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 ModuleManagement 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.
