Description

MC6809CP-G Rochester Electronics 1 Core, 8-Bit Microprocessor 8MHz 5V Through Hole 40DIP (0.600″, 15.24mm)

The MC6809CP-G is a powerful 8-bit microprocessor from the Motorola 6800 family, widely known for its advanced architecture and features that were ahead of its time. The MC6809 is used in various embedded systems, industrial controls, and consumer electronics applications where efficient data processing and advanced instruction handling are required.

The MC6809CP-G is an 8-bit microprocessor, but unlike its predecessors, it includes several 16-bit features, such as 16-bit registers, 16-bit arithmetic, and a highly efficient instruction set. It supports multiple addressing modes and offers a variety of instructions for data manipulation, control, and arithmetic operations. The microprocessor is often favored for its relatively high speed and flexible interrupt handling capabilities.
