M2S025T-FG484 Equivalent & Substitute Parts

Part Overview

The M2S025T-FG484 is an ARM Cortex-M3 System On Chip (SOC) IC from Microchip Technology's SmartFusion2 product line. This embedded processor integrates a 166MHz Cortex-M3 core with 25K logic modules FPGA fabric, 256KB flash memory, and 64KB RAM in a 484-FPBGA package. The device is currently in active production status and supports multiple connectivity standards including Ethernet, CAN, USB, SPI, I2C, and UART interfaces.

Equivalent substitute parts are necessary when the primary part number becomes unavailable due to supply constraints, inventory fluctuations, or procurement optimization. Substitute parts maintain identical electrical and mechanical specifications while potentially offering different RoHS compliance status or packaging variants.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M2S025T-FG484 are determined by strict equivalence across all electrical and mechanical parameters. The substitution criteria are based on the following key parameters:

• Core processor architecture and speed (ARM Cortex-M3 at 166MHz)
• Memory configuration (256KB flash, 64KB RAM)
• FPGA fabric capacity (25K logic modules)
• Package specification (484-FPBGA with 23x23 footprint)
• I/O count (267 pins)
• Operating temperature range (0°C to 85°C)
• Peripheral and connectivity feature set

The M2S025T-FG484 has two parametric equivalents: M2S025-FGG484 and M2S025T-FGG484. Both parts maintain identical electrical specifications and package dimensions. The primary difference between the main part and its substitutes is the RoHS compliance status and packaging variant designation (FG versus FGG suffix).

Parameter Comparison

Engineering Selection Recommendations

All three parts—M2S025T-FG484, M2S025-FGG484, and M2S025T-FGG484—are functionally equivalent and interchangeable at the electrical and mechanical level. Selection between these parts should be based on compliance requirements and product status:

For applications requiring RoHS3 compliance, M2S025-FGG484 and M2S025T-FGG484 are the appropriate selections. Both substitute parts carry ROHS3 Compliant status, whereas the M2S025T-FG484 is RoHS non-compliant.

For applications without RoHS compliance mandates, all three parts are suitable. The M2S025T-FG484 remains in active production status and is available in inventory.

All parts maintain identical REACH Unaffected status and ECCN classification (3A991D), confirming regulatory equivalence for export and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Are M2S025-FGG484 and M2S025T-FGG484 pin-for-pin compatible with M2S025T-FG484?

A: Yes. All three parts use the 484-FPBGA (23x23) package with 267 I/O pins. PCB layout and footprint are identical across all variants.

Q: What is the difference between the FG and FGG package designations?

A: The FG and FGG suffixes indicate packaging variants within the same 484-FPBGA form factor. Both designations refer to the same physical package specification and are mechanically and electrically equivalent.

Q: Can I substitute M2S025T-FG484 with M2S025-FGG484 in a design requiring RoHS compliance?

A: M2S025-FGG484 is ROHS3 Compliant, whereas M2S025T-FG484 is RoHS non-compliant. If RoHS compliance is a design requirement, M2S025-FGG484 or M2S025T-FGG484 must be used instead of M2S025T-FG484.

Q: Are the memory specifications identical across all three parts?

A: Yes. All parts contain 256KB flash memory and 64KB RAM with identical access timing and performance characteristics.

Q: Do all three parts support the same peripheral interfaces?

A: Yes. All parts include DDR, PCIe, and SERDES peripherals, with identical support for CANbus, Ethernet, I2C, SPI, UART/USART, and USB connectivity.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level 3 with a 168-hour floor life rating. Standard moisture control procedures during storage and handling are required.
