2 / 20 page Philips Semiconductors Product specification 80C562/83C562 Single-chip 8-bit microcontroller Single-chip 8-bit microcontroller with 8-bit A/D, capture/compare timer, high-speed outputs, PWM 2 1992 Jan 08 853–1463 05128 DESCRIPTION The 80C562/83C562 (hereafter generically referred to as 8XC562) Single-Chip 8-Bit Microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 83C562/83C562 has the same instruction set as the 80C51. The 8XC562 contains a non-volatile 256 × 8 read-only program memory, a volatile 256 × 8 read/write data memory (83C562) (the 80C562 is ROMless), a volatile 256 × 8 read/write data memory, six 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the 80C51), an additional 16-bit timer coupled to capture and compare latches, a 15-source, two-priority-level, nested interrupt structure, an 8-input ADC, two pulse width modulated outputs, standard 80C51 UART, a “watchdog” timer and on-chip oscillator and timing circuits. For systems that require extra capability, the 83C562 can be expanded using standard TTL compatible memories and logic. The device also functions as an arithmetic processor having facilities for both binary and BCD arithmetic plus bit-handling capabilities. The instruction set consists of over 100 instructions: 49 one-byte, 45 two-byte and 17 three-byte. With a 12MHz crystal, 58% of the instructions are executed in 1 µs and 40% in 2 µs. Multiply and divide instructions require 4 µs.
