Evaluation Board for
Z86L99 IR Controllers
1 Overview
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
Z86L991
40-pin version
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. It 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.
