Actually, since you mention both analog signals and servo control, and
you come from a 32-bit background, take a look at TI's C28xx family of
DSPs.

Watch out for line wrap!
16 analog channels for ADC, quadrature encoder inputs (if needed), and
up to 12 PWM outputs, can drive six brush DC motors or two 3-phase
motors simultaneously.
Has SPI built in, not I2C, but you might be able to do I2C with the
McBSP serial peripheral. Check the app notes.
