Engineering Selection Recommendations

The ATSAMA5D26B-CN is obsolete and should be replaced with active alternatives for new designs and production continuity. Both ATSAMA5D26C-CN and ATSAMA5D26A-CN provide identical electrical and mechanical specifications with active product status from Microchip Technology.

ATSAMA5D26C-CN is supplied in Tray packaging with 1139 units in stock inventory. ATSAMA5D26A-CN is supplied with 975 units in stock inventory. Both parts maintain full compliance with ROHS3, REACH, and export control requirements (ECCN 5A992C, HTSUS 8542.31.0001).

Selection between the two active alternatives depends on packaging requirements and inventory availability. No functional or electrical differences exist between these parts.

Frequently Asked Questions (FAQ)

Q: Can ATSAMA5D26C-CN or ATSAMA5D26A-CN be used as direct replacements for ATSAMA5D26B-CN?

A: Yes. Both parts are electrically and mechanically identical to ATSAMA5D26B-CN across all specified parameters including processor core, clock speed, package format, I/O voltage, temperature range, memory controllers, interfaces, and security features.

Q: What is the difference between ATSAMA5D26C-CN and ATSAMA5D26A-CN?
