Substitute Part Grouping Explanation

Substitution for the ATSAMA5D22A-CUR is determined by strict equivalence across the following critical parameters:

• Processor Architecture: ARM Cortex-A5 core with identical instruction set
• Clock Speed: 500MHz operation
• Package Configuration: 196-TFBGA (11x11) form factor
• I/O Voltage: 3.3V supply
• Temperature Range: -40°C to 85°C operational envelope
• Peripheral Integration: Identical RAM controllers (LPDDR1, LPDDR2, LPDDR3, DDR2, DDR3, DDR3L, QSPI), display controllers, Ethernet (10/100Mbps), USB 2.0 + HSIC, and interface protocols (I2C, SMC, SPI, UART, USART, QSPI)
• Security Features: ARM TrustZone, Boot Security, Cryptography, RTIC, Secure Fusebox, Secure JTAG, Secure Memory, Secure RTC
• Compliance: ROHS3, REACH Unaffected, identical ECCN and HTSUS codes

The identified substitutes maintain full electrical and functional compatibility with the original part while differing in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The ATSAMA5D22A-CUR is obsolete and should be replaced in new designs. Both substitute parts maintain complete electrical and functional equivalence:

ATSAMA5D22C-CUR is the direct functional equivalent with active product status. This part differs only in packaging configuration, supplied in Tape & Reel format suitable for automated assembly processes. Selection of this part is appropriate for production environments requiring standard component packaging.

ATSAMA5D23A-CUR is the manufacturer-recommended alternative, also with active product status. This part maintains identical electrical specifications and peripheral integration. Selection of this part aligns with Microchip Technology's current product recommendations for the SAMA5D2 series.

Both substitutes satisfy ROHS3 compliance, REACH requirements, and export control classifications identical to the original part. Inventory availability and supply chain considerations should guide final selection between the two active alternatives.

Frequently Asked Questions (FAQ)

Q: Can ATSAMA5D22C-CUR directly replace ATSAMA5D22A-CUR in existing designs?

A: Yes. The parts are electrically and functionally identical. The only difference is packaging configuration: ATSAMA5D22C-CUR is supplied in Tape & Reel format while ATSAMA5D22A-CUR is supplied in bulk. PCB layout, schematic integration, and firmware compatibility remain unchanged.

Q: What is the difference between ATSAMA5D22C-CUR and ATSAMA5D23A-CUR?

A: Both parts are functionally equivalent substitutes for the obsolete ATSAMA5D22A-CUR. ATSAMA5D22C-CUR is supplied in Tape & Reel packaging; ATSAMA5D23A-CUR is supplied in bulk packaging. Electrical specifications, performance characteristics, and peripheral integration are identical.

Q: Are the substitute parts compatible with existing PCB designs?

A: Yes. Both substitute parts use the identical 196-TFBGA (11x11) package footprint, 3.3V I/O voltage, and operating temperature range. No PCB redesign is required.

Q: Do the substitute parts support the same security features?

A: Yes. Both ATSAMA5D22C-CUR and ATSAMA5D23A-CUR include identical security implementations: ARM TrustZone, Boot Security, Cryptography, RTIC, Secure Fusebox, Secure JTAG, Secure Memory, and Secure RTC.

Q: What memory controller options are available in the substitute parts?

A: Both substitutes support LPDDR1, LPDDR2, LPDDR3, DDR2, DDR3, DDR3L, and QSPI memory controllers, identical to the original part.

Q: Are there compliance or export restrictions on the substitute parts?

A: No. Both substitutes maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN (5A992C) and HTSUS (8542.31.0001) classifications as the original part.
