The S3F80QB MCU, a member of Zilog's S3F8 Series of S3 MCUs, offers a fast and efficient Z8-compatible CPU, 63 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 128-byte sector size.

This device features an LVD circuit and up to 38 bit-programmable pins, 4 timer/counters, one basic timer, includes 24 interrupt sources with 18 vectors, and can recognize up to 9 interrupt levels. As such, the S3F80QB MCU is designed specifically for universal remote control applications.

The S3F80QB MCU is offered in the following 3 package types:

• 44-pin ELP

• 44-pin QFP

• Pellet (Die)
