PROGRAM_B Pulse Width

Jump to solution

I am working on a slave serial interface to program an Artix 7 with a Zynq.  Naturally I looked in the data sheet (ds181) for the Artix 7 to find the minimum pulse width for this signal.  To my surprise, PROGRAM_B was not found in the data sheet.  I found the information I needed by looking in the Spartan 6 data sheet (ds162) for PROGRAM_B to find where this parameter is listed, then going back to the Artix 7 data sheet to find the information I needed. 

 

May I request a revision to Table 66 of ds181?  Change the description of Tprogram from "Program pulse width" to PROGRAM_B Pulse Width. 

 

Thanks

bruce_karaffa,

 

I'll put this up there in our doc review for DS181. You are right it should be PROGRAM_B, however, this may take a little while to actually get it into the data sheet. Older device data sheets usually have longer review times.
