CAT24C256LI-G

CAT24C256LI-G Description

The CAT24C256LI-G from onsemi is a high-performance 256Kbit (32K x 8) serial EEPROM designed for applications requiring reliable non-volatile memory with low-power operation. This I2C-compatible memory IC operates across a wide voltage range (1.8V to 5.5V), making it suitable for both low-power and standard voltage systems. With a 1 MHz clock frequency and 500 ns access time, it delivers efficient data transfer speeds, while its 5ms write cycle time (word/page) ensures rapid updates. The device is housed in an 8-pin DIP through-hole package, ideal for prototyping or legacy designs.
