MPF100T-FCG484E is a nonvolatile PolarFire FPGA from Microchip. For a purchase or schematic release, three details need to stay attached to the full ordering code: its standard speed grade, its 484-ball package and its extended-commercial junction-temperature grade. A family headline such as “12.7 Gbps” does not describe every speed grade.
Engineering reference updated October 19, 2026. Device-document revision dates identify the references used; they do not identify the first shipment date of an orderable part.
Read the complete ordering number
The manufacturer's ordering appendix lists MPF100T-FCG484E. MPF100T identifies the density and transceiver device; FCG484 selects the RoHS-compliant 484-ball flip-chip BGA; E specifies extended commercial operation with a junction-temperature range of 0°C to +100°C. The code has no -1 speed prefix, so it selects STD, the standard speed grade. The ambient-temperature range of a finished assembly must be derived from its power and thermal design rather than copied from the junction rating.
Keep the complete string on the BOM and quotation. Adding -1, changing E to I, or adding an S feature suffix changes the requested device option. In particular, design-protection features on a T device do not establish that it contains the user cryptographic coprocessor offered on TS/TLS devices.
Resources and package connectivity
| MPF100T-FCG484E item | Manufacturer specification |
|---|---|
| Logic density | 109K logic elements, using the rounded figure in the product overview |
| Arithmetic | 336 dedicated 18 × 18 math blocks |
| Large SRAM | 352 blocks of 20 Kbit each |
| Micro SRAM | 1,008 blocks of 64 × 12 bits; overview total RAM: 7.6 Mbit |
| Package user I/O | 244 total: 96 HSIO and 148 GPIO |
| Serial connectivity | 8 transceiver lanes in this package |
| Package geometry | 484-ball FCG484; 23 × 23 mm body; 1.0 mm ball pitch |
| Temperature / speed | E: 0°C to +100°C operating junction temperature; STD speed grade |
These are resource and package counts, not a completed implementation. A memory's legal width, depth, port mode and error-correction requirements determine usable storage. An arithmetic pipeline also needs registers, routing and a clock that meets timing. Do not compare 109K logic elements with another architecture's differently defined logic-cell metric as if the counts were interchangeable.
The 244 user I/O count excludes the power, ground and other dedicated balls in the package. HSIO and GPIO have different capabilities. Create a pin worksheet from Microchip's exact MPF100T/FCG484 pin table and the selected Libero device: include ball, bank, direction, I/O standard, supply, clock or differential-pair role, and any shared programming function. A generic 484-ball footprint is insufficient to establish electrical compatibility.
Use the standard-speed serial limits
Datasheet Table 5-35 specifies 0.25–10.3125 Gbps for STD transmitter operation and AC-coupled receiver operation. The 12.7 Gbps upper figure applies to -1 speed grade. DC-coupled receiver operation has a separate 0.25–3.2 Gbps range. Check the coupling mode, channel conditions, reference clock, supply setting and the complete electrical table before choosing a line rate; the headline rate alone is not a link-compliance result.
The family provides two hardened PCIe Gen1/Gen2 controllers, each configurable for ×1, ×2 or ×4. They are not a single ×8 controller. A SERDES capable of a given line rate does not supply every protocol's controller, MAC, PCS or system software. Ethernet, converter links and PCIe each need the appropriate IP, lane assignment, clock plan and verification.
Power, startup and programming
Datasheet Table 4-2 lists VDD core and VDDA transceiver supplies with nominal 1.0 V or 1.05 V operating modes. Each setting is independently selectable and is not dynamically adjustable. For VDD, the recommended ranges are 0.97–1.03 V in 1.0 V mode and 1.02–1.08 V in 1.05 V mode. VDD18 is nominally 1.8 V and VDD25 is nominally 2.5 V. Bank VDDI must follow the chosen bank type and I/O standard; these nominal values do not replace the complete rail tolerances and conditions.
Build the power tree from the recommended-operating-conditions table and the exact package pinout. Include the core, transceiver and dedicated supplies as well as every bank supply used by the design. Select regulator current, transient response, filtering and decoupling from an implementation-based estimate and a board power-integrity analysis. A single core-voltage number is not a complete power specification, and “nonvolatile” does not mean zero supply current at startup.
The programmed fabric configuration is retained without an external configuration PROM. User operation still waits for the specified power-up and initialization sequence. Initialization data may come from µPROM, sNVM or external SPI memory, depending on the design. External flash can therefore be part of a memory-initialization or update architecture, but it is not universally required just to retain the fabric configuration. Choose its capacity and supported programming flow from the generated design rather than a generic flash-size recommendation.
What procurement should request
Provide the exact ordering number, quantity, required date, packaging preference and any documentation or inspection requirements when requesting a quotation. Obtain written confirmation of the offered code, condition, traceability documents and commercial terms. This technical reference does not establish stock, price, delivery, manufacturer authorization or a certification for the finished system.
For an alternative, use the MPF100T replacement-qualification guide and compare the actual package pin tables, rails, features and timing. A shared family or ball count is only an initial screening condition.
Questions before releasing the BOM
Is E the industrial temperature grade?
No. E denotes extended commercial, with 0°C to +100°C operating junction temperature. Check the manufacturer's separate industrial ordering option if the requirement extends below 0°C. Neither suffix alone certifies an application.
Can this exact code run a 12.7 Gbps serial link?
Do not assign the -1 maximum to this STD part. Use the STD electrical limits, including the separate AC- and DC-coupled receiver conditions, and validate the implemented channel.
Does the FPGA provide a general data-encryption engine?
Do not infer the TS/TLS user cryptographic coprocessor from the non-S T ordering code. Define the security operation, required throughput, available IP and key-management design before selecting a device.
