M37221EASP - Single-Chip 8-Bit CMOS Microcomputer

Download the M37221EASP datasheet PDF. This datasheet also covers the M37221M8H variant, as both devices belong to the same single-chip 8-bit cmos microcomputer family and are provided as variant models within a single manufacturer datasheet.

General 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.
