Have no idea whther it is fast enough or not but it is an 8-bit 8-pin
MCU with serial interface. Using an internal oscillator which is
accurate enough to drive the UART in standard baudrates (we did some
tests up to 230.4 kbaud) the LPC903 or LPC908 could do the job. Both
are very similar but have different pinout.
Found this information on the Spoerle website:

And more here on Philips:

For 908 the info is here:

Don't ask me why the link is called 907 ;-)

Neither of these devices can be clocked externally so the max speed
you get is the internal oscillator. Neat little devices though.
