Notes 1.  Current flowing to V

DD

. 

 2.  When high-speed on-chip oscillator and high-speed system clock are stopped. 

Current flowing only to the real-time clock (RTC) (excluding the operating current of the low-speed on-chip 

ocsillator and the XT1 oscillator).  The supply current of the RL78 microcontrollers is the sum of the values of 

either I

DD1

 or I

DD2

, 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.  I

DD2

 subsystem clock operation includes the 

operational current of the real-time clock. 

 4.  Current flowing only to the 12-bit interval timer (excluding the operating current of the low-speed on-chip 

ocsillator and the XT1 oscillator).  The supply current of the RL78 microcontrollers is the sum of the values of 

either I

DD1

 or I

DD2

, and I

IT

, 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.   

 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

, I

DD2

, or I

DD3

 and I

WDT

 when the watchdog 

timer is in operation. 

Current flowing only to the A/D converter.  The supply current of the RL78 microcontrollers is the sum of I

DD1

 or 

I

DD2

 and I

ADC

, I

AVREF

, I

ADREF

 when the A/D converter operates in an operation mode or the HALT mode.  

 

7.  Current flowing to the AV

DD

. 

 8.  Current flowing from the reference voltage source of A/D converter. 

 9.  Operation current flowing to the internal reference voltage. 

 10. Current flowing to the AV

REFP

. 

 11. Current flowing only to the LVD circuit.  The supply current of the RL78 microcontrollers is the sum of I

DD1

, I

DD2

 

or I

DD3

 and I

LVD 

when the LVD circuit is in operation. 

Current flowing only during data flash rewrite. 

Current flowing only during self programming. 

 14. For shift time to the SNOOZE mode, see 18.3.3  SNOOZE mode.
