The Microchip Technology AT28HC256-90FM is a 262,144-bit (32K x 8) CMOS EEPROM offering 90ns asynchronous parallel access. This non-volatile memory device supports automatic write operations and features data polling and toggle bit functionality for efficient data management. With a high endurance of 10,000 write cycles, it is suitable for applications requiring frequent data updates. The AT28HC256-90FM operates from a 4.5V to 5.5V supply and is available in a 28-lead ceramic dual flat pack (CDFP28) package, designed for surface mounting. Its robust construction and MIL-STD-883 screening make it ideal for demanding environments within industrial, aerospace, and defense sectors. The device specifications include a maximum standby current of 0.06mA and a maximum supply current of 178mA during active operation.
