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. FEATURES • CMOS technology • Full 68000 software compatibility • 32-bit internal structure • 16-bit internal data transfer • 8-bit access to external ROM/RAM • External addressing range 16 Mbytes for ROM and 16 Mbytes for RAM • Unused address pins can be used as quasi-bidirectional ports • On-chip address decoder for ROM/RAM • 8 edge triggered programmable interrupts that can also be used as quasi-bidirectional ports • Reset control • Built-in clock generator • 2 fully independent fast I2C-bus serial interfaces • UART serial interface (4 modes) • 3 fully independent 16-bit timers • Watchdog timer • 8-bit quasi-bidirectional port, 4-bits with high drive capability • EMC optimized layout and pinning • 64-pin QFP package
