General Description

1.1 Introduction

The MC68HC908AS60A, MC68HC908AZ60A, and MC68HC908AZ60E are members of the low-cost,

high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the

enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory

sizes and types, and package types.

These parts are designed to emulate the MC68HC08ASxx and MC68HC08AZxx automotive families and

may offer extra features which are not available on those devices. It is the user’s responsibility to ensure

compatibility between the features used on the MC68HC908AS60A, MC68HC908AZ60A, and

MC68HC908AZ60E and those which are available on the device which will ultimately be used in the

application.

For detailed information regarding the MC68HC908AZ60E refer to Appendix B MC68HC908AZ60E.
