1. VDD = 4.5 to 5.5 Vdc, VSS = 0 Vdc, TA = TL to TH, unless otherwise noted.
2. Typical values reflect average measurements at midpoint of voltage range, 25•C only.
3. Values are based on characterization results, not tested in production.
4. Guaranteed by design, not tested in production.
5. If minimum VDD is not reached before the internal POR reset is released, the LVI will hold the part in reset until minimum
VDD is reached.
6. RPU is measured at VDD = 5.0 V.
7. RPD is measured at VDD = 5.0 V, Pulldown resistors only available when KBIx is enabled with KBIxPOL =1.
