ı want to buy a nxp LPC43S50FET256 processor and ı made some research but I dont know whether lpc43s50 has already got bridge connections, ı also dont know for example whether ethernet is already connected or not I couldnt understand from the datasheet and there is not enough information about this processor so ı couldnt understand whether this is an only processor or are there some other part which has already connected to processor for example ethernet and some other ports. Exactly what ı mean is whether this is a processor or microprocessor board
This device actually has two processor cores and includes many peripherals including an Ethernet MAC. It is not a development board it's an IC. By the way, it has no on-chip flash.
Not wanting to be rude, but if you can't glean this from that datasheet, it sounds like a heck of an undertaking for you.
Why do you want to use this chip specifically?
