Microchip Technology AT28C040-25BJSL703 is a 4 Megabit (512K x 8) CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM). This parallel interface device offers a fast 250ns access time, enabling efficient data retrieval. It features automatic write capabilities, simplifying write operations. The AT28C040 series operates across a wide temperature range of -55°C to +125°C, with a nominal supply voltage of 5V (4.5V to 5.5V). Packaged in a 32-lead Ceramic Dual In-line Package (CDIP), it is designed for through-hole mounting. This component finds application in industrial control systems, telecommunications infrastructure, and legacy embedded systems requiring reliable non-volatile data storage.
