The EEPROM 3 Click Board provides 2 Mbit (2,097,152 bits) of Electrically Erasable Programmable Read Only Memory, organized in bytes. In other words, this click board is an EEPROM memory medium with the capacity of 256 KB. The used EEPROM module has outstanding endurance, with 1,000,000 write cycles and data retention period of over 100 years. The EEPROM module on this click features Schmitt trigger inputs for better noise protection, self-timed write cycles, it has a dedicated write protect pin for hardware protection of stored data, and error detection and correction logic scheme that ensures reliable data output, staying transparent to the host controller.

Product Details


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. .

EEPROM 2 Vs EEPROM 3

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.
