Hardware Overview

How does it work?

EEPROM 13 Click is based on the M24M01E, an electrically erasable programmable memory with enhanced hardware write protection for entire memory from STMicroelectronics. The M24M01E has software and hardware write protection features and random and sequential read modes. If the address area is write-protected, the write instruction is not executed. During the internal write cycle, the serial data is turned off internally, and the

device does not respond to any requests. The performance features cover enhanced ESD/latch-up protection, more than 4 million write cycles, more than 200 years of data retention, and a very fast wake-up time (less than 5μs). EEPROM 13 Click uses a standard 2-wire I2C interface to communicate with the host MCU, supporting standard, fast, and fast mode plus with up to 1MHz of frequency clock. The write control WC pin serves

as a write protect option and is active with a High logic state. 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. Also, this 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.

Features overview

Development board

Clicker 2 for Kinetis is a compact starter development board that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It comes with an onboard 32-bit ARM Cortex-M4F microcontroller, the MK64FN1M0VDC12 from NXP Semiconductors, two mikroBUS™ sockets for Click board™ connectivity, a USB connector, LED indicators, buttons, a JTAG programmer connector, and two 26-pin headers for interfacing with external electronics. Its compact design with clear and easily recognizable silkscreen markings allows you to build gadgets with unique functionalities and

features quickly. Each part of the Clicker 2 for Kinetis development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the Clicker 2 for Kinetis programming method, using a USB HID mikroBootloader or an external mikroProg connector for Kinetis programmer, the Clicker 2 board also includes a clean and regulated power supply module for the development kit. It provides two ways of board-powering; through the USB Micro-B cable, where onboard voltage regulators provide the appropriate voltage levels to each component on the board, or

using a Li-Polymer battery via an onboard battery connector. All communication methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, reset button, and several user-configurable buttons and LED indicators. Clicker 2 for Kinetis is an integral part of the Mikroe ecosystem, allowing you to create a new application in minutes. Natively supported by Mikroe software tools, it covers many aspects of prototyping thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output via Debug Mode

1. Once the code example is loaded, pressing the "DEBUG" button initiates the build process, programs it on the created setup, and enters Debug mode.

2. After the programming is completed, a header with buttons for various actions within the IDE becomes visible. Clicking the green "PLAY" button starts reading the results achieved with the Click board™. The achieved results are displayed in the Application Output tab.

Library Description

This library contains API for EEPROM 13 Click driver.

Key functions:

  • eeprom13_memory_write - This function writes a desired number of data bytes starting from the selected memory address

  • eeprom13_memory_read - This function reads a desired number of data bytes starting from the selected memory address

  • eeprom13_hw_write_enable - This function disabled hardware write protection of the entire memory

 * @brief EEPROM 13 Click example
 *
 * # Description
 * This example demonstrates the use of EEPROM 13 click board?.
 * The demo app writes specified data to the memory and reads it back.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C module, log UART, and additional pins.
 *
 * ## Application Task
 * The demo application writes a desired number of bytes to the memory 
 * and then verifies if it is written correctly
 * by reading from the same memory location and displaying the memory content.
 * Results are being sent to the UART Terminal, where you can track their changes.
