HD4074459 Datasheet (hd4074458 / Hd4074459) Microcontroller

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD404459 Series.

General Description

The HD404459 Series is a member of the 4-bit HMCS400-series microputers with large-capacity memory and architecture providing high program productivity.

Each microputer 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;
