COP840CJ/COP842CJ/COP940CJ/COP942CJ
8-Bit Microcontrollers with Multi-Input Wake-Up and
Brown Out Detector
General Description
The COP840CJ is a member of the COP8
feature family
8-bit microcontroller. It is a fully static Microcontroller, fabri-
cated using double-metal silicon gate microCMOS technol-
ogy. This low cost microcontroller is a complete microcom-
puter 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
serial
I/O,
a
16-bit
timer/counter
multi-sourced interrupt, Comparator, WATCHDOG
Timer,
Modulator/Timer, Brown out detection and Multi Input
Wake-up. Each I/O pin has software selectable options to
adapt the device to the specific application. The device oper-
ates over a voltage range of 2.5V–6.0V. High throughput is
achieved with an efficient, regular instruction set operating at
a 1 ms per instruction rate. Low radiated emissions are
achieved by gradual turn on output drivers and internal I
