INTRODUCTION
General Description
The Microchip USB7016 hub is a low-power, OEM configurable, USB 3.2 Gen 1 hub controller with 6 downstream ports
and advanced features for embedded USB applications. The USB7016 is fully compliant with the Universal Serial Bus
Revision 3.2 Specification and USB 2.0 Link Power Management Addendum. The USB7016 supports 5 Gbps Super-
Speed+ (SS+), 5 Gbps SuperSpeed (SS), 480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-
Speed (LS) USB downstream devices on four standard USB 3.2 Gen 1 downstream ports and only legacy speeds (HS/
FS/LS) on two standard USB 2.0 downstream ports.
The USB7016 is a standard USB 3.2 Gen 1 hub that supports native basic Type-C with integrated CC logic on down-
stream port 1. The downstream Type-C port includes an internal USB 3.2 Gen 1 multiplexer; no external multiplexer is
required for Type-C support.
The USB7016 supports the legacy USB speeds (HS/FS/LS) through a dedicated USB 2.0 hub controller that is the cul-
mination of seven generations of Microchip hub feature controller design and experience with proven reliability, interop-
erability, and device compatibility. The SuperSpeed hub controller operates in parallel with the USB 2.0 controller,
decoupling the 5 Gbps SS+/SS data transfers from bottlenecks due to the slower USB 2.0 traffic.
The USB7016 enables OEMs to configure their system using “Configuration Straps.” These straps simplify the config-
uration process assigning default values to USB 3.2 Gen 1 ports and GPIOs. OEMs can disable ports, enable battery
charging and define GPIO functions as default assignments on power up removing the need for OTP or external SPI
ROM.
The USB7016 supports downstream battery charging. The USB7016 integrated battery charger detection circuitry sup-
ports the USB-IF Battery Charging (BC1.2) detection method and most Apple devices. The USB7016 provides the bat-
tery charging handshake and supports the following USB-IF BC1.2 charging profiles:
• DCP: Dedicated Charging Port (Power brick with no data)
• CDP: Charging Downstream Port (1.5A with data)
• SDP: Standard Downstream Port (0.5A[USB 2.0]/0.9A[USB 3.2] with data)
Additionally, the USB7016 includes many powerful and unique features such as:
The Hub Feature Controller, an internal USB device dedicated for use as a USB to I2C/SPI/GPIO interface that allows
external circuits or devices to be monitored, controlled, or configured via the USB interface.
FlexConnect, which provides flexible connectivity options. One of the USB7016’s downstream ports can be reconfig-
ured to become the upstream port, allowing master capable devices to control other devices on the hub.
AEC-Q100 compliance, which tailors the device for use in automotive applications requiring automotive grade robust-
ness, starting with the comprehension of proprietary design for reliability techniques within the silicon IC itself, as well
as for the package design.
• Automotive qualified technologies and processes are used to fabricate the products with enhanced monitors to
continuously drive improvements in accordance with Microchip's zero-dpm methodology.
• Product qualification is focused on customer expectations and exceeds many of the automotive reliability stan-
dards including AEC-Q100.
• Microchip automotive services are provided during the life of the product from a dedicated organization of opera-
tions, quality, and product support personnel specialized in meeting the requirements of the automotive customer.
PortSwap, which adds per-port programmability to USB differential-pair pin locations. PortSwap allows direct alignment
of USB signals (D+/D-) to connectors to avoid uneven trace length or crossing of the USB differential signals on the
PCB.
PHYBoost, which provides programmable levels of Hi-Speed USB signal drive strength
in the downstream port transceivers. PHYBoost attempts to restore USB signal integrity
in a compromised system environment. The graphic on the right shows an example of
Hi-Speed USB eye diagrams before and after PHYBoost signal integrity restoration. in
a compromised system environment.
VariSense, which controls the Hi-Speed USB receiver sensitivity enabling programmable levels of USB signal receive
sensitivity. This capability allows operation in a sub-optimal system environment, such as when a captive USB cable is
used.
DS00003740A-page 6

USB7016
Port Split, which allows for the USB 3.2 Gen 1 and USB 2.0 portions of downstream ports 2, 3, and 4 in Configuration
1 and downstream port 4 (only) in Configuration 2 to operate independently and enumerate two separate devices in
parallel in special applications.
USB Power Delivery Billboard Device, which allows an internal device to enumerate as a Billboard class device when
a Power Delivery Alternate Mode negotiation has failed. The Billboard device will enumerate temporarily to the host PC
when a failure occurs, as indicated by a digital signal from an external Power Delivery controller.
The USB7016 can be configured for operation through internal default settings. Custom OEM configurations are sup-
ported through external SPI ROM or OTP ROM. All port control signal pins are under firmware control in order to allow
for maximum operational flexibility and are available as GPIOs for customer specific use.
The USB7016 is available in commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature range. An internal
block diagram of the USB7016 in an upstream Type-B application is shown in Figure 2-1.

