The 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.
The HD404459 Series includes three chips: the HD404458 with an 8-kword ROM; the HD404459 with a 16-kword ROM; and the HD4074459 with a 16-kword PROM (ZTATTM version).
The HD404459 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 versions are 27256-compatible).ZTATTM: Zero Turn Around Time ZTAT is a trademark of Hitachi, Ltd.
