Hardware Overview
How does it work?
FRAM 6 Click is based on the CY15B102Q, a 2Mbit ferroelectric random access memory (F-RAM) logically organized as 262,144×8 bits and accessed using an industry-standard serial peripheral interface from Infineon, now part of Infineon. The functional operation of the F-RAM is similar to serial flash and serial EEPROMs, where the significant difference between the CY15B102Q and a serial flash or EEPROM represents the F-RAM's superior write performance, high endurance, and low power consumption. That's why this 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 flash or EEPROM can cause
data loss. The CY15B102Q communicates with MCU through a standard SPI interface that enables very high clock speeds up to 25MHz, supporting the two most common SPI modes, SPI Mode 0 and 3. Unlike serial flash and EEPROM, the CY15B102Q performs write operations at bus speed, where no write delays are incurred. The CY15B102Q supports 10 trillion read/write cycles, or 10 million times more write cycles than EEPROM. Data is written to the memory array immediately after each byte is successfully transferred to the device. The following bus cycle can commence without the need for data polling. An additional feature of this Click board™ represents the configurable Write Protection function labeled as WP routed on the RST 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 write are prohibited when this pin is high, and the address counter is not incremented. Besides, the FRAM 6 Click also has an additional HOLD pin, routed to the PWM pin of the mikroBUS™ socket labeled as HLD, to interrupt a serial operation without aborting it. This 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. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
Features overview
Development board
Nucleo 32 with STM32F031K6 MCU board provides an affordable and flexible platform for experimenting with STM32 microcontrollers in 32-pin packages. Featuring Arduino™ Nano connectivity, it allows easy expansion with specialized shields, while being mbed-enabled for seamless integration with online resources. The
board includes an on-board ST-LINK/V2-1 debugger/programmer, supporting USB reenumeration with three interfaces: Virtual Com port, mass storage, and debug port. It offers a flexible power supply through either USB VBUS or an external source. Additionally, it includes three LEDs (LD1 for USB communication, LD2 for power,
and LD3 as a user LED) and a reset push button. The STM32 Nucleo-32 board is supported by various Integrated Development Environments (IDEs) such as IAR™, Keil®, and GCC-based IDEs like AC6 SW4STM32, making it a versatile tool for developers.

Application Output
1. Application Output - In Debug mode, the 'Application Output' window enables real-time data monitoring, offering direct insight into execution results. Ensure proper data display by configuring the environment correctly using the provided tutorial.
2. UART Terminal - Use the UART Terminal to monitor data transmission via a USB to UART converter, allowing direct communication between the Click board™ and your development system. Configure the baud rate and other serial settings according to your project's requirements to ensure proper functionality. For step-by-step setup instructions, refer to the provided tutorial.
3. Plot Output - The Plot feature offers a powerful way to visualize real-time sensor data, enabling trend analysis, debugging, and comparison of multiple data points. To set it up correctly, follow the provided tutorial, which includes a step-by-step example of using the Plot feature to display Click board™ readings. To use the Plot feature in your code, use the function: plot(*insert_graph_name*, variable_name);. This is a general format, and it is up to the user to replace 'insert_graph_name' with the actual graph name and 'variable_name' with the parameter to be displayed.

* @brief FRAM6 Click example
*
* # Description
* This example demonstrates the use of FRAM 6 click board.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver and performs the click default configuration.
*
* ## Application Task
* Writes a desired number of bytes to the memory and then verifies that it's written correctly
* by reading from the same memory location and displaying the memory content on the USB UART.
