XC9500: Minimum RESET signal pulse width


Record #1707

Product Family:  Hardware

Product Line:  9500

Problem Title:
XC9500: Minimum RESET signal pulse width


Problem Description:
What is the minimum RESET pulse width for 9500 parts?


Solution 1:

Currently we do not spec the XC9500  RESET pulse width.

To gain an approximation of this value, use the tPD spec.
This spec for 'I/O to Output Valid', is listed in the XC9500
data sheets for all of the various speed grades, and also
shown below:

SPEED GRADE	   tPD (or approximation for RESET pulse width)
--------------------------------------------------------------
   -5		  5.0ns
   -7		  7.5ns
   -10		  10.0ns
   -15		  15.0ns
   -20		  20.0ns
