Logic density and I/O for mid-range designs
The XC6SLX25-2FTG256I belongs to the Spartan®-6 LX family, a mid-density FPGA series balancing logic fabric, block RAM, and I/O count for cost-sensitive applications. With 24,051 logic cells and 1,879 LABs/CLBs, it fits control logic, data-path processing, and interface bridging in a single device. The 186 user I/O pins, accessed through the 256-ball FTBGA package, provide enough connectivity for parallel buses, DDR memory interfaces, and multi-channel sensor inputs without needing a larger footprint.
On-chip memory and supply rails
The 958,464 total RAM bits (block RAM) support FIFO buffers, line stores, and small look-up tables directly on the die, reducing off-chip memory access latency. The core supply voltage range of 1.14 V to 1.26 V aligns with standard 1.2 V FPGA rails, simplifying the power tree design.
Supplied in tray packaging, the device is suited for hand-loading during prototype runs or low-volume production without the minimum-order constraints of tape-and-reel.
Lifecycle and compliance posture
It is fully ROHS3 compliant, meeting the EU directive for lead-free and restricted-substance content.
