Substitute Part Grouping Explanation

Substitution eligibility for the ATSAMA5D22A-CU 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 Format: 196-TFBGA (11x11) ball grid array
• I/O Voltage: 3.3V supply
• Operating Temperature Range: -40°C to 85°C
• Memory Controller Support: LPDDR1, LPDDR2, LPDDR3, DDR2, DDR3, DDR3L, QSPI
• Interface Set: 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

Substitute parts must maintain identical electrical characteristics, pinout compatibility, and functional feature parity to ensure direct replacement capability without design modification.

Parameter Comparison

Engineering Selection Recommendations

The ATSAMA5D22A-CU is obsolete and should be replaced in new designs and production. Two active alternatives are available:

ATSAMA5D22C-CU is the direct substitute, maintaining identical electrical and functional specifications with active product status. This part is available in Tray packaging and represents the primary replacement path for existing designs.

ATSAMA5D23A-CUR is the manufacturer-recommended alternative, offering identical core functionality and specifications. This part is designated as the preferred long-term solution by Microchip Technology.

Both substitute parts maintain full compatibility with existing PCB layouts, firmware, and system designs based on the ATSAMA5D22A-CU. Selection between the two substitutes should be based on packaging requirements and supply chain availability, as electrical and functional performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can ATSAMA5D22C-CU and ATSAMA5D23A-CUR be used interchangeably with ATSAMA5D22A-CU?

A: Yes. Both parts are direct electrical and functional equivalents. They share identical processor architecture, clock speed, package format, I/O voltage, operating temperature range, memory controller support, interface sets, and security features. No design modifications are required for substitution.

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

A: Both parts are functionally identical. The primary difference is packaging: ATSAMA5D22C-CU is supplied in Tray format, while ATSAMA5D23A-CUR is the manufacturer-recommended part. Selection should be based on packaging requirements and supply availability.

Q: Are there any pinout differences between the substitute parts and the original ATSAMA5D22A-CU?

A: No. All three parts use the 196-TFBGA (11x11) package with identical pinout. Direct PCB replacement is supported without layout modifications.

Q: Do the substitute parts support the same memory configurations?

A: Yes. ATSAMA5D22C-CU and ATSAMA5D23A-CUR support identical RAM controllers: LPDDR1, LPDDR2, LPDDR3, DDR2, DDR3, DDR3L, and QSPI. Memory subsystem designs require no changes.

Q: Are compliance certifications maintained across all three parts?

A: Yes. All parts are RoHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Regulatory requirements are satisfied by any of the three parts.

Q: What is the operating temperature range for these parts?

A: All three parts operate across -40°C to 85°C (TA). Thermal design considerations remain unchanged when substituting.
