Click board with full memory write protect supports up to two devices on single two-wire bus
MikroElektronica's EEPROM 3 click carries Atmel’s AT24CM02 DIP-8 socket EEPROM chip with 256KB of memory and is available now from Digi-Key. The chip has byte and page write speeds equal to or less than 10ms. The EEPROM3 has 100 years of data retention and is rated for a million write cycles. The memory is organized as 262,144 x 8 bits. The board communicates with the target board MCU through the mikroBUS I2C interface (SCL, SDA pins) with speeds up to 1MHz. An onboard jumper allows the selection of the device address (two of them can be connected on the same I2C bus for a total of 512KB). This click board is designed to be powered at 3.3V or a 5V.
The Microchip AT24CM02 device 2Mb two-wire serial EEPROM with full memory write protect supports up to two devices on a single two-wire bus. The EEPROM has 262,144 words x 8 bits, and is optimized for industrial and commercial applications where low-power and low-voltage operations are essential.
