HD404629R Series

AS Microcomputer Incorporating a DTMF Generator Circuit

ADE-202-048D

Rev.5.0

Sept. 1999

Description

The HD404629R Series is part of the HMCS400-Series microcomputers designed to increase program

productivity and also incorporate large-capacity memory. Each microcomputer has a high precision dual-

tone multifrequency (DTMF) generator, LCD controller/driver, A/D converter, input capture circuit, 32-

kHz oscillator for clock, and four low-power dissipation modes.

The HD404629R Series includes four chips: the HD404628R with 8-kword ROM; the HD4046212R with

12-kword ROM; the HD404629R with 16-kword ROM; the HD4074629 with 16-kword PROM.

A program can be written to the PROM by a PROM writer, which can dramatically shorten system

development periods and smooth the process from debugging to mass production.
