Substitute Part Grouping Explanation

Substitution eligibility for the A2F500M3G-FG484 is determined by strict equivalence across the following critical parameters:

• Core architecture (ARM Cortex-M3 processor with ProASIC3 FPGA integration)
• Memory configuration (512KB Flash, 64KB RAM)
• Gate count (500K FPGA gates)
• Operating frequency (80MHz)
• Package specification (484-FPBGA, 23x23mm footprint)
• I/O pin count (MCU: 41, FPGA: 128)
• Operating temperature range (0°C ~ 85°C)
• Peripheral set (DMA, POR, WDT, EBI/EMI, Ethernet, I2C, SPI, UART/USART)

The A2F500M3G-FGG484 meets all substitution criteria as a parametric equivalent. Differences exist only in packaging format (Tray vs. alternative tray specification) and RoHS compliance status.

Engineering Selection Recommendations

The A2F500M3G-FGG484 is a direct parametric equivalent to the A2F500M3G-FG484. Both parts are Active products from Microchip Technology with identical electrical and mechanical specifications.

Selection between these parts should be based on:

• RoHS compliance requirements: The A2F500M3G-FGG484 is ROHS3 Compliant, while the A2F500M3G-FG484 is RoHS non-compliant. Applications subject to RoHS directives must use the FGG484 variant.
• Inventory availability: The A2F500M3G-FGG484 has 1539 units in stock compared to 695 units for the FG484.
• Procurement specifications: Verify that your design documentation and supply chain requirements specify which RoHS variant is acceptable.

Both parts carry identical ECCN (3A991D) and HTSUS (8542.39.0001) classifications and are subject to the same export control and tariff considerations.

Frequently Asked Questions (FAQ)

Q: Can the A2F500M3G-FGG484 be used as a direct replacement for the A2F500M3G-FG484 in existing designs?

A: Yes. Both parts are parametrically identical in all electrical and mechanical specifications, including processor architecture, memory configuration, I/O pin count, package dimensions, and operating temperature range. The only difference is RoHS compliance status. Verify that your application and supply chain requirements permit the use of a ROHS3 Compliant variant.

Q: What is the significance of the FG484 versus FGG484 designation?

A: The difference in the part number suffix reflects the RoHS compliance status. The FG484 is RoHS non-compliant, while the FGG484 is ROHS3 Compliant. The electrical and mechanical specifications are identical.

Q: Are the 484-FPBGA packages physically interchangeable?

A: Yes. Both parts use the 484-FPBGA (23x23mm) package with identical pin assignments, footprint, and mechanical dimensions. PCB layouts designed for one part are compatible with the other.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: ARM Cortex-M3 core processor, 80MHz operating frequency, 512KB Flash memory, 64KB RAM, 500K FPGA gate count, 484-FPBGA package, 41 MCU I/O pins, 128 FPGA I/O pins, and 0°C to 85°C operating temperature range.

Q: Does the RoHS compliance difference affect circuit performance or reliability?

A: No. RoHS compliance refers to the materials and manufacturing process used to produce the component, not its electrical performance or reliability characteristics. Both parts meet identical performance and reliability specifications.
