hello folks,
on my custom board i use an f28027 with 48pins which dies directly after power on. it draws around an amp and gets very hot.
i have no idea why this happens because on my previous board with the 38 pin version everything is fine.
if anyone could give me tipps why this happens it would be nice. when someone needs any schematics just say it.
one confusing thing to me is that in the corresponding launchpad schematic the test pin is connected with ground and in the datasheet it says that the test pin must be left unconnected, also the pins x1 and x2 are a bit missleading. the launchpad doesnt have them connected to anything and the datasheet says that if i dont use a crystal x1 should be tight to ground.
