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.
