Hi larwe,

the LPC932A1 is drop-in compatible to the LPC932B and by the way you
really want to use the A1, the first 932s had a problem that you could
easily overwrite/erase the internal programming routines. This is fixed
in the A1s

The LPC903 that you got can only run from internal RC oscillator but
still works with the build in UART. afaik, this is the smallest 8-bit
chip with a HW-UART.

Used both chip already, very nice low cost devices, you get 3.7 MIPS
our of them running from the IRC-oscillator, much more than you get
from a PIC and similar to the 4 MHz AVRs.

Also, others in the 'small with UART' category, are the upcomming LP213/LP214/LP216 from Atmel.
These also have _separate_ SPI ports, so you can do a SPI-UART in
a TSSOP package.
