Details, datasheet, quote on part number: MIKROE-1989

MikroElektronica's EEPROM 3 click carries Atmel’s AT24CM02 DIP-8 socket EEPROM chip with 256 KB of memory. The chip has byte and page write speeds equal to or less than 10 ms. 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 1 MHz. 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 512 KB). This click board is designed to be powered at 3.3 V or a 5 V.

Features, Applications

Before using your click boardTM, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package.

The AT24CM02 device has byte and page write speeds equal or less than 10 ms. The chip is specified for million write cycles, with more than 100 years of data retention. The I2C interface operates 100kHz in standard mode, 400kHz in Fast mode and 1 MHz in Fast mode plus (FM+). The selectable I2C address allows you to connect two EEPROM 3 clicks to the same I2C bus, for a total 512KB of memory. The memory is organized x 8 bits. EEPROM 3 click is suitable for storing initialization and configuration data in your designs.

EEPROM 3 click carries Atmel's AT24CM02 DIP-8 socket EEPROM chip with KB of memory. The board communicates with the target MCU through the mikroBUSTM I2C interface (SCL, SDA pins) with speeds to 1 MHz. The chip allows for an entire page of data (256 bytes) to be written in a single Write cycle. The board is designed to use either a 5V power supply. A onboard LED will indicate the presence of a power supply.

Turn the board upside down so that the bottom side is facing you upwards. Place shorter pins of the header into the appropriate soldering pads.

Turn the board upward again. Make sure to align the headers so that they are perpendicular to the board, then solder the pins carefully.

Once you have soldered the headers your board is ready to be placed into the desired mikroBUSTM socket. Make sure to align the cut in the lower-right part of the board with the markings on the silkscreen at the mikroBUSTM socket. If all the pins are aligned correctly, push the board all the way into the socket.

Once you have done all the necessary preparations, it's time to get your click boardTM up and running. We have provided examples for mikroCTM, mikroBasicTM and mikroPascalTM compilers on our Libstock website. Just download them and you are ready to start.
