Electrical Characteristics

Supported peripheral functions and pins differ from one product name to another.

Unless otherwise specified, the electrical characteristics of the MCU are defined under the following conditions:

● VCC = AVCC0 =2.7 to 3.6

● 2.7 ≤ VREFH0/VREFH ≤ AVCC0

● VSS = AVSS0 = VREFL0/VREFL = 0 V

● Ta = Topr

Figure 2.1 shows the timing conditions.

For example, P100

VOH = VCC × 0.7, VOL = VCC × 0.3

VIH = VCC × 0.7, VIL = VCC × 0.3

Load capacitance C = 30 pF

Input or output timing measurement conditions

The recommended measurement conditions for the timing specification of each peripheral provided are for the best

peripheral operation. Make sure to adjust the driving abilities of each pin to meet your conditions.
