MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC68HC11FTS/D MC68HC11F1 MC68HC11FC0 Technical Summary 8-Bit Microcontroller 1 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). 1.1 Features MC68HC11 CPU 512 Bytes of On-Chip Electrically Erasable Programmable ROM (EEPROM) with Block Protect (MC68HC11F1 only) 1024 Bytes of On-Chip RAM (All Saved During Standby) Enhanced 16-Bit Timer System — 3 Input Capture (IC) Functions — 4 Output Compare (OC) Functions — 4th IC or 5th OC (Software Selectable) On-Board Chip-Selects with Clock Stretchin...
