1. Available peripherals depend upon package, STM32WB35xx features one SPI, no LCD, no TSC and two wakeup pins. See Table 2: STM32WB55xx and STM32WB35xx
devices features and peripheral counts for more details.
2. Typical current at VDD = 1.8 V, 25 °C. for STOPx, SHUTDOWN and Standby, else VDD = 3.3 V, 25 °C.
3. The Flash memory controller can be placed in power-down mode if the RF subsystem is not in use and all the program is run from the SRAM.
4. Flash memory programming is only possible in Range 2 voltage.
5. The SRAM1 and SRAM2 clocks can be gated off independently.
6. HSE (32 MHz) automatically used when RF activity is needed by the RF subsystem.
7. HSI16 (16 MHz) automatically used by some peripherals.
8. U(S)ART and LPUART reception is functional in Stop mode, and generates a wakeup interrupt on Start, Address match or Received frame event.
9. I2C address detection is functional in Stop mode, and generates a wakeup interrupt in case of address match.
10. SRAM1 and SRAM2b are OFF.
11. I/Os with wakeup from Standby/Shutdown capability: PA0, PC13, PC12, PA2, PC5.
12. I/Os can be configured with internal pull-up, pull-down or floating but the configuration is lost immediately when exiting the Shutdown mode.
