ML2302

Recording and Playback LSI with Built-in 2-Bit ADPCM2 Supported FIFO

GENERAL DESCRIPTION

The ML2302 is a recording and playback LSI with built-in FIFO memories for buffering. It employs the new 2-bit

ADPCM2 algorithm in addition to conventional 4-bit OKIADPCM and 4-bit OKIADPCM2 algorithms.

The ML2302 operates at 2.7 to 3.6 V and supports a variety of applications.

FEATURES

•

Built-in two 1024-bit FIFOs

(buffering time of 32 ms when using 8 kHz sampling frequency and 4-bit ADPCM)

Supports five compression algorithms for recording and playback:

2-bit OKIADPCM2; 4/5/6/7-bit OKIADPCM2; 4-bit OKIADPCM; 8/16-bit straight PCM; 8-bit OKI

Nonlinear PCM

•

Source oscillation frequency 16.384 MHz

Sampling frequency (fsam)

4.0 to 12.8 kHz (OKIADPCM2)

4.0 to 25.6 kHz (8-bit straight PCM)

•

Supports 8-bit bus interface.

Built-in voice level detection function (VAC)

Built-in noise injection function

Supports external DAC interface.

Built-in volume control circuit

(0 dB to –44 dB: –2 dB step, –44 dB to –80 dB: –4 dB step)

Built-in 14-bit A/D converter and 14-bit D/A converter

Built-in low pass filter (LPF)

•

(recording side: analog filter, playback side: digital filter)

•

Built-in speaker amplifier (100 mW, 8Ω)

Power supply voltage : +2.7 to +3.6 V
