I am trying to interface Flash AT29C512 with AT89C51 How do read and write serially between the 8 bit 8051 and 24 bit Flash,
Kindly help if some one has worked on this.
"I am trying to interface Flash AT29C512..."
"The flash SST25VF512 device..."
So which one is it? Make your mind up!
"is it ok?"
What does the Datasheet say?
If you do what the Datasheet says, it will be OK; otherwise not.
both should be the same Atmel 512 device, SST25VF512 could mean it Serial flash with Super Flash technology, the data sheet also says so pinout has serial I/O
actually, we are interfacing SST25VF512 with 8051 atmel but the program is being loaded in AT29C512
sorry for that, so sst is serial flash with low power consumption
thanks,
actually, we are interfacing SST25VF512 with 8051 atmel but the program is being loaded in AT29C512 which is accessed via external access of 8051
