W79E632A/W79L632A
1. GENERAL DESCRIPTION
The W79E(L)632 is a fast 8051 compatible microcontroller with a redesigned processor core without
wasted clock and memory cycles. Typically, the instruction executing time of W79E(L)632 is 1.5 to 3
times faster than that of traditional 8051, depending on the type of instruction. In general, the overall
performance is about 2.5 times better than the original for the same crystal speed. Consequently, the
W79E(L)632 is a fully static CMOS design; it can also be operated at a lower crystal clock.
The W79E(L)632 contains In-System Programmable (ISP) 128 KB bank-addressed Flash EPROM; 4KB
auxiliary Flash EPROM for loader program; on-chip 1 KB MOVX SRAM; 6-ch PWM outputs; power
saving modes. This product is proper to used in plate display application with cost effectiveness.
Note: If the applied VDD is not stable, especially with long transition time of power on/off, it’s
recommended to apply an external RESET IC to the RST pin for improving the stability of system.
2. FEATURES
8-bit CMOS microcontroller
High speed architecture of 4 clocks/machine cycle
Pin and instruction-set compatible with standard 80C52
Dual 64KB In-System Programmable Flash EPROM banks (APFlash0 and APFlash1)
4KB Auxiliary Flash EPROM for loader program (LDFlash)
256 bytes scratch-pad RAM
1 KB on-chip SRAM for MOVX instruction
Four 8-bit I/O Ports; Port 0 has internal pull-up resisters enabled by software
Three 16-bit Timers
7 interrupt sources with two levels of priority
On-chip oscillator and clock circuitry
One enhanced full duplex serial port
One extra 4-bit I/O port, chip select
Programmable Watchdog Timer
6 channels of 8 bit PWM
Software Reset
Software programmable access cycle to external RAM/peripherals
Code protection
