The C5 suffix typically indicates a slower speed grade. The C4 carries a 5.4 ns tpd(1) max; the C5 would be slower. Confirm the exact C5 timing in its datasheet before substituting.
Yes, the device is In System Programmable via the JTAG interface. Any standard JTAG cable (USB-Blaster, etc.) that supports the MAX II family will work.
The 144-TQFP pinout is documented in the Intel MAX II datasheet. The base product number EPM570 shares the same pinout across the density variants in the same package.
No official replacement has been announced while the part is Active. If an EOL notice appears, Intel typically recommends the next-density MAX II or MAX 10 device — check the PCN for the exact pin-compatible substitute.
