Hey all be sure to checkout M25P128 User Module to see the latest module that I have written for SF.

Hello Ryan,
Nice job, I am using the very large Atmel flash at the moment and they are a right royal pain to work with but the customer dictates.

I noticed the clock was 40MHz and the config was HSPLL, have you got the first 160MHz PIC that I have not heard of!!!

Mark in SF you set the clock to the actual frequency you will be running. Using PDS you will encounter the error you mentioned.

In this application I am running a 10MHz clock and x4 to get 40MHz. I have found this configuration to be very stable if others want to duplicate it.

Hi Ryan:
I did test your module,changing only the serial speed to 9600 b,and disabling
the pll. I used a 10 Mhz resonator .
After several test, I only get this result:

I use a 18LF2620 at 3.3 V, with a M25P16 (Numonycs).

Greeting and thanks in advance for your comments.

Ruben, I am not familiar with the M25P16. There could be some page sizing etc that are different. A quick look at the data sheets should show you the difference. I am pretty busy and won't really be able to look at this. If you find anything out please let me know.

Very cool! Have you tried programming the whole 16 MB? What sort of programming times are you seeing to conduct this?

It would be interesting to experiment with some detailed graphics on the chip, even try some video on a colour display.
