All trade marks are property of their respective holders. June 1998 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. FEATURES • 8-Bit CMOS microcontroller • Up to 50 MHz operation • Additional instructions of memory to memory move with two 16-bit Data Pointers • 256-byte Scratchpad RAM • 12k-byte data memory embedded • 64k-byte address space for external Program Memory • 64k-byte address space for external Data Memory • Three 16-bit timer/counter, the timer0 clock can be programmed • Four 8-bit bidirectional ports • A Seven-source interrupt structure with two priority levels • An additional a programmable watchdog timer • One enhanced programmable full duplex serial port • NEC, PHILIPS and SANYO format remote control receiver • Power-on reset • Built-in power-saving modes - Idle mode & Power-down mode • An additional system Clock Output (W99132E, W99132P) • Operating voltage 4.5V ~ 5.5V • 40-pin DIP package (W99132EX, W99132E) 44-pin PLCC package (W99132P) W99132 Functional Block Following figure shows the function block of W99132 CPU OSC Interupt 12K Bytes SRAM 256 Bytes RAM Serial Port Timer/ Counter I/O Port Bus Expantion Control /INT0, IR /INT1 XTAL2 XTAL1 P0 P1 P2 P3 T0 T1 T2 TXD RXD TIMER0~ TIMER2 UART WATCHDOG TIMER CLKOUT RST /WR /RD ALE /PSEN APPLICATIONS l VCD player l DVD player l Multimedia system The following figure shows a typical VCD player connection diagram of W99132 EEPROM W27E010-70 VCD Controller W99132 DRAM 256kX16-70ns MPEG Decoder W9925QF TV Encoder W9952QP Servo Audio DAC IR UI |
