- 12.7 Gbps SERDES transceivers with PCIe Gen2 and SGMII support
- 484-pin FCBGA package with 244 user I/O pins

- Industrial-grade temperature range: –40°C to +85°C
The ACTEL MPF300T-1FCG484I is a PolarFire family FPGA from Microsemi / Microchip, delivering 300,000 logic elements at speed grade -1 in a compact 484-pin FCBGA package. The "-1" suffix guarantees higher performance headroom than the standard speed grade variant, making it the preferred choice for timing-critical designs operating close to the device's maximum frequency ceiling. Built on a 28nm nonvolatile flash process, it combines high logic density, 12.7 Gbps transceiver capability, and DPA-resistant security — all without requiring an external configuration memory or boot device.
For engineers evaluating the MPF300T family, the FCG484 package is the smallest footprint available for the MPF300T density — a practical consideration for board layouts where space is constrained but full PolarFire logic capacity is still required. With 244 user I/O pins, it covers the majority of mid-range embedded designs without the added PCB complexity of a larger package. The power advantage over SRAM-based alternatives is real and measurable: up to 50% lower static power means less thermal management overhead in deployed systems, which matters particularly in enclosed or passively cooled military and industrial enclosures.
Related Products For Your Business
For procurement teams and engineers sourcing the ACTEL MPF300T-1FCG484I, the “-1” speed grade is often the deciding factor between this variant and the standard MPF300T-FCG484. Both carry the same 300K logic element die in the same 484-pin FCBGA footprint — the -1 suffix means the device has been tested and guaranteed to meet higher performance thresholds, giving timing-critical designs the margin they need without moving to a larger or more expensive package. We carry verified MPF300T-1FCG484I inventory with full traceability and can support both evaluation quantities and production orders with rapid response.
MPF300T-1FCG484I: PolarFire Architecture and Power Advantage
The PolarFire flash architecture that underlies the MPF300T-1FCG484I was purpose-built to address the two most common complaints about mid-range SRAM FPGAs: power consumption and security vulnerability. At 28nm with a 1.0V core, the static power footprint is roughly one-tenth that of competing SRAM devices at similar density — a difference that compounds significantly in deployed systems running continuously. The nonvolatile configuration eliminates the external SPI flash that SRAM FPGAs require for boot, removing both a bill-of-materials component and a potential security attack surface. DPA-resistant 256-bit AES and SHA-256 authentication are hardened into the silicon, not implemented in soft IP.
MPF300T-1FCG484I vs MPF300T-FCSG536I: Package Selection Guide
Engineers comparing the MPF300T-1FCG484I against the FCSG536 package variant will find the same PolarFire MPF300T die in both — the difference is purely in package size and I/O availability. The FCG484 provides 244 user I/O pins in a smaller footprint; the FCSG536 opens up to 284 I/Os for designs that need the additional headroom. Both support the same SERDES transceivers, PCIe Gen2, and security features. Package selection typically comes down to board space constraints and I/O count requirements rather than any functional difference between the two.

Frequently Asked Questions (FAQ)
What Is the Difference Between the MPF300T-1FCG484I and the MPF300T-FCG484I?
The two variants are identical in die, package, I/O count, and features. The “-1” suffix denotes a higher speed grade — the device has been characterized and guaranteed to meet tighter timing parameters at maximum frequency. For designs with margin to spare at the standard speed grade, the standard variant is sufficient. For timing-critical implementations, the -1 grade provides the additional headroom.
How Does the MPF300T-1FCG484I Compare to the MPF300T-FCSG536I?
Both use the same PolarFire MPF300T die. The FCG484 package is smaller with 244 user I/O pins; the FCSG536 provides 284 I/Os in a slightly larger footprint. Choose the FCG484 when board space is the primary constraint and 244 I/Os are sufficient; move to the FCSG536 when more I/O bandwidth is needed.
Does the MPF300T-1FCG484I Require an External Boot Device?
No. The PolarFire flash architecture retains configuration permanently through power cycles without an external SPI flash or PROM. The device is instant-on at power-up with no boot sequence vulnerability.
Is the MPF300T-1FCG484I SEU Immune?
Yes. The nonvolatile flash configuration cannot be corrupted by single-event upsets, unlike SRAM-based FPGAs that require periodic configuration scrubbing in radiation environments. This makes the MPF300T-1FCG484I well suited for avionics and defense applications where SEU tolerance is a qualification requirement.
