La carte Flash 10 Click Board™ est une carte complémentaire compacte qui représente une solution de mémoire extrêmement fiable. Cette carte comprend l'AT25FF321A, une solution de mémoire Flash série 32 Mbit (2Mx16) configurable SPI de Dialog Semiconductor. L'AT25FF321A est une solution idéale pour les systèmes dans lesquels le code du programme est copié de la mémoire Flash vers la RAM intégrée ou externe (code shadow) pour l'exécution et où de petites quantités de données sont stockées et mises à jour localement dans la mémoire Flash. Elle dispose d'une architecture d'effacement flexible et optimisée pour les applications de stockage de code et de données, d'une protection non volatile et de quatre registres de sécurité OTP spécialisés de 128 octets pour stocker un identifiant d'appareil unique et un stockage de clé verrouillée. Cette mémoire peut supporter de nombreux cycles d'écriture (minimum 100 000) et a une période de conservation des données supérieure à 20 ans. Cette carte Click board™ convient au stockage et au transfert de données dans les appareils grand public, les systèmes d'entreprise et les applications industrielles.
La carte Flash 10 Click Board™ 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 Flash 10 Click Board™ Work?
The Flash 10 Click Board™ as its foundation uses the AT25FF321A, a highly reliable serial Flash memory solution designed for use in a wide variety of high-volume consumer and connected applications from Dialog Semiconductor. The AT25FF321A is organized as a 32Mbit (16x2 Mbit physical block) Flash memory ideally suited for systems in which program code is shadowed from Flash memory into embedded or external RAM (code shadow) for execution and where small amounts of data are stored and updated locally in the Flash memory. The AT25FF321A specifies a minimum of 100.000 endurance cycles with data retention of a minimum of 20 years, giving it the capability to handle unlimited reads/writes to the memory.
The AT25FF321A's erase block sizes are optimized to meet the needs of today's code and data storage applications, supporting flexible and optimized erase architecture for code and data storage applications (4kB, 32kB, and 64kB block erase operations) and a full-chip erase feature. The most efficient use of memory space can be achieved by optimizing the erase blocks' size. Also, the AT25FF321A contains four specialized 128-byte One-Time Programmable (OTP) security registers which can be used to store a unique device ID and locked key storage.
The Flash 10 Click Board™ communicates with MCU through a standard SPI interface supporting the two most common SPI modes, SPI Mode 0 and 3. Furthermore, this Click board™ provides additional hardware-controlled functions. The configurable Write Protection, marked as WP and routed on the PWM pin of the mikroBUS™ socket, protects all registers (including status and configuration) from write operations and must be held low to inhibit all the write operations to registers. When this pin is low, all memory and register writes are prohibited, and the address counter is not incremented.
Also, it is possible to use the Reset or Hold function through the RST pin of the mikroBUS™ socket, depending on the state of the HOLD/RESET bit 7 in Status Register 3. In the case of the Hold function, this pin temporarily pauses serial communication without deselecting or resetting the device, while in the case of the Reset feature, a low logic level on the RST pin puts the AT25FF321A into a Reset state.
The Flash 10 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.
