• Integrates IEEE 802.1AS (gPTP), IEEE 1722 (AVTP), and RTP protocols for standardized audio/video transport
• Supports up to 40 simultaneous audio channels with hardware-accelerated stream processing
• Includes hardware security engines for secure boot and secure firmware update capabilities
• Provides plug-and-play AVB functionality compliant with Avnu Alliance and IETF standards

Controllers Applications

• Professional audio networking equipment requiring precise clock synchronization
• Digital mixing consoles and audio interfaces utilizing AVB standards
• Smart speakers and connected audio endpoints with secure firmware management
• Automotive infotainment systems supporting high-fidelity audio streams

Controllers Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Check for End-of-Life (EOL) status notifications, as discontinuance may affect long-term supply stability. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet prior to assembly. Confirm package markings match the specific suffix to avoid counterfeit risks.

Controllers Selection Notes

Select this component when designing AVB audio endpoints requiring integrated protocol stacks without external processors. Consider the pinout compatibility if replacing previous LAN9360 variants. Evaluate thermal performance for the target operating environment, as the device operates within standard industrial temperature ranges. Verify interface requirements against the host processor's MAC capabilities before finalizing the design.

Controllers Part Context

This part belongs to the LAN9360 family of AVB controllers from Microchip Technology. It is specifically engineered for audio-centric applications where low latency and synchronization are critical. The series distinguishes itself by combining networking functions with audio-specific features like channel count support and security modules, targeting both consumer and professional audio markets.

Controllers Replacement Considerations

Consult Microchip official documentation for direct pin-to-pin replacements or functional equivalents within the LAN9360 series. Verify software compatibility if migrating between revisions. No third-party substitutes are officially confirmed; use only Microchip-approved alternatives.
