Preliminary W77IC32
8 BIT MICROCONTROLLER
Publication Release Date: March 2000
- 1 - Revision A0
GENERAL DESCRIPTION
The W77IC32 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 W77IC32 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
W77IC32 is a fully static CMOS design; it can also be operated at a lower crystal clock. W77IC32
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.
