• Operates as an OTN controller within the embedded microcontroller family
• Supports surface-mount installation in a large-scale BGA package

Applications

• Optical Transport Network (OTN) systems
• Network processor implementations
• Specialized interface IC solutions

Procurement Notes

Verify the specific ordering suffix and package configuration against official Microchip documentation before procurement. Confirm that the required version aligns with the intended system design, particularly regarding the absence of encryption features. Ensure compatibility with the specified 1932-BBGA footprint and thermal operating ranges during the sourcing process.

Selection Notes

Select this component when a dedicated OTN network processor with a DIGI 100GX interface is required. It is suitable for designs needing specialized interface control without built-in encryption. Consider the 1932-BBGA package size and surface-mount requirements. Verify that the operational temperature range meets the environmental constraints of the target application.

Part Context

This part belongs to the PM5981 family of network processors manufactured by Microchip Technology. It is closely related to variants such as the PM5991B-FEI, which shares similar packaging but may differ in interface specifications. The PM5981 series serves as a core solution for optical transport networking, providing specialized processing capabilities distinct from general-purpose microcontrollers.

Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers. Cross-reference with other members of the PM5981 family or compatible OTN controllers if direct substitution is necessary. Ensure pinout and functional equivalence are confirmed through datasheet comparison.
