Soc System On Chip Procurement Notes

Verify RoHS compliance status as documentation indicates variations across production lots; some sources list the component as non-compliant while others specify compliance. Confirm the specific suffix 'I' denotes industrial temperature range operation (-40°C to 100°C). Check current manufacturing lifecycle status and lead times directly with Microchip Technology or authorized distributors, as availability fluctuates.

Soc System On Chip Selection Notes

Select this model when a balance between processor performance and moderate FPGA capacity is required. The 288-pin package offers sufficient I/O for complex peripheral integration. Ensure design requirements align with the 80 MHz maximum operating frequency and available memory sizes. Compare against the A2F500M3F variant if higher speed grades or different packaging options are necessary for the target application.

Soc System On Chip Part Context

This component belongs to the SmartFusion family, which bridges the gap between traditional MCUs and FPGAs by combining them into a single silicon die. It utilizes Microsemi's (now Microchip) proven ProASIC3 technology for the FPGA portion, offering radiation tolerance and nonvolatile configuration. The series is designed for applications demanding security, low power, and system-level integration.

Soc System On Chip Replacement Considerations

Direct pin-to-pin replacements within the same package may include other variants in the A2F500M3 series, such as the A2F500M3F-CS288I, depending on speed grade and memory configuration requirements. Verify that any substitute maintains compatibility with the existing firmware and hardware constraints regarding voltage levels and thermal dissipation.
