Notes 1. Total current flowing into V
DD, including the input leakage current flowing when the level of the input pin is
fixed to VDD or VSS. The values below the MAX. column include the peripheral operation current. However,
not including the current flowing into the watchdog timer, A/D converter, I/O port, and on-chip pull-up/pull-
down resistors.
2. During HALT instruction execution by flash memory.
3. When the high-speed on-chip oscillator is stopped.
4. Current flowing only to the watchdog timer (including the operating current of the low-speed on-chip
oscillator). The current value of the RL78 microcontrollers is the sum of I
DD1, IDD2 or IDD3 and IWDT when the
watchdog timer operates.
5. Current flowing only to the A/D converter. The current value of the RL78 microcontrollers is the sum of I
DD1
or IDD2 and IADC when the A/D converter operates in an operation mode or the HALT mode.
Remarks 1. f
IL: Low-speed on-chip oscillator clock frequency
2. fIH: High-speed on-chip oscillator clock frequency
3. Temperature condition of the TYP. value is T
A = 25°C
