FPGA / CPLD & Programmable Logic

About FPGA / CPLD & Programmable Logic

When a microcontroller is too slow and an ASIC is too rigid, an FPGA or CPLD fills the gap with reconfigurable logic that can be rewritten in the field. SRAM-based FPGAs from AMD (Xilinx) and Intel (Altera) handle high-density signal processing, while flash-based FPGAs and CPLDs from Lattice and Microchip cover low-power glue-logic and I/O expansion. Selection pivots on logic element count, I/O count, speed grade, package footprint, and configuration memory type. Verify device status (active versus NRND), download datasheets, and request BOM quotes.
