Dual/Quad High-Speed USB to UART/FIFO IC


The FT2232H and FT4232H are FTDI's fifth generation of USB devices

The FT2232H (Dual) and FT4232H (Quad) are FTDI’s 5th generation of USB devices. The FT2232H and FT4232H are USB 2.0 high-speed (480 Mb/s) to UART/MPSSE ICs. The device features 2 or 4 UARTs respectively. They have the capability of being configured in a variety of industry-standard serial or parallel interfaces.

The FT4232H can have two independent UART’s that can configure an MPSSE engine. This allows the FT4232H to operate as two UART/bit-bang ports plus two MPSSE engines used to emulate JTAG, SPI, I2C, bit-bang or other synchronous serial modes.

Features
  • Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI, or bit-bang) design
  • RS232/RS422/RS485 UART transfer data rate up to 12 Mbaud. (RS232 data rate limited by external level shifter)
  • Low-operating and USB-suspend current
  • Single-chip USB to serial / parallel ports with a variety of configurations
  • Extended -40°C to 85°C industrial operating temperature range
  • +1.8 V (chip core) and +3.3 V I/O interfacing (+5 V tolerant)
  • +3.3 V single-supply operating voltage range
  • Compact 64-LD lead-free LQFP or QFN package
  • Configurable I/O drive strength (4, 8, 12 or 16 mA) and slew rate
  • Supports bus-powered, self-powered, and high-power bus-powered USB configurations
