BOD and POR Characteristics

Table 1. Power Supply Characteristics
Symbol Description Condition Min. Typ. Max. Unit
SRON Power-on Slope   - - 100(1,2) V/ms
Notes:
  1. 1.For design guidance only and not tested in production.
  2. 2.A slope faster than the maximum rating can trigger a Reset of the device if changing the voltage level after an initial power-up.
Table 2. Power-on Reset (POR) Characteristics
Symbol Description Condition Min. Typ. Max. Unit
VPOR POR threshold voltage on VDD falling VDD falls/rises at 0.5 V/ms or slower 0.8(1) - 1.6(1) V
POR threshold voltage on VDD rising 1.4(1) - 1.8
Note:
  1. 1.For design guidance only. Not tested in production.
