HD404339 Series
Rev. 7.0
Sept. 1999
Description
The HD404339 Series is 4-bit HMCS400-Series microcomputer with large-capacity memory designed to
increase program productivity. Each microcomputer has an A/D converter, input capture timer, and a 32-
kHz oscillator circuit for clock use all built in. They also come with high-voltage I/O pins that can directly
drive a fluorescent display.
The HD404339 Series includes six chips: the HD404339 with 16-kword ROM; the HD4043312 with 12-
kword ROM; the HD404338 with 8-kword ROM; the HD404336 with 6-kword ROM; the HD404334 with
4-kword ROM; the HD4074339 with 16-kword PROM.
The HD4074339 is a PROM version ZTAT™ microcomputer. Programs 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. (The PROM program specifications are the same as for the 27256.)
ZTAT™: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.

I/O
Function
Power supply for the A/D converter. Connect
this pin as close as possible to the V
CC
pin and at
the same voltage as V
CC
. If the power supply
voltage to be used for the A/D converter is not
equal to V
CC
, connect a 0.1-µF bypass capacitor
between the AV
CC
and AV
SS
pins. (However, this
is not necessary when the AV
CC
pin is directly
connected to the V
CC
pin.)
Ground for the A/D converter. Connect this pin
as close as possible to GND at the same voltage
as GND.
