hi gyz
i am working on some data transfer project with AT89C51 or 52 and 24C512 Memory
all i want to do is copy 1st memory data to 2nd memory
i made the sch on isis and and i like assembly lang for programing
now the problum is that if i select the processor freq less then 800kHz it copy data but when i increase speed that is 12MHz the write function dont work
i think there is some write cycle timing missing or some thing
i can upload or mail the isis or code etc
if any 1 help me in this
i will b very happy
 

after every write command you have to give 5ms delay before writing next page or byte are u doing that..
Regards
 

thanks 4 d reply
i tried different delay and the sample code from atmel but some thing is still missing
ithink i am stuck somewhere.
this is my code and sch.
if you please provide me an example code in assembly than i think this will help me.
thanks
