M37221EASP - Single-Chip 8-Bit CMOS Microcomputer

This page provides the datasheet information for the M37221EASP, a member of the M37221M8H Single-Chip 8-Bit CMOS Microcomputer family.

Description

The M37221M4H/M6H/M8H/MAH-XXXSP/FP are single-chip microcomputers designed with CMOS silicon gate technology.

They have a OSD, I2C-BUS interface, and PWM, making them perfect for TV channel selection system.

The M37221EASP/FP have a built-in PROM that can be written electrically.
