Microchip Technology AT28HC256-90FC is a 262,144 bit (32K x 8) CMOS Electrically Erasable Programmable Read-Only Memory (EEPROM). This parallel interface device offers a fast 90ns access time and supports asynchronous operation. Key features include automatic write, data polling, and a toggle bit for status indication. The AT28HC256 series is designed for robust operation with a write endurance of 10,000 cycles and a typical page write size of 64 bytes. It operates from a 4.5V to 5.5V supply voltage range, with a standby current of 60µA and a typical active current of 178mA. The component is housed in a 28-lead Ceramic Flat Pack (CDFP28) package, suitable for surface mounting in industrial and commercial applications. Endurance and data retention capabilities make it suitable for applications in industrial control, telecommunications, and data logging.
