Note:
  1. Typical values at 25°C only.
  2. Conditions:
    • VDDIO/ANA = 3.3V. VDDREG = 1.8V
    • No peripheral modules are operating (i.e., all peripherals except RTC inactive)
    • CPU frequency = 300 MHz
    • BMX clock = CPU frequency / 2
    • APB Peripheral bus clocks: default settings after reset
    • Arm-M7 Cache disabled
    • MCU is running on Flash with automatic wait state
    • VREG_PLL enabled
    • VREG_USB0/VREG_USB1 disabled
    • I/Os are inactive input mode with input trigger disabled
    • All clock generation sources disabled unless otherwise specified
    • WDT, CFD Clock Fail Detect disabled
