Parameter
Note 1: Typical values shown are Topr = 25°C and V
Note 2: I
Note 3: V
Note 4: In SLOW1 mode, the difference between the peak current and the average current becomes large.
Note 5: Each supply current in SLOW2 mode is equivalent to that in IDLE0, IDLE1 and IDLE2 modes.
Note 6: When a program operates in the flash memory or when data is being read from the flash memory, the flash memory
Note 7: If a write or erase is performed on the flash memory or a security program is enabled in the flash memory, an instantaneous
Note 8: The circuit of a power supply must be designed such as to enable the supply of a peak current. This peak current causes
