Hello,
As some of you may know, a company called Adesto Technologies bought Atmel's DataFlash series of SPI flash devices.
I bought a few chips back when they were branded with Atmel's logo, and they worked like a charm. Recently, I decided to pick up Adesto's equivalent of my favorite DataFlash module, the AT45DB161E. Mind you, these were the exact same chips that I had bought from Atmel.
After getting them back, I wired them up exactly the same way I had done the Atmel chips, used exactly the same library, and they don't work. I've tried wiring up three of them to ensure that it wasn't a soldering error or accidentally overheating the chip whilst soldering issue.
Any ideas? The Adesto datasheet is identical to Atmel's with the exception of their logos and color schemes.
Thank you,
George
