    The Flash 6 Click based on W25Q128JV (128M-bit) flash memory from Winbond provides a storage solution for systems with limited space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage.

    The Flash 6 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    The Flash 6 Click based on the W25Q128JV array is organized into 65,536 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128 (32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q128JV has 4,096 erasable sectors and 256 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage.

    The Flash 6 Click uses the standard Serial Peripheral Interface (SPI), supporting SPI clock frequencies of up to 133MHz Single, Dual/Quad SPI clocks. Besides that, the W25Q128JV provides a 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 133MHz Standard/Dual/Quad SPI clocks and a 66MB/S continuous data transfer rate. Given the fact it has a efficient “Continuous Read Mode”, it allows direct read access to the entire array. However, the performance also 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 and SFDP, and a 64-bit Unique Serial Number and three 256-bytes Security Registers.

    The W25Q128JV 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 is used to read data or status from the device on the falling edge of CLK.

    For the detailed explanation, please consult the included datasheet. However, MikroElektronika provides a library which 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™ is designed to be operated only with 3.3V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 5V.
