Re requirement for PWM output, ROM and RAM: I recently programmed an Intel 
8031 to run 8 (you can count 'em!) PWM outputs. This chip has 128 bytes of 
RAM (256 in the 8032), a serial port, and EPROM (in the 8751/8752). 

Now I have to admit that the PWM outputs were only at 40Hz, with 100 possible
duty cycles (--> 4KHz interrupt frequency) but it was what that job (running
small motors) demanded.
