A2F500M3G-PQ208I

Soc System On Chip Overview

The A2F500M3G-PQ208I is a SmartFusion customizable System-on-Chip (cSoC) FPGA manufactured by Microchip Technology. It integrates a hard ARM Cortex-M3 processor with flash-based FPGA fabric in a 208-pin PQFP package. The device features up to 512 Kbytes of embedded nonvolatile memory and SRAM, supporting multi-master access via an AHB matrix. Operating temperatures range from -40°C to +85°C, with supply voltages typically at 1.2V for the core and 1.8V/2.5V/3.3V for I/O.

Soc System On Chip Procurement Notes

Verify component authenticity through authorized Microchip distributors due to counterfeiting risks. Confirm RoHS compliance status as legacy variants may differ. Check for Process Change Notifications (PCNs) regarding assembly site changes or material updates. Ensure ESD handling protocols are followed during procurement and storage. Validate lead times as availability may fluctuate based on production cycles.

Soc System On Chip Selection Notes

Select this model when both deterministic MCU performance and reconfigurable logic are required in a single die. Compare eNVM capacity requirements against the 512 Kbyte maximum limit. Verify I/O voltage compatibility with the 1.8V, 2.5V, and 3.3V support levels. Consider thermal dissipation capabilities within the 208-PQFP package for high-load designs. Evaluate if the 100 MHz Cortex-M3 frequency meets system timing constraints.

Soc System On Chip Part Context

This part belongs to the SmartFusion family, bridging the gap between traditional MCUs and FPGAs. It succeeds earlier ProASIC3-based solutions by adding a hardened ARM core. The PQ208I suffix indicates the industrial temperature grade and 208-pin Quad Flat Package no-lead variant. It serves as a cost-effective alternative to separate MCU+FPGA combinations in space-constrained designs.

Soc System On Chip Replacement Considerations

Direct pin-to-pin replacements are limited within the same package. Consider the A2F500M3B series for similar functionality in BGA packages if footprint changes are acceptable. Review Microchip's product transition notices for end-of-life guidance. Alternative families like IGLOO2 or PolarFire may offer modern equivalents with updated features.
