1. GENERAL DESCRIPTION
The W77L32 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 W77L32 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
W77L32 is a fully static CMOS design; it can also be operated at a lower crystal clock. W77L32
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.
