Engineering Selection Recommendations

Both ATSAMA5D22C-CUR and ATSAMA5D23A-CUR are direct functional equivalents to the obsolete ATSAMA5D22B-CUR. Selection between these substitutes is based on product status and supply chain considerations:

ATSAMA5D22C-CUR is the primary substitute, offering active product status with identical electrical and functional specifications. This part is supplied in Tape & Reel packaging, suitable for automated assembly processes.

ATSAMA5D23A-CUR is the manufacturer-recommended alternative, also maintaining active product status with complete functional equivalence. This part provides an additional sourcing option for design continuity.

Both substitutes comply with ROHS3 and REACH requirements, maintain identical security certifications, and support the full range of peripheral interfaces and memory controllers specified for the original part. Selection should be based on availability, packaging requirements, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Are ATSAMA5D22C-CUR and ATSAMA5D23A-CUR pin-compatible with ATSAMA5D22B-CUR?

A: Yes. All three parts use the identical 196-TFBGA (11x11) package configuration with matching pinout, electrical characteristics, and functional integration.

Q: Can I use these substitutes in existing PCB designs without modification?

A: Yes. The substitutes maintain 100% electrical and functional compatibility with the original part. No PCB redesign or layout changes are required.

Q: What is the difference between the packaging options?

A: ATSAMA5D22C-CUR is supplied in Tape & Reel (TR) format for high-volume automated assembly. ATSAMA5D23A-CUR packaging is not specified in the provided data. Both are surface-mount components suitable for standard PCB assembly processes.
