Brief Description
The EV8810 Evaluation Kit has been designed for the purpose of evaluating the CMX88x family of
devices. This family includes the CMX881, CMX882 and CMX883 Signalling Processors. The board
interfaces to the parallel port of an IBM compatible PC, running the supplied application software under
Windows 95, 98, ME and NT 4.0 operating systems. The on-board PIC Microcontroller is a Flash device
and can be reprogrammed via the controlling PC with the included programming software. Both the
CMX88x target device and the Flash PIC are socketed, for easy replacement. This evaluation kit is
supplied without any CMX88x target device. Samples of these should be obtained separately from your
local CML distributor.
The on-board audio power amplifier and 3.5mm jack socket can be used to connect an external
loudspeaker, and voice input can be handled via the on-board electret microphone. A user prototyping
area is also included.
The board requires a 5Vdc supply rail for the PIC Microcontroller and another supply rail for the device
voltage, which can range from 2.7Vdc to 5.5Vdc. These can be provided by one dual rail supply or two
single rail supplies.
