IGLOO AGL250V5-FGG144 — 250K-gate FPGA for low-power glue logic
The Microsemi AGL250V5-FGG144 is a nonvolatile flash-based FPGA from the IGLOO series, offering 250000 gates and 6144 logic elements in a 144-ball FPBGA package. It provides 97 user I/O and 36864 bits of total RAM, operating from a 1.5 V core supply (1.425 V to 1.575 V range).
1.5 V supply — tight regulation needed
The core supply tolerance of 1.425 V to 1.575 V means the 1.5 V rail regulator must hold within ±75 mV under load transients. A standard 1.5 V LDO with ±2% accuracy and 50 mV dropout margin works, but a switching regulator needs careful output capacitor selection to keep ripple below 30 mV peak-to-peak. Confirm the regulator's load regulation spec against the FPGA's dynamic current draw — the IGLOO family's flash-based architecture draws lower static power than SRAM FPGAs, but I/O bank switching can still create fast current steps.
97 I/O in a 144-ball BGA — routing the board
The 144-FPBGA (13x13 mm) package with 97 user I/O leaves 47 balls for power and ground, giving good signal integrity for a 1.5 V core design. The ball pitch is 1.0 mm, which routes cleanly on a 4-layer board with 0.2 mm trace widths and 0.3 mm via pads. The I/O banks support multiple voltage standards, but the commercial temperature range limits use to environments where ambient stays below 70°C — no under-hood or outdoor cabinet deployment without active cooling.
The part is ROHS3 compliant. Stock this part with confidence for designs that will run for the next several years, but store the reels in a dry cabinet: the 144-FPBGA is MSL 3, so bake before reflow if the moisture barrier bag has been open past the floor-life window.