Note:
All port numbering in this document is LOGICAL port numbering with the device in the default configuration.
LOGICAL port numbering is the numbering as communicated to the USB host. It is the end result after any
port number remapping or port disabling. The PHYSICAL port number is the port number with respect to
the physical PHY on the chip. PHYSICAL port numbering is fixed and the settings are not impacted by
LOGICAL port renumbering/remapping. Certain port settings are made with respect to LOGICAL port num-
bering, and other port settings are made with respect to PHYSICAL port numbering. Refer to the “Config-
uration of USB70xx Family” application note for details on the LOGICAL vs. PHYSICAL mapping and
additional configuration details.

Pin Descriptions
This section contains descriptions of the various USB7016 pins. The “_N” symbol in the signal name indicates that the
active, or asserted, state occurs when the signal is at a low voltage level. For example, RESET_N indicates that the
reset signal is active low. When “_N” is not present after the signal name, the signal is asserted when at the high voltage
level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of
“active low” and “active high” signal. The term assert, or assertion, indicates that a signal is active, independent of
whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inac-
tive.
The “If Unused” column provides information on how to terminate pins if they are unused in a customer design.

Configuration Straps and Programmable Functions
Configuration straps are multi-function pins that are used during Power-On Reset (POR) or external chip reset
(RESET_N) to determine the default configuration of a particular feature. The state of the signal is latched following
deassertion of the reset. Configuration straps are identified by an underlined symbol name. This section details the var-
ious device configuration straps and associated programmable pin functions.
Note:
The system designer must guarantee that configuration straps meet the timing requirements specified in
Section 9.6.2, Power-On and Configuration Strap Timing and Section 9.6.3, Reset and Configuration Strap
Timing. If configuration straps are not at the correct voltage level prior to being latched, the device may
capture incorrect strap values.

The PRT_DIS_P[6:1] / PRT_DIS_M[6:1] configuration straps are used in conjunction to disable the related port (6-1)
For PRT_DIS_Px (where x is the corresponding port 6-1):
0 = Port x D+ Enabled
1 = Port x D+ Disabled
For PRT_DIS_Mx (where x is the corresponding port 6-1):
0 = Port x D- Enabled
1 = Port x D- Disabled
Note:
Both PRT_DIS_Px and PRT_DIS_Mx (where x is the corresponding port) must be tied to 3.3 V to disable
the associated downstream port. Disabling the USB 2.0 port will also disable the corresponding USB 3.0
port.

Physical and Logical Port Mapping
The USB70xx family of devices are based upon a common architecture, but all have different modifications and/or pin
bond outs to achieve the various device configurations. The base chip is composed of a total of 6 USB3 PHYs and 7
USB2 PHYs. These PHYs are physically arranged on the chip in a certain way, which is referred to as the PHYSICAL
port mapping.
The actual port numbering is remapped by default in different ways on each device in the family. This changes the way
that the ports are numbered from the USB host’s perspective. This is referred to as LOGICAL mapping.
The various configuration options available for these devices may, at times, be with respect to PHYSICAL mapping or
LOGICAL mapping. Each individual configuration option which has a PHYSICAL or LOGICAL dependency is declared
as such within the register description.
The PHYSICAL vs. LOGICAL mapping is described for all port related pins in Table 3-7. A system design in schematics
and layout is generally performed using the pinout in Section 3.1, Pin Assignments, which is assigned by the default
LOGICAL mapping. Hence, it may be necessary to cross reference the PHYSICAL vs. LOGICAL look up tables when
determining the hub configuration.
Note:
The MPLAB Connect tool makes configuration simple; the settings can be selected by the user with respect
to the LOGICAL port numbering. The tool handles the necessary linking to the PHYSICAL port settings.
Refer to Section 6.0, Device Configuration for additional information.

MODES OF OPERATION
The device provides two main modes of operation: Standby Mode and Hub Mode. These modes are controlled via the
RESET_N pin, as shown in Table 5-1.
TABLE 5-1:
MODES OF OPERATION
RESET_N Input
0
Summary
Standby Mode: This is the lowest power mode of the device. No functions are active
other than monitoring the RESET_N input. All port interfaces are high impedance and
the PLL is halted. Refer to Section 8.10, Resets for additional information on
RESET_N.

Hub (Normal) Mode: The device operates as a configurable USB hub. This mode has
various sub-modes of operation, as detailed in Figure 5-1. Power consumption is based
on the number of active ports, their speed, and amount of data received.
The flowchart in Figure 5-1 details the modes of operation and details how the device traverses through the Hub Mode
stages (shown in bold). The remaining sub-sections provide more detail on each stage of operation.

5.1
Boot Sequence
5.1.1
STANDBY MODE
If the RESET_N pin is asserted, the hub will be in Standby Mode. This mode provides a very low power state for maxi-
mum power efficiency when no signaling is required. This is the lowest power state. In Standby Mode all downstream
ports are disabled, the USB data pins are held in a high-impedance state, all transactions immediately terminate (no
states saved), all internal registers return to their default state, the PLLis halted, and core logic is powered down in order
to minimize power consumption. Because core logic is powered off, no configuration settings are retained in this mode
and must be re-initialized after RESET_N is negated high.
5.1.2
SPI INITIALIZATION STAGE (SPI_INIT)
The first stage, the initialization stage, occurs on the deassertion of RESET_N. In this stage, the internal logic is reset,
the PLL locks if a valid clock is supplied, and the configuration registers are initialized to their default state. The internal
firmware then checks for an external SPI ROM. The firmware looks for an external SPI flash device that contains a valid
signature of “2DFU” (device firmware upgrade) beginning at address 0x3FFFA. If a valid signature is found, then the
external SPI ROM is enabled and the code execution begins at address 0x0000 in the external SPI device. If a valid
signature is not found, then execution continues from internal ROM (CFG_ROM stage).
The required SPI ROM must be a minimum of 1 Mbit, and 60 MHz or faster. Both 1, 2, and 4-bit SPI operation is sup-
ported. For optimum throughput, a 2-bit SPI ROM is recommended. Both mode 0 and mode 3 SPI ROMs are also sup-
ported.
If the system is not strapped for SPI Mode, code execution will continue from internal ROM (CFG_ROM stage).
5.1.3
CONFIGURATION FROM INTERNAL ROM STAGE (CFG_ROM)
In this stage, the internal firmware loads the default values from the internal ROM. Most of the hub configuration regis-
ters, USB descriptors, electrical settings, etc. will be initialized in this state.
5.1.4
CONFIGURATION STRAP READ STAGE (CFG_STRAP)
In this stage, the firmware reads the following configuration straps to override the default values:
• CFG_STRAP[3:1]
• PRT_DIS_P[6:1]
• PRT_DIS_M[6:1]
• CFG_NON_REM
• CFG_BC_EN
If the CFG_STRAP[3:1] pins are set to Configuration 1, the device will move to the SMBUS_CHECK stage, otherwise
it will move to the CFG_OTP stage. Refer to Section 3.3, Configuration Straps and Programmable Functions for infor-
mation on usage of the various device configuration straps.
5.1.5
SMBUS CHECK STAGE (SMBUS_CHECK)
Based on the PF[31:3] configuration selected (refer to Section 3.3.4, PF[31:3] Configuration (CFG_STRAP[2:1])), the
firmware will check for the presence of external pull up resistors on the SMBus slave programmable function pins. If 10K
pull-ups are detected on both pins, the device will be configured as an SMBus slave, and the next state will be CFG_SM-
BUS. If a pull-up is not detected in either of the pins, the next state is CFG_OTP.
5.1.6
SMBUS CONFIGURATION STAGE (CFG_SMBUS)
In this stage, the external SMBus master can modify any of the default configuration settings specified in the integrated
ROM, such as USB device descriptors, port electrical settings, and control features such as downstream battery
charging.
There is no time limit on this mode. In this stage the firmware will wait indefinitely for the SMBus/I2C configuration. The
external SMBus master writes to register 0xFF to end the configuration in legacy mode. In non-legacy mode, the SMBus
command USB_ATTACH (opcode 0xAA55) or USB_ATTACH_WITH_SMBUS (opcode 0xAA56) will finish the configu-
ration.
2021 Microchip Technology Inc.
DS00003740A-page 29
USB7016
5.1.7
OTP CONFIGURATION STAGE (CFG_OTP)
Once the SOC has indicated that it is done with configuration, all configuration data is combined in this stage. The
default data, the SOC configuration data, and the OTP data are all combined in the firmware and the device is pro-
grammed.
Note:
If the same register is modified in both CFG_SMBUS and CFG_OTP stages, the value from CFG_OTP will
overwrite any value written during CFG_SMBUS.
5.1.8
HUB CONNECT STAGE (USB_ATTACH)
Once the hub registers are updated through default values, SMBus master, and OTP, the device firmware will enable
attaching the USB host by setting the USB_ATTACH bit in the HUB_CMD_STAT register (for USB 2.0) and the
USB3_HUB_ENABLE bit (for USB 3.2). The device will remain in the Hub Connect stage indefinitely.
5.1.9
NORMAL MODE (NORMAL_MODE)
Lastly, the hub enters Normal Mode of operation. In this stage full USB operation is supported under control of the USB
Host on the upstream port. The device will remain in the normal mode until the operating mode is changed by the sys-
tem.
If RESET_N is asserted low, then Standby Mode is entered. The device may then be placed into any of the designated
hub stages. Asserting a soft disconnect on the upstream port will cause the hub to return to the Hub Connect stage until
the soft disconnect is negated.

