1 / 36 page  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 with capture register, a 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 CC filters on the chip logic and crystal oscillator. Features n Multi-Input wake-up (on the 8-bit Port L) n Brown out detection n Analog comparator n Modulator/Timer (high speed PWM timer for IR transmission) n 16-bit multi-function timer supporting — PWM mode — External event counter mode — Input capture mode n Quiet design (low radiated emissions) n Integrated capacitor for the R/C oscillator n 2048 bytes of ROM n 128 bytes of RAM n Memory mapped I/O n Software selectable I/O options (TRI-STATE®, push-pull, weak pull-up input, high impedance input) n High current outputs (8 pins) n Schmitt trigger inputs on Port G n MICROWIRE/PLUS™ serial I/O n Packages: 20 DIP/SO with 16 I/O pins 28 DIP/SO with 24 I/O pins n 1 µs instruction cycle time n Three multi-source interrupts servicing — External interrupt with selectable edge — Timer interrupt — 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) Fully Static CMOS 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 Development Support n Emulation and OTP devices n Real time emulation and full program debug offered by MetaLink’s development system TRI-STATE® is a registered trademark of National Semiconductor Corporation.
