43.7 Idle Current Consumption DC Electrical Specifications (85°C)

Table 43-8. Idle Current Consumption DC Electrical Specifications
DC Characteristics Standard Operating Conditions: VDDIO = VDDANA 1.9V to 3.6V (unless otherwise stated) Operating Temperature: -40°C ≤ TA ≤ +85°C for Industrial Temp
Param. No. Symbol Characteristics Clock/Freq Typ.(1) Max. Units Conditions
IPWR_1 IDD_IDLE (2) MCU IDD in IDLE mode w/LDO mode selected PLL 64 MHz 54 184 μA/MHz VDD = VDDANA = 3.3V
PLL 48 MHz 68 249
IPWR_3 MCU IDD in IDLE mode w/BUCK mode selected PLL 64 MHz 77 258
PLL 48 MHz 49 178
Note:
  1. Typical value measured during characterization across voltage and temperature.
  2. The test conditions are as follows:
    • All GPIO are input and pulled up.
    • All Peripherals disabled with PMD bits.
    • All PB clocks are divided by 16.
    • LPRC is set as LPCLK.
    • SOSC is disabled.
    • PMU 1 MHz clock is derived from FRC. FRC is divided by 8.
    • Cache is enabled and configured to wait time as 0xF.
    • WCM memories configured in Retention + NAP mode.
    • DSU is disconnected.
    • RF system OFF.
    • Entry to the Sleep mode is disabled and WFI instruction is executed.
    • On exit by External interrupt, verified RCON status to ensure system was in the IDLE mode.
  3. These parameters are characterized but not tested in manufacturing.
