Overview

COP880C Microcontrollers August 1996 COP880C Microcontrollers General Description The following part numbers are pin count and temperature variations of the COP880C: COP680C/COP681C/ COP682C/COP881C /COP882C/COP980C/ COP981C/COP982C.
The COP880C devices are members of the COP8 microcontroller family.
They are fully static parts, fabricated using double-metal silicon gate microCMOS technology.
This low cost microcontroller is a complete microcomputer containing all system timing, interrupt logic, ROM, RAM, and I/O necessary to implement dedicated control functions in a variety of applications.
Features include an 8-bit memory mapped architecture, MICROWIRE/PLUS™ serial I/O, a 16-bit timer/ counter with capture register and a multi-sourced interrupt.
Each I/O pin has software selectable options to adapt the device to the specific application.
The part operates over a voltage range of 2.
5 to 6.
0V.
High throughput is achieved with an efficient, regular instruction set operating at a 1 microsecond per instruction rate.
