(min) in parallel

mandatory for OTG

0.1

µF and 1 µFto6.5 µF

in parallel

DESD

recommended for all

ESD-sensitive applications

IP4359CX4/LF; Wafer-Level Chip-Scale

Package (WLCSP); ESD IEC 61000-4-2

level 4;

±15 kV contact; ±15 kV air discharge

compliant protection

Rpullup

recommended; for applications

with an external VBUS supply

controlled by PSW_N

4.7 k

Ω (recommended)

maximum value is determined by the voltage

drop on PSW_N caused by leakage into

PSW_N and the external supply control pin

RRREF

mandatory in all applications

12 k

Ω± 1%

RVBUS

strongly recommended for

peripheral or external 5 V

applications only

Ω± 5%

RXTAL

required only for applications

driving a square wave into the

XTAL1 pin

47 k

Ω± 5 %

used to avoid ﬂoating input on the XTAL1 pin

XTAL

crystal is used

19.2 MHz

CL = 10 pF; RS < 220 Ω; CXTAL =18pF

CL = 10 pF; RS < 130 Ω; CXTAL =18pF

CSTCE26M0XK2***-R0[2]

CXTAL is not required

C(XTAL)SQ

required only for applications

driving a square wave into the

XTAL1 pin that has a DC offset

100 pF

used to AC couple the input square wave to

the XTAL1 pin
