Description

The HD404344R series and HD404394 series 4-bit microcomputers are products of the HMCS400 series, which is designed to make application systems compact while realizing higher performance and increasing program productivity.

Each HD404344R series and HD404394 series microcomputer has an A/D converter, two timers and a serial interface. The HD404344R series includes the HD404344R with on-chip 4-kword ROM, HD404342R with 2-kword ROM, and HD404341R with 1-kword ROM. The HD404394 series includes the HD404394 with on-chip 4-kword ROM, HD404392 with 2-kword ROM, and HD404391 with 1-kword ROM.

The HD404344R series and HD404394 series are the PROM version ZTATTM microcomputers. 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.) ZTATTM: Zero Turn Around Time ZTAT is a Trademark of Hitachi Ltd.
