The Microchip Technology AT28C040-20LJ is a 4-Megabit (512K x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) device. It features a fast 200ns asynchronous access time and a parallel interface, making it suitable for applications requiring high-speed data retrieval. This CMOS memory operates within a supply voltage range of 4.5V to 5.5V, with a nominal operating voltage of 5V. The AT28C040 series offers a 10ms maximum write cycle time. Encased in a 44-lead Ceramic Quad Flat Pack (CQFP) package with a metal-sealed cofired construction, this component is designed for robust performance. Its operating temperature range is from -40°C to +85°C. Applications for this device span industrial control systems, telecommunications infrastructure, and embedded computing platforms where reliable non-volatile data storage is crucial.
