HD404318 Series Rev. 6.0 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.
