DEVICE & PACKAGE DECISION
Check the -8L core-rail conditions before a standard-grade substitution
The F17 industrial -8L row should be considered with its sourced core-voltage range, timing designation and connection budget together. A standard -7 industrial family comparison is not a rail-equivalent substitute. Compare F23 or F29 only after checking whether their changed core, package and power conditions suit the board.
Engineering screening guidance using reviewed catalogue evidence. Examples are hypothetical and advisory; validate your actual design and the exact ordering code.
Result: 25 I/O remain in the count-only budget (83.7% allocated).
Planning diagram: assumed I/O allocation 128 I/O assumed allocation / 153 documented package I/O; 25 I/O unallocated. Count-only planning diagram, not a pinout or bank assignment.
83.7% of the sourced package count allocated; 25 I/O unallocated.
Each signal consumes one single-ended user I/O in this example. Dedicated serial lanes are separate. Bank voltage, differential pairing, clocks, configuration use and actual pin allocation can reduce usable capacity. Reserved signals here are an assumed design allowance, not manufacturer-reserved pins.
Result: Allocate at least 65,536 payload bits before adding memory overhead. The current reviewed embedded-memory reference is 594 Kb.
Payload arithmetic only. The source Kb/kb unit is retained; this example does not choose a decimal/binary conversion or claim a percentage fit. Round each buffer to the native memory-block geometry and check port width, depth, ECC/parity, dual-port use and implementation reports.

Can I reuse a standard -7 core rail for this -8L code?
Compare the sourced recommended core-voltage ranges in the table and the applicable handbook conditions. A matching industrial temperature grade does not make the supply requirements equal; validate all rails and sequencing.
What does the numerical example establish for EP4CE22F17I8LN?
It establishes arithmetic under the explicitly hypothetical inputs shown here. It is not a tool result, synthesis report, timing closure, pin-assignment validation or application qualification. Replace the assumptions with your signal list and memory geometry, then validate in the vendor tools.
For software-heavy control with limited parallel I/O, assess an MCU or processor against the same latency, interface and power requirements. For wide parallel datapaths or custom timing, compare FPGA architectures using a mapped design. For early prototyping, an evaluation board may reduce initial hardware work; verify its exact device, accessible interfaces and production suitability.
Start with this package’s I/O, block RAM and serial channel counts, or enter your actual requirements. Native resource requirements apply only to the selected architecture.
292 full MPNs meet the entered numeric constraints. Showing 6 device representatives, at most two per manufacturer, ordered by smallest excess resources. Temperature and package variants still need selection.
Different family or manufacturer: review native logic/DSP architecture, HDL/IP portability and toolchain.
Package: F17 → FBG484. Verify the applicable limits and design impact.
Temperature grade: I → Commercial (C). Verify the applicable limits and design impact.
Speed grade: -8L → -1. Verify the applicable limits and design impact.
Numeric matches do not establish pin compatibility, protocol support, lifecycle or supply availability.
Numeric screening is not replacement approval.
Logic and DSP mapping, pinout, bank voltages, temperature, timing, protocol support and toolchain remain engineering checks. Serial channel quantity does not verify data rate or protocol support. Cross-brand candidates generally require board and HDL review.
