Description

The HD404358 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, and two low-power dissipation modes.

The HD404358 Series includes seven chips: the HD404354, HD40A4354 with 4-kword ROM; the HD404356, HD40A4356 with 6-kword ROM; the HD404358, HD40A4358 with 8-kword ROM; the HD407A4359 with 16-kword PROM.The HD40A4354, HD40A4356, HA40A4358, and HD407A4359 are high speed versions (minimum instruction cycle time: 0.47 ms)

TheHD404358 is a PROM version (ZTA^TMmicrocomputer). 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^TM version is 27256-compatible.)ZTA^TM: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.
