104 / 149 page  Electrical characteristics STM32L432KB STM3L432KC 104/149 DocID028798 Rev 2 In the user application, the number of I/O pins which can drive current must be limited to respect the absolute maximum rating specified in Section 6.2: • The sum of the currents sourced by all the I/Os on VDDIOx, plus the maximum consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating ΣIVDD (see Table 17: Voltage characteristics). • The sum of the currents sunk by all the I/Os on VSS, plus the maximum consumption of the MCU sunk on VSS, cannot exceed the absolute maximum rating ΣIVSS (see Table 17: Voltage characteristics). Output voltage levels Unless otherwise specified, the parameters given in the table below are derived from tests performed under the ambient temperature and supply voltage conditions summarized in Table 20: General operating conditions. All I/Os are CMOS- and TTL-compliant (FT OR TT unless otherwise specified). Input/output AC characteristics The definition and values of input/output AC characteristics are given in Figure 18 and Table 58, respectively. Table 57. Output voltage characteristics(1) Symbol Parameter Conditions Min Max Unit VOL Output low level voltage for an I/O pin CMOS port(2) |IIO| = 8 mA VDDIOx ≥ 2.7 V -0.4 V VOH Output high level voltage for an I/O pin VDDIOx-0.4 - VOL(3) Output low level voltage for an I/O pin TTL port(2) |IIO| = 8 mA VDDIOx ≥ 2.7 V -0.4 VOH(3) Output high level voltage for an I/O pin 2.4 - VOL(3) Output low level voltage for an I/O pin |IIO| = 20 mA VDDIOx ≥ 2.7 V -1.3 VOH(3) Output high level voltage for an I/O pin VDDIOx-1.3 - VOL(3) Output low level voltage for an I/O pin |IIO| = 4 mA VDDIOx ≥ 1.62 V -0.45 VOH(3) Output high level voltage for an I/O pin VDDIOx-0.45 - VOL(3) Output low level voltage for an I/O pin |IIO| = 2 mA 1.62 V ≥ VDDIOx ≥ 1.08 V -0.35ₓVDDIOx VOH(3) Output high level voltage for an I/O pin 0.65ₓVDDIOx - VOLFM+ (3) Output low level voltage for an FT I/O pin in FM+ mode (FT I/O with "f" option) |IIO| = 20 mA VDDIOx ≥ 2.7 V -0.4 |IIO| = 10 mA VDDIOx ≥ 1.62 V -0.4 |IIO| = 2 mA 1.62 V ≥ VDDIOx ≥ 1.08 V -0.4 1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 17: Voltage characteristics, and the sum of the currents sourced or sunk by all the I/Os (I/O ports and control pins) must always respect the absolute maximum ratings ΣIIO. 2. TTL and CMOS outputs are compatible with JEDEC standards JESD36 and JESD52. 3. Guaranteed by design. |
