GENERAL DESCRIPTION
The MC68HC05L1 HCMOS microcontroller is a member of the M68HC05 Family of low-cost
single-chip microcontrollers. This 8-bit microcontroller unit (MCU) contains an on-chip oscillator,
CPU, RAM, ROM, parallel I/O capability with pins programmable as input or output, one 16-bits
programmable timer, liquid crystal display driver circuitry and 6-channel A/D converter.
The MC68HC705L1 is an EPROM version of the MC68HC05L1; it is available in windowed and
OTP 56-pin SDIP and 64-pin QFP packages. All references to the MC68HC05L1 apply equally to
the MC68HC705L1, unless otherwise stated.
References specic to the MC68HC705L1 are
italicized in the text, and also, for quick reference, they are summarized in Appendix A.
