Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

MS87V1021
Recording and Playback IC with Built-in 2-Mbit DRAM
PEDS87V1021-02
Issue Date: Feb. 20, 2002
Preliminary
GENERAL DESCRIPTION
The MS87V1021 is a single chip recording and playback IC that is controlled by the microcontroller in serial mode,
compresses voice with the 4-bit OKI ADPCM algorithm or 4-bit OKI ADPCM2 algorithm with high tone quality,
and has 2-Mbit DRAM in which recorded data is stored and 512-Kbit mask ROM in which fixed messages reside.
The MS87V1021 includes such features as Normal Recording and Playback, Delayed playback, Retroactive
playback, Fast forwarding, and Rewinding.
The internal memory in which voice data is stored allows a recording/playback system to be constructed merely by
externally connecting it to a microphone, a speaker driving amplifier, and a speaker.
FEATURES
•
Serial microcontroller interface (clock synchronized)
•
Built-in 512-Kbit mask ROM for fixed messages
ROM playback time:
Approx. 15 seconds (Fsam = 8.0 kHz)
Approx. 20 seconds (Fsam = 6.4 kHz)
Approx. 30 seconds (Fsam = 4.0 kHz)
•
Voice analyzing and synthesizing system:
4-bit OKI ADPCM or 4-bit OKI ADPCM2 algorithm
8-bit OKI non-linear PCM algorithm (for ROM playback only)
•

4.0 kHz, 5.3 kHz, 6.4 kHz, 8.0 kHz, or 10.6 kHz
•
Recording time:
Approx. 60 seconds (Fsam = 8.0 kHz)
Approx. 80 seconds (Fsam = 6.4 kHz)
Approx. 120 seconds (Fsam = 4.0 kHz)
•
Built-in 14-bit A-to-D and D-to-A converters
•
Built-in LPF: Attenuation rate –40 dB/oct
•
Number of phrases
Variable message: 254 phrases max.
Fixed phrases: 256 phrases max.
•
Source oscillation frequency: 4.096 MHz
•
Supply voltage: 2.7 to 3.6 V
•
Operating current:
15 mA max. (source oscillation frequency: 4.096 MHz, Supply voltage: 3.6 V)
•
Operating temperature: –20 to +70°C
•
Package: 32-pin TSOP Type I
