45 / 67 page ![]() STM32F103xx Electrical characteristics 45/67 Output voltage levels Unless otherwise specified, the parameters given in Table 30 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 7. Table 30. Output voltage characteristics Symbol Parameter Conditions Min Max Unit VOL (1) 1. The IIO current sunk by the device must always respect the absolute maximum rating specified in Table 5 and the sum of IIO (I/O ports and control pins) must not exceed IVSS. Output low level voltage for an I/O pin when 8 pins are sunk at same time TTL port IIO = +8 mA 2.7 V < VDD < 3.6 V 0.4 V VOH (2) 2. The IIO current sourced by the device must always respect the absolute maximum rating specified in Table 5 and the sum of IIO (I/O ports and control pins) must not exceed IVDD. Output high level voltage for an I/O pin when 4 pins are sourced at same time VDD–0.4 VOL (1) Output low level voltage for an I/O pin when 8 pins are sunk at same time CMOS port IIO =+ 8mA 2.7 V < VDD < 3.6 V 0.4 V VOH (2) Output high level voltage for an I/O pin when 4 pins are sourced at same time 2.4 VOL (1) Output low level voltage for an I/O pin when 8 pins are sunk at same time IIO = +20 mA 2.7 V < VDD < 3.6 V 1.3 V VOH (2) Output high level voltage for an I/O pin when 4 pins are sourced at same time VDD–1.3 VOL (1) Output low level voltage for an I/O pin when 8 pins are sunk at same time IIO = +6 mA 2 V < VDD < 2.7 V 0.4 V VOH (2) Output high level voltage for an I/O pin when 4 pins are sourced at same time VDD–0.4 |
