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.)
