The 6.2 ns pin-to-pin delay allows address decoding without wait states for devices with at least 6.2 ns setup time. The 980 macrocells provide enough logic for a decoder, counters, and glue logic.
No official successor has been announced for this density-speed grade.
Intel has not announced an official direct replacement for this density-speed grade. The EPM1270F256C4 remains active. For a smaller density alternative, the EPM240F100C5N offers 192 macrocells and a faster 4.7 ns tpd but only 80 I/O — it is not a pin-compatible substitute.
Use Quartus II software (version 9.1 or later) to compile the design and generate a.pof file. Connect a USB-Blaster or ByteBlaster II to the 10-pin JTAG header on the board, then use the Programmer tool to download the configuration.
The suffix 'C4' vs 'C5' indicates the speed grade. The C4 has a 6.2 ns maximum pin-to-pin delay (tpd1), while the C5 is a slower speed grade with a higher tpd. Both share the same 980 macrocells, 212 I/O, and 256-FBGA package. The C4 is the faster option for timing-critical paths.
The 'C4' suffix indicates the commercial temperature range (0°C to 85°C), while the 'I4' suffix is the industrial temperature range (-40°C to 100°C). Both share the same 6.2 ns tpd speed grade, 980 macrocells, and 212 I/O. The 'I4' variant is rated for outdoor or factory-floor environments where the commercial-grade part would not be reliable.
