STA321MPLTR

Audio Special Purpose Overview

The STA321MPLTR is a fully integrated audio processor manufactured by STMicroelectronics, designed for high-channel-count applications. It features eight channels and supports I2C and I2S interfaces for digital control and data transmission. The device operates within a supply voltage range of 3V to 3.6V and functions reliably across an extended temperature range of -40°C to 125°C (TJ). Housed in a 64-LQFP package with dimensions of 10x10 mm, it utilizes surface mount technology. The component implements full flexible amplification specifications, integrating processing capabilities directly into the amplifier architecture.

Audio Special Purpose Procurement Notes

This component is classified as discontinued by the manufacturer. Availability is limited to existing stock, and no new production batches are scheduled. Designers should verify current inventory levels with authorized distributors before finalizing procurement plans. Obsolescence status requires immediate attention for long-term supply chain stability.

Audio Special Purpose Selection Notes

Select this part for designs requiring an 8-channel integrated solution with I2C/I2S connectivity. Ensure the system power supply remains strictly between 3V and 3.6V to maintain operational integrity. Verify that the PCB layout accommodates the 64-TQFP (10x10) package footprint. Consider thermal management strategies given the 125°C maximum junction temperature rating.

Audio Special Purpose Part Context

The STA321MPLTR belongs to the STA321 product family from STMicroelectronics. It serves as a specialized audio integrated circuit combining processing and amplification functions. The 'MPLTR' suffix indicates the specific tape and reel packaging configuration for surface mount assembly.

Audio Special Purpose Replacement Considerations

The STA311BTR is listed as a similar replacement option by STMicroelectronics. Engineers should compare channel counts and interface compatibility before substitution.
