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.
FEATURES
* Voice analyzing and synthesizing system : 4-bit OKI ADPCM system*8-bit OKI non-linear PCM system (for ROM playback only) * Built-in 12-bit A/D*D/A converter * Built-in LPF : Attenuation rate -40 dB/oct * Sampling frequency (for 4.096 MHz of source oscillation frequency) : 2.0 kHz, 2.7 kHz, 3.2kHz, 4.0 kHz, 5.3 kHz, 6.4 kHz, 8 kHz * External memory for variable message : 1Mb, 2Mb, 4Mb, 8Mb, serial voice flash memory * Recording time (When the 1Mb serial voice flash is used) : Approximately 32 seconds (Fsam=8.0 kHz) : Approximately 40 seconds (Fsam=6.4 kHz) : Approximately 65 seconds (Fsam=4.0 kHz) * Built-in 512Kb mask ROM for fixed message * Playback time for fixed message : Approximately 15 seconds (Fsam=8.0 kHz) : Approximately 20 seconds (Fsam=6.4 kHz) : Approximately 31 seconds (Fsam=4.0 kHz) * Number of pharase Variable message : 63 phrases Fixed message : 255 phrases * Any data can be written to and read from a part in the voice flash memory. * Serial microcontroller interface * Source oscillation frequency : 4 MHz to 6 MHz * Supply voltage : 2.7 V to 3.6 V * Operating temperature : -10C to 70C * Package : 30-pin plastic SSOP (SSOP30-P-56-0.65-K)(Product name : MSM9888LGS-AK)

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
