2. Electrical Characteristics

Electrical Characteristics

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

VCC*1 = AVCC0 = VCC_USB*2 = VCC_USB_LDO*2 = VCC_RF = AVCC_RF = 1.8 to 3.6V, VREFH0 = 1.8 to

AVCC0, VBATT = 1.8 to 3.6V, VSS = AVSS0 = VREFL0 = VSS_RF = VSS_USB = 0V, Ta = Topr.

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

Note 2. When USBFS is not used.

Figure 2.1 shows the timing conditions.

Input or output timing measurement conditions

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

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

Each function pin used for the same function must select the same drive ability. If the I/O drive ability of each function

pin is mixed, the AC specification of each function is not guaranteed.

For example P100

VOH = VCC × 0.7, VOL = VCC × 0.3

VIH = VCC × 0.7, VIL = VCC × 0.3

Load capacitance C = 30 pF
