DescriptionThe HD404369 Series is a 4-bit HMCS400-Series microcomputer designed to increase program productivity and also incorporate large-capacity memory. Each microcomputer has an A/D converter, input capture timer, 32-kHz oscillator for clock, and four low-power dissipation modes.
The HD404369 Series includes nine chips: the HD404364, HD40A4364 with 4-kword ROM; the HD404368, HD40A4368 with 8-kword ROM; the HD4043612, HD40A43612 with 12-kword ROM; the HD404369, HD40A4369 with 16-kword ROM; the HD407A4369 with 16-kword PROM.
The HD404369 are high speed versions (minimum instruction cycle time: 0.47 ms).The HD407A4369 is a PROM version (ZTA
TM microcomputer). A program 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 ZTA
TMversion is 27256-compatible.)
