GENERAL DESCRIPTION

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.
