DC CHARACTERISTICS Standard Operating Conditions: VDDREG=VDDIO=AVDD 1.71V to 3.6V (unless otherwise stated)

Operating temperature:

-40°C ≤ TA ≤ +85°C for Industrial
Param. No. Symbol Characteristics Clock/Freq Power Pin Typ. (1) Max. Units Conditions
IPWR_1 IDD_IDLE (2) MCU IDD in IDLE mode PLL_120_Mhz VDDIO = AVDD = 3.3V 2 2 mA PLL runs at 120 MHz, uses XOSC with 48 MHz crystal as reference clock
IPWR_3 VDDREG = 3.3V 18 60 mA
IPWR_5 DFLL _48_MHz VDDIO = AVDD = 3.3V 2 2 mA DFLL in open loop
IPWR_7 VDDREG = 3.3V 7 48 mA
IPWR_9 XOSC _48_MHz VDDIO = AVDD = 3.3V 2 2 mA 48 MHz crystal
IPWR_11 VDDREG = 3.3V 7 49 mA
Note:
  1. Typical values at 25°C only.
  2. Conditions:
    • No peripheral modules are operating (i.e. all peripherals inactive)
    • APB Peripheral bus clocks: default settings after reset
    • CMCC Cache disabled
    • MCU is running on Flash with automatic wait state
    • VREG_USB 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
