COP912C Datasheet | National Semiconductor

Description The COP912C COP912CH are members of the COP8TM 8-bit Micro Controller family They are fully static Microcontrollers fabricated using double-metal silicon gate micro CMOS technology These low cost Micro Controllers are plete microputers 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 MICROWl RETM serial I O a 16-bit timer counter with capture register and a multi-sourced interrupt Each I O pin has software selectable options to adapt the device to the specific application The device operates over voltage ranges from 2 3V to 4 0V (COP912C) and from 4 0V to 5 5V (COP912CH) High throughput is achieved with an efficient regular instruction set operating at a minimum of 2 ms per instruction rate CPU Instruction Set Features Instruction cycle time of 2 ms for COP912CH and 2 5 ms for COP912C Three multi-sourced interrupts servicing External Interrupt with selectable edge Timer interrupt Software interrupt Versatile and easy to use instruction set 8-bit Stack Pointer (SP) stack in RAM Two 8-bit Register Indirect Memory Pointers (B X) Fully Static CMOS Low current drain (typically k 1 m A) Single supply operation 2 3V to 4 0V or 4 0V to 5 5V Temperature range 0 C to a 70 C Key Features Development Support Lowest cost COP8 microcontroller 16-bit multi-function timer supporting PWM mode External event counter mode Input capture mode 768 bytes of ROM 64 bytes of RAM Emulation and OTP devices Real time emulation and full program debug offered by Meta Link Development System Applications Y Y Y Y Y Y Y Y Y I O Features Memory mapped I O Software selectable I O options (TRI-STATE Output Push-Pull Output Weak Pull-Up Input High Impedance Input) Schmitt trigger inputs on Port G MICROWIRE PLUSTM Serial I O Packages 20 DIP SO with 16 I O pins Electronic keys and switches Remote...
