Description
The SC8735S is a high-performance static 80C51 design fabricated with Philips high-density CMOS technology. It operates from 2.7V to 5.5V and features a 4k × 8 ROM, a 128 × 8 RAM, 32 I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits.
