OTG Connectivity
In OTG mode, FX3 can be configured to be an A, B, or dual-role
device. It can connect to the following:

ReNumeration
Because of FX3's soft configuration, one chip can take on the
identities of multiple distinct USB devices.
When first plugged into USB, FX3 enumerates automatically with
the Cypress Vendor ID (0x04B4) and downloads firmware and
USB descriptors over the USB interface. The downloaded
firmware executes an electrical disconnect and connect. FX3
enumerates again, this time as a device defined by the
downloaded information. This patented two-step process, called
ReNumeration, happens instantly when the device is plugged in.
EZ-Dtect
FX3 supports USB Charger and accessory detection (EZ-Dtect).
The charger detection mechanism complies with the Battery
Charging Specification Revision 1.1. In addition to supporting
this version of the specification, FX3 also provides hardware
support to detect the resistance values on the ID pin.
FX3 can detect the following resistance ranges:

FX3's charger detects a dedicated wall charger, Host/Hub
charger, and Host/Hub.

VBUS Overvoltage Protection
The maximum input voltage on FX3's VBUS pin is 6 V. A charger
can supply up to 9 V on VBUS. In this case, an external
overvoltage protection (OVP) device is required to protect FX3
from damage on VBUS.

Carkit UART Mode
The USB interface supports the Carkit UART mode (UART over
D+/D–) for non-USB serial data transfer. This mode is based on
the CEA-936A specification.
In the Carkit UART mode, the output signaling voltage is 3.3 V.
When configured for the Carkit UART mode, TXD of UART
(output) is mapped to the D– line, and RXD of UART (input) is
mapped to the D+ line.
In the Carkit UART mode, FX3 disables the USB transceiver and
D+ and D– pins serve as pass-through pins to connect to the
UART of the host processor. The Carkit UART signals may be
routed to the GPIF II interface or to GPIO[48] and GPIO[49], as
shown in
In this mode, FX3 supports a rate of up to 9600 bps.
