General Description
The APR9301 de vice offers true single-chip solid-state storage capability and requires no software or microcontroller support. It provides high-quality recording and playback with a single 20- to 30-second message. It is ideal for portable voice recorders, toys, and many other consumer and industrial applications. APLUS integrated analog/multi-level storage technology is implemented in advanced Flash non-volatile memory cells, each of which can typically store more than 256 voltage levels. The APR9301 -V2 stores and reproduces voice signals in their natural forms, eliminating the distortion that is often introduced by encoding and compression. The device combines a small size with low power consumption, nonvolatility, and ease-of-use for a cost effective solution to voice recording and playback. .
