The P90CE201 is a member of the P9XCXXX family of
highly integrated 16-bit microcontrollers for use in a wide
variety of applications. It is fully software compatible with
the 68070/68000. The complete set of system functions
available on the chip results in reduced system cost.
Additionally, its modular design concept permits future
extension to the family.
