TA900

Program and Debug Box

Application Information

The TA900 is an Interface Box which can be used to

program and debug hardware modules providing a

corresponding connector.

The Interface Box connects to compatible modules via a

20-pin Flexible Printed Circuit (FPC) Connector which

can provide access to the module's JTAG Chain and the

additional interfaces A and B.

The TA900 can be accessed by USB 2.0 and by a 14-pin

JTAG Header, and is equipped with a Pushbutton Switch

which is offering the possibility to send an impulse to one

of the connected module's I/O pins.

A green LED indicates the assertion of this impulse by

interrupting illumination.

In case of the user programmable FPGA boards

TAMC631 and TAMC640/641, Interface A provides

access

to

the

UART

of

the

onboard

Module

Management Controller (MMC), and Interface B connects

to two user pins of the module's onboard FPGA. If a

UART core is implemented in the module's FPGA, serial

communication via Interface B is possible.

By setting DIP Switches, the provided yellow LEDs

located in the TA900 front panel can either indicate the

logic level of the Interface's lines or can be configured to

visualize serial communication on the Rx and Tx lines, if

they are connected to the UART interfaces of the USB

Controller.

Level Shifters can handle I/O voltages between 1.2V and

3.3V at the FPC Connector which offers a wide range of

possible configurations for Interface A, B and the JTAG

Chain of the connected hardware module.
