Notes: 1. Excludes current flowing through pull-up MOS and output buffers.
2. I_CC is the source current when no I/O current is flowing while the MCU is in reset state.
Test conditions:
MCU: Reset
Pins: RESET, TEST at GND
D₀–D₅, R0–R3 at V_CC
3. I_SBY is the source current when no I/O current is flowing while the MCU timer is operating.
Test conditions:
MCU: I/O reset
Standby mode
Pins:
RESET at V_CC
TEST at GND
D₀–D₅, R0–R3 at V_CC
4. Applies to the HD404394 series and HD4074344.
5. Applies to the HD404344R series.
6. The current in case of excluding the current through A/D converters ladder resistance (flag I_AOF is
set to “1”). Circuit structure and circuit constants of oscillator circuit is the following condition.
