Microchip Technology AT28C040-25FM is a 4Mbit (512K x 8) parallel CMOS EEPROM offering an access time of 250ns. This device features automatic write capabilities and supports data polling for efficient read/write operations. It operates from a single 5V supply (4.5V to 5.5V) and includes a toggle bit for write completion detection. The AT28C040 series is suitable for applications requiring non-volatile data storage in industrial, automotive, and telecommunications sectors. This component utilizes a 32-lead Ceramic Flatpack (CDFP32, R-CDFP-F32) with a terminal pitch of 1.27mm, designed for surface mounting. Its operating temperature range is -55°C to +125°C.
