5V version: 2.7V to 5.5 V
(f(XIN)=16MHz, without wait, 4.2V to 5.5V,
f(XIN)=10MHz, with one wait, 2.7V to 5.5V)

f(XIN)=7MHz, without wait, 2.4V to 3.6V)
5V version: 4.2V to 5.5 V
Program/erase voltage
(f(XIN)=12.5MHz, with one wait,
f(XIN)=6.25MHz, without wait)
3V version: 2.7V to 3.6 V

12.0mA(Typ.), 21.25mA(Max.) (VCC=3V, f(XIN)=10MHz, square wave, no division, without wait)
40µA(Typ.) (VCC=3V, f(XCIN)=32kHz, square wave, without wait) [operate in RAM]
700µA(Typ.) (VCC=3V, f(XCIN)=32kHz, square wave, without wait) [operate in flash memory]
Note1: The boot ROM area contains a standard serial I/O mode control program which is stored in it when shipped from the factory.
This area can be erased and programmed in only parallel I/O mode.
Note2: Refer to recommended operating conditions about 5 V version. 3V version relationship between main clock oscillation
frequency and supply voltage are as follows.

Note4: A standard value in stop and wait modes do not depend on a kind of memory to have built-in and is the same class. Refer to
electric characteristic in VCC=3V.