design-centers/usb/mplab-connect-configurator.
7.1
SPI/SQI Master Interface
The SPI/SQI controller has two basic modes of operation: execution of an external hub firmware image, or the USB to
SPI bridge. On power up, the firmware looks for an external SPI flash device that contains a valid signature of 2DFU
(device firmware upgrade) beginning at address 0x3FFFA. If a valid signature is found, then the external ROM mode is
enabled and the code execution begins at address 0x0000 in the external SPI device. If a valid signature is not found,
then execution continues from internal ROM and the SPI interface can be used as a USB to SPI bridge.
The entire firmware image is then executed in place entirely from the SPI interface. The SPI interface will remain con-
tinuously active while the hub is in the runtime state. The hub configuration options are also loaded entirely out of the
SPI memory device. Both the internal ROM firmware image and internal OTP memory are completely ignored while exe-
cuting the firmware and configuration from the external SPI memory.
The second mode of operation is the USB to SPI bridge operation. Additional details on this feature can be found in
Section 8.8, USB to SPI Bridging.

7.2
SMBus/I2C Master/Slave Interfaces
The device provides three independent SMBus/I2C controllers (Slave, Master, and Power Delivery Master) which can
be used to access internal device run time registers or program the internal OTP memory. The device contains two 128
byte buffers to enable simultaneous master/slave operation and to minimize firmware overhead in processed I2C pack-
ets. The I2C interfaces support 100KHz Standard-mode (Sm) and 400KHz Fast Mode (Fm) operation.
The SMBus/I2C interfaces are assigned to programmable pins (PFx) and therefore the device must be programmed into
specific configurations to enable specific interfaces. Refer to Section 3.3.4, PF[31:3] Configuration (CFG_STRAP[2:1])
for additional information.
Note:
For SMBus/I2C timing information, refer to Section 9.6.7, SMBus Timing and Section 9.6.8, I2C Timing.
7.3
I2S Interface
The device provides an integrated I2S interface to facilitate the connection of digital audio devices. The I2S interface
conforms to the voltage, power, and timing characteristics/specifications as set forth in the I2S-Bus Specification, and
consists of the following signals:
• I2S_SDI: Serial Data Input
• I2S_SDO: Serial Data Output
• I2S_SCK: Serial Clock
• I2S_LRCK: Left/Right Clock (SS/FSYNC)
• I2S_MCLK: Master Clock
• MIC_DET: Microphone Plug Detect
Each audio connection is half-duplex, so I2S_SDO exists only on the transmit side and I2S_SDI exists only on the
receive side of the interface. Some codecs refer to the Serial Clock (I2S_SCK) as Baud/Bit Clock (BCLK). Also, the Left/
Right Clock is commonly referred to as LRC or LRCK. The I2S and other audio protocols refer to LRC as Word Select
(WS).
The following codec is supported by default:
• Analog Devices ADAU1961 (24-bit 96KHz)
The I2S interface is assigned to programmable pins (PFx) and therefore the device must be programmed into specific
configurations to enable the interface. Refer to Section 3.3.4, PF[31:3] Configuration (CFG_STRAP[2:1]) for additional
information.
Note:
For I2S timing information, refer to Section 9.6.9, I2S Timing. For detailed information on utilizing the I2S
interface, including support for other codecs, refer to the application note “USB7202/USB725x I2S Opera-
tion”, which can be found on the Microchip USB7016 product page at www.microchip.com/USB7016.
7.3.1
MODES OF OPERATION
The USB audio class operates in three ways: Asynchronous, Synchronous and Adaptive. There are also multiple oper-
