OPERATING CONDITONS (cont’d)
13.3.2 Operating Conditions with Low Voltage Detector (LVD)
T
Notes:
1. LVD functionality guaranteed only within the V
2. Not tested in production.
3. Not tested in production. The V
When the V
4. Based on design simulation.
5. Use of LVD with capacitive power supply: With this type of power supply, if power cuts occur in the application, it is rec-
ommended to pull V

13.3.3 Internal RC Oscillator and PLL
The ST7 internal clock can be supplied by an internal RC oscillator and PLL (selectable by option byte).
Notes:
1. x4 PLL option only applicable on Flash devices.
