Notes: 1. Output buffer current is excluded.
2. I_CC1 and I_CC2 are the source currents when no I/O current is flowing while the MCU is in reset
state.
Test conditions:
MCU: Reset
Pins: RESET at V_CC (V_CC – 0.3 V to V_CC)
TEST at V_CC (V_CC – 0.3 V to V_CC)
3. I_SBY1 and I_SBY2 are the source currents when no I/O current is flowing while the MCU timer is
operating.
Test conditions:
MCU: I/O reset
Serial interface stopped
Standby mode
Pins: RESET at GND (0 V to 0.3 V)
TEST at V_CC (V_CC – 0.3 V to V_CC)
4. Applies to HD404448 and HD404449.
5. Applies to HD4074449.
6. These are the source currents when no I/O current is flowing.
Test conditions:
Pins: RESET at GND (0 V to 0.3 V)
7. RAM data retention.
