TMP86FS49AIUG

22.3 DC Characteristics

Note 1: Typical values show those at Topr = 25

°C and V

DD = 5 V.

Note 2: Input current (IIN3): The current through pull-up resistor is not included.

Note 3: IDD does not include IREF.

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 IDD (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. In SLOW1 mode, the difference

between the peak current and the average current becomes large.
