'''Identification talk'''<br>
The logo is from microchip manufacturer, and they has a 463x series, but by looking at the [http://ww1.microchip.com/downloads/en/devicedoc/ds-22096a.pdf datasheet] the pinout doesnt matches and his features seems to be excesive for the PS3, it could be a component manufactured exclusivelly for sony
 
There are reports of the same component labeled '''044 463A'''... so the numbers at top doesnt matters (<@eussNL_> 036 / 044 / 229 etc. seems to suggest date/week code (2010 week 36, 2010 week 44, 2012 week 29 etc))
 
'''Notes'''<br>
The page needs to be renamed anyway so feel free to write here, it can be cleaned up later
