Logic fabric and I/O budget for a 33K-cell design
The XC7A35T-2CPG236C is an AMD Artix-7 FPGA with 33,280 logic cells organized into 2,600 CLB slices — enough fabric for a mid-density glue-logic or DSP-intensive design that needs roughly 26,000 LUTs and leaves margin for a few iterations before the floorplan tightens. Its 106 user I/O, packed into a 238-ball CSBGA on a 10x10 mm substrate, serve designs where the peripheral count is constrained by the package footprint rather than the core logic — think sensor fusion, camera interface, or a modest parallel bus.
On-chip memory and supply tolerance
1,843,200 total RAM bits (1.8 Mbit) of block RAM give the fabric roughly 180 KB of distributed storage — enough for a few frame buffers at VGA resolution or a modest FIFO chain without reaching for external SRAM. The core supply rail is tight at 0.95 V to 1.05 V — the regulator must hold 1.0 V ±50 mV under load transients, so a standard 1.0 V LDO with 1% accuracy and enough headroom for the dropout is the safe call. Commercial temperature grade (0°C to 85°C junction) suits controlled indoor environments — a fanless enclosure with moderate airflow keeps the junction below the ceiling when the design is clocking 200+ MHz across the fabric.
ROHS3 compliant — the 238-CSBGA package uses lead-free solder balls and halogen-free mold compound, meeting the current EU restriction scope without an exemption.