ating modes, such as hi-res, streaming, etc.. Typically for USB devices, inputs such as microphones are Asynchronous,
and output devices such as speakers are Adaptive. The hardware is set up to handle all three modes of operation. It is
recommended that the following configuration be used: Asynchronous IN; Adaptive OUT; 48Khz streaming mode; Two
channels: 16 bits per channel.
7.3.1.1
Asynchronous IN 48KHz Streaming
In this mode, the codec sampling clock is set to 48Khz based on the local oscillator. This clock is never changed. The
data from the codec is fed into the input FIFO. Since the sampling clock is asynchronous to the host clock, the amount
of data captured in every USB frame will vary. This issue is left for the host to handle. The input FIFO has two markers,
a low water mark (THRESHOLD_LOW_VAL), and a high water mark (THRESHOLD_HIGH_VAL). There are three reg-
isters to determine how much data to send back in each frame. If the amount of data in the FIFO exceeds the high water
mark, then HI_PKT_SIZE worth of data is sent. If the data is between the high and low water mark, the normal MID_P-
KT_SIZE amount of data is sent. If the data is below the low water mark, LO_PKT_SIZE worth of data is sent.
2021 Microchip Technology Inc.
DS00003740A-page 33
USB7016
7.3.1.2
Adaptive OUT 48KHz Streaming
In this mode, the codec sampling clock is initially set to 48Khz based on the local oscillator. The host data is fed into the
OUT FIFO. The host will send the same amount of data on every frame, i.e. 48KHz of data based on the host clock. The
codec sampling clock is asynchronous to the host clock. This will cause the amount of data in the OUT FIFO to vary. If
the amount of data in the FIFO exceeds the high water mark, then the sampling clock is increased. If the data is between
the high and low water mark, the sampling clock does not change. If the data is below the low water mark, the sampling
clock is decreased.
7.3.1.3
Synchronous Operation
For synchronous operation, the internal clock must be synchronized with the host SOF. The Frame SOF is nominally
1mS. Since there is significant jitter in the SOFs, there is circuitry provided to measure the SOFs over a long period of
time to get a more accurate reading. The calculated host frequency is used to calculate the codec sampling clock.

8.1
Downstream Battery Charging
The device can be configured by an OEM to have any of the downstream ports support battery charging. The hub’s role
in battery charging is to provide acknowledgment to a device’s query as to whether the hub system supports USB battery
charging. The hub silicon does not provide any current or power FETs or any additional circuitry to actually charge the
device. Those components must be provided externally by the OEM.
FIGURE 8-1:
BATTERY CHARGING EXTERNAL POWER SUPPLY
DC Power
Microchip
Hub
VBUS[n]
If the OEM provides an external supply capable of supplying current per the battery charging specification, the hub can
be configured to indicate the presence of such a supply from the device. This indication, via the PRT_CTLx pins, is on
a per port basis. For example, the OEM can configure two ports to support battery charging through high current power
FETs and leave the other two ports as standard USB ports.
The port control signals are assigned to programmable pins (PFx) and therefore the device must be programmed into
specific configurations to enable the signals. Refer to Section 3.3.4, PF[31:3] Configuration (CFG_STRAP[2:1]) for addi-
tional information.
For detailed information on utilizing the battery charging feature, refer to the application note “USB Battery Charging
with Microchip USB70xx Hubs”, which can be found on the Microchip USB7016 product page www.microchip.com/

