MICROCHIP 24LC256 256Kbit I²C Serial EEPROM DIP8

The MICROCHIP 24LC256-I/P is a high-performance, 256Kbit (32K x 8) CMOS serial E²PROM. Designed to operate across a broad voltage range from 1.7V to 5.5V, it is ideal for advanced, low-power applications including personal communications, data acquisition, and industrial control systems.

This device features a versatile page write capability for up to 64 bytes of data, supporting both random and sequential read operations across its entire 256K address space. Its functional address lines allow for cascading of up to eight devices on the same I²C bus, enabling an addressable memory space of up to 2Mb, making it perfect for expanding system memory.
