Description

The board features both a 32-pin Host Port Interface as well as a 34-pin Host Port Interface; only one interface can be active at a time. It has an integrated JTAG emulator, but can be used with an external JTAG emulator as well. The ZSP 403US initialization is possible only through the HPI port; after power on reset, the on board micro-controller bootstraps the 403US through the host port with the Software Monitor code allowing the JTAG emulator to control the ZSP. The board is 6.4 inches by 4 inches in size and designed around the ZSP 403US chip (144-pin LBGA). The evaluation board has 4 individual LEDs controlled via PIO, which can be used for status information or debugging. An integrated USB controller with 8-bit HPI interface is on board, making it possible to load programs and start/stop the ZSP 403US by simply plugging a USB cable into the board.

The board may be powered via the USB port if the power draw is less than 300mA. The micro-controller controls the power supply voltage level and measures the current supplied to the ZSP. The board has an integrated 16-bit stereo codec which is disabled when any adapter board is plugged into SPORT0.

This versatile evaluation board can be integrated with additional hardware from Domain Technologies to support telephony testing. Create a 2 or 4 line VOIP demo system by adding one or more DTSLIC2L telephony daughter boards.
