AF-301Y00SR

Specialized ICS Overview

The AF-301Y00SR is an ultra-low power analog front-end (AFE) ASIC designed for True Wireless Stereo (TWS) applications. Manufactured by Qorvo and now under Semtech following the acquisition of Qorvo's Force Sense Business, this component supports always-on sensing tasks. It samples sensing signals to off-load the host processor, allowing the main system to remain in sleep mode during operation. The device is packaged in Tape & Reel (TR) format and maintains an active part status.

Specialized ICS Feature Summary

• Ultra-low power consumption optimized for battery-constrained TWS devices
• Enables always-on functionality by sampling sensing signals independently
• Off-loads processing tasks from the host MCU to extend standby time

Specialized ICS Applications

• True Wireless Stereo (TWS) earbuds
• Always-on voice or gesture detection systems
• Wearable health monitoring sensors

Specialized ICS Procurement Notes

Verify current manufacturer attribution as Semtech due to the recent acquisition of Qorvo's Force Sense Business. Confirm package type is Tape & Reel (TR). Ensure compatibility with existing BOMs referencing Qorvo branding. Check for any product change notifications affecting pinout or electrical characteristics.

Specialized ICS Selection Notes

Select this AFE when minimizing host CPU wake-ups is critical for battery life. Ideal for applications requiring continuous sensor data acquisition without significant power drain. Suitable for compact wearable form factors where low-power signal conditioning is required before digital processing.

Specialized ICS Part Context

Part of the AF-301 series of ultra-low power analog front ends. The SR suffix typically denotes specific packaging or tape/reel configuration. This component bridges analog sensor inputs and digital host processors in wireless audio and wearable ecosystems.

Specialized ICS Replacement Considerations

Consult official substitution lists from Semtech or Qorvo for direct replacements. Verify functional equivalence if sourcing from alternative vendors. No public substitute part numbers are confirmed in available documentation.
