The EP3C40F780C6N is a Cyclone III FPGA from Altera (now Intel) featuring 39,600 logic elements, 1,161,216 bits of embedded memory (126 M9K blocks), 126 embedded 18×18 multipliers, and 4 PLLs. It provides up to 535 user I\/Os in a 780-pin FBGA package, supporting LVDS, LVPECL, SSTL, HSTL, and other differential and single-ended I\/O standards. Built on TSMC 65nm low-power process technology, the device operates at 1.2V core voltage with commercial temperature range (0 to 85\u00b0C). It supports DDR2 SDRAM and QDRII+ SRAM external memory interfaces. Speed grade 6. Status: NRND (Not Recommended for New Designs).<\/p>","protected":false},"excerpt":{"rendered":"

Each LE consists of a 4-input look-up table (LUT), a programmable register, and carry chain logic. The 39,600 LEs are organized into 2,475 LABs. Interconnect routing allows signals to flow between any LABs and I\/O elements. M9K embedded memory blocks can be configured as RAM, FIFO, or ROM in various width-depth combinations. Embedded 18x18 multipliers support DSP operations. Four PLLs provide clock synthesis, phase shifting, and jitter filtering with up to 20 global clock networks. Configuration is loaded via JTAG, AS, or PS mode into SRAM cells that define the logic function.","pin_description":"
