191 / 228 page  DS14540 Rev 1 191/228 STM32H523xx Electrical characteristics 197 Figure 53. I2S master timing diagram (Philips protocol)(1) 1. LSB transmit/receive of the previously transmitted byte. No LSB transmit/receive is sent before the first byte. USB full speed (FS) characteristics The USB interface is fully compliant with the USB specification version 2.0. Table 111. USB DC electrical characteristics Symbol Parameter Conditions Min(1) Typ Max(1) Unit VDD USB full speed transceiver operating voltage - 3.0(2) -3.6 V VDI(3) Differential input sensitivity Over VCM range 0.2 - - V VCM(3) Differential input common mode range Includes VDI range 0.8 - 2.5 VSE(3) Single ended receiver input threshold - 0.8 - 2.0 VOL Static output level low RL of 1.5 kΩ to 3.6 V(4) -- 0.3 V VOH Static output level high RL of 15 kΩ to VSS(4) 2.8 - 3.6 RPD(3) Pull down resistor on PA11, PA12 (USB_DP/DM) VIN = VDD 14.25 - 24.8 kΩ RPU(3) Pull-up resistor on PA12 (USB_DP) VIN = VSS, during idle 0.9 1.25 1.575 Pull-up resistor on PA12 (USB_DP) VIN = VSS during reception 1.425 2.25 3.09 1. All the voltages are measured from the local ground potential. 2. The USB full speed transceiver functionality is ensured down to 2.7 V but not the full USB full speed electrical characteristics, which are degraded in the 2.7-to-3.0 V VDD voltage range. 3. Specified by design - Not tested in production. |
