M2S090-FCSG325

Soc System On Chip Overview

The M2S090-FCSG325 is a SmartFusion2 System-on-Chip FPGA from Microchip Technology, integrating an ARM Cortex-M3 processor with a 4-input LUT-based FPGA fabric. It features 86K logic elements and operates at a maximum clock frequency of 166 MHz. The device includes 512 kB of program memory and 64 kB of data RAM. Electrical specifications require a core supply voltage (VDD) of 1.2 V typical, with I/O banks supporting voltages from 1.2 V to 3.3 V. The component is housed in a 325-FCBGA package.

Soc System On Chip Procurement Notes

Verify the specific speed grade suffix (e.g., -1) required for timing closure, as the base model number may not specify performance tier. Confirm thermal management requirements based on junction-to-air resistance values provided in the datasheet for the FCS325 package under intended airflow conditions. Ensure power supply sequencing adheres to the monotonic ramp requirements specified for VDD and VPP.

Soc System On Chip Selection Notes

Select this device when a combination of embedded processing and reconfigurable logic is needed within a single chip. Compare against IGLOO2 series if only FPGA fabric is required without the MSS. Verify that the 325-ball BGA footprint fits the PCB layout constraints. Check if the 166 MHz operating speed meets the system timing requirements or if a higher speed grade is necessary.

Soc System On Chip Part Context

This part belongs to the SmartFusion2 family, which bridges the gap between traditional MCUs and FPGAs. It shares the same underlying flash technology and I/O architecture as the IGLOO2 FPGA family but adds the hard ARM Cortex-M3 core. The M2S090 density sits in the mid-range of the SmartFusion2 portfolio, offering significant logic resources compared to the smaller M2S005/M2S010 variants.

Soc System On Chip Replacement Considerations

Direct pin-compatible replacements within the same package are limited to other densities in the SmartFusion2 series (e.g., M2S060, M2S150) if logic capacity differs. Cross-family migration to IGLOO2 requires removing the MSS functionality. Always verify updated errata documents for any silicon revisions affecting timing or electrical characteristics.
