Notes

1. Current flowing only to the watchdog timer. The maximum specification of IDD1, IDD2 and IDD3 include IWDT.

2. Current flowing only to the A/D converter. The current value of the RL78/D1A is the sum of IDD and IADC

when the A/D converter operates.

3. Current flowing only to the LCD controller/driver circuit. The current value of the RL78/D1A is the sum of IDD

and ILCD when the LCD controller/driver circuit operates.

4. Current flowing only to the ZPD circuit. The current value of the RL78/D1A is the sum of IDD and IZPD when

the ZPD circuit operates.
