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 = VCC_DCDC = VBATT = 1.62 to 3.63 V

● VCC2 = 1.62 to 3.63 V for Standard Product

● VCC2 = 1.70 to 2.00 V for SiP Product

● AVCC0 = 1.62 to 3.63 V

● VCC_USB = VCC_USBHS = AVCC_USBHS = 3.0 to 3.6 V

● VREFH0/VREFH = 1.62 V to AVCC0

● VSS = VSS_DCDC = AVSS0 = VREFL0/VREFL = VSS_USB = VSS1_USBHS = VSS2_USBHS = 0 V

● VCC voltage is lower than 2.7 V : LVOCR.LVO0E = 1, otherwise LVOCR.LVO0E = 0

● VCC2 voltage is lower than 2.7 V : LVOCR.LVO1E = 1, otherwise LVOCR.LVO1E = 0

● Tj = Topj

When not specified otherwise, typical values are measured at room temperature of 25 ℃ and VCC = VCC_DCDC =

VCC_USB = VBATT = VCC_USBHS = AVCC_USBHS = AVCC0 = VREFH0 = VREFH = 3.3V

Figure 2.1 shows the timing conditions.

For example, P100

VOH = VCC/VCC2 × 0.7, VOL = VCC/VCC2 × 0.3

VIH = VCC/VCC2 × 0.7, VIL = VCC/VCC2 × 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.
