The
DT403LP board is 6.4 inches by 4 inches in size and designed around the ZSP
403LP chip (208-pin PQFP). It has
an integrated JTAG emulator, but can be used with an external JTAG emulator. The
evaluation board has 8 individual LEDs which can be used for status information
or debugging; 4 are controlled via PIO and 4 controlled via EMI and PLD. An
integrated USB controller with 8-bit HPI interface is on board, making it
possible to load programs and start/stop the ZSP 403LP by simply plugging a USB
cable into the board. The board
has an integrated 16-bit stereo codec which is disabled when any adapter board
is plugged into SPORT0. It
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.

The
ZSP 403LP initialization is possible only through the HPI port. After
power on reset, the on board micro-controller bootstraps the ZSP 403LP through
the host port with the Software Monitor code allowing the JTAG emulator to
control the ZSP. The board may be
powered via the USB port if the power draw is less than 300mA.
This versatile evaluation board can be integrated with additional
hardware from Domain to support telephony testing. Create a 2 or 4 line
VOIP demo system by adding one or more
DTSLIC2L telephony daughter boards.
