TIAO USB Multi Protocol Adapter User's Manual

Overview

The TIAO USB Multi Protocol Adapter (TUMPA) is a multi-functional USB communication adapter for hobbyists or engineers. The adapter is based on FDTI's flagship communication chip FT2232H, a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. It has two multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI on two channels simultaneously.

TIAO USB Multi Protocol Adapter Features

  • USB 2.0 Hi-Speed (480Mb/s)
  • JTAG / IEEE 1149.1 compatible.
  • JTAG Baudrate up to 30Mbits/sec (programmable)
  • On board voltage translation via 74LVC14T245 (can be enabled / disabled via software or jumper)
  • JTAG signals are 5V to 1.8V tolerant
  • ARM Muli-ICE 20-pin header compatible.
  • Separate SPI/I2C/Serial interfaces
  • Configurable output of RS232 (MAX3243) or TTL level for serial communication
  • Configurable auto power down for MAX3243
  • Target board can be powered by TUMPA (3.3V) or self powered (via jumper)
