Parameter
Note 1: Typical values shown are Topr
Note 2: I
Note 3: V
Note 4: When performing a write or erase on the flash memory or activating a security program in the flash memory, make sure
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 oper-
Note 8: If a write or erase is performed on the flash memory or a security program is enabled in the flash memory, an instanta-
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
that the operating temperature Topr is within the range 10qC to 40qC. If the temperature is outside this range, the result-
