M2S025-FG484 Equivalent & Substitute Parts

Part Overview

The M2S025-FG484 is an ARM Cortex-M3 System On Chip (SOC) IC from Microchip Technology's SmartFusion2 product line. This embedded processor integrates a 166MHz ARM Cortex-M3 core with 25K Logic Modules FPGA fabric, 256KB Flash memory, and 64KB RAM in a 484-FPBGA package. The device supports multiple connectivity standards including CANbus, Ethernet, I2C, SPI, UART/USART, and USB, along with DDR, PCIe, and SERDES peripherals.

The M2S025-FG484 is classified as Active product status. Equivalent substitute parts are necessary when the primary part number becomes unavailable, when specific compliance certifications are required, or when design revisions necessitate alternative packaging variants within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2S025-FG484 is determined by strict equivalence across the following critical parameters:

Core Electrical Specifications: Identical ARM Cortex-M3 processor architecture, 166MHz clock speed, 256KB Flash memory, 64KB RAM, and 25K Logic Modules FPGA configuration.

Package and Physical Compatibility: Identical 484-FPBGA (23x23) package type with 267 I/O pins ensures mechanical and electrical pin compatibility.

Functional Peripherals: Identical support for DDR, PCIe, and SERDES peripherals, plus identical connectivity interfaces (CANbus, Ethernet, I2C, SPI, UART/USART, USB).

Environmental and Compliance Parameters: Identical operating temperature range (0°C to 85°C), identical Moisture Sensitivity Level 3 (168 Hours), and identical ECCN and HTSUS classifications.

The substitute parts M2S025-FGG484 and M2S025T-FGG484 meet all these criteria and are therefore electrically and mechanically interchangeable with the M2S025-FG484 within the same application context.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—M2S025-FG484, M2S025-FGG484, and M2S025T-FGG484—are electrically and mechanically equivalent and maintain Active product status from Microchip Technology.

The primary distinction between these parts is RoHS compliance status. The M2S025-FG484 is RoHS non-compliant, while both M2S025-FGG484 and M2S025T-FGG484 are RoHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS3 compliance, M2S025-FGG484 or M2S025T-FGG484 are the appropriate selections.

All parts share identical REACH status (REACH Unaffected), ECCN classification (3A991D), and HTSUS code (8542.39.0001). Selection between M2S025-FGG484 and M2S025T-FGG484 may be determined by inventory availability or specific procurement requirements, as both maintain identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

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

A: Yes. All three parts use the identical 484-FPBGA (23x23) package with 267 I/O pins in the same configuration. Pin assignments, signal definitions, and electrical characteristics are identical across all three part numbers.

Q: What is the difference between M2S025-FG484 and M2S025-FGG484?

A: The primary difference is RoHS compliance status. M2S025-FG484 is RoHS non-compliant, while M2S025-FGG484 is RoHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I substitute M2S025T-FGG484 for M2S025-FG484 in an existing design?

A: Yes. M2S025T-FGG484 is electrically and mechanically equivalent to M2S025-FG484. Both parts support identical processor architecture, memory configuration, FPGA logic modules, connectivity interfaces, and operating temperature range. The part number suffix variation does not affect functional compatibility.

Q: Are there any differences in memory configuration between these parts?

A: No. All three parts contain identical Flash memory (256KB), RAM memory (64KB), and FPGA logic module count (25K). Memory performance and addressing are identical.

Q: Which part should I select for RoHS-compliant applications?

A: For applications requiring RoHS3 compliance, select either M2S025-FGG484 or M2S025T-FGG484. Both parts meet RoHS3 requirements. The M2S025-FG484 is RoHS non-compliant and should not be used in RoHS-regulated applications.

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

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

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. Identical moisture handling and storage requirements apply to M2S025-FG484, M2S025-FGG484, and M2S025T-FGG484.
