Microchip Technology's AT28HC256-70UC is a 256 Kbit (32K x 8) CMOS Parallel EEPROM. This device offers a fast 70ns access time and features automatic write capabilities, simplifying data storage operations. Designed for robust performance, it operates from a single 5V supply (4.5V to 5.5V) and maintains functionality across a 0°C to 70°C temperature range. The AT28HC256-70UC utilizes a 28-pin Ceramic Pin Grid Array (CPGA) package with a 2.54mm terminal pitch, suitable for demanding applications in industrial control, telecommunications, and data logging systems. Its parallel interface and asynchronous operating mode ensure efficient data transfer for embedded systems requiring non-volatile memory.
