GENERAL DESCRIPTION
The MC68HC05SR3 HCMOS microcontroller is a member of the M68HC05 family of low-cost
single-chip microcontrollers. This 8-bit microcontroller unit (MCU) contains on-chip oscillator,
CPU, RAM, ROM, I/O, Timer, and Analog-to-Digital Converter. The MC68HC05SR3 is pin
compatible with the MC6805R3 and is provided as a low power upgrade path for MC6805R3
applications. The low power advantage of CMOS is combined with the addition of I/O and port
modications which help eliminate external components in cost sensitive applications.
The MC68HC705SR3 is an EPROM version of the MC68HC05SR3; it is available in windowed
and OTP packages. All references to the MC68HC05SR3 apply equally to the MC68HC705SR3,
unless otherwise stated.
References specic to the MC68HC705SR3 are italicized in the text and
also, for quick reference, they are summarized in Appendix A.
