0 Sept.
1998 Description The HD404318 Series is 4-bit HMCS400-series microcomputer with large-capacity memory designed to increase program productivity.
Each microcomputer has an A/D converter and input capture timer built in.
They also come with high-voltage I/O pins that can directly drive a fluorescent display.
The HD404318 Series includes four chips: the HD404318 with 8-kword ROM; the HD404316 with 6kword ROM; the HD404314 with 4-kword ROM; the HD4074318 with 8-kword PROM.
The HD4074318 is a PROM version ZTAT™ microcomputer.
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.
