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.
