The 144-LQFP package has a 20×20 mm body. The 0°C to 85°C junction temperature range covers commercial and most industrial indoor environments.
The EPM1270GT144C3N comes in a 144-LQFP package, also specified as a 144-TQFP with a 20×20 mm body. It is a surface-mount package with 116 usable I/O pins.
The C3N and C4N suffixes typically indicate different speed grades within the same MAX II density. The C3N carries a 6.2 ns tpd; the C4N would be a slower speed grade. Verify the exact tpd for the C4N from its datasheet before substituting.
Yes, if the design's timing closure can tolerate the C3N's 6.2 ns tpd — the C4N is a slower grade, so the C3N is a drop-in replacement with faster timing. The pinout, package, and logic density are identical.
