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 32kHz 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 12kword 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.)
