in a Pierce oscillator configuration.
The circuitry between XTAL1 and XTAL2 is basically an
inverter biased to the transfer point. Either a crystal or
ceramic resonator can be used as the feedback element to
complete the oscillator circuitry. Both are operated in
parallel resonance. XTAL1 (pin 35) is the high gain
amplifier input, and XTAL2 (pin 34) is the output (see
Fig.14). To drive the P8xC562 externally, XTAL1 is driven
from an external source and XTAL2 left open-circuit (see
Fig.15).

17 RESET CIRCUITRY
Fig.14 P8xC562P8xC562 oscillator circuit.
The reset circuitry for the P8xC562 is connected to the
reset pin RST. A Schmitt trigger is used at the input for
noise rejection. The output of the Schmitt trigger is
sampled by the reset circuitry every machine cycle.
The on-chip Reset circuit is shown in Fig.16.
ook, halfpage

XTAL1
A reset is accomplished by holding the RST pin HIGH for
at least two machine cycles (24 oscillator periods but at
least 2 µs). The CPU responds by executing an internal
reset. During reset both ALE and PSEN output a HIGH
level. In order to perform a correct reset, this level must not
be affected by external elements.

not connected
Also with the P8xC562, the RST line can be pulled HIGH
internally by a pull-up transistor activated by the Watchdog
Timer (T3). The length of the output pulse from the
Watchdog Timer is 3 machine cycles. A pulse of such
short duration is necessary in order to recover from a
processor or system fault as fast as possible.
MGA169
Fig.15 Driving the P8xC562 from an external source.
It can be seen that the short reset pulse from T3 cannot
discharge the Power-on reset capacitor (see Fig.17).
Consequently, when the Watchdog Timer is also used to
reset external devices this capacitor arrangement should
not be connected to the RST pin, and an extra circuit
should be used to perform the Power-on-reset operation.
It should be remembered that a T3 overflow, if enabled, will
force a reset condition to the P8xC562 by an internal
connection, whether the output RST is tied LOW or not.

The internal reset is executed during the second cycle in

Table 36 State of internal registers after an internal reset
17.1 Power-on-reset
X = undefined state.
When VDD is turned on, and provided its rise-time does not
exceed 10 ms, an automatic reset can be obtained by
connecting the RST pin to VDD via a 2.2 µF capacitor.
When the power is switched on, the voltage on the RST
pin, is equal to VDD minus the capacitor voltage, and
decreases from VDD as the capacitor charges through the
internal resistor (RRST) to ground. The larger the capacitor,
the more slowly VRST decreases. VRST must remain above
the lower threshold of the Schmitt trigger long enough to
effect a complete reset. The time required is the oscillator
start-up time, plus 2 machine cycles. The port pins will be
in a random state until the oscillator has started and the
internal reset algorithm has written logic 1s to the port pins.
The Power-on-reset circuitry is shown in Fig.17.

Notes to the DC characteristics
1. The operating supply current is measured with all output pins disconnected;
XTAL1 driven with tr = tf = 10 ns; VIL = VSS + 0.5 V; VIH = VDD − 0.5 V; XTAL2 not connected;
EA = RST = Port 0 = EW = VDD; STADC = VSS
.
2. The Idle mode supply current is measured with all output pins disconnected;
XTAL1 driven with tr = tf = 10 ns; VIL = VSS + 0.5 V; VIH = VDD − 0.5 V; XTAL2 not connected;
EA = Port 0 = EW = VDD; RST = STADC = VSS
3. The Power-down current is measured with all output pins disconnected; XTAL2 not connected;
EA = Port 0 = EW = VDD; RST = STADC = XTAL1 = VSS
.
.
4. Capacitive loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the low level output
voltage of ALE and Ports 1, 3 and 4. The noise is due to external bus capacitance discharging into the Port 0 and
Port 2 pins when these pins make HIGH-to-LOW transitions during bus operations. In the most adverse condition
(capacitive loading > 100 pF), the noise pulse on the ALE line may exceed 0.8 V. In such events it may be required
to qualify ALE with a Schmitt trigger, or use an address latch with a Schmitt trigger strobe input.
5. Capacitive loading on Ports 0 and 2 may cause the high level output voltage on ALE and PSEN to momentarily fall
below to 0.9VDD specification when the address bits are stabilizing.
6. VREF+ = 5.12 V; VREF− = 0 V; VDDA = 5.0 V.
7. The differential non-linearity (DLe) is the difference between the actual step width and the ideal step width.
8. The integral non-linearity (ILe) is the peak difference between the centre of the steps of the actual and the ideal
transfer curve after appropriate adjustment of gain and offset error.
9. The gain error (Ge) is the relative difference in percent between the straight line fitting the actual transfer curve after
removing offset error, and the straight line which fits the ideal transfer curve. Gain error is constant at every point on
the transfer curve.
10. The offset error (OSe) is the absolute difference between the straight line which fits the actual transfer curve after
removing gain error, and a straight line which fits the ideal transfer curve. The offset error is constant at every point
of the actual transfer curve.
11. VREF− = 0 V; VDDA = 5 V; VREF+ = 5.12 V. The ADC is monotonic with no missing codes. Measurement by
continuously increasing VIN from −20 mV to 5.12 V in increments of 2 mV.

AC inputs during testing are driven at VDD − 0.5 V for a logic 1, and 0.45 V for a logic 0.
Timing measurements are made at VIH(min) for a logic 1, and VIL(max) for a logic 0. See Fig.25 (a).
For timing purposes a port pin is no longer floating when a 100 mV change from load voltage occurs. A port pin begins to float when a
100 mV change from the loaded VOH/VOL level occurs. IOL/IOH ≥ ±20 mA (for testing purposes only). See Fig.25 (b).

23 SOLDERING
23.3 Wave soldering
Wave soldering techniques can be used for all PLCC
packages if the following conditions are observed:
23.1 Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
• The package footprint must incorporate solder thieves at
the downstream corners.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
23.2 Reflow soldering
Reflow soldering techniques are suitable for all PLCC
packages.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
The choice of heating method may be influenced by larger
PLCC packages (44 leads, or more). If infrared or vapour
phase heating is used and the large packages are not
absolutely dry (less than 0.1% moisture content by
weight), vaporization of the small amount of moisture in
them can cause cracking of the plastic body. For more
information, refer to the Drypack chapter in our “Quality
Reference Handbook” (order code 9397 750 00192).
6 seconds. Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
23.4 Repairing soldered joints
Fix the component by first soldering two diagonally-
opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
