Highlighted values are higher. LUT counts are shown as published; the LUT4 equivalent is an approximation to compare different LUT types, see how FPGA vendors count logic. Add up to two more devices to this comparison.

Key differences

The M2S050 has about 77% more logic capacity (56.3K vs 31.8K LUT4 equivalents).

They use different logic architectures: the 5CSXC4 is built from ALMs and the M2S050 from LUT4, so the raw LUT counts (15.9K vs 56.3K) are not directly comparable.

For arithmetic, the 5CSXC4 has 84 variable-precision DSP blocks against 72 18×18 math blocks (MACC) on the M2S050.

The 5CSXC4 has more on-chip memory (2.6 Mb vs 1.2 Mb).

Both have transceivers: 6 at up to 3.125 Gb/s on the 5CSXC4 and 8 at up to 5 Gb/s on the M2S050.

Configuration memory: sram on the 5CSXC4, non-volatile (flash) on the M2S050.

The 5CSXC4 is designed with Altera Quartus Prime and the M2S050 with Microchip Libero SoC.
