Part number guide
How to read a Microchip (Microsemi) FPGA part number
Microchip (formerly Microsemi, and Actel before that) builds its FPGA ordering codes the same way across PolarFire, IGLOO2, SmartFusion2 and the older flash families: device, optional speed grade, package letters, a G for RoHS, the ball or lead count, and the temperature grade last.
The fields below are taken from Microchip's own ordering-information figures for PolarFire and ProASIC3 nano.
Anatomy of an ordering code
MPF300T-1FCG1152I — a 300K logic-element PolarFire with transceivers, -1 speed grade, in a 1,152-ball flip-chip BGA, industrial temperature.

IGLOO, ProASIC3 and their variants use the same order of fields. Here the temperature field is blank for commercial.

Worked examples
| MPF300T | PolarFire, 300K logic elements, design security with transceivers |
| 1 | Speed grade -1, up to 15% faster than standard |
| FC | Flip chip, 1.0 mm pitch |
| G | RoHS plating |
| 1152 | 1,152 balls |
| I | Industrial (TJ −40 °C to 100 °C) |
The feature letters after the density are part of the device: MPF300T, MPF300TS and MPF300TL are the same logic with different security and power options.
| MPF100T | PolarFire, design security with transceivers |
| (blank) | Standard speed grade |
| FCV | Flip chip, 0.8 mm pitch |
| G | RoHS plating |
| 484 | 484 balls |
| E | Extended commercial (TJ 0 °C to 100 °C) |
No speed digit means the standard grade, not a missing field. And E here is extended commercial — not industrial, which is I.
| MPF200T | PolarFire, design security with transceivers |
| FCS | Flip chip, 0.5 mm pitch |
| G | RoHS plating |
| 325 | 325 balls |
| I | Industrial |
FC, FCV and FCS are the same flip-chip construction at 1.0, 0.8 and 0.5 mm ball pitch. The pitch decides the PCB, so they are not interchangeable.
| A3PN250 | ProASIC3 nano, 250,000 system gates |
| (blank) | Standard speed grade |
| VQ | Very thin quad flat pack, 0.5 mm pitch |
| G | RoHS-compliant packaging |
| 100 | 100 leads |
| I | Industrial (−40 °C to 100 °C junction) |
On the older flash families a blank temperature field means commercial. Only the industrial part carries a letter.
What the part number does not tell you
- Usable I/O. The pin or ball count is the whole package. User I/O is always lower and differs between devices in the same package.
- Lifecycle status. Nothing in an ordering code says whether a part is active, not recommended for new designs, or discontinued. That comes from the manufacturer's product change notices.
- Whether it was ever built. A code can be perfectly well formed and describe a combination that was never offered. Valid syntax is not evidence of a real part.
- Date code or revision. Not encoded. If a build needs a specific one, state it on the order.
Check a specific part
Every part page carries the specifications and package details for that exact code. Search a part number, or send one for stock and pricing — including obsolete and end-of-life devices.
