1 Product Description
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.
The JTAG Chain of the connected hardware module which is useful to program and debug onboard devices
can be accessed in two different ways: If it is accessed via the 14-pin Header, which must be the case when
communicating with Xilinx Devices, a "Xilinx Platform Cable USB II" (which is required) can be connected
without any adaption. If the JTAG Chain is accessed via the USB interface, Channel A of the USB Controller
is not used to communicate with Interface A, but to generate JTAG signals for debugging or programming
reasons. In this configuration, Lattice Devices for example can directly be programmed without the necessity
of an additional Programming Cable, as the TA900 is directly supported by Lattice's Software Tool "ispVM".
The TA900 is self-powered by the FPC Connector which means that it is not necessary to connect the
Interface Box to USB to provide a supply voltage. The Interface Box meets the requirements to operate in
extended temperature range from -30° to +75°C and comes with a USB A to USB B Cable and an FPC
Flexcable.

3 Configuration
To modify the LED Configuration and the JTAG Configuration remove the PCB Compartment
Door and set the DIP Switches and the Rotary Selector Switch accordingly.
3.1 JTAG Configuration
The JTAG Chain of the connected hardware module which is useful to program and debug onboard devices
can be accessed in two different ways:
If it is accessed via the 14-pin Header, which must be the case when communicating with Xilinx Devices, a
"Xilinx Platform Cable USB II" (which is required) can be connected without any adaption.
If the JTAG Chain is accessed via the USB interface, Channel A of the USB Controller is not used to
communicate with Interface A, but to generate JTAG signals for debugging or programming reasons. In this
configuration, Lattice Devices for example can directly be programmed without the necessity of an additional
Programming Cable, as the TA900 is directly supported by Lattice's Software Tool "ispVM".
Whether the JTAG Chain of the module connected to the FPC Connector is accessed by the JTAG Header
or by USB is determined by the configuration of the Rotary Selector Switch:
Position Function
0 The JTAG Chain can be accessed via JTAG Header
1 The JTAG Chain can be accessed via JTAG Header [default]
2
Software Controlled:
o Outputting HIGH level at GPIOH7 Pin when Interface A is configured to
MPSSE-Mode enables JTAG over USB.
o Outputting LOW level enables JTAG over JTAG Header
The JTAG Chain can be accessed via USB-Controller if Interface A is configured to
MPSSE-Mode

3.2 LED Configuration
The yellow LEDs for Interface A and Interface B in the TA900 Front Panel can be configured to operate in
two different ways by setting DIP Switches:
o Set to Logic, the LEDs indicate the logic level of the corresponding interface pins.
o Set to UART, they indicate UART traffic on the Rx Line and Tx Line of the corresponding interface. [default]
4 Drivers
FTDI provides Virtual COM Port (VCP) drivers which cause the USB device to appear as two additional COM
ports available on the PC. These COM ports can be accessed like standard COM ports by the operating
system. The following operating systems are supported:
x Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008,
Windows 7, Windows Server 2008 R2 (32-bit and 64-bit)

x Windows CE 6.0 (32-bit, ARM, MIPSII, MIPSIV, SH4)
Additionally, FTDI provides D2XX drivers which allow direct access to the USB device through a DLL. This
offers the user to design application software which can access the USB device through a series of DLL
function calls. The project FTCJTAG DLL can be downloaded at the FTDI homepage to handle all Multi-
Protocol Synchronous Serial Engine (MPSSE) commands necessary to create a USB to JTAG interface. The
