We have manufactured many STM32 boards that have this external flash chip on it (AT25SF081) that we haven't needed to utilize until now. I've spent hours searching but have not found software drivers for it likely due to it being obsolete. It would be really great if I could obtain the drivers for this chip. Can someone provide a link to where it exists?
Hi There,Thank you for posting your question online.Please refer here: AT25SF081 - 8Mbit, 2.3V - 3.6V Range SPI Serial Flash Memory with Dual-I/O and Quad-IO Support | RenesasThis part number is indeed Obsolete.We generally do not provide any Software drivers for our Memories products.On the link I shared above, you can find the Datasheet and based on the Datasheet create your Software Drivers.Best Regards,OV_Renesas
