Notes 1. Total current flowing into VDD, including the input leakage current flowing when the level of the input pin is
fixed to V
DD or VSS. The values below the MAX. column include the peripheral operation current. However,
not including the current flowing into the A/D converter, LVD circuit, I/O port, and on-chip pull-up/pull-down
resistors and the current flowing during data flash rewrite.
2. During HALT instruction execution by flash memory.
3. When high-speed on-chip oscillator clock is stopped.
4. When high-speed system clock is stopped.
5. Not including the current flowing into the 12-bit interval timer and watchdog timer.
6. Relationship between operation voltage width, operation frequency of CPU and operation mode is as
follows.
HS(High speed main) mode: V
DD = 2.7 V to 5.5 V @1 MHz to 24 MHz
VDD = 2.4 V to 5.5 V @1 MHz to 16 MHz
LS(Low speed main) mode: V
DD = 1.8 V to 5.5 V @1 MHz to 8 MHz
Remarks 1. f
MX: High-speed system clock frequency (X1 clock oscillation frequency or external main system clock
frequency)
2. f
IH: high-speed on-chip oscillator clock frequency
3. Except temperature condition of the TYP. value is TA = 25°C, other than STOP mode
