8-bit MCU Series (80C51-based)

Part No.	W79E632A
Datasheet	W79E632A_W79L632A.pdf
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.
