Introduction

The MC68HC11F1 is a high-performance member of the M68HC11 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 MC68HC11E9.

The MC68HC11FC0 is a low cost, high-speed derivative of the MC68HC11F1. It does not have

EEPROM or an analog-to-digital converter. The MC68HC11FC0 can operate at bus speeds as high as

six MHz.

This document provides a brief overview of the structure, features, control registers, packaging information and availability of the MC68HC11F1 and MC68HC11FC0. For detailed information on

M68HC11 subsystems, programming and the instruction set, refer to the M68HC11 Reference Manual

(M68HC11RM/AD).
