Dear Sir/Madam,
I'm using At89C51Ed2 controller based controller board. In that board has the following interfaces
1. External Flash of 64Kb 2. External SRAM of 64Kb 3. Digital I/O 4. ADC 6. Display (LCD display)
Platform: Windows Xp3. Tools: Keil and Flash Programmer Flip.
My question is, Is there any potability to flash external Flash memory by using Flip software?
Can i execute code from external flash? is there any setting as per data sheet EA have to configure.
Regards , Thiru N
the problem you have is that !CE is only checked at reset.
to switch between internal and external memory, you will need an external flip-flop.

PS your customer is crazy, EDUCATE HIM. (s)he evidently does not have any idea that todays '51 derivatives have plenty internal code storage
Thank you,
>>to switch between internal and external memory, you will need an external flip-flop
