Why are chips used in electronic identity cards?

Why did Germany choose NXP's SmartMX chip in the new Electronic ID Card (see here) instead of having a more conventional solution, like an old credit-card-like approach? In fact, the question is more general: Why is the chip solution considered the…

Can an LPC1343 accept its initial program over USB?

The LPC13xx datasheet suggests some clock setup is necessary to use USB. Does the chip's built in boot loader make it possible to load the initial program over USB, or do the clock multipliers have to be configured with JTAG first?

LPC1343 double pin functions

I was looking to create a LPC1343 development board, but I noticed something odd. If you look at the pinout for this MCU you can see double functions for some pins. This is common, so you can program a pin to use for a particular function. But here…
