Preliminary W77E58

GENERAL DESCRIPTION

The W77E58 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 W77E58 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

W77E58 is a fully static CMOS design; it can also be operated at a lower crystal clock. The W77E58

contains 32 KB flash Multiple-Time Programmable(MTP) ROM, and provides operating voltage from

4.5V to 5.5V. All W77E58 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.
