W77L516A
1. GENERAL DESCRIPTION
The W77L516A 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 W77L516A 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
W77L516A is a fully static CMOS design; it can also be operated at a lower crystal clock. The
W77L516A contains In-System Programmable (ISP) 64 KB AP Flash EPROM; 4KB LD Flash EPROM
for loader program; operating voltage from 2.7V to 5.5V; on-chip 1 KB MOVX SRAM; two power saving
modes.
2. FEATURES

• Instruction-set compatible with MCS-51
• Four 8-bit I/O Ports; Port 0 has internal pull-up resisters enabled by software
• One extra 4-bit I/O port and Wait State control signal (available on 44-pin PLCC/QFP package)
• Three 16-bit Timers
• 12 interrupt sources with two levels of priority
• On-chip oscillator and clock circuitry
• Two enhanced full duplex serial ports
• 64KB In-System Programmable Flash EPROM(APFLASH)
• 4KB Auxiliary Flash EPROM for loader program (LDFLASH)
• 256 bytes scratch-pad RAM
• 1 KB on-chip SRAM for MOVX instruction
• Programmable Watchdog Timer
• Software Reset
• Dual 16-bit Data Pointers
• Software programmable access cycle to external RAM/peripherals
• Packages:
