I am looking for small low cost processor ideally with 4 16 bit
capture on interrupt timers. Its to measure the minimum bit width of 4
RS232 sources, which can have a minimum bit width of 8.2uS. This has
to be done continuously with the results filtered etc with resulting
bit width converted to its corresponding baud rate and then an
equivalent 4 bit number which is output to a IO port. Therefore the
processor requires 20 I/O lines.

Any ideas etc would be appreciated

Thanks
