IC/Module: AT24CM02 I2C-Compatible Serial EEPROM

The AT24CM02 module by Atmel provides 262,144 x 8 bits of serial EEPROM. The cascadable feature facilitates up to two devices to share a common 2-wire bus. This I2C-compatible AT24CM02 has byte and page Write speeds equal or less than 10 ms. It is well-suited for use in many industrial and commercial applications.

I2C Interface

The I2C interface operates at 100 kHz in standard mode (1.7V to 5.5V), 400 kHz in fast mode (1.7 to 5.5V) and 1 MHz in fast mode plus (FM+), 2.5V to 5.5V.

SMD Jumpers

EEPROM 3 click features on-board zero-ohm SMD jumper that enables the user to select between a power supply source (3.3V or 5V). Another jumper, ADD, allows for selecting the I2C address.


The I2C interface compatible EEPROM 3 click (1 MHz in fastest mode) is not as fast as the SPI-compatible EEPROM 2 click (5 MHz speed). But it has the benefit of selectable addresses. On soldering the ADD jumpers in opposite positions, the user can use both simultaneously on the same I2C bus line, giving a total of 512 KB of memory.
