32-bit ARM Cortex-M0+ microcontroller
11.2 CoreMark data
The CoreMark scores serve as a guideline to select the best power mode for a given
application. To find the most suitable power mode, run the application in mode and
compare power consumption and performance.
Measured with Keil uVision v.4.72. Measured with Keil uVision v.4.60.
Conditions: Conditions: V

= 3.3 V; active mode; all peripherals except one UART and the SCTimer disabled in the
SYSAHBCLKCTRL register; internal pull-up resistors enabled; BOD disabled.
