The in-system programmable flash allows in-circuit logic rework during development or field updates.
The 5.4 ns propagation delay is the time from a registered input pin to a combinatorial output. In a typical address-decode path, that buys enough margin to run a bus without adding wait states.
The suffix 'I' indicates the industrial temperature range (-40°C to 100°C), while 'C' denotes commercial (0°C to 70°C). The rest of the logic — 570 logic elements, 440 macrocells, 116 I/O, 5.4 ns tpd — is identical.
Yes, the EPM570GT144I5 is a direct pin-compatible replacement for the EPM570T144C5 in the same 144-TQFP package, with the same logic density and speed grade. The only difference is the wider temperature range on the 'I' variant.
