La FRAM 5 Click Board™ est une carte complémentaire compacte représentant une solution de mémoire vive ferroélectrique hautement fiable. Cette carte est équipée du FM24V10, une mémoire non volatile de 1 Mbit utilisant un processus ferroélectrique avancé organisé en 128 000 mots de 8 bits chacun d'Infineon. Cette FRAM configurable I2C effectue des opérations de lecture et d'écriture similaires à une RAM, offrant une conservation fiable des données pendant 151 ans tout en éliminant les complexités, les frais généraux et les problèmes de fiabilité au niveau du système causés par l'EEPROM et d'autres mémoires non volatiles.

La carte Click Board™ FRAM 5 est supportée par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The FRAM 5 Click Board™ Work?
The FRAM 5 Click Board™ as its foundation uses the FM24V10, a 1Mbit ferroelectric random access memory (FRAM) logically organized as 131,072×8 bits and accessed using an industry-standard I2C interface from Infineon. The functional operation of the FRAM is similar to serial I2C EEPROM, where the significant difference between the FM24V10 and EEPROM represents the F-RAM's superior write performance, high endurance, and low power consumption. The FRAM 5 Click Board™ is ideal for nonvolatile memory applications requiring frequent or rapid writes, where example ranges from data collection to demanding industrial controls where the long write time of serial EEPROM can cause data loss.
The FRAM 5 Click Board™ communicates with MCU using the standard I2C 2-Wire interface, supporting operation with a clock frequency up to 3.4MHz. Unlike serial EEPROM, the FM24V10 performs write operations at bus speed, where no write delays are incurred. It provides reliable data retention for 151 years while eliminating the complexities, overhead, and system-level reliability problems caused by EEPROM and other nonvolatile memories and supports 10 trillion (1014) read/write cycles or 100 million times more write cycles than EEPROM. Besides, the FM24V10 allows choosing its I2C slave address using the SMD jumpers labelled ADDR SEL. The selection can be made by positioning the SMD jumpers to an appropriate position marked as 1 or 0.
An additional feature of this FRAM represents the configurable Write Protection function labelled as WP routed on the PWM pin of the mikroBUS™ socket. The WP pin protects the entire memory and all registers from write operations and must be set to a high logic state to inhibit all the write operations. All memory and register writes are prohibited when this pin is high, and the address counter is not incremented.
The FRAM 5 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Key functions
-
fram5_check_communicationThis function checks the communication by reading and verifying the device ID. -
fram5_memory_writeThis function writes a desired number of data bytes starting from the selected memory address. -
fram5_memory_readThis function reads a desired number of data bytes starting from the selected memory address.
Example Description
This example demonstrates the use of the FRAM 5 Click Board™ by writing specified data to the memory and reading it back.

Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, 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 MikroElektronika compilers.
MIKROSDK
The FRAM 5 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
