The LPC804 is a new low-end microcontroller from NXP in the LPC8xx range. The LPC804 is interesting, because so far it is the only LPC microcontroller which contains a Programmable Logic Unit (PLU), a miniature FPGA with 26 5-input lookup tables and 4 bits of state. Unfortunately NXP doesn't publish the timing parameters of this circuitry. You are supposed to use NXPs proprietary PLU configuration tool, which is available only for Microsoft Windows.

Here is a quick measurement of the speed of the LUTs in the PLU: Oscilloscope screen with delay measuments
