32-bit ARM Cortex-M3 microcontroller
9.5 Peripheral power consumption
The supply current per peripheral is measured as the difference in supply current between
the peripheral block enabled and the peripheral block disabled in the SYSAHBCLKCFG or
PDRUNCFG (for analog blocks) registers. All other blocks are disabled in both registers
and no code is executed. Measured on a typical sample at Tamb =25
°C. Unless noted
otherwise, the system oscillator and PLL are running in both measurements.
The supply currents are shown for system clock frequencies of 12 MHz, 48 MHz, and
72 MHz.
