440 macrocells, 5.4 ns pin-to-pin — the glue-logic gate count and speed
The Intel EPM570T144I5N is a MAX® II CPLD with 440 macrocells, organised as 570 logic elements. The 5.4 ns propagation delay (tpd1) is the pin-to-pin combinational path — it sets the ceiling for address decoding, state-machine clocking, or bus-interface logic that must settle within one cycle of a 180-MHz synchronous domain. In-system programmable via JTAG, so it programs on the assembled board without a separate socket adapter — useful for prototype spins and field-updateable glue logic where a mask-change is not an option.
Industrial temperature range and dual-voltage supply
The -40°C to 100°C junction-temperature range qualifies this part for outdoor telecom cabinets, engine-bay controllers, and factory-floor I/O modules where the ambient hits 85°C and the die runs hotter. The 116 user I/O are available on the 144-TQFP (20×20 mm) package. The 0.5 mm pitch demands a four-layer PCB for clean fan-out of the outer rows; a two-layer board can break out only the perimeter pins.
