DAC7728: Interface with TMS320F28379D

Part Number: DAC7728
Other Parts Discussed in Thread: TMS320F28379D,

Dear Sir,

I wanted to use DAC7728 with the controller. I need to know that the timing requirement of the DAC is compatible with TMS320F28379D or not ?

Do I need more components to meet the timing for write operation into DAC ?

I made the circuit and i joint the address line to DAC and data line as given and regarding CS and Write I tide the lines EM1CS3 memory.

And I followed the datasheet instruction for pins configuration(as given in DAC datasheet).

If the timing will not match then suggest the other parallel DAC which is compatible with TMS320F28379D. I need to decide this as fast as possible.

If there are some FAE that can help me please provide the no.

waiting for reply

Hi,

What do you mean my timing requirements matching with TMS320F28379D ?

This DAC is a parallel interface DAC which is straight forward to interface with any controller and compatible with TMS320F28379D.

I am just asking that when I go through the timing diagram of both datasheets, I found that there are a little bit difference of CS timing i.e. 2nSec.

If you confirm that this DAC is "straight forward to interface with any controller and compatible with TMS320F28379D.", I start to make the PCB design and

order it.

Also that if you provide the interface circuit diagram with the controller, I make double confirm it and help to make the decision early.
