137 / 201 page ![]() DocID022152 Rev 6 137/201 STM32F405xx, STM32F407xx Electrical characteristics Figure 52. Power supply and reference decoupling (VREF+ connected to VDDA) 1. VREF+ and VREF– inputs are both available on UFBGA176. VREF+ is also available on LQFP100, LQFP144, and LQFP176. When VREF+ and VREF– are not available, they are internally connected to VDDA and VSSA. 5.3.22 Temperature sensor characteristics Table 69. Temperature sensor characteristics Symbol Parameter Min Typ Max Unit TL(1) VSENSE linearity with temperature - ±1 ±2°C Avg_Slope(1) Average slope - 2.5 mV/°C V25(1) Voltage at 25 °C - 0.76 V tSTART(2) Startup time - 6 10 µs TS_temp(2) ADC sampling time when reading the temperature (1 °C accuracy) 10 - - µs 1. Guaranteed by characterization. 2. Guaranteed by design. Table 70. Temperature sensor calibration values Symbol Parameter Memory address TS_CAL1 TS ADC raw data acquired at temperature of 30 °C, VDDA=3.3 V 0x1FFF 7A2C - 0x1FFF 7A2D TS_CAL2 TS ADC raw data acquired at temperature of 110 °C, VDDA=3.3 V 0x1FFF 7A2E - 0x1FFF 7A2F |