Port Power Control
Port power and over-current sense share the same pin (PRT_CTLx) for each port. These functions can be controlled
directly from the USB hub, or via the processor.
Note:
Note:
The PRT_CTLx function is assigned to programmable function pins (PFx) via configuration straps. Refer
to Section 3.3.4, PF[31:3] Configuration (CFG_STRAP[2:1]) for additional information.
The port power control for the USB 2.0 and USB 3.2 portions of a specific port can also be individually con-
trolled via the PortSplit function. Refer to Section 8.4, PortSplit for additional information.
8.2.1
PORT POWER CONTROL USING USB POWER SWITCH
When operating in combined mode, the device will have one port power control and over-current sense pin for each
downstream port. When disabling port power, the driver will actively drive a '0'. To avoid unnecessary power dissipation,
the pull-up resistor will be disabled at that time. When port power is enabled, it will disable the output driver and enable
the pull-up resistor, making it an open drain output. If there is an over-current situation, the USB Power Switch will assert
the open drain OCS signal. The Schmidt trigger input will recognize that as a low. The open drain output does not inter-
fere. The over-current sense filter handles the transient conditions such as low voltage while the device is powering up.
Note:
An external power switch is the required implementation for Type-C ports due to the requirement that VBUS
on Type-C ports must be discharged to 0V when no device is attached to the port.

8.2.2
PORT POWER CONTROL USING POLY FUSE
When using the device with a poly fuse, there is no need for an output power control. A single port power control and
over-current sense for each downstream port is still used from the Hub's perspective. When disabling port power, the
driver will actively drive a '0'. This will have no effect as the external diode will isolate pin from the load. When port power
is enabled, it will disable the output driver and enable the pull-up resistor. This means that the pull-up resistor is providing
3.3 volts to the anode of the diode. If there is an over-current situation, the poly fuse will open. This will cause the cath-
ode of the diode to go to 0 volts. The anode of the diode will be at 0.7 volts, and the Schmidt trigger input will register
this as a low resulting in an over-current detection. The open drain output does not interfere.
Note:
Type-C ports may not utilize a Poly-Fuse port power implementation due to the requirements that VBUS
on Type-C ports must be discharged to 0V when no device is attached to the port.

