Hello All,

In the data sheet for the LPC43xx, there is not much information on the recommended specification for the RTC crystal and external components to be used.

Could someone please specify the required information for this circuit? Crystal frequency, crystal equivalent series resistance, crystal drive level, external capacitor values.

Thank you!

/Fredric

Hi,

I suggest you to check the following report, this contains characterization results of crystals with LPC1700/LPC1800/LPC4300

Have a great day,
Sol
