128K flash is O.K.
16K RAM is probably too small. I would say that 64K RAM is a
reasonable minimum. Some things will be possible with 32K RAM. I think
with 16K RAM you are going to have problems.
Maybe take a look at the ATMEL AT91SAM7 family. There are devices with
256K Flash and 64K RAM with eCos support already in anoncvs. There are
also similar devices from Philips in there LPC family.
