Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATSAMA5D24A-CUR is determined by strict equivalence across the following critical parameters:

• Processor Architecture: ARM Cortex-A5 core with identical instruction set compatibility
• Clock Speed: 500MHz operation
• Package Format: 256-TFBGA (8x8) ball grid array with identical pinout
• I/O Voltage: 3.3V supply and signaling
• Temperature Range: -40°C to 85°C operating specification
• Peripheral Integration: Identical RAM controllers, display interfaces, Ethernet, USB, and security features
• Compliance Standards: ROHS3 compliance and equivalent moisture sensitivity rating

The ATSAMA5D24C-CUR qualifies as a direct substitute based on complete alignment across all electrical, mechanical, and functional parameters within the SAMA5D2 product line.

Parameter Comparison

Engineering Selection Recommendations

The ATSAMA5D24C-CUR is the qualified substitute for the obsolete ATSAMA5D24A-CUR. Both parts maintain identical electrical specifications, pinout compatibility, and functional feature sets within the SAMA5D2 microprocessor family. The primary distinction is product lifecycle status: ATSAMA5D24A-CUR is obsolete, while ATSAMA5D24C-CUR maintains active production status with confirmed inventory availability (3100 units in stock versus 723 units for the obsolete variant).

For new designs and ongoing production requirements, ATSAMA5D24C-CUR is the appropriate selection. Existing designs using ATSAMA5D24A-CUR can transition to ATSAMA5D24C-CUR without circuit modification, as both parts are pin-compatible and functionally equivalent. ROHS3 compliance and identical moisture sensitivity ratings ensure equivalent handling and storage requirements.
