FTDI has launched the FT4233HP, a high-speed USB bridge with a controller IC that fully supports USB Type-C® and power delivery (PD) standards. This enables the device to support power negotiation with the ability to sink or source current to a USB host device. The USB bridge function delivers four independent channels that are compatible with the FT4232H quad high-speed USB to multipurpose UART/MPSSE solution. The FT4233HP is ideal for applications such as USB-to-UART cables, USB docking stations, USB solid-state disks, and USB interface modules.
Supports the PD specification Rev 3.0
Port 1 mode configuration for sink or dual-role
Port 2 works as a sink supporting charge through to port 1
Support 5 V, 3 A; 9 V, 3 A; 12 V, 3 A; 15 V, 3 A; and 20 V, 3 A PDOs as a sink or source
Type-C/PD physical layer protocol
PD policy engine using a 32-bit RISC controller with 8 kB data RAM and 48 kB code ROM
PD mode configuration through external EEPROM
Options to use an external MCU controlling PD policy through the I2C interface
USB to quad serial ports with a variety of configurations
Entire USB protocol handled on the chip (no USB specific firmware programming required)
USB 2.0 high-speed (480 Mb/s) and full-speed (12 Mb/s) compatible
Independent Baud rate generators
RS232/RS422/RS485 UART transfer data rate up to 12M baud (RS232 data rate limited by an external level shifter)
FTDI’s royalty-free virtual com port (VCP) and direct (D2XX) drivers eliminate the requirement for USB driver development in most cases
Two multi-protocol synchronous serial engines (MPSSE) on channel A and channel B:
Simplify synchronous serial protocol (USB to JTAG, I2C, SPI, or bit-bang) design
USB bridge with Type-C/PD 3.0 (chargers and devices)
High power consumption via USB PD and/or Type-C port
Get power from USB device functions (portable USB host needs charging when the USB is connected)
