Note 1: Device is functional at VBORMIN < VDD < VDDMIN, but will have degraded performance. Device functionality
is tested, but not characterized. Analog modules (ADC, op amp/comparator and comparator voltage
reference) may have degraded performance. Refer to Parameter BO10 in Table 30-13 for the minimum and
maximum BOR values.
2: Data in “Typ” column is at 3.3V, +25°C unless otherwise stated.
3: Parameter is characterized but not tested in manufacturing.
4: See Figure 25-6 for configuration information.
5: See Figure 25-7 for configuration information.
6: Resistances can vary by ±10% between op amps.
