Microprocessors Procurement Notes

This component is officially obsolete and no longer manufactured by Microchip Technology. Verification of availability should focus on finding direct replacement parts, such as the ATSAMA5D27C-CN, rather than sourcing the original model. Ensure that any substitute components meet the required pinout and functional specifications for your design. Consult official product change notifications for lifecycle details.

Microprocessors Selection Notes

Designers should consider the ATSAMA5D27C-CN as the primary alternative due to its identical architectural foundation within the SAMA5D2 family. Verify that the replacement part supports the same 289-LFBGA package and 500MHz clock speed. Review the specific errata and datasheet updates for the newer variant to ensure compatibility with existing software drivers and hardware layouts.
