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.

Technical Specifications

  • 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)
  • 4 on-board LEDs / PWR, Targt PWR, TX and RX
  • 1 2x10 20 PIN JTAG header
  • 1 2x5 10 PIN RS232 level 2.54mm IDC header
  • 1 2x6 10 PIN TTL level 2.54mm IDC header
  • 2 2x3 6 PIN SPI 2.54mm IDC header
  • 1 x DB9 connector (male, RS232 level)
  • Target board power jumper
  • Buffer chip enable jumper
  • RS232 chip auto power down jumper
  • RS232 or TTL output jumber
  • USB Hot-Plug / JTAG Hot-Plug.
  • USB over-current protection via on-board resetable fuse.
  • Strong ESD protection on USB signals.
  • Based on the FTDI FT2232H USB device.
  • Designed for FTDI MPSSE easy-to-use.
  • Free drivers for Linux.
  • Free drivers for Windows XP, Windows Vista and Windows 7
  • Support both 32 bit and 64 bit operating systems
  • Board dimension: 65.41mm X 58.55mm (2.58" X 2.31")

Board Layout

  1. DB9 male RS232 connector (Channel B)
  2. 2x3 standard 6 PIN 2.54mm IDC SPI connector (Channel A)
  3. 2x10 standard 20 PIN 2.54mm IDC JTAG connector (Channel A)
  4. Auto power down jumper header for MAX3243 (force on or auto power down). Default force on (jumper is on pin 1and 2)
  5. Buffer enable jumper header for 74LVC16T245. Default is always enabled. (jumper on pin 2 and 3)
  6. Target voltage select jumper. Default is to power target board by TUMPA (3.3V only) (jumper on pin 1 and 2)
  7. 3x8 PIN RS232 or TTL level serial communication jumpmer. Default is RS232 output (jumpers short rowtop and middle rows) (Channel B)
  8. 2x6 PIN TTL level 2.54mm IDC serial header (channel B)
  9. 2x3 PIN 2.54mm IDC SPI header (channel B)
  10. Target board power LED. Indicates target board has power.
  11. Status LEDs. From left to right: Power (indicates TUMPA is powered on), RX and TX.
