GENERAL DESCRIPTION

The W99132 is a VCD microcontroller with

standard 80C32 core. It contains embedded

12KB SRAM without external memory anymore.

It provides improved peripheral function as to

communicate

with

other

components

conveniently. And a porgrammable Watchdog

Timer is dedicated to supervising the system. It

also support Remote Control Receiver to sense

user command more rapidly and correctly.

Additional direct block move operation with

auto-increment on source or destination address

provide an efficient data move ability.
