132 / 231 page  Electrical characteristics STM32H533xx 132/231 DS14539 Rev 1 All I/Os are CMOS and TTL compliant (no software configuration required). Their characteristics cover more than the strict CMOS technology or TTL parameters. The coverage of these requirements for FT I/Os is shown in Figure 20. Figure 20. VIL/VIH for all I/Os except BOOT0 Output driving current The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or source up to ±20 mA (with a relaxed VOL/VOH). In the user application, the number of I/O pins that can drive current must be limited to respect the absolute maximum rating specified in Section 5.2. In particular: • The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating ΣIVDD (see Table 18). • The sum of the currents sunk by all the I/Os on VSS plus the maximum Run consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating ΣIVSS (see Table 18). Output voltage levels Unless otherwise specified, the parameters given in Table 58 and Table 60 are derived from tests performed under ambient temperature and VDD supply voltage conditions summarized in Table 20. All I/Os are CMOS and TTL compliant. |
