Industrial DQ2816A-250

SEEQ DQ2816A-250 is a 2K × 8-bit parallel EEPROM in a 24-pin package, designed for non-volatile data storage in embedded and industrial equipment. It provides 2,048 bytes of storage, making it suitable for small firmware fragments, calibration data, and lookup tables that must persist without power. The 250 in the part number denotes a 250 ns access time, placing it in a mid-range speed class for timing-critical control logic. The device is commonly offered in the DIP-24 form factor, with ceramic DIP variants appearing in some catalogs, which can influence mechanical robustness in rugged environments. The part is cataloged under the DQ2816A-250 designation by SEEQ and appears in supplier listings as DQ2816A250/883 in some inventories. When integrated, the eight data lines connect to the host processor bus while the 11 address lines select one of the 2,048 locations, enabling straightforward storage of small blocks of persistent data alongside application code. This memory component is well-suited for applications where simple, reliable 8-bit data storage is adequate and board space is at a premium.
