HD404344R Series/HD404394 Series
Rev. 7.0
Sept. 1999
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 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 HD4074344 and HD4074394 are the PROM version ZTATmicrocomputers. 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.)
ZTAT: Zero Turn Around Time ZTAT is a Trademark of Hitachi Ltd.
