Hello.
I have simillar problem. Write and read to/from buffers work fine but when I transfer data into main memory I only have correct first byte and all others are FF. This problem is always on all pages.
Thanks for help.

Did You solve this problem?

Hi
I just found this url which might be of interest.
http://www.compsys1.com/workbench/AT45DB/at45db.html
It provides some test code to read/write to the AT45 part, though I haven't tried it. Nor do I know anything about this website, I just "found" it.
Regards
Chris

hi there
Can you please tell me what circuit you used to sort out the voltage level between the 5v of the pic and the 3v of the at45
|
If I am reading the DATASHEET correctly, the device runs at the low voltage but...
from the DATASHEET
All Input Voltages
(including NC Pins)
with Respect to Ground ...................................-0.6V to +6.25V

Always wear safety glasses while programming.

You could use voltage divider made with resistor or much fancy level converter circuits, ICs, or run the whole thing @3v

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
