DC Characteristics
*8
Measured under conditions without load. (Pull-up/pull-down resistors are unconnected.)
- The supply current during operation, IDD1,IDD2 are measured under the following condi
tions :
After all I/O pins are set to input mode and the oscillation is set to <NORMAL mode>,
the MMOD pin is at VSS level, the input pins are at VDD level, and a 20 MHz(8.39 MHz)
square wave of VDD and VSS amplitudes is input to the OSC1 pin.
- The supply current during operation, IDD3, 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 at VSS level, the input pins are at VDD level, and a 32.768 kHz square wave of
VDD and VSS amplitudes is input to the XI pin.
- The supply current during HALT1 mode, IDD4, IDD5 are measured under the following condi
tions :
After all I/O pins are set to input mode and the oscillation is set to <HALT mode>, the
MMOD pin is at VSS level, the input pins are at VDD level, and an 32.768 kHz square wave of
VDD and VSS amplitudes is input to the XI pin.
- The supply current during STOP mode, IDD6, is measured under the following conditions :
After the oscillation is set to <STOP mode>, the MMOD pin is at VSS level, the input pins are
at VDD level, and the OSC1 and XI pins are unconnected.
- For 84 pin QFP, above conditions are fulfilled when automatic reset function is not used.
