I see Infineon release (early samples of) another iteration on their proven XC166 series, the XC2200 family :
"most of the XC226x?s instructions can be executed in just one machine cycle which requires 15ns at 66 MHz CPU clock. For example, shift and rotate instructions are always processed during one machine cycle independent of the number of bits to be shifted. Also multiplication and most MAC instructions execute in one single cycle. All multiple-cycle instructions have been optimized so that they can be executed very fast as well: for example, a 32-/16-bit division is started within 4 cycles, while the remaining cycles are executed in the background. Another pipeline optimization, the branch target prediction, allows eliminating the execution time of branch instructions if the prediction was correct."
Other features : Std 64/100/144 pin road map. 60 variants planned

The variablelength UART looks a nice way to solve framing problems with sending multiple bytes.
