13.3.2 Operating Conditions with Low Voltage Detector (LVD)
T
A
= -40 to 125°C, unless otherwise specified
Notes:
1. Not tested in production. The V
DD
rise time rate condition is needed to ensure a correct device power-on and LVD reset.
When the V
DD
slope is outside these values, the LVD may not ensure a proper reset of the MCU.
13.3.3 Auxiliary Voltage Detector (AVD) Thresholds
T
A
= -40 to 125°C, unless otherwise specified
13.3.4 Internal RC Oscillator and PLL
The ST7 internal clock can be supplied by an internal RC oscillator and PLL (selectable by option byte).
