Hardware Overview
How does it work?
Flash 5 Click is based on the W25N01GVZEIG/IT (1G-bit) Serial SLC NAND Flash Memory from Winbond. The device operates on a single 3.3V power supply with current consumption as low as 25mA active and 10µA for standby. All W25N SpiFlash family devices are offered in space-saving packages, which were previously impossible to use for the typical NAND flash memory. The W25N01GVZEIG/IT 1G-bit memory array is organized into 65,536 programmable pages of 2,048 bytes each. The entire page can be programmed simultaneously using the data from the 2,048-Byte internal buffer. Pages can be erased in groups of 64 (128KB block erase). The W25N01GVZEIG/IT has 1,024 erasable blocks. The Flash 5 Click uses the standard Serial Peripheral Interface (SPI), supporting SPI clock frequencies of up to 104MHz. Besides that, the W25N01GVZEIG/IT provides a new Continuous Read Mode that allows for efficient access to the entire memory array with a single Read command. This feature is ideal
for code-shadowing applications. Also, it offers the highest performance thanks to the Serial NAND Flash with 104MHz Standard/Dual/Quad SPI clocks and a 50MB/S continuous data transfer rate. Given that it has an efficient “Continuous Read Mode,” it allows direct read access to the entire array. However, the performance depends on the main MCU used with this Click board™. A Hold pin, Write Protect pin and programmable write protection provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device ID, one 2,048-Byte Unique ID page, one 2,048-Byte parameter page, and ten 2,048-Byte OTP pages. To provide better NAND flash memory manageability, user-configurable internal ECC and bad block management are also available in W25N01GVZEIG/IT. The W25N01GVZEIG/IT is accessed through an SPI-compatible bus consisting of four signals: Serial Clock (CLK), Chip Select (/CS), Serial Data Input (DI), and Serial Data
Output (DO). Standard SPI instructions use the DI input pin to serially write instructions, addresses, or data to the device on the rising edge of CLK. The DO output pin reads data or status from the device on the falling edge of CLK. For a detailed explanation, please consult the included datasheet. However, MikroElektronika provides a library that contains functions that simplify and speed up working with this device. The provided application example demonstrates the functionality of the library functions. It can be used as a reference for a custom project development. 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.

* # Description
* This application is for storing mass storage.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes driver, resets device, erasing one page of memory, tests communication and configures device.
*
* ## Application Task
* Writes "MikroE" to device memory and then reads it and sends it to log.
