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.  
FEATURES

· Three 16-bit Timers  
· 12 interrupt sources with two levels of priority  
· On-chip oscillator and clock circuitry  
· Two enhanced full duplex serial ports  
· 256 bytes scratch-pad RAM  
· 1KB on-chip SRAM for MOVX instruction  
· Programmable Watchdog Timer  
· Dual 16-bit Data Pointers  
· Software programmable access cycle to external RAM/peripherals  
· Packages:  
- DIP 40: W77C32-25/40  
- PLCC 44: W77C32P-25/40  
- QFP 44: W77C32F-25/40
