98 / 159 page  Electrical characteristics STM32G0C1xC/xE 98/159 DS13564 Rev 4 Input/output AC characteristics The definition and values of input/output AC characteristics are given in Figure 26 and Table 58, respectively. Unless otherwise specified, the parameters given are derived from tests performed under the ambient temperature and supply voltage conditions summarized in Table 24: General operating conditions. 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| = 2 mA for FT_c I/Os = 8 mA for other I/Os 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| = 2 mA for FT_c I/Os = 8 mA for other I/Os 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 All I/Os except FT_c |IIO| = 15 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| = 1 mA for FT_c I/Os = 3 mA for other I/Os VDDIOx ≥ 1.62 V -0.4 VOH(3) Output high level voltage for an I/O pin VDDIOx - 0.45 - 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| = 9 mA VDDIOx ≥ 1.62 V -0.4 1. The IIO current sourced or sunk by the device must always respect the absolute maximum rating specified in Table 21: 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. Table 58.
