If you can put all the analog stuff outside
(could be hard to get high speed 16 bit ADC in a micro)
then the AT91RM3400 could be good for the job.

32 bit ARM7 at 66 MHz executing from internal SRAM, loading from ext
dataflash
Multiple I/O
5 x USART
SPI
TWI (I2C compatible)
6 timers
low power

The AT91SAM7A3 will be the flash version of above with some 10 bit ADC.
