General Description :
The APR9301 device offers true single-chip solid-state storage capability and requires no
software or microcont-roller 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 appl
ications.
APLUS’s proprietary 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 device stores and reproduces voice signals in their natural forms,
eliminating distortion that is often introduced by encoding and compression. The device
combines a small size with low power consumption,non-volatility, and ease-of-use for a cost
effective solution to voice recording and playback
