Note 12. This current only flows to the D/A converter. The supply current of the RL78 microcontrollers is the sum of the values of

either IDD1 or IDD2, and IDAC, when the D/A converter is operating or in the HALT mode.

Note 13. This current only flows to the comparator. The supply current of the RL78 microcontrollers is the sum of IDD1, IDD2 or IDD3

and ICMP when the comparator is in operation.

Note 14. This current only flows to the LVD circuit. The supply current of the RL78 microcontrollers is the sum of IDD1, IDD2 or IDD3 and

ILVD when the LVD circuit is in operation.

Note 15. This current only flows during self-programming.

Note 16. This current only flows while the data flash memory is being rewritten.

Note 17. This current only flows into the SNOOZE mode sequencer. Note that the operating current of the low-speed on-chip

oscillator and the XT1 oscillator are not included. The supply current of the RL78 microcontrollers is the sum of either IDD1 or

IDD2, and ISMS, when the SNOOZE mode sequencer is operating or in the HALT mode.

Note 18. For shift time to the SNOOZE mode, see 27.3.3 SNOOZE mode in the RL78/L23 User’s Manual.

Note 19. The listed values apply when the SNOOZE mode sequencer is in normal operation equivalent to IDD1. They do not include

the current flowing into the peripheral functions other than the SNOOZE mode sequencer.

Note 20. This current is added to the supply current in the HALT mode when the setting of RTCLPC is 0 in the STOP mode, or when

the setting of RTCLPC is 0 with the subsystem clock X (fSX) selected as the CPU clock, while the subsystem clock X (fsx) is

oscillating.

Note 21. This current is added to the supply current when the output voltage control port is set.

Note 22. This current does not include the current flowing into the I/O port pins.

Note 23. This current flows to VDD.

Note 24. This current only flows to the LCD controller/driver. The supply current of the RL78 microcontrollers is the sum of the supply

current (IDD1 or IDD2) and LCD operating current (ILCD1, ILCD2, or ILCD3) when the LCD controller/driver is operating while the

MCU is operating or in the HALT mode. It does not include the current flowing into the LCD panel. The values in the Typ. and

Max. columns apply under the following conditions.

• Setting 20 pins as the segment function and blinking all

• Selecting fSUB when LCD clock = 128 Hz (LCDC0 = 07H)

• Setting four time slices and 1/3 bias

Note 25. This current does not include the current flowing into the external division resistor when the external resistance division

method is in use.

Note 26. In addition to these conditions, VL2 (Max.) + 0.1 V

≤ VDD must be satisfied. For details, see 2.6.8.2 Internal voltage

boosting method.

Remark 1. fIL: Low-speed on-chip oscillator clock frequency

Remark 2. fSX: Subsystem clock X frequency

Remark 3. fCLK: CPU/peripheral hardware clock frequency

Remark 4. The typical value for the ambient operating temperature (TA) is +25°C unless otherwise specified.
