HD404459 Series
Rev. 6.0
Sept. 1998
mDescription
.coThe HD404459 Series is a member of the 4-bit HMCS400-series microcomputers with large-capacity
memory and architecture providing high program productivity. Each microcomputer has a 32-kHz
oscillator for clock, low-voltage (1.8 V) operating mode, and four low-power dissipation modes.
UThe HD404459 Series includes three chips: the HD404458 with an 8-kword ROM; the HD404459 with a
t416-kword ROM; and the HD4074459 with a 16-kword PROM (ZTATTM version).
eThe HD4074459 is a PROM version (ZTATTM microcomputer). A program can be written to the PROM by
a PROM writer, thus dramatically shortening system development periods and turnaround time (ZTATTM
eversions are 27256-compatible).
