Overview
The TIAO USB Multi Protocol Adapter Lite (TUMPA Lite) is a multi-functional USB communication adapter for hobbyists or engineers. The adapter is based on FDTI's flagship communication chip FT232H, a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. It has one multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI.
The driver of TUMPA Lite can be downloaded from here
Technical Specifications
- Single channel USB to serial / parallel ports with a variety of configurations.
- Entire USB protocol handled on the chip. No USB specific firmware programming required.
- USB 2.0 Hi-Speed (480Mbits/Second) and Full Speed (12Mbits/Second) compatible.
- Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.
- UART transfer data rate up to 12Mbaud. (RS232 Data Rate limited by external level shifter).
- USB to asynchronous 245 FIFO mode for transfer data rate up to 8 MByte/Sec.
- USB to synchronous 245 parallel FIFO mode for transfers up to 40 Mbytes/Sec
- Supports a half duplex FT1248 interface with a configurable width, bi-directional data bus (1, 2, 4 or 8 bits wide).
- CPU-style FIFO interface mode simplifies CPU interface design.
- Fast serial interface option.
- FTDI's royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.
- Adjustable receive buffer timeout.
- Option for transmit and receive LED drive signals.
- Bit-bang Mode interface option with RD# and WR strobes
- Highly integrated design includes 5V to 3.3/+1.8V LDO regulator for VCORE, integrated POR function
- Asynchronous serial UART interface option with full hardware handshaking and modem interface signals.
- Fully assisted hardware or X-On / X-Off software handshaking.
- UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity.
- Auto-transmit enable control for RS485 serial applications using TXDEN pin.
- Operation configuration mode and USB Description strings configurable in external EEPROM over the USB interface.

Connector Pinout & LEDs
- RX: Indicates FT232H is receiving bytes from target via serial communication channel. See 2x3 standard 6 PIN 2.54mm IDC for RX/TX LED on how to enable this.
- TX: Indicates FT232H is transmitting bytes to target via serial communication channel. See 2x3 standard 6 PIN 2.54mm IDC for RX/TX LED on how to enable this.
- PWR: Indicates the TUMPA Lite board is connected to USB port of the computer and FT232H's onboard voltage regulator outputs +3.3V.
- V3.3 Out: Indicates the TUMPA Lite's onboard voltage LDO outputs +3.3V.
RX TX LED Config Header
This jumper header enables LED output on RX and TX.
AC8 is configured the RX led output pin, AC9 is configured the TX led output pin.
Install a jumper on pin 1 and 3 enables RX LED. Install a jumper on pin 2 and 4 enables TX LED.
If AC8 and AC9 are configured for GPIO, you need to remove jumpers on this header.
