Revision A10
1. GENERAL DESCRIPTION
The W77E058 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 W77E058 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
W77E058 is a fully static CMOS design; it can also be operated at a lower crystal clock. The
W77E058 contains 32 KB Flash EPROM, and provides operating voltage from 4.5V to 5.5V. All
W77E058 types also support on-chip 1 KB SRAM without external memory component and glue logic,
saving more I/O pins for users’ application usage if they use on-chip SRAM instead of external SRAM.
