hello guys, i need to replace a pic 24Hj256gp610 by pic 24ep512gu810 so can u help me about the pin equivalence specially the digital communication pin of SPI and UARTs. thanks for help
Actually the data sheets ARE very detailed, especially with regard to what signals are on what pins.
What you are missing is that the pic24ep512gu810 has PPS (Peripheral Pin Select) which allows you to map the input and output signals of various peripherals to the pins that are labelled 'RPn' (input or output) or 'RPIn' (input only).
I suggest that you read Section 11.4 of the pic24ep512gu810 data sheet.
Whether or not this will allow the pic24ep512gu810 to be a pin-for-pin replacement is something you will need to work out by looking at whether the required pin is also labelled as a PPS pin taking into account that the RPIn pins are input only.

From time to time I read something like this...
But where do all the other designers have their informations from, if not from the datasheet?
Usually the datasheets are very detailed, but sometimes they refer to additional documents, like application notes, design notes example designs, package informations and so on.
At least at the device related internet sites there should be all the links to the informations and forums.
But for sure the manufacturers don't hide important informations, and there are no "secret channels" to manufacture's informations..
