Digital ICs and FPGA sourcing guide: logic ICs, memory ICs, Xilinx Spartan/Artix/Kintex/Zynq, and Altera Cyclone/MAX/Arria FPGAs. ADD Components stocks digital ICs from TI, Xilinx (AMD), and Altera (Intel) with anti-counterfeit verification.
Digital ICs & FPGAs — Logic, Memory, and Programmable Hardware
Digital integrated circuits process binary signals — the 0s and 1s at the foundation of all computing. From basic logic gates to multi-million-gate FPGAs, digital ICs are the workhorses of data processing, storage, and configurable hardware.
ADD Components sources digital ICs and FPGAs from Xilinx (AMD), Altera (Intel), and Texas Instruments (TI) — covering logic families, memory, and programmable logic at every scale.
Digital IC Sub-Types
Logic ICs
Basic building blocks — AND, OR, NOT, NAND, NOR, XOR gates — plus flip-flops, latches, buffers, and line drivers. Available in TTL, CMOS, and LVDS families. Used in glue logic, signal routing, and interface bridging in virtually every PCB design.
Memory ICs
Volatile (SRAM, DRAM, DDR3/DDR4 SDRAM) and non-volatile (Flash, EEPROM, FRAM) memory for code storage, data buffering, and high-speed cache. ADD covers industrial-temperature and extended-lifecycle memory parts.
Microprocessors
General-purpose CPUs without integrated peripherals — distinct from MCUs. Used in computing-intensive applications with external memory and I/O controllers.
FPGAs and CPLDs
Field-Programmable Gate Arrays and Complex Programmable Logic Devices allow hardware reconfiguration after manufacturing. FPGAs handle parallel processing, high-speed I/O, and custom logic far beyond what a fixed-function IC can achieve — essential in telecom, defense, and data center applications.
