Additional Details:
The COP8784EGN-X typically operates at a clock frequency of several MHz. The EGN likely refers to the package type. The amount of EPROM and RAM varies depending on the specific version of the microcontroller. Datasheets will detail the number of I/O pins, the serial communication protocol supported, and interrupt sources. Programming is often done using assembly language. Like other older microcontrollers, it is often replaced with newer, more feature-rich devices in new designs, but may still be present in existing systems.
