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.
