Cloud Power Management Solutions

Cloud and data center power infrastructure is entering an unprecedented period of growth, driven by hyperscale expansion, AI workloads, and the rapid rise of data‑intensive applications. As cloud service providers and enterprise data centers scale global footprints, efficient, reliable power delivery has become a critical enabler of performance, availability, and total cost of ownership.

N24C256X 256Kb I2C CMOS Serial EEPROM

onsemi N24C256X 256Kb I2C CMOS Serial EEPROM offers low-power CMOS technology and is internally organized as 32,768 words of 8-bit each. This EEPROM supports the standard (100kHz), fast (400kHz), and fast-plus (1MHz) I2C protocol. The N24C256X CMOS Serial EEPROM features a 64-byte page write buffer, a 128-bit factory-set read-only unique ID, and user programmable permanent write protection. This EEPROM operates at a 1.7V to 5.5V supply voltage range and 1.2V-referenced SCL and SDA. The N24C256X CMOS Serial EEPROM includes 1,000,000 program/erase cycles and 100-year data retention in an ultra-thin 4-ball WLCSP package. This CMOS Serial EEPROM is Pb−free, Halogen-free/BFR-free, and RoHS compliant. The N24C256X CMOS Serial EEPROM is ideal for mobile phone cameras and wireless devices.
