Overview

The S3F80P5 MCU, a member of Zilog’s S3F8 Series of S3 MCUs, offers a fast and efficient Z8-compatible CPU, 18 KB of Flash memory, and a wide range of integrated peripherals.

The S3 Family CPU features an efficient register-oriented architecture and a sophisticated interrupt controller that allow for fast context switching. Flash memory is CPU-programmable and offers a 144-byte sector size.

This device features 19 bit-programmable pins, 3 timer/counters, one basic timer, includes 17 interrupt sources with 14 vectors, and can recognize up to 8 interrupt levels. As such, the S3F80P5 MCU is designed specifically for multi-function remote control applications.

The S3F80P5 MCU is offered in the following 3 package types:

• 24-pin ELP
• 24-pin SOP
• Pellet (Die)
