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 GND (0 to 0.3V)
TEST at V_CC (V_CC –0.3 to V_CC)
3. RD₀, RD₁ pins are in analog input mode when no I/O current is flowing.
Test conditions: MCU: DTMF does not operate
Pins: RD₀/COMP₀ at GND (0 V to 0.3 V)
RD₁/COMP₁ at GND (0 V to 0.3 V)
RE₀/VC_ref at GND (0 V to 0.3 V)
4. 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 does not operate
Standby mode
Pins: RESET at V_CC (V_CC –0.3 to V_CC)
TEST at V_CC (V_CC –0.3 to V_CC)
5. The current dissipation is in proportion to f_OSC while the MCU is operating or is in standby mode.
The current dissipation when f_OSC = F MHz is given by the following equation: Maximum value
(f_OSC = F MHz) = F/4 X maximum value (f_OSC = 4 MHz)
6. These are the source currents when no I/O current is flowing.
Test conditions:
Pins:
RESET at V_CC (V_CC –0.3 to V_CC)
TEST at V_CC (V_CC –0.3 to V_CC)
D₁₃ at V_CC (V_CC –0.3 to V_CC)*
Note: * Applies to HD4074654.
7. RAM data retention.
