M2S050-FCS325I Equivalent & Substitute Parts

Part Overview

The M2S050-FCS325I is an ARM Cortex-M3 System On Chip (SOC) from Microchip Technology's SmartFusion2 product line. This embedded IC integrates a 166MHz processor with 50K logic modules FPGA fabric, 256KB flash memory, and 64KB RAM in a 325-FCBGA package. The device is currently active in production and widely used in applications requiring combined MCU and FPGA functionality with comprehensive connectivity options including Ethernet, CAN, USB, and serial interfaces.

Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative configurations within the same product family that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the M2S050-FCS325I is determined by strict equivalence across the following critical parameters:

• Core processor architecture and speed (ARM Cortex-M3 at 166MHz)
• Memory configuration (256KB flash, 64KB RAM)
• FPGA capacity (50K logic modules)
• Physical package specification (325-FCBGA 11x11 footprint)
• I/O pin count (200 pins)
• Operating temperature range (-40°C to 100°C)
• Moisture sensitivity classification (MSL 3)
• Series family (SmartFusion2)

The M2S050-FCSG325I meets all these criteria and qualifies as a parametric equivalent. Both parts share identical electrical specifications, pinout, and thermal characteristics. The difference between these part numbers reflects manufacturing date code or packaging tray configuration, not functional or electrical variation.

Parameter Comparison

Engineering Selection Recommendations

Both M2S050-FCS325I and M2S050-FCSG325I are functionally and electrically equivalent for circuit design and PCB layout purposes. Selection between these parts should be based on compliance requirements and regulatory constraints applicable to the end application.

The M2S050-FCSG325I offers ROHS3 compliance, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring RoHS-compliant components. The M2S050-FCS325I, while RoHS non-compliant, remains suitable for applications without such regulatory requirements.

Both parts maintain identical electrical performance, pinout compatibility, and thermal characteristics. No design modifications or re-qualification are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are M2S050-FCS325I and M2S050-FCSG325I pin-for-pin compatible?

A: Yes. Both parts use the 325-FCBGA (11x11) package with 200 I/O pins in identical positions. PCB layouts and schematics require no modification for substitution.

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

A: The primary difference is RoHS compliance status. M2S050-FCSG325I is ROHS3 compliant, while M2S050-FCS325I is RoHS non-compliant. All electrical specifications, memory configuration, processing speed, and peripheral functionality are identical.
