Additional Details

The AT24C02N operates with a supply voltage range of typically 1.8V to 5.5V. It supports the standard I2C bus protocol with clock frequencies up to 400 kHz. The device features a page write mode, allowing for efficient writing of multiple bytes in a single operation. The operating temperature range is generally from -40°C to +85°C. It often comes in a PDIP, SOIC, or TSSOP package. Specific electrical characteristics, such as the write cycle time and endurance, should be verified from the manufacturer's datasheet to ensure suitability for the intended application. These packages facilitate both through-hole and surface-mount assembly, providing flexibility in manufacturing.
