HD404369 Series

Rev. 6.0

Sept. 1998

Description

The 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 HD40A4364, HD40A4368, HD40A43612, HD40A4369, and HD407A4369 are high speed versions

(minimum instruction cycle time: 0.47

µs).

The HD407A4369 is a PROM version (ZTAT

™ 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 ZTAT

™ version is 27256-compatible.)
