HD404054 Series/HD404094 Series

Rev. 6.0

Sept. 1998

Description

The HD404054 Series and HD404094 Series are HMCS400-series microcomputers designed to increase

program productivity with large-capacity memory. Each microcomputer has three timers, one serial

interface, comparator, input capture circuit.

The HD404054 Series includes three chips: the HD404052 with 2-kword ROM; the HD404054 with 4-

kword ROM; and the HD4074054 with 4-kword PROM (ZTAT version). Also, the HD404094 Series

includes three chips: the HD404092 with 2-kword ROM; the HD404094 with 4-kword ROM; and the

HD4074094 with 4-kword PROM (ZTAT version).

The HD4074054 and HD4074094 are PROM version (ZTAT microcomputers). 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 ZTAT version is 27256-compatible.)
