Preliminary W77E516
Publication Release Date: August 16, 2002

Revision A1
1. GENERAL DESCRIPTION
The W77E516 is a fast 8051 compatible microcontroller with a redesigned processor core without
wasted clock and memory cycles. As a result, it executes every 8051 instruction faster than the original
8051 for the same crystal speed. Typically, the instruction executing time of W77E516 is 1.5 to 3 times
faster then 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. Giving the same
throughput with lower clock speed, power consumption has been improved. Consequently, the
W77E516 is a fully static CMOS design; it can also be operated at a lower crystal clock. The W77E516
contains In-System Programmable (ISP) 64 KB Flash EPROM; 4KB auxiliary Flash EPROM for loader
program; operating voltage from 4.5V to 5.5V; on-chip 1 KB MOVX SRAM; three power saving modes.
