ProASIC3 FPGA with 600K gates and 154 I/O
The Microchip A3P600-PQG208 is a nonvolatile flash-based FPGA from the ProASIC3 family, offering 600000 system gates and 110592 bits of embedded RAM in a 208-lead PQFP package (28x28 mm body). This part is typically used in glue-logic consolidation, interface bridging, and low-to-medium density logic integration where instant-on, single-chip operation is required — the flash configuration is live at power-up, no external boot memory needed.
Core supply and temperature grade — design constraints
The core supply range is tight: 1.425 V to 1.575 V. That means the regulator feeding the VCC rail needs ±2.5% accuracy or better, including load transient droop. A standard 1.5 V LDO with 1% initial tolerance and 50 mV dropout margin fits, but a switching regulator with 100 mV ripple eats the entire budget. If the design sees -40°C or 105°C ambient, step up to the ProASIC3 industrial-grade variant.
Package and footprint — PQFP-208 layout notes
The 208-BFQFP (PQFP-208) has a 28x28 mm body with 0.5 mm lead pitch. The footprint is standard for high-I/O-count QFP packages of this era — the layout engineer should match the land pattern to the supplier device package 208-PQFP (28x28) and verify the corner indexing. The package is surface-mount only; no exposed pad, so all thermal dissipation goes through the leads. For a 600K-gate design that toggles most of the fabric, add a low-velocity airflow or a heatsink if the ambient exceeds 70°C.
Lifecycle and compliance — active and ROHS3
If the design requires more than 110592 bits of RAM or a wider I/O count, the M2GL025-VFG256 (IGLOO2, 1.13 Mbits RAM, 138 I/O) is a functional cross-shop candidate — though it runs from a 1.14 V core and uses a different VQFP footprint.
