Winbond Electronics W99132P, W99132EX, W99132E Datasheet

GENERAL DESCRIPTION
W99132EX / W99132E / W99132P
VCD CONTROLLER
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.
