203 / 227 page  DS13313 Rev 2 203/227 STM32H723xE/G Electrical characteristics 208 USB OTG_FS characteristics Unless otherwise specified, the parameters given in Table 114 for ULPI are derived from tests performed under the ambient temperature, fPCLKx frequency and VDD supply voltage summarized in Table 12: General operating conditions, with the following configuration: • Output speed is set to OSPEEDRy[1:0] = 11 • Capacitive load CL=20 pF • Measurement points are done at CMOS levels: 0.5VDD • IO Compensation cell activated. • VOS level set to VOS0 Refer to Section 6.3.16: I/O port characteristics for more details on the input/output characteristics. USB OTG_HS characteristics Unless otherwise specified, the parameters given in Table 114 for ULPI are derived from tests performed under the ambient temperature, fPCLKx frequency and VDD supply voltage summarized in Table 12: General operating conditions, with the following configuration: • Output speed is set to OSPEEDRy[1:0] = 11 • Capacitive load CL=20 pF • Measurement points are done at CMOS levels: 0.5VDD • IO Compensation cell activated. • VOS level set to VOS0 Refer to Section 6.3.16: I/O port characteristics for more details on the input/output characteristics. Table 113. USB OTG_FS electrical characteristics Symbol Parameter Condition Min Typ Max Unit VDD33US B USB transceiver operating voltage - 3.0(1) 1. The USB functionality is ensured down to 2.7 V. However, not all USB electrical characteristics are degraded in the 2.7 to 3.0 V voltage range. -3.6 V RPUI Embedded USB_DP pull-up value during idle - 900 1250 1600 Ω RPUR Embedded USB_DP pull-up value during reception - 1400 2300 3200 ZDRV Output driver impedance(2) 2. No external termination series resistors are required on USB_DP (D+) and USB_DM (D-); the matching impedance is already included in the embedded driver. Driver high and low 28 36 44 |
