C and V
DD
= 5 V.
Note 2: Input current (I
IN3
): The current through pull-up resistor is not included.
Note 3: I
DD
does not include I
REF
.
Note 4: The supply currents of SLOW2 and SLEEP2 modes are equivalent to those of IDLE0, IDLE1 and IDLE2 modes.
Note 5: When a program is executing in the flash memory or when data is being read from the flash memory, the flash memory
operates in an intermittent manner, causing peak currents in the operation current, as shown in Figure 22-1.
In this case, the supply current I
DD
(in NORMAL1, NORMAL2 and SLOW1 modes) is defined as the sum of the average
peak current and MCU current.
Note 6: When designing the power supply, make sure that peak currents can be supplied. The internal supply voltage of this
device may be changed by this peak current. Thus, it needs a bypass capacitor (about 0.1
µ
F ) near its power terminal to
stabilize its operation. In SLOW1 mode, the difference between the peak current and the average current becomes large.
Note 7: If a write or erase is performed on the flash memory or a security program is enabled in the flash memory, an instanta-
neous peak current flows, as shown in Figure 22-2.
