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
DTMF 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. These are the source currents when no I/O current is flowing.
Test conditions: Pins: RESET at GND (0 V to 0.3 V)
TEST at V_CC (V_CC – 0.3 V to V_CC)
D₁₁ (V_PP) at V_CC (V_CC – 0.3 V to V_CC) for the HD4074629
5. The required voltage for RAM data retention.
