AT24C08D-PUM: Microchip’s Reliable 8-Kbit Serial EEPROM for Low-Power Applications
The AT24C08D-PUM is an 8-Kbit serial EEPROM memory device from Microchip Technology, designed for use in systems requiring reliable and non-volatile data storage. Organized as 1024 x 8 bits, this chip offers a practical solution for storing configuration parameters, calibration data, or user settings in a wide range of electronic applications.
Operating over a broad voltage range from 1.7V to 5.5V, the AT24C08D-PUM is ideal for both low-power and mainstream embedded systems. Its I2C-compatible serial interface supports a 400 kHz clock frequency, enabling efficient communication with microcontrollers and other digital components while minimizing pin count and board space. The device supports up to four unique physical addresses using two address pins, allowing up to four devices to share the same I2C bus.
A key feature of this EEPROM is its high reliability and endurance, with a rated endurance of 1 million write cycles and a data retention period of up to 100 years. It also includes hardware write-protection functionality, preventing accidental writes when the WP pin is asserted.
Typical applications include consumer electronics, industrial systems, IoT devices, and automotive subsystems where compact, non-volatile memory with simple interfacing is essential.
The AT24C08D-PUM combines low operating voltage, high endurance, and a compact form factor, making it a versatile choice for modern embedded designs requiring dependable serial EEPROM memory.
