USB characteristics

The STM32WB55xx and STM32WB35xx USB interface is fully compliant with the USB

specification version 2.0, and is USB-IF certified (for Full-speed device operation).

1. TA = -40 to 125 °C unless otherwise specified.

2. The STM32WB55xx and STM32WB35xx USB functionality is ensured down to 2.7 V, but the full USB

electrical characteristics are degraded in the 2.7 to 3.0 V voltage range.

3. Guaranteed by design.

4. 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.

JTAG/SWD interface characteristics

Unless otherwise specified, the parameters given in Table 98 and Table 99 are derived from

tests performed under the ambient temperature, fPCLKx frequency and supply voltage

conditions summarized in Table 24: General operating conditions, with the following

configuration:

 Capacitive load C = 30 pF

 Measurement points are done at CMOS levels: 0.5 ₓ VDD
