The SD flash subsystem commonly relies on the SDFat16/32 libraries. An 8-pin DIP package of a discrete flash chip is much easier to drop on a protoboard than an SD shield, assuming your development board even supports a shield. While shields provide convenience for prototyping, the final production assembly might not have the budget or the space to include SD hardware. One way to add SD flash to an Arduino system is to use a shield, such as this one by Seeed Studio (three 'e's) I bought at my local Radio Shack for $15. The list below contains a few tradeoffs I think about when I need to decide if I want to use a single 8-pin DIP chip or a full-on SD solution: Many reasons exist to choose a discrete flash chip over an SD subsystem, and vice versa, and you'll need to consider these tradeoffs for your design. Whenever I'm building an Atmel ATMega or Arduino project and I need to record data, I almost always reach for a single SPI WinBond W25Q80BV 1MB flash chip rather than an SD flash subsystem.

This is also a follow-on to my other two data-logging Instructables (an anemometer and a 3-axis wrist accelerometer) that explains how to download the data from the logger flash memory using age-old TTY command line applications found in Linux. This Instructable will show you how to add 1MB of discrete external flash memory to your microcontroller project with what I believe to be the least amount of effort possible. Based on Taichung and new Kaohsiung 12-inch fabs in Taiwan, Winbond keeps pace to develop in-house technologies to provide high-quality memory IC products.Designing with discrete flash is 1/10th the cost, uses a much smaller form factor, and requires significantly less specialized hardware than using SD flash cards. Winbond is headquartered in Central Taiwan Science Park (CTSP), and it has subsidiaries in the USA, Japan, Israel, China, Hong Kong, and Germany.

This also helps the OEM software teams to develop application-code well-suited for new code releases with multiple new feature-set without compromising on Code Storage Flash Memory density limitations. This compatibility is a game-changer for customers designing applications such as 5G modem, 5G edge computing, cloud server, fiber optic modems, and smart IoT segments where they typically increase code-storage flash density 2X every 2 years. For example, the two-die device will support Read While Write operation for OTA updating without suspension of read operations and with no risk of losing the existing firmware image in the event of an unexpected power interruption, providing fast and stable live OTA (Over-The-Air) system firmware update. The new W25Q512NW can also be stacked to 1Gb and 2Gb, which gives designers more flexibility to extend the density up to 2Gb and better performance on Read-While-Write. W25Q512NW can support up to 166 MHz SDR and 80MHz DDR in high read-speed, it can achieve high performance on XIP (eXecute In Place) and Instant-on with QPI. 'Our W25Q512NW SPI NOR Flash delivers on all these requirements, while also providing the best solution in the industry and ensuring the reliable supply capacity that is backwards and forwards compatible to the lowest to the highest flash densities available.' 'Emerging 5G applications require both high-quality and high-density SPI NOR flash,' said Winbond. Winbond Unveils New 1.8V 512Mb SPI NOR flash for 5G and Other High-End Server Applications
