I Have a TomTom 510 which has 2 blown IC's. I have found the LTQT IC on eBay. I can't read what is written on the 2nd IC (it's burnt out) but U16 is printed on the board. From what I can see with a magnifying glass, it says "64TI", I can't find this anywhere on the internet. I need to find the full number/model of this IC. Can anyone help?

Thanks
