Microchip Technology's AT28C256F-20DM is a 262,144-bit (32K x 8) CMOS Parallel EEPROM featuring a 200ns access time. This device supports parallel data transfers and offers a robust 10,000 endurance rating. It incorporates Automatic Write and Data Polling features for efficient data management, along with a Toggle Bit for status monitoring. The AT28C256 series is designed for operation across a wide temperature range, from -55°C to +125°C, with supply voltage compatibility from 4.5V to 5.5V. The component is housed in a 28-lead ceramic dual in-line package (CDIP28) with through-hole mounting. Applications for this non-volatile memory include industrial control, aerospace, and defense systems requiring reliable data storage in demanding environments. The write cycle time is a maximum of 3ms.
