HD404652H Datasheet 4-bit Single-chip Microcomputer

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD404654 Series 4-Bit Single-Chip Microputer Rev. 7.0 Sept. 1999.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The HD404654 Series is a member of the HMCS400-series of microputers designed to increase program productivity with large-capacity memory.

Each microputer has a high-precision dual-tone multi-frequency (DTMF) generator, three timers, serial interface, voltage parator, and input capture circuit.

The HD404654 Series includes three chips: the HD404652 with 2 k-word ROM;
