  • Standard industrial variant with broadest distributor availability (vs EP1K100EFI484-2)

Design Notes

The 484-ball FineLine BGA package requires careful PCB layout: escape routing on inner layers with via-in-pad or dog-bone fanouts, and a continuous ground plane beneath the BGA to control impedance and reduce SSN. Use the ACEX-1K family datasheet's recommended land pattern and follow IPC-7351 naming conventions. Provide at least one 0.1 uF + 10 uF decoupling capacitor pair per VCCINT/VCCIO power pin pair, placed as close to the balls as the breakout allows. Add bulk capacitance on the 2.5 V core rail to handle inrush during configuration.

Do not confuse temperature grade suffixes: 'I' (Industrial -40C to +85C), 'C' (Commercial 0C to +85C), 'E' (Enhanced industrial). All variants share the same pinout in the 484-FBGA package, so PCB compatibility is preserved, but operating temperature must match the deployment environment. Also note that the ACEX-1K family uses MAX+PLUS II or Quartus II (legacy) toolchains; modern Quartus versions may not support ACEX-1K, requiring the legacy MAX+PLUS II software for bitstream generation.

Estimated: at 250 MHz toggle rate with 60-70% utilization, the EP1K100FI484-2 can consume 1-2 W from the 2.5 V core rail (estimate based on ACEX-1K family typical power). Use Quartus II PowerPlay to estimate actual dissipation for your design; derate the FBGA thermal resistance (~20 C/W theta-JA typical for 484-FBGA) and ensure the design includes adequate copper thermal vias under the package. Add a heatsink if the design targets industrial temperature extremes with high toggle rates.

Route configuration signals (nCONFIG, nSTATUS, CONF_DONE, DCLK) carefully and keep them short; these signals are susceptible to noise and must be pulled up correctly per the ACEX-1K family datasheet. JTAG (TCK, TMS, TDI, TDO) traces should be length-matched and guarded by ground to maintain signal integrity during in-system programming. The MSEL[0..2] pins select the configuration mode and must be tied to the correct logic levels for the chosen configuration scheme (AS, AP, PS, JTAG).
