Note:
  1. Conditions:
    • Single supply mode
    • No peripheral modules are operating (i.e., all peripherals inactive)
    • MCK all peripherals clock masked except SUPC, RSTC, RTC, RTT, WDT, PMC, EFC, CORETEX FPU, and RSWDT
    • Core cache enable
    • Flash Wait State (FWS) in EEFC_FMR is adjusted depending on core frequency
    • I/Os are inactive input mode with input trigger disabled
    • All clock generation sources disabled unless otherwise specified
    • WDT, RSWDT, RTCC, CFD Clock Fail Detect disabled
    • µA/MHz varies over temperature. Worst case is given by maximum.
  2. MCU Running CoreMark® Test Suite.

Operating CONDITIONS

  • VDDIO = 3.3V
  • PLLA enabled 300 MHz
  • Main Crystal OSC used as PLL reference
  • MCK = 150 MHz
