General Description  
The COP8780C, COP8781C and COP8782C are members  
Y
MICROWIRE/PLUS serial I/O

Packages:  
of the COPSTM 8-bit microcontroller family. They are fully  
Ð 44 PLCC, OTP, Emulates COP880C, 36 I/O pins  
static microcontrollers, fabricated using double-metal, dou-  
Ð 40 DIP, OTP, Emulates COP880C, 36 I/O pins  
ble poly silicon gate microCMOS EPROM technology.  
Ð 28 DIP, OTP, Emulates COP820C/840C/881C,  
These devices are available as UV erasable or One Time  
24 I/O pins  
Programmable (OTP). These low cost microcontrollers are  
Ð 20 DIP, OTP, Emulates COP822C/842C, 16 I/O pins  
complete microcomputers containing all system timing, in-  
Ð 28 SO, 20 SO, OTP  
terrupt logic, EPROM, RAM, and I/O necessary to imple-  
Ð 44 LDCC, UV Erasable  
ment dedicated control functions in a variety of applications.  
Ð 40 CERDIP, 28 CERDIP, 20 CERDIP, UV Erasable  
Features include an 8-bit memory mapped architecture, MI-  
CROWIRE/PLUSTM serial I/O, a 16-bit timer/counter with  
associated 16-bit autoreload/capture register, and a multi-  
sourced interrupt. Each I/O pin has software selectable op-  
tions to adapt the device to the specific application. These  
devices operate over a voltage range of 4.5V to 6.0V. An  
efficient, regular instruction set operating at a 1 ms instruc-  
tion cycle rate provides optimal throughput.
