Product Summary

The MC68HC11F1CFN4 is a high-performance member of the M68HC11 family of microcontroller units (MCUs). High-speed expanded systems required the development of the MC68HC11F1CFN4 with its extra input/output (I/O) ports, an increase in static RAM (one Kbyte) , internal chip-select functions, and a non-multiplexed bus which reduces the need for external interface logic.
