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
TM
microcomputer that can dramatically shorten system
development periods and smooth the process from debugging to mass production.
ZTATTM : Zero Turn Around time ZTAT is a trademark of Hitachi Ltd.

Pin Functions
Power Supply
V
CC
: Apply power voltage to this pin.
GND: Connect to ground.
TEST: Used for test purposes only. Connect it to V
CC
.
RESET: Resets the MCU.
Oscillators
OSC
1
, OSC
2
: Used as pins for the internal oscillator circuit. They can be connected to a ceramic
resonator, or OSC
1
can be connected to an external oscillator circuit.
X1, X2: Used for a 32.768-kHz crystal oscillator that acts as a clock.
Ports

13
(D Port): Input/output port addressable by individual bits. D
0
D
9
are I/O pins and D
10
D
13
are
input pins. D
0
D
9
are high current output pins (15 mA, max.). D
