ML2302 - Recording and Playback LSI

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.

Key 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.
