On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 26. The MCU is placed
under the following conditions:
• At startup, all I/O pins are configured as analog inputs by firmware.
• All peripherals are disabled unless otherwise mentioned
• The given value is calculated by measuring the current consumption
– with all peripherals clocked off
– with one peripheral clocked on (with only the clock applied)
• The code is running from Flash memory and the Flash memory access time is equal to
3 wait states at 120 MHz
• Prefetch and Cache ON
• When the peripherals are enabled, HCLK = 120MHz, f
PCLK1
= f
HCLK
/4, and
f
PCLK2
=f
HCLK
/2
• The typical values are obtained for V
DD
= 3.3 V and T
A
= 25 °C, unless otherwise
specified.
