How Does The EEPROM 10 Click Board™ Work?
The EEPROM 10 Click Board™ is based on the N24C32, a 32Kb I2C CMOS Serial EEPROM from ON Semiconductor. The EEPROM has excellent energy efficiency and can work in a wide power supply range. Data is written to the EEPROM by providing a starting address, then loading 1 to 32 contiguous bytes into a page write buffer, and then writing all data to non−volatile memory in just one internal write cycle. The same data can be read by providing a starting address and then shifting out data serially while automatically incrementing the internal address count.
The EEPROM 10 Click Board™ communicates with MCU using the standard I2C 2-Wire interface that supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1MHz) modes of operation. The address pins A0, A1, and A2 are programmed by the user and determine the value of the last three LSBs of the slave address, which can be selected by positioning onboard SMD jumpers labelled as ADDR SEL to an appropriate position marked as 0 or 1 (0 set by default). On the other side, the configurable Write Protection function, labelled WP routed to the default position of the PWM pin of the mikroBUS™ socket, allows the user to freeze the entire memory area, thus protecting it from Write instructions.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
MIKROSDK
The EEPROM 10 Click Board™ is supported with mikroSDK - MIKROE Software Development Kit, that needs to be downloaded from the LibStock and installed for the compiler you are using to ensure proper operation of mikroSDK compliant Click board™ demo applications.
