190 / 226 page  Electrical characteristics ST7FOXF1, ST7FOXK1, ST7FOXK2 190/226 12.3 Operating conditions 12.3.1 General operating conditions TA = -40 to +85 °C unless otherwise specified. 12.3.2 Operating conditions with Low Voltage Detector (LVD) TA = -40 to 85 °C unless otherwise specified. , Table 69. General operating conditions Symbol Parameter Conditions Min Max Unit VDD Supply voltage fCPU = 8 MHz max. 4.5 5.5 V fCPU CPU clock frequency 4.5 V ≤ V DD≤5.5 V up to 8 MHz Table 70. Operating characteristics with LVD Symbol Parameter Conditions Min Typ Max Unit VIT+(LVD) Reset release threshold (VDD rise) 3.9 4.2 4.5 V VIT-(LVD) Reset generation threshold (VDD fall) 3.7 4.0 4.3 Vhys LVD voltage threshold hysteresis VIT+(LVD)-VIT-(LVD) 150 mV VtPOR VDD rise time rate (1)(2) 1. Not tested in production. The VDD rise time rate condition is needed to ensure a correct device power-on and LVD reset release. When the VDD slope is outside these values, the LVD may not release properly the reset of the MCU. 2. Use of LVD with capacitive power supply: with this type of power supply, if power cuts occur in the application, it is recommended to pull VDD down to 0 V to ensure optimum restart conditions. Refer to circuit example in Figure 89 on page 207. 2 µs/V IDD(LVD) LVD current consumption VDD = 5 V 80 140 µA |
