Preliminary W77C32

8 BIT MICROCONTROLLER

GENERAL DESCRIPTION

The W77C32 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 W77C32 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

W77C32 is a fully static CMOS design; it can also be operated at a lower crystal clock. The W77C32

provides operating voltage from 4.5V to 5.5V. All W77C32 types also support on-chip 1KB 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.
