Caution

The pins mounted depend on the product. Refer to 1.3.1 30-pin products to 1.3.10 100-pin products.

Note 1.

Current flowing only to the real-time clock (excluding the operating current of the XT1 oscillator). The TYP. value of the

current value of the RL78/G14 is the sum of the TYP. values of either IDD1 or IDD2, and IRTC, when the real-time clock

operates in operation mode or HALT mode. The IDD1 and IDD2 MAX. values also include the real-time clock operating

current. However, IDD2 subsystem clock operation includes the operational current of the real-time clock.

Note 2.

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

Note 3.

Current flowing only to the watchdog timer (including the operating current of the low-speed on-chip oscillator).

The current value of the RL78/G14 is the sum of IDD1, IDD2 or IDD3 and IWDT when the watchdog timer operates in STOP

mode.

Note 4.

Current flowing only to the A/D converter. The current value of the RL78/G14 is the sum of IDD1 or IDD2 and IADC when the

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

Note 5.

Current flowing only to the D/A converter. The current value of the RL78/G14 is the sum of IDD1 or IDD2 and IADC when the

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

Note 6.

Current flowing only to the comparator circuit. The current value of the RL78/G14 is the sum of IDD1, IDD2 or IDD3 and ICMP

when the comparator circuit operates in the Operating, HALT or STOP mode.

Note 7.

Current flowing only to the LVD circuit. The current value of the RL78/G14 is the sum of IDD1, IDD2 or IDD3 and ILVI when

the LVD circuit operates in the Operating, HALT or STOP mode.

Note 8.

Current flowing only to the BGO. The current value of the RL78/G14 is the sum of IDD1 or IDD2 and IBGO when the BGO

operates in an operation mode.

Note 9.

A comparator and D/A converter are provided in products with 96 KB or more code flash memory.

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

Remark 2. fSUB: Subsystem clock frequency (XT1 clock oscillation frequency)

Remark 3. fCLK: CPU/peripheral hardware clock frequency

Remark 4. Temperature condition of the TYP. value is TA = 25 °C
