Probable mistake in K60 reference manual?

kaitav — Tue, 28 Jul 2015 06:07:06 GMT

Hi,

I was going through the USBDCD module description of K60 microcontroller reference manual and observed that on "Page 1453 of the K60P144M150SF3RM pdf, section 49.3.1 USB signal descriptions, Table 49-5" there is a typo in the second column against "dvdd" signal. Shouldn't this be 3.3V digital supply instead of 1.2V?

Thanks,

Kaitav

Hi Kaitav

The dvdd to the USB DCD is an internal signal. The main VDD is internally regulated down to 1.2V to power the digital logic in the chip including the digital supply for the USB DCD.

Have a great day,
Vicente
