W99132EX / W99132E / W99132P
VCD CONTROLLER
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.
