COP820CJ/COP822CJ/COP823CJ 8-Bit Microcontroller
with Multi-Input Wake Up and Brown Out Detector
General Description
The COP820CJ is a member of the COP8
TM
8-bit Microcon-
troller family. It is a fully static Microcontroller, 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
TM
serial I/O, a 16-bit
timer/counter with capture register, a multi-sourced inter-
rupt, Comparator, WATCHDOG
TM
Timer, Modulator/Timer,
Brown out protection and Multi-Input Wakeup. Each I/O pin
has software selectable options to adapt the device to the
specific application. The device operates over a voltage
range of 2.5V to 6.0V. High throughput is achieved with an
efficient, regular instruction set operating at a 1
m
s per in-
struction rate.
