The AT24C08ANPU27 is an 8Kbit I2C serial EEPROM in a DIP8 package. It provides reliable, nonvolatile storage for small data sets used by microcontrollers and embedded systems. This part is compatible with standard I2C bus designs and is suitable for projects that require a compact, easytowire memory device with simple read and write operations. Key benefits Reliable nonvolatile storage: data remains stored without power, making it ideal for configuration data, calibration tables, and small data logs. Simple I2C interface: twowire bus (SCL and SDA) enables straightforward integration with a wide range of microcontrollers and development boards. Flexible device addressing: A0, A1, and A2 address pins allow multiple devices on the same I2C bus, enabling scalable memory expandability. Efficient writes: supports page write operations up to 16 bytes, helping to increase write efficiency and reduce bus traffic. Space and cost efficiency: 8pin DIP package in a compact form factor suitable for breadboard prototyping and compact assemblies.
