Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M2S005S-FG484I are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

• Core processor architecture and speed (ARM Cortex-M3 at 166MHz)
• Memory configuration (128KB flash, 64KB RAM)
• FPGA fabric capacity (5K logic modules)
• Package form factor and pin count (484-FPBGA with 209 I/O)
• Operating temperature range (-40°C to 100°C)
• Peripheral and connectivity feature set (CANbus, Ethernet, I2C, SPI, UART/USART, USB)
• Base product number (M2S005)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in packaging designation or compliance certifications do not affect functional or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both M2S005S-FG484I and M2S005-FGG484I are parametrically equivalent and functionally interchangeable for applications requiring SmartFusion2 FPGA-MCU integration. The primary distinction between these parts is RoHS compliance status. The M2S005-FGG484I meets ROHS3 compliance requirements, while the M2S005S-FG484I is RoHS non-compliant. Selection between these parts should be based on regulatory and environmental requirements applicable to the end application. Both parts maintain identical electrical performance, memory configuration, I/O count, and thermal operating range. Inventory availability and supply chain considerations may also influence part selection, as current stock levels differ between the two variants.

Frequently Asked Questions (FAQ)

Q: Are M2S005S-FG484I and M2S005-FGG484I pin-for-pin compatible?

A: Yes. Both parts use the 484-FPBGA (23x23) package with 209 I/O pins in identical pin configurations. They are mechanically and electrically interchangeable at the board level.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance certification. M2S005-FGG484I is ROHS3 compliant, while M2S005S-FG484I is RoHS non-compliant. All electrical specifications, memory, processing speed, and peripheral functionality are identical.

Q: Can I substitute M2S005-FGG484I for M2S005S-FG484I in an existing design?

A: Yes, provided your application does not have specific RoHS exemption requirements or regulatory constraints that mandate the non-compliant variant. The ROHS3 compliant version is generally preferred for new designs and applications subject to environmental regulations.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate at 166MHz, support the same -40°C to 100°C temperature range, and have identical memory and FPGA specifications. Thermal performance and processing capability are equivalent.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts have MSL 3 rating with a 168-hour floor life. Standard moisture control and handling procedures for BGA packages apply to both variants.

Q: Do these parts support the same connectivity interfaces?

A: Yes. Both M2S005S-FG484I and M2S005-FGG484I include CANbus, Ethernet, I2C, SPI, UART/USART, and USB connectivity interfaces.
