AT25XE321DPosted by grai2907 10 points 1 reply
I'm using AT25XE321D serial flash IC in one of the project I'm working on. I've gone through the datasheet of this and was trying to program it using SPI mode. But I found that even at the first step while trying to read the JEDEC ID, it reads the id as 0 (5 Bytes). I proceeded and tried to read status registers and there also I got 0 value. Thinking that it is the default values I tried to do the "write enable" by writing to status register 1 (set bit 1). Even after this when I tried to read the status register 1 value, I get 0 itself.
Is there something I'm missing? Is there any document which can guide me through the correct way of doing this?
