FLEX 8000 FPGA — 1296 logic elements, 181 I/O, 5V supply
The Altera EPF81500AQC240-3 is a FLEX 8000 series FPGA with 1296 logic elements and 16000 usable gates, packaged in a 240-pin BFQFP (32x32 mm PQFP).
1296 logic elements — sizing the logic budget
With 1296 logic elements and 162 LABs/CLBs, this part fits glue logic, state machines, and moderate data-path functions — think address decoding, bus arbitration, or a simple UART wrapper. It is not sized for a soft-core processor or a video scaler; the 16000-gate ceiling sets a hard bound on combinatorial depth.
There is no last-time-buy window or NRND flag on this line. Note the RoHS non-compliant marking — this part uses leaded solder balls and is not exempt for new EU RoHS designs unless a specific exemption applies. For legacy repair or military/industrial contracts that permit tin-lead, this is the correct original-spec part.
