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.
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.
- Configurable I/O drives strength (4, 8, 12 or 16mA) and slew rate.
- Low operating and USB suspend current.
- Supports self powered, bus powered and high-power bus powered USB configurations.
- UHCI/OHCI/EHCI host controller compatible.#
- USB Bulk data transfer mode (512 byte packets in Hi-Speed mode).
- +1.8V (chip core) and +3.3V I/O interfacing (+5V Tolerant).
- Extended -40°C to 85°C industrial operating temperature range.

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.
With FT232H's default configuration, AC8 is the RX led output pin, AC9 is 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.
