HD404618 Series
4-Bit Single-Chip Microcomputer
Rev. 6.0
Sept. 1998
Description
The HD404618 Series is designed with the powerful and efficient architecture of the HMCS400 family.
The MCU incorporates a high-precision dual-tone multifrequency (DTMF) circuit, LCD driver/controller,
voltage comparator, and 32-kHz watch oscillator circuit.
The HD404618 Series includes five chips: the HD404612 with 2-kword ROM; the HD404614 with 4-
kword ROM; the HD404616 with 6-kword ROM; the HD404618 with 8-kword ROM; the HD4074618
with 8-kword PROM.
The HD4074618, incorporating PROM, is a ZTAT™ microcomputer that can dramatically shorten system
development periods and smooth the process from debugging to mass production.
ZTAT™ : Zero Turn Around time ZTAT is a trademark of Hitachi Ltd.
