LPC55S2x/LPC552x

32-bit ARM Cortex-M33 microcontroller

[6] Transparent analog pad.

[7] Optional bypass mode is supported, xtal32M_P can be driven by an external clock with restrictions in terms of drive level. See: Section

13 “Application information”.

[8] The corresponding VBUS must be connected to supply voltage when using the USB peripheral. USB0_VBUS is not 5 V tolerant pin and

is tolerant up to 3.6 V only when the VDD is at operating level (minimum: 1.8 V). USB1_VBUS is 5 V tolerant pin regardless if the VDD

supply is present or not.

[9] Main battery supply: Star connection at application level (PCB)..

[10] If the USB1_3V3 pin is not using the same supply as the VBAT_PMU pin, the application should ensure the supply on USB1_3V3 does

not drop below 2.8 V. If the USB1_3V3 pin is using separate supply and this voltage unexpectedly drops below 2.8 V, the USB PHY can

go into unknown state causing USB transactions (R/W) to hang. In this case, the application can detect this event with a time-out and

would have to recover by performing a USB reset.

[11] The JTAG functions TRST, TCK, TMS, TDI, and TDO are selected by hardware when the part is in boundary scan mode. The JTAG

functions cannot be used for debug mode.

[12] Optional bypass mode is supported, xtal32K_P can be driven by an external clock with restrictions in terms of drive level See: Section

13 “Application information”.