CC Pin Orientation and Detection
The device provides CC1 and CC2 pins on all Type-C ports for cable plug orientation and detection of a USB Type-C
receptacle. The device also integrates a comparator and DAC circuit to implement Type-C attach and detach functions,
which supports up to eight programmable thresholds for attach detection between a UFP and DFP. When operating as
a UFP, the device supports detecting changes in the DFP’s advertised thresholds.
When operating as a DFP, the device implements current sources to advertise current charging capabilities on both CC
pins. By default, the CC pins advertise a 3A VBUS sourcing capability when operating in DFP mode. This may be recon-
figured to 1.5Aor Default USB (500mA for USB2 DFP or 900mAfor a USB3 DFP) via OTP, SMBus, or SPI configuration.
When a UFP connection is established, the current driven across the CC pins creates a voltage across the UFP’s Rd
pull-down that can be detected by the integrated CC comparator. When connected to an active cable, an alternative
pull-down, Ra, appears on the CC pin.
When operating as a UFP, the device applies an Rd pull-down on both CC lines and waits for a DFP connection from
the assertion of VBUS. The CC comparator is used to determine the advertised current charger capabilities supported
by the DFP.
VCONN is a 3V-5V supply used to power circuitry in the USB Type-C plug that is required to implement Electronically
Marked Cables and other VCONN Powered accessories. By default the DFP always sources VCONN when connected
to an active cable. The USB7016 requires the use of two external VCONN FETs. The device provides the enables for
these FETs, and can detect an over-current event (OCS) by monitoring the output voltage of the FET via the CC pins.
2021 Microchip Technology Inc.
DS00003740A-page 37
USB7016
If the voltage on the VCONN line is sensed as <3.0V by the CC comparator of the either CC1 or CC2 (whichever pin is
operating as VCONN at the time) then an over-current event is detected and the VCONN supply is shut off. VCONN is
only sourced on either the CC1 or the CC2 pin, never both. The pin which is to become the VCONN supply is determined
only when a device is attached to the Type-C port. The VCONN supply is controlled from the hub DP1_VCONN1/
DP1_VCONN2/DP2_VCONN2/DP2_VCONN2.
The device also implements a comparator for determining when a VBUS is within a programmed range, vSafe5V or
vSafe0V. VBUS is divided down externally to provide a nominal 2.68V at the VBUS_MON pin. For a DFP, the VBUS
comparator is useful to detect when VBUS is within the required range per power delivery negotiations. For a UFP, the
VBUS comparator is utilized to determine when a DFP is attached or detached. It may also use the comparator to deter-
mine when VBUS is within a new voltage range per power delivery negotiations.
Note:
The native USB Type-C functionality (including CC pin orientation and detection features) is managed
autonomously by the USB7016.
8.4
PortSplit
The PortSplit feature allows the USB 2.0 and USB 3.2 PHYs associated with a downstream port to be operationally sep-
arated. The intention of this feature is to allow a system designer to connect an embedded USB 3.x device to the USB
3.2 PHY, while allowing the USB 2.0 PHY to be used as either a standard USB 2.0 port or with a separate embedded
USB 2.0 device. PortSplit can be configured via OTP/SMBus. By default, all ports are configured to non-split mode.
PortSplit is supported for ports 2, 3, and 4 in configuration 1 and only for port 4 in configuration 2 (refer to Table 3-5).
When PortSplit is disabled on a specific port, the corresponding PRT_CTLx pin controls both the USB 2.0 and USB 3.2
portions of the port (port power and overcurrent condition). When PortSplit is enabled on a specific port, the corre-
sponding PRT_CTLx pin controls the USB 2.0 portion of the port, and the corresponding PRT_CTLx_U3 pin controls
the USB 3.2 portion of the port.
8.5
FlexConnect
The device allows the upstream port to be swapped with any downstream port, enabling any USB port to assume the
role of USB host at any time during hub operation. This host role exchange feature is called FlexConnect. Additionally,
the USB 2.0 ports can be flexed independently of the USB 3.2 ports.
This functionality can be used in two primary ways:
1. Host Swapping: This functionality can be achieved through a hub wherein a host and device can agree to swap
the host/device relationship; The host becomes a device, and the device becomes a host.
2. Host Sharing: A USB ecosystem can be shared between multiple hosts. Note that only 1 host may access to
the USB tree at a time.
FlexConnect can be enabled through any of the following three methods:
• I2C Control: The embedded I2C slave can be used to control the state of the FlexConnect feature through basic
write/read operations.
• USB Command: FlexConnect can be initiated via a special USB command directed to the hub’s internal Hub
Feature Controller device.
• Direct Pin Control: Any available GPIO pin on the hub can be assigned the role of a FlexConnect control pin.
Note:
Direct Pin Control is only available in certain configurations. Refer to Section 3.3.4, PF[31:3] Configuration
(CFG_STRAP[2:1]) for additional information.
For detailed information on utilizing the FlexConnect feature, refer to the application note “USB70xx FlexConnect Oper-
ation”, which can be found on the Microchip USB7016 product page at www.microchip.com/USB7016.

8.10 Resets
The device includes the following chip-level reset sources:
• Power-On Reset (POR)
• External Chip Reset (RESET_N)
• USB Bus Reset
8.10.1
POWER-ON RESET (POR)
A power-on reset occurs whenever power is initially supplied to the device, or if power is removed and reapplied to the
device. A timer within the device will assert the internal reset per the specifications listed in Section 9.6.2, Power-On
and Configuration Strap Timing.
8.10.2
EXTERNAL CHIP RESET (RESET_N)
A valid hardware reset is defined as assertion of RESET_N, after all power supplies are within operating range, per the
specifications in Section 9.6.3, Reset and Configuration Strap Timing. While reset is asserted, the device (and its asso-
ciated external circuitry) enters Standby Mode and consumes minimal current.
Assertion of RESET_N causes the following:
1. The PHY is disabled and the differential pairs will be in a high-impedance state.
2. All transactions immediately terminate; no states are saved.
3. All internal registers return to the default state.
4. The external crystal oscillator is halted.
5. The PLL is halted.
Note:
All power supplies must have reached the operating levels mandated in Section 9.2, Operating Condi-
tions**, prior to (or coincident with) the assertion of RESET_N.
8.10.3
USB BUS RESET
In response to the upstream port signaling a reset to the device, the device performs the following:
1. Sets default address to 0.
2. Sets configuration to Unconfigured.
3. Moves device from suspended to active (if suspended).
4. Complies with the USB Specification for behavior after completion of a reset sequence.
The host then configures the device in accordance with the USB Specification.
Note:
The device does not propagate the upstream USB reset to downstream devices.

