Overview

https://wiki.trenz-electronic.de/display/PD/TEI0004+TRM for the current online version of this manual and other available documentation.

The Trenz Electronic TEI0004 is an universal USB2.0 adapter board based on the FTDI FT2232H USB2.0 IC. The adapter board converts signals from USB2.0 to the standard serial interfaces JTAG and UART.

The board is fully compatible to USB Blaster to program Intel (Altera) FPGA devices.

Key Features

Supported by Intel Quartus, Intel JTAG Compatible Pinout
Additional UART Channel available
Based on FTDI FT2232H USB2 Interface
Micro USB Connector
RED activity LED
GREEN Power-on LED

Signals, Interfaces and Pins

JTAG Connector Pinout

The 2x5 female socket have to be connected to the corresponding pin header on the target system. The signal assignment of the pin header on the adapter board is fully compatible to original USB blaster. Furthermore there is also an UART interface available and user configurable I/O pin (usable e.g. as Reset signal).

Following table describes the pin-assignment to the signals of the interfaces:

Signal	Pin Number	Pin Number	Signal
TCK	1	2	GND
TDO	3	4	Reference I/O-voltage of target board
TMS	5	6	User
UART RX	7	8	UART TX
TDI	9	10	GND

Table 1: 2x5-pin female socket pin-assignment.

USB Interface

The USB2.0 interface is provided by the FTDI FT2232H chip accessible by the Micro USB2.0 B (receptacle) socket. The entire USB protocol is handled on chip and compatible to USB2.0 High Speed (480 MBps) and Full Speed (12 MBps).

On-board Peripherals

FTDI FT2232H IC

The FTDI FT2232H chip provides a variety of industry standard serial or parallel interfaces. On the TEI0004 adapter board the interfaces USB2.0 to JTAG, UART and one user GPIO are available.

Refer to the FTDI data sheet to get information about the capacity of the FT2232H IC.

Configuration EEPROM

The external EEPROM can be used to customize the TEI0004 adapter board by setting numerous parameters of the FT2232H IC, enabling different functionalities and configuring serial or parallel interfaces.

The EEPROM is programmable in-circuit over USB using a utility program called FT_PROG available from FTDI’s web site (www.ftdichip.com).
