STA013B$

Encoders, Decoders, Converters Overview

The STA013B$ is a single-chip MPEG Layer III audio decoder manufactured by STMicroelectronics, housed in an LFBGA64 package. It supports ISO/IEC 11172-3 (MPEG 1), ISO/IEC 13818-3.2 (MPEG 2), and the MPEG 2.5 extension for lower sampling frequencies. The device decodes stereo, dual channel, and mono bitstreams with data rates from 8 Kbit/s to 320 Kbit/s. Operating on a low power 3.3V CMOS technology, it consumes 85mW at 2.4V. Key features include digital volume control, bass and treble adjustment, I2C ancillary data extraction, and a serial PCM output interface.
