Z86L9900100ZC0

The Z86L9900100ZCO is the evaluation board for ZiLOG's new Z86L99 family of cost-effective IR microcontrollers. Z86L990 microcontrollers have three counter/timers, a 4 channel analog to digital converter, a constant current source, flexible input/output pins with flexible Stop Mode Recovery wake up sources. The Z86L99 microcontroller can be used to interface with a Varatouch pointing device sensor directly and can communicate with an IBM PC through PS2 connections. The Z86L9900100ZCO evaluation board provides left and right buttons on the mouse and supports full PS2 mouse implementation with the Varapoint sensor. The Z86L9900100ZCO evaluation board supports two pinouts:
Z86L990 40-pin version
Z86L991 28-pin version
The Z86L9900100ZCO evaluation board also supports infrared wireless keyboard development. It has all 104 Windows 95 keys plus 28 keys reserved for the universal remote control function. The evaluation board comes with sample code to control standard IR keyboards.

The on-board infrared demodulator on the evaluation board is connected to the timer demodulation input. Z86L9900100ZCO provides a means for reception for the learning remote and two way infrared communication features.The IR LED is directly driven by P43, the 100 mA controlled current output,reducing system cost for the amplification circuit.
