Electrical Characteristics
1-5-3 DC Characteristics
*1 Measured under conditions of Ta=25 °C, without load.
- The supply current during operation, IDD1(IDD2), is measured under the following conditions:
After all I/O pins are set to input mode and the oscillation is set to <NORMAL mode>, the
MMOD pin is connected to VSS level, the input pins are connected to VDD level, and a 20 MHz
(8.39 MHz) square wave of VDD and VSS amplitude is input to the OSC1 pin.
- The supply current during operation, IDD3(IDD4), is measured under the following conditions:
After all I/O pins are set to input mode and the oscillation is set to <SLOW mode>, the MMOD pin
is connected to VSS level, the input pins are connected to VDD level, and a 32.768 kHz square wave
of VDD and VSS amplitude is input to the XI pin.
- The supply current during HALT mode, IDD5(IDD6), is measured under the following conditions:
After all I/O pins are set to input mode and the oscillation is set to <HALT mode>, the MMOD pin
is connected to VSS level, the input pins are connected to VDD level and an 32.768 kHz square wave
of VDD and VSS amplitude is input to the XI pin.
- The supply current during STOP mode, IDD7(IDD8), is measured under the following conditions:
After the oscillation is set to <STOP mode>, the MMOD pin is connected to VSS level, the input pins
are connected to VDD level, and the OSC1 and XI pins are unconnected.
