COP880C  
Microcontrollers  
General Description  
The following part numbers are pin count and tempera-  
ture variations of the COP880C: COP680C/COP681C/  
n High current outputs (8 pins)  
n Schmitt trigger inputs on Port G  
n MICROWIRE PLUS serial I/O  
n Packages:  
COP682C/COP881C  
COP981C/COP982C.  
/COP882C/COP980C/  
20 DIP/SO with 16 I/O pins  
28 DIP/SO with 24 I/O pins  
40 DIP, 36 I/O pins  
The COP880C devices are members of the COP8 microcon-  
troller 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 nec-  
essary to implement dedicated control functions in a variety  
of applications. Features include an 8-bit memory mapped  
44 PLCC, 36 I/O pins  
CPU/Instruction Set Features  
n 1 µs instruction cycle time  
n Three multi-source interrupts servicing  
External interrupt with selectable edge  
Timer interrupt  
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.  
Software interrupt  
n Versatile and easy to use instruction set  
n 8-bit Stack Pointer (SP)stack in RAM  
n Two 8-bit Register Indirect Data Memory Pointers  
(B and X)  
Key Features  
Fully Static CMOS  
n 16-bit multi-function timer supporting  
PWM mode  
<
n Low current drain (typically 1 µA)  
n Single supply operation: 2.5V to 6.0V  
n Temperature ranges: 0˚C to 70˚C, −40˚C to +85˚C,  
−55˚C to +125˚C.  
External event counter mode  
Input capture mode  
n 4 kbytes of ROM  
n 128 bytes of RAM  
Development Support  
n Emulation and OTP devices  
I/O Features  
n Memory mapped I/O  
n Software selectable I/O options (TRI-STATE®, Push-Pull,  
n Real time emulation and full program debug offered by  
MetaLink’s development system  
Weak Pull-Up Input, High Impedance Input)
