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.
