Note 1.

The listed currents are the total currents flowing into VDD, including the input leakage currents flowing when

the level of the input pin is fixed to VDD or VSS.

Regarding the values for main system clock operation, the TYP. value does not include the peripheral

operating current. The MAX. value includes the peripheral operating current, but does not include those

flowing into the A/D converter, comparator, capacitive touch sensing unit (CTSU), I/O port, and on-chip pull-

up/pull-down resistors.

Regarding the values for subsystem clock operation, the TYP. and MAX. values do not include the peripheral

operating current. However, in HALT mode, the current flowing into the RTC is included.

Regarding the values in STOP mode, the TYP. and MAX. values do not include the peripheral operating

current.

Note 2.

When the HALT instruction is executed from the flash memory.

Note 3.

The listed currents do not include the current flowing into real-time clock 2, the clock output/buzzer output

controller, 12-bit interval timer, and watchdog timer.

Note 4.

When the high-speed system clock and subsystem clock are stopped.

Note 5.

When the high-speed on-chip oscillator and subsystem clock are stopped.

Note 6.

16-pin, 20-pin, 24-pin, and 32-pin products only.

Note 7.

When the high-speed on-chip oscillator and high-speed system clock are stopped. When AMPHS1 = 1 (ultra-

low power consumption oscillation). However, not including the current flowing into real-time clock 2, the 12-

bit interval timer, watchdog timer, and capacitive touch sensing unit.
