A2F500M3G-1CSG288

Soc System On Chip Overview

The A2F500M3G-1CSG288 is a SmartFusion customizable System-on-Chip (cSoC) integrating an ARM Cortex-M3 processor with ProASIC3 FPGA fabric. It features 11,520 logic cells and 500,000 equivalent gates within a 288-pin CSPBGA package. The device includes up to 512 Kbytes of embedded nonvolatile flash memory (eNVM) and 64 Kbytes of embedded SRAM (eSRAM). Key peripherals include a 10/100 Ethernet MAC, external memory controllers, I2C, SPI, and UART interfaces. Operating frequencies reach 80 MHz to 100 MHz depending on the specific variant configuration.

Soc System On Chip Procurement Notes

Verify the suffix '1' indicates specific speed grade or manufacturing revision against official Microchip documentation. Confirm RoHS compliance status as some variants may differ. Check for active production status and lead times directly with authorized distributors. Ensure ESD handling procedures are followed due to CMOS technology sensitivity.

Soc System On Chip Selection Notes

Select this model when both deterministic real-time processing via the Cortex-M3 and flexible hardware acceleration via the FPGA fabric are required. Compare eNVM capacity requirements; ensure 512 Kbytes suffices for firmware storage. Verify pin count compatibility with the 288-pin CSPBGA footprint. Consider thermal dissipation capabilities for the plastic epoxy package in enclosed enclosures.

Soc System On Chip Part Context

This component belongs to the Microchip SmartFusion family, bridging the gap between traditional MCUs and FPGAs. It succeeds earlier Actel SmartFusion products following Microchip's acquisition. The part utilizes proven ProASIC3 flash-based FPGA technology, offering non-volatile configuration without external boot devices.

Soc System On Chip Replacement Considerations

Direct substitutes include other A2F500 series variants with different packages like CSG288 or FG256 if pinout compatibility allows. Cross-reference with Microsemi legacy part numbers if migrating from older Actel designs. Verify functional equivalence of the MSS peripherals before substitution.
