Enhanced Flash Card SD - 512 MB to 4G Storage (6039 4G)

Product Overview

📦 The File 4899 Flash Card SD - XTSD is a unique and innovative storage solution that transforms the conventional capabilities of SD cards into a compact and convenient SMT chip format. With a storage capacity of 512 MB, this device emulates the functionality of a standard SD card while allowing seamless integration with your microcontroller through familiar SD card libraries.

🔧 Technical Features

🌫️ This breakout board features a chip that resembles an SPI Flash storage chip, like the GD25Q16, yet operates as an SD card. Its design allows for straightforward wiring akin to that of an SD card breakout, enabling the use of existing Arduino SD libraries or the CircuitPython sdcard library. The chip is pre-formatted with FAT, ensuring immediate readiness for your projects.

Applications

🔒 You may wonder about the advantages of this specialized chip. Its design is particularly beneficial for applications that require enhanced durability and reliability, such as data logging in environments subject to high vibration. Its fixed, secure structure ensures that the SD card remains properly connected, eliminating concerns about dislodging during operation. This chip is also ideal when space is at a premium or when a microcontroller offers a USB mass storage interface.

Advanced Memory Management

⚡ Unlike standard SPI flash memory, the File 4899 Flash Card chip is equipped with NAND technology, which autonomously manages wear leveling and error correction code (ECC) processes. This means you can effortlessly read and write data without the need to manually erase blocks. With support for clock speeds of up to 50 MHz and a write speed class of 8, this chip delivers impressive performance for various applications.

Ease of Use

👌 Designed for rapid deployment, this breakout simplifies the connection process. It operates in "SPI" mode, complete with integrated level shifters, making it compatible with both 3V and 5V logic levels. Additionally, it features a built-in 3.3V regulator and provides an easy-to-use pull-up resistor on the chip select (CS) line. Simply connect the SPI pins to your microcontroller and utilize your preferred SD library to get started in mere minutes!
