HD404639R Series
3. RD₀–RD₃ 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)
RD₂/COMP₂ at GND (0 V to 0.3 V)
RD₃/COMP₃ at GND (0 V to 0.3 V)
RE₀/VC_ref at GND (0 V to 0.3 V)
4. I , _SBY1 I_SBY2 and I_SBY3 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 GND (0 V to 0.3 V)
TEST at V_CC (V_CC –0.3 to V_CC)
5. These are the source currents when no I/O current is flowing.
Test conditions: Pins: RESET at GND (0 V to 0.3 V)
6. RAM data retention.
TEST at V_CC (V_CC –0.3 to V_CC)
D₁₃* at V_CC (V_CC –0.3 to V_CC) * Applies to HD407A4639R.
7. The reference voltage is the expected internal VC_ref voltage selected by the compare control
register (CCR: $016).
Example: when CCR = $2, reference voltage is 4/22 x V_CC.
8. Applies to HD40A4638R, HD40A4639R, HD407A4639R.
