The Mitsubishi M5M80C85AFP-2 is a CMOS version of the Intel 8085 microprocessor. The 8085 is an 8-bit microprocessor that was widely used in the 1980s. Mitsubishi produced this as a second-source manufacturer, offering a CMOS version (indicated by the 'C' in the part number) for lower power consumption. The 'AFP' likely refers to the package type, and the '-2' likely signifies a specific speed grade or revision.

Additional Details

The M5M80C85AFP-2 typically operates at a clock speed of 3 MHz or 5 MHz. It requires a single +5V power supply. It has an addressable memory space of 64 KB. The instruction set includes instructions for data transfer, arithmetic operations, logical operations, and control flow. Programming is typically done in assembly language. The microprocessor requires external memory and I/O devices to function. The CMOS version offered advantages in environments where power consumption was a key concern compared to the original NMOS 8085.
