Product Overview

FT4233HP is a hi-speed USB device with a Type-C/PD3.0 controller that fully supports the latest USB Type-C and Power Delivery (PD) standards enabling support for power negotiation with the ability to sink or source current to a USB host device. The USB bridge function delivers 4 independent channels compatible with the existing FT4232H quad hi-speed USB to multipurpose UART/MPSSE solution. Port 1 mode configuration for sink or dual-role. Port 2 works as sink, supporting charge through to port 1. Supports 5V3A, 9V3A, 12V3A, 15V3A and 20V3A PDOs as sink or source. PD policy engine using 32bit RISC controller with 8KB data RAM and 48KB code ROM. PD mode configuration through external EEPROM. USB 2.0 high speed (480Mbits/second) and full speed (12Mbits/second) compatible. Two multi-protocol synchronous serial engine (MPSSE) on channel A and channel B, to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.
  • Supports the PD specification Rev 3.0
  • Type-C/PD physical layer protocol
  • Options to use external MCU controlling PD policy through 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
  • Extended -40°C to 85°C industrial operating temperature rang
  • 3.3V single supply operating voltage range, +3.3V I/O interfacing
  • Dedicated Windows/Linux DLLs available for USB to SPI, and USB to I2C applications
  • USB bulk data transfer mode (512 byte packets in high speed mode)
  • Configurable I/O drive strength (4, 8, 12 or 16mA) and slew rate
