General Description

The 68HC11F1 is a high-performance member of the 68HC11 family of microcontroller units (MCUs). High-speed expanded systems required the development of this chip 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. The timer, serial I/O, and analog-to-digital (A/ D) converter enable functions similar to those found in the 68HC11E9.
