Hello!

I try to connect 17-bit adress wide SDRAM to LPC1778 LQFP144. There only A0-A15 and A24,A25 are available on LQFP144. What are P5[0] EMC_A[24] и P5[1] EMC_A[25]? Can I use it to connect to EMC  in 17-bit wide adress mode?

Regards,
Vasilij.

H, Vaslilij,

There may be some inaccuracy in the DS, we will double check this and get back to you. I confirmed your observation, it seems suspicious.
Thanks,

I have not seen a posted reply from NXP
What was found in the 'double check'?

Mike.

So, I chacked it by myself. Yes there do. P5[0] EMC_A[24]  and P5[1] EMC_A[25] work like emc A[24] emc A[25]. So you can use it.

I too am interested in this subject. I asked a similar question a long time ago (the answer is still pending)
