HCMOS Single-Chip Microcontroller

Motorola => Freescale 

1 INTRODUCTION

The HCMOS MC68HC11A8 is an advanced 8-bit microcontroller (MCU) with highly

sophisticated on-chip peripheral capabilities. A fully static design and high-density

complementary metal-oxide semiconductor (HCMOS) fabrication process allow E-se-

ries devices to operate at frequencies from 3 MHz to dc, with very low power consump-

tion.

1.2 General Description

The high-density CMOS technology (HCMOS) used on the MC68HC11A8 combines

smaller size and higher speeds with the low power and high noise immunity of CMOS.

On-chip memory systems include 8 Kbytes of ROM, 512 bytes of electrically erasable

programmable ROM (EEPROM), and 256 bytes of static RAM.

A block diagram of the MC68HC11A8 is shown in Figure 1-1. Major peripheral func-

tions are provided on-chip. An eight channel analog-to-digital (A/D) converter is includ-

ed with eight bits of resolution. An asynchronous serial communications interface
