STA013T$013TR

Encoders, Decoders, Converters Overview

The STA013T$013TR is a single-chip MPEG Layer III audio decoder manufactured by STMicroelectronics. It supports ISO/IEC 11172-3 (MPEG 1) and ISO/IEC 13818-3.2 (MPEG 2) standards, including 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. It features digital volume control, bass/treble adjustment, and an I2C interface for ancillary data extraction. Powered by low power 3.3V CMOS technology, it operates at 2.4V to 3.6V with typical power consumption of 85mW at 2.4V.

Encoders, Decoders, Converters Procurement Notes

Verify the specific package suffix ($013TR) against the official datasheet to confirm the TQFP44 form factor. Ensure the ordering number matches the exact revision required for the design. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.

Encoders, Decoders, Converters Selection Notes

Select this component when designing systems requiring standalone MPEG Layer III decoding without external DSP resources. Consider the available pin count in the TQFP44 package relative to the board layout constraints. Verify that the host microcontroller can support the required I2C communication protocol for configuration and status monitoring.

Encoders, Decoders, Converters Part Context

This part belongs to the STA013 family of audio decoders, which includes variants such as the SO28 and LFBGA packages. The $013TR suffix indicates the specific tape and reel packaging for the TQFP44 version. This family was designed to provide high flexibility for embedded audio applications during its active production period.

Encoders, Decoders, Converters Replacement Considerations

Check for updated audio decoder ICs from STMicroelectronics or other manufacturers offering similar MPEG Layer III support. Verify compatibility with existing software drivers and I2C register maps if substituting with a newer generation decoder chip.
