Microchip Technology's 28C256 is a 32K x 8 bit CMOS EEPROM, offering 262,144 bits of non-volatile memory. This parallel interface device features a maximum access time of 150ns and supports asynchronous operation. The 28C256-15I-K is housed in a 32-pin CQCC ceramic package, designed for reliable performance across an industrial temperature range of -40°C to +85°C. It operates from a 4.5V to 5.5V supply, with a typical standby current of 150µA and a maximum active current of 70mA. Key features include data polling for write completion confirmation and a toggle bit for status monitoring. The device supports automatic write operations and offers an endurance of 10,000 write cycles. Applications span industrial control, automotive systems, and consumer electronics requiring robust data storage.
