Signals, Interfaces and Pins
2x5 Female Socket
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).

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).
On-board LEDs
The onOn-board LEDs indicates system status data transmission activitiesindicating power-on and user dependent:
