at absolute maximum ratingsDescriptionThe COP87L84RG is a member of the COP8TM OTP microcontroller family. It is pin and software compatible to the mask ROM COP888EG product family.
COP87L84RG is a fully static part, fabricated using double-metal silicon gate microCMOS technology. COP87L84RG Features include an 8-bit memory mapped architecture, MICROWIRE/PLUSTM serial I/O, three 16-bit timer/counters supporting three modes (Processor Independent PWM generation, External Event counter, and Input Capture mode capabilities), full duplex UART and two comparators. Each I/O pin has software selectable configurations. The devices operates over a voltage range of 2.7V to 5.5V. High throughput is achieved with an efficient, regular instruction set operating at a maximum rate of 1 ms per instruction.
