The LFXP2-8E-5TN144I provides 8000 LUT4 units, 18 blocks of 9Kbit embedded block RAM, and 8 hardware DSP blocks with 18x18 multipliers. The on-chip Flash enables instant-on operation without an external configuration device, and provides excellent design security. The -5 speed grade offers the fastest timing performance in the XP2 family.","working_principle":"The LFXP2 architecture consists of a programmable logic fabric built from PFU (Programmable Functional Unit) blocks, each containing four 4-input LUTs, dedicated carry logic, and wide gating functions. The PFU blocks can implement combinatorial logic, distributed RAM, or shift registers. The EBR (Embedded Block RAM) provides dedicated 9Kbit dual-port SRAM blocks for larger storage needs. The DSP blocks contain 18x18 hardware multipliers with accumulator logic for efficient DSP algorithm implementation. The on-chip Flash stores the configuration bitstream and transfers it to the SRAM configuration cells during power-up, enabling instant-on operation.","pin_description":"
