Hi, anybody knows what is the error of the 1khz lpo oscillator? If yes, are there any documents?

Thank you

Hi Stefano,

Digging some more about this, and found this:

http://www.freescale.com/files/32bit/doc/data_sheet/KL25P80M48SF0.pdf

Page 8, Table 6:

If I read this correctly, then it says that the possible error indeed is +/- 10%.

I'm using the LPO 1kHz clock for my low power application with LLS (IoT: FreeRTOS Down to the Micro Amps | MCU on Eclipse), and I typically have an error of about 1%.

Thanks Erich, in fact I have a 0.8% error but I expect something official from freescale.
