delay of nano second

15 or 20 cm of coax cable or PCB trace has about 1ns of delay.

delay of nano second

Maybe you could use a delay line component. They usually come in an ordinary DIP or SMD package. Search Google for various manufacturers. Here's one:

What do you mean by "code"? Computer program code or HDL code?

We can't give you program code when you do not tell us what you are using. Tell us everything, then tell more. Maybe we can help.

Re: delay of nano second

Tell us the clock frequency of your controller. Expecting "code" for 1ns delay, your controller must be running on 10GHz.

Re: delay of nano second

I think, you do not need this delay at all.
May be you want 1us delay?

I think, it's basically a misunderstanding. MF RC500 has a common peripheral interface. Shouldn't need a particular delay here. In some cases, processor bus parameters may need adjusting, but a delay is rather unlikely. What's your processor and why do you think needing a delay?
