Electrical Characteristics

Unless otherwise specified, minimum and maximum values are guaranteed by either design simulation, characterization

results or test in production.

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*1 = AVCC0 = VCC_USB = 1.6 to 3.6 V, VREFH0 = 1.6 V to AVCC0

VSS = AVSS0 = VREFL0 = VSS_USB = 0 V, Ta = Topr

Note 1. The typical condition is set to VCC = 3.3 V.

Figure 2.1 shows the timing conditions.

For example, P300

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 measurement conditions of the timing specifications for each peripheral are recommended for the best peripheral

operation. However, make sure to adjust driving abilities for each pin to meet the conditions of your system.
