The 3802 series of microprocessors is an 8-bit microprocessor based on the 740 family core technology.
The 3802 Group is an 8‑bit CMOS microcomputer based on the 740 family core, designed for control systems that need analog signal processing, serial I/O, A‑D and D‑A converters. It offers configurable memory sizes, multiple I/O ports, timers, and interrupt sources.
The document details pin configurations, electrical characteristics, package types, and expansion options such as mask ROM, OTP and EPROM versions. It also lists part numbering conventions and provides a revision history.
