STA013$

Encoders, Decoders, Converters Overview

The STA013 is a fully integrated MPEG Layer III audio decoder supporting ISO/IEC 11172-3 (MPEG 1), ISO/IEC 13818-3.2 (MPEG 2), and the MPEG 2.5 extension for lower sampling rates. It decodes stereo, dual channel, and mono streams with data rates from 8 Kbit/s to 320 Kbit/s. The device operates on a 2.4V to 3.6V supply, consuming 85mW at 2.4V. It features a serial bitstream input interface, I2C control bus, and a software-programmable PCM output interface compatible with common DAC architectures.

Encoders, Decoders, Converters Procurement Notes

Verify the specific package suffix against the datasheet ordering numbers: STA013$ for SO28, STA013T$ for TQFP44, or STA013B$ for LFBGA 8x8. Confirm that the application board design matches the required pin connections for the selected package variant, particularly regarding test enable and scan enable signals.

Encoders, Decoders, Converters Selection Notes

Select the appropriate package based on PCB space constraints and thermal requirements. Ensure the system clock source matches the supported frequencies of 10 MHz, 14.31818 MHz, or 14.7456 MHz. Verify that the host microcontroller can support the I2C protocol for configuration and the serial interface for bitstream input.

Encoders, Decoders, Converters Part Context

The STA013 belongs to STMicroelectronics' family of single-chip MPEG audio decoders. It is designed as a high-flexibility solution for embedded audio processing, integrating the decoder core, channel configuration, and output buffering into a single CMOS component.
