Supports Active Serial (AS) x1 and AS x4 configuration modes for Intel Cyclone and Arria FPGAs. 2.7-3.6V operation at up to 100MHz clock. ISP via JTAG through the FPGA. >100K erase cycles with >20 year retention. A suffix denotes 64KB sectors, S suffix denotes standard security, I suffix denotes -40 to 85\u00b0C industrial temperature, 8 suffix denotes pin config option 8 (RESET# and HOLD#), N suffix denotes SOIC-8 package. Ideal for Intel FPGA configuration storage.","working_principle":"The EPCQ16A stores the FPGA configuration bitstream in non-volatile Flash memory. During power-up, the Intel FPGA initiates configuration by driving the AS interface \u2014 the FPGA acts as the master, providing clock (DCLK) and reading data from the EPCQ. In AS x1 mode, 1 bit per clock is read; in AS x4 mode, 4 bits per clock are read for 4x faster configuration. The EPCQ also supports ISP: the FPGA can reprogram the EPCQ through the JTAG interface using Intel's Quartus Programmer software. The write-protection feature uses status register bits (BP[3:0] and TB) to define protected sectors, preventing accidental corruption of critical configuration data. The 4KB subsector erase allows efficient partial updates without erasing the entire device.","pin_description":"