SMBus master must allow the bus to remain idle after issuing the “USB Attach with SMBus Runtime Access” until tAT-
TACH_RDY timing has been met.
Note:
When accessing SMBus during runtime, it is critical to force some clocks to stay on. If this step is not taken,
the SMBus slave interface will not be accessible while the hub is placed into a Suspend state by the host.

Clock Specifications
The device can accept either a 25MHz crystal or a 25MHz single-ended clock oscillator input. If the single-ended clock
oscillator method is implemented, XTALO should be left unconnected and XTALI/CLK_IN should be driven with a
nominal 0-3.3V clock signal. The input clock duty cycle is 40% minimum, 50% typical and 60% maximum.
It is recommended that a crystal utilizing matching parallel load capacitors be used for the crystal input/output signals
(XTALI/XTALO). The following circuit design (Figure 9-8) and specifications (Table 9-11) are required to ensure proper
operation.

Note 7: Frequency Deviation Over Time is also referred to as Aging.
Note 8: 0 °C for commercial version, -40 °C for industrial version.
Note 9: +70 °C for commercial version, +85 °C for industrial version.
Note 10: This number includes the pad, the bond wire and the lead frame. PCB capacitance is not included in this
value. The XTALI/CLK_IN pin, XTALO pin and PCB capacitance values are required to accurately calcu-
late the value of the two external load capacitors. These two external load capacitors determine the accu-
racy of the 25.000 MHz frequency.
9.7.2
EXTERNAL REFERENCE CLOCK (CLK_IN)
When using an external reference clock, the following clock characteristics are required:
• 25 MHz
• 50% duty cycle ±10%, ±100 ppm
• Jitter < 100 ps RMS

Note the following details of the code protection feature on Microchip devices:
•
•
•
Microchip products meet the specifications contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is secure when used in the intended manner and under normal conditions.
There are dishonest and possibly illegal methods being used in attempts to breach the code protection features of the Microchip devices. We
believe that these methods require using the Microchip products in a manner outside the operating specifications contained in Microchip's
Data Sheets. Attempts to breach these code protection features, most likely, cannot be accomplished without violating Microchip's intellectual
property rights.
•
•
Microchip is willing to work with any customer who is concerned about the integrity of its code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of its code. Code protection does not mean that we
are guaranteeing the product is "unbreakable." Code protection is constantly evolving. We at Microchip are committed to continuously
improving the code protection features of our products. Attempts to break Microchip's code protection feature may be a violation of the Digital
Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for
relief under that Act.
Information contained in this publication is provided for the sole purpose of designing with and using Microchip products. Information regarding device
applications and the like is provided only for your convenience and may be superseded by updates. It is your responsibility to ensure that your application
meets with your specifications.

WHETHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, STATUTORY OR OTHERWISE, RELATED TO THE INFORMATION INCLUDING BUT
NOT LIMITED TO ANY IMPLIED WARRANTIES OF NON-INFRINGEMENT, MERCHANTABILITY, AND FITNESS FOR A PARTICULAR PURPOSE
OR WARRANTIES RELATED TO ITS CONDITION, QUALITY, OR PERFORMANCE.
IN NO EVENT WILL MICROCHIP BE LIABLE FOR ANY INDIRECT, SPECIAL, PUNITIVE, INCIDENTAL OR CONSEQUENTIAL LOSS, DAMAGE,
COST OR EXPENSE OF ANY KIND WHATSOEVER RELATED TO THE INFORMATION OR ITS USE, HOWEVER CAUSED, EVEN IF MICROCHIP
HAS BEEN ADVISED OF THE POSSIBILITY OR THE DAMAGES ARE FORESEEABLE. TO THE FULLEST EXTENT ALLOWED BY LAW, MICRO-
CHIP'S TOTAL LIABILITY ON ALL CLAIMS IN ANY WAY RELATED TO THE INFORMATION OR ITS USE WILL NOT EXCEED THE AMOUNT OF
FEES, IF ANY, THAT YOU HAVE PAID DIRECTLY TO MICROCHIP FOR THE INFORMATION. Use of Microchip devices in life support and/or safety
applications is entirely at the buyer's risk, and the buyer agrees to defend, indemnify and hold harmless Microchip from any and all damages, claims,
suits, or expenses resulting from such use. No licenses are conveyed, implicitly or otherwise, under any Microchip intellectual property rights unless
