Additional Details

The AT24C02-10SC typically operates at a voltage range of 1.8V to 5.5V. The 'SC' suffix indicates that it comes in an 8-lead SOIC (Small Outline Integrated Circuit) package. It supports both 100 kHz and 400 kHz I2C clock frequencies, depending on the operating voltage. The device includes a self-timed write cycle, simplifying write operations for the host microcontroller. This device is now end-of-life.
