• Central Office (CO) systems
• Voice-enabled DSLAMs
• PBX/KTS systems
• Multi-Dwelling Units (MDU)

Telecom Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified partners. Confirm RoHS3 compliance status and check for Product Change Notices regarding packaging or marking updates. Ensure the specific 128-TQFP variant matches system requirements before procurement.

Telecom Selection Notes

Select this processor for applications requiring high channel density and integrated line testing. It is suitable for environments needing software-upgradeable voice control. Consider compatibility with existing NGCC chipsets and verify power supply constraints against the specified voltage range during design integration.

Telecom Part Context

This component belongs to the LE79xxx series of telecom interface ICs manufactured by Microchip Technology. It represents a second-generation platform within the VoiceEdge family, offering enhanced performance over previous models like the LE79112 while maintaining similar interface standards.

Telecom Replacement Considerations

The LE79112AKVC is a related model in the same series. Verify functional equivalence and pin compatibility if considering substitution, as both belong to the LE79xxx family.
