440 macrocells, instant-on, industrial temp — right-sized glue logic
The Intel EPM570T100I5N is a MAX® II CPLD with 440 macrocells and 570 logic elements — enough density to absorb a board full of 74-series logic or handle power-up sequencing, bus arbitration, and address decoding without reaching for an SRAM-based FPGA that needs a configuration load. It is in-system programmable via JTAG, so the logic image stays in the non-volatile flash cells and the device is operational the instant power rails are stable — do you really need an FPGA for that? The 5.4 ns pin-to-pin propagation delay (tpd1 max) sets the combinational throughput ceiling — for registered logic the internal clock-to-output path is faster, but for purely combinatorial paths this is the figure that governs setup timing at the receiving flip-flop.
Dual supply, industrial temperature, active lifecycle
The 100-TQFP tray packaging means it ships in the standard anti-static tray; moisture sensitivity level is typically MSL 3 for this package family, so a bake before reflow is required if the floor life is exceeded.
Sourcing and procurement — active, quoted to order
If your board sees a cold start below freezing or sits near a heat source, the I5N is the correct BOM line.
