The A29040BL-55UF from AMIC Technology is a 4Mb parallel NOR Flash memory device organised as 512K × 8 bits, designed for 5.0V-only operation with no additional programming voltage required. Housed in a 32-pin PLCC package, it offers 55 ns access time, an industrial temperature range of -40°C to +85°C, and a standard 8-bit parallel interface, making it suitable for embedded code storage, firmware memory and legacy 5V system designs that need fast random read access and in-system reprogrammability.
