HT8659 - (HT8658 / HT8659) Voice Recorder

Download the HT8659 datasheet PDF. This datasheet also covers the HT8658 variant, as both devices belong to the same (ht8658 / ht8659) voice recorder family and are provided as variant models within a single manufacturer datasheet.

General Description

The HT8658/HT8659 are single chip CMOS LSIs using an ADM coding technology.

They are designed for applications on recording sounds.

The HT8658 and HT8659 have almost the same functions apart from the reset time.
