Can someone please guide me reading the part number? The screenshots are from a datasheet of a watchdog (STWD100).

  • \$\begingroup\$ Hi @Radiohead I saw that, it helps me to understand the ordering code, but what I cannot relate are the Wathdog timeouts.. For example STWD100xY. Does this mean STWD?Y? (? being wild card) \$\endgroup\$ – Rakesh Mehta Apr 11 '18 at 15:48
  • \$\begingroup\$ That one in particular would be STWD100YxYxx3F, being the first "x" the output type and the "xx" the package \$\endgroup\$ – Radiohead Apr 11 '18 at 15:55
  • \$\begingroup\$ If that is the case then what does STWD100YxW mean? \$\endgroup\$ – Rakesh Mehta Apr 11 '18 at 15:59
  • \$\begingroup\$ The Y appears to be added as a new version. The Device Version will be the 2nd or 3rd (automotive grade) character. Timing's are shown. For W \$t_{WD} = 6.3ms\$. \$\endgroup\$ – StainlessSteelRat Apr 11 '18 at 16:11
