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
Both devices offer similar logic capacity: 264K and 254K LUT4 equivalents.
They use different logic architectures: the 5ASXB3 is built from ALMs and the MPFS250T from LUT4, so the raw LUT counts (132K vs 254K) are not directly comparable.
For arithmetic, the 5ASXB3 has 809 variable-precision DSP blocks against 784 18×18 math blocks (MACC) on the MPFS250T.
Both have transceivers: 30 at up to 6.5536 Gb/s on the 5ASXB3 and 16 at up to 12.5 Gb/s on the MPFS250T.
Configuration memory: sram on the 5ASXB3, non-volatile (sonos flash) on the MPFS250T.
The 5ASXB3 is designed with Altera Quartus Prime and the MPFS250T with Microchip Libero SoC.
