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 ms per in-
struction rate
