Das Flash 10 Click Board™ ist eine kompakte Zusatzplatine, die eine äußerst zuverlässige Speicherlösung darstellt. Diese Platine verfügt über das AT25FF321A, eine SPI-konfigurierbare serielle 32-Mbit-Flash-Speicherlösung (2Mx16) von Dialog Semiconductor. Das AT25FF321A ist eine ideale Lösung für Systeme, in denen Programmcode zur Ausführung vom Flash-Speicher in eingebetteten oder externen RAM (Code Shadow) gespiegelt wird und in denen kleine Datenmengen lokal im Flash-Speicher gespeichert und aktualisiert werden. Es verfügt über eine flexible und optimierte Löscharchitektur für Code- und Datenspeicheranwendungen, nichtflüchtigen Schutz und vier spezielle 128-Byte-OTP-Sicherheitsregister zum Speichern einer eindeutigen Geräte-ID und eines gesperrten Schlüsselspeichers. Dieser Speicher hält vielen Schreibzyklen stand (mindestens 100 KB) und hat eine Datenaufbewahrungsdauer von mehr als 20 Jahren. Dieses Click Board™ ist für die Speicherung und Datenübertragung in Verbrauchergeräten, Unternehmenssystemen und industriellen Anwendungen geeignet.
Das Flash 10 Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.
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.
