La carte Excelon-Ultra Click Board™ est une carte complémentaire compacte dotée de la mémoire non volatile la plus fiable. Cette carte est équipée de la CY15B116QSN, une mémoire non volatile de 16 Mbits hautes performances qui utilise un processus ferroélectrique avancé d'Infineon Technologies. Une mémoire vive ferroélectrique (FRAM) est non volatile, effectue des lectures et des écritures via des commandes SPI et assure 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 la mémoire Flash série et d'autres mémoires non volatiles. Cette carte Click board™ convient à toutes les applications qui nécessitent un accès rapide et une grande fiabilité des données stockées, ainsi qu'une endurance illimitée.
La carte Click Board™ Excelon-Ultra 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 Excelon-Ultra Click Board™ Work?
The Excelon-Ultra Click Board™ as its foundation uses the CY15B116QSN, a high-performance 16-Mbit nonvolatile memory that employs an advanced ferroelectric process from Infineon. The memory array is logically organized as 2,097,152 × 8 bits and is accessed using an industry-standard serial peripheral interface (SPI) bus. The CY15B116QSN combines a 16-Mbit F-RAM with the high-speed Quad SPI SDR and DDR interfaces, enhancing FRAM technology's nonvolatile write capability.
The key differences between the CY15B116QSN and a serial flash are the FRAM's superior write performance, high endurance, and lower power consumption. The CY15B116QSN is ideal for nonvolatile memory applications, requiring frequent or rapid writes. Examples range from data collection, where the number of write cycles may be critical, to demanding industrial controls where the long write time of serial Flash can cause data loss.
The Excelon-Ultra Click Board™ communicates with MCU using an industry-standard SPI interface supporting the two most common modes, SPI Mode 0 and 3, with a maximum frequency of 108MHz. 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. It supports 1e14 read/write cycles or 100 million times more write cycles than EEPROM. In addition, the CY15B116QSN offers substantial write endurance compared to other nonvolatile memories.
Furthermore, this Click board™ provides additional hardware-controlled functions. The configurable Write Protection function, routed on the PWM pin of the mikroBUS™ socket, protects all registers (including status and configuration) from write operations when the SRWD bit (SR1[7]) is set to '1'. The WP pin must be held high to inhibit all the write operations to registers. When this pin is high, all memory and register writes are prohibited, and the address counter is not incremented. Also, it has a Reset feature routed to the RST pin on the mikroBUS™ socket, which puts the CY15B116QSN into a Reset state with a low logic level, and with a high level operates module normally.
The Excelon-Ultra Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with 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.

Software Support
We provide a library for the Excelon-Ultra Click Board™ and a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on the MikroE Github account.
Library Description
This library contains an API for the Excelon-Ultra Click Board™ driver.
Key Functions
excelonultra_cfg_setup- Config Object Initialization function.excelonultra_init- Initialization function.excelonultra_default_cfg- Click the Default Configuration function.
Example Description
This example is a showcase of the device and its library ability. In this example is shown device ID, ability to manipulate with memory. After default configuration, device IDs are logged. After that, the application Writes data to memory, reads data from memory, clears data from memory and checks if data is cleared by reading that same memory address.
void application_task ( void )
{
static uint32_t memory_address = 0x00000055;
static uint8_t data_selection = 1;
static uint8_t write_len;
char to_write[ 50 ] = { 0 };
char read_from[ 50 ] = { 0 };
if (data_selection)
{
strcpy( to_write, MIKROE_DATA );
data_selection = !data_selection;
}
else
{
strcpy( to_write, CLICK_DATA );
data_selection = !data_selection;
}
write_len = strlen( to_write );
log_printf( &logger, " > Writing data to memory: %srn", to_write );
excelonultra_write_data_to_memory( &excelonultra, memory_address, to_write, write_len );
Delay_ms( 500 );
excelonultra_read_data_from_memory( &excelonultra, memory_address, read_from, write_len );
log_printf( &logger, " > Read data from memory: %srn", read_from );
