Flash-driving Recording and Playback IC
GENERAL DESCRIPTION
The MSM 9888L is a recording and playback IC that is controlled by the micro-controller in serial
mode, compresses voice with the Oki ADPCM system with high tone quality, and directly stores
voice data inthe serial voice flash momory. This IC can operate in a range of 2.7 to 3.6 V and
contains a mask ROM. Since the package is small and backup is not needed, this recording and
playback IC is suitable for the voice system such as handy terminals.
