Note 1: Typical values shown are Topr = 25°C and VDD = 3.0 V, unless otherwise specified.
Note 2: IDD does not include IREF. It is the electrical current in the state in which the peripheral circuitry has been operated.
Note 3: VIN : The input voltage on the pin except MODE pin, VMODE : The input voltage on the MODE pin
Note 4: When performing a write or erase on the flash memory or activating a security program in the flash memory, make sure
that the operating temperature Topr is within the range 10°C to 60°C. If the temperature is outside this range, the resultant
performance cannot be guaranteed.
Note 5: In SLOW1 mode, the difference between the peak current and the average current becomes large.
Note 6: Each supply current in SLOW2 mode is equivalent to that in IDLE0, IDLE1 and IDLE2 modes.
Note 7: When a program operates in the flash memory or when data is being read from the flash memory, the flash memory
operates intermittently, and a peak current flows, as shown in Figure 25-4. In this case, the supply current IDD (in NOR- MAL1, NORMAL2 and SLOW1 modes) is defined as the sum of the average peak current and MCU current.
Note 8: If a write or erase is performed on the flash memory or a security program is enabled in the flash memory, an instantaneous
Note 9: The circuit of a power supply must be designed such as to enable the supply of a peak current. This peak current causes
the supply voltage in the device to fluctuate. Connect a bypass capacitor of about 0.1 μF near the power supply of the
device to stabilize its operation.
