Note 1. Current flowing to VDD.
Note 2. When high speed on-chip oscillator and high-speed system clock are stopped.
Note 3. Current flowing only to the real-time clock (RTC) (excluding the operating current of the low-speed on-chip oscillator and
the XT1 oscillator). The supply current of the RL78 microcontrollers is the sum of the values of either I
DD1 or IDD2, and
I
RTC, when the real-time clock operates in operation mode or HALT mode. When the low-speed on-chip oscillator is
selected, I
FIL should be added. IDD2 subsystem clock operation includes the operational current of the real-time clock.
Note 4. Current flowing only to the 12-bit interval timer (excluding the operating current of the low-speed on-chip oscillator and
the XT1 oscillator). The supply current of the RL78 microcontrollers is the sum of the values of either I
DD1 or IDD2, and IIT,
when the 12-bit interval timer operates in operation mode or HALT mode. When the low-speed on-chip oscillator is
selected, I
FIL should be added.
Note 5. Current flowing only to the watchdog timer (including the operating current of the low-speed on-chip oscillator).
The supply current of the RL78 microcontrollers is the sum of I
DD1, IDD2, or IDD3 and IWDT when the watchdog timer is in
operation.
Note 6. Current flowing only to the A/D converter. The supply current of the RL78 microcontrollers is the sum of I
DD1 or IDD2 and
I
ADC when the A/D converter operates in an operation mode or the HALT mode.
Note 7. Current flowing only to the LVD circuit. The supply current of the RL78 microcontrollers is the sum of I
DD1, IDD2, or IDD3
and ILVD when the LVD circuit is in operation.
Note 8. Current flowing during programming of the data flash.
Note 9. Current flowing during self-programming.
Note 10. For shift time to the SNOOZE mode, see 20.3.3 SNOOZE mode.
