The 80C562/83C562 is a single-chip 8-bit microcontroller manufactured by Philips Semiconductors. It has 8-bit A/D, capture/compare timer, high-speed outputs, PWM and other functions.
The 80C562/83C562 is a single‑chip 8‑bit microcontroller compatible with the 80C51 instruction set. It integrates 8 kB of ROM, 256 B of RAM, an 8‑bit ADC, PWM outputs, two standard 16‑bit timers, an additional 16‑bit timer, a full‑duplex UART, and a watchdog timer, all in an advanced CMOS process.
The document details ordering information, pin assignments, oscillator and reset requirements, power‑down and idle modes, absolute maximum ratings, and DC electrical characteristics. It also includes analog input specifications and performance notes for designers.
| ROM size | 8 k × 8 bits, expandable to 64 kB |
|---|---|
| RAM size | 256 × 8 bits, expandable to 64 kB |
| ADC | 8‑bit ADC with eight multiplexed analog inputs |
