142 / 193 page  Electrical characteristics STM32F412xE/G 142/193 DocID028087 Rev 4 Figure 49. Power supply and reference decoupling (VREF+ connected to VDDA) 1. VREF+ and VREF- inputs are both available on UFBGA100. VREF+ is also available on LQFP100. When VREF+ and VREF- are not available, they are internally connected to VDDA and VSSA. 6.3.21 Temperature sensor characteristics Table 77. 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, not tested in production. 2. Guaranteed by design, not tested in production. Table 78. 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 |
