M2S090-FCS325I Equivalent & Substitute Parts

Part Overview

The M2S090-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 90K logic modules FPGA fabric, 512KB flash memory, and 64KB RAM in a 325-FCBGA package. The device is currently in active production status with 896 units available in inventory. Substitute parts are identified when electrical specifications, package compatibility, and functional architecture remain identical across manufacturing variants.

Substitute Part Grouping Explanation

The M2S090T-FCS325I qualifies as a parametric equivalent to the M2S090-FCS325I based on the following criteria:

• Identical core processor architecture (ARM Cortex-M3)
• Matching clock speed (166MHz)
• Identical memory configuration (512KB flash, 64KB RAM)
• Identical FPGA fabric size (90K logic modules)
• Identical package specification (325-FCBGA, 11x14.6mm)
• Identical I/O count (180 pins)
• Identical operating temperature range (-40°C to 100°C)
• Identical peripheral set (DDR, PCIe, SERDES, CANbus, Ethernet, I2C, SPI, UART/USART, USB)
• Same series designation (SmartFusion2)
• Identical compliance status (RoHS non-compliant, REACH Unaffected)

The substitution is based on electrical and mechanical parameter equivalence. The suffix variation (FCS vs. T-FCS) represents a manufacturing or temperature grade variant within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both the M2S090-FCS325I and M2S090T-FCS325I are active production devices from Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability: M2S090T-FCS325I has higher stock (1011 units vs. 896 units)
• Supply chain lead times and procurement timelines
• Compliance requirements: Both parts share identical RoHS non-compliant and REACH Unaffected status
• Moisture sensitivity handling: Both require MSL 3 precautions (168-hour floor life)

No functional or performance differences exist between these variants. PCB layout, firmware, and system design remain unchanged when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can M2S090T-FCS325I be used as a direct replacement for M2S090-FCS325I?

A: Yes. Both parts are electrically and mechanically identical. They share the same processor core, clock speed, memory configuration, FPGA fabric size, package type, pin count, and operating temperature range. No design modifications are required.

Q: What does the "T" suffix in M2S090T-FCS325I indicate?

A: The suffix represents a manufacturing or temperature grade variant within the SmartFusion2 product family. Both variants maintain identical electrical specifications and operating temperature ranges (-40°C to 100°C).

Q: Are there any package or pinout differences?

A: No. Both parts use the 325-FCBGA package with 11x14.6mm dimensions and 180 I/O pins. Pinout and package footprint are identical.

Q: Do these parts have different compliance certifications?

A: No. Both parts share identical RoHS non-compliant and REACH Unaffected status. Compliance handling and documentation requirements are the same.

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

A: Both parts are classified as MSL 3 with a 168-hour floor life. Identical moisture control and storage procedures apply to both variants.

Q: Are there inventory or lead time considerations?

A: M2S090T-FCS325I currently has higher inventory (1011 units) compared to M2S090-FCS325I (896 units). Availability may influence procurement decisions based on project timelines.
