Appendix A
MC68HC705L16
A.1 Introduction
The MC68HC705L16 is similar to the MC68HC05L16 with the exception of the EPROM feature. The
program ROM on the MC68HC05L16 has been replaced by 16-K electrically programmable read-only
memory to allow modification of the program code for emulation. The entire data sheet of the
MC68HC05L16 applies to the EPROM part with the additions and exceptions explained in this appendix.
The additional features available on the MC68HC705L16 are:
16,384 bytes of EPROM
On-chip bootstrap firmware for programming use
Self-check mode replaced by bootstrap capability
A.2 Differences between MC68HC05L16 and MC68HC705L16
A.3 MCU Structure
Figure A-1 shows the structure of the MC68HC705L16 MCU.
A.4 Mask Options
There are no mask options available for the MC68HC705L16. For this reason, the address option map
shown in Chapter 2 Memory Map has no meaning.
