Product Summary

The MAS3587F-B2 is a single-chip codec. The MAS3587F-B2 is for use in memory-based voice recording and playback applications. Due to embedded memories, the embedded DC/ DC up-converter, and the very low power consumption, the MAS3587F-B2 is ideally suited for portable electronics. The MAS3587F-B2 implements a voice encoder and decoder that is compliant to the ITU Standard G.729 Annex A. This standard works on 8 kHz, 16 bit, mono audio data that is compressed to 1 bit per audio sample. One second of compressed audio data uses 1000 bytes of memory.

Parametrics

MAS3587F-B2 absolute maximum ratings: (1)VIdig Input voltage, all digital inputs: 0.3, VSUP +0.3 V; (2)IIdig Input current, all digital inputs: 20, +20 mA; (3)IOut Current, all digital outputs: 0.5 A; (4)IOutDC Current DCSO: 1.5 A; (5)TS Storage temperature: 40, 125 °C; (6)VII2C Input Voltage, I2C-Pins I2CC, I2CD: 0.3, 5.5 V.

Features

MAS3587F-B2 features: (1)Single-chip G.729 decoder; (2)G.729 Annex A encoder; (3)ITU compliance tests passed; (4)Parallel input and parallel output of coded bitstream data; (5)Input audio data read from an I2S bus (in various formats); (6)Output audio data delivered via an I2S bus (in various formats); (7)Digital volume / mute; (8)Low power dissipation (150 mW for encoder, 80 mW for decoder @ 3.3 V); (9)Supply voltage range: 1.0 V to 3.6 V due to built-in DC/DC converter (1-cell battery operation); (10)Adjustable power supply supervision; (11)Power-off function; (12)Additional functionality achievable via download software (ADPCM encoder/decoder).
