GENERAL DESCRIPTION
The MC68HC05F8 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, I/O, timer, serial peripheral interface, Manchester encoder/decoder,
DTMF/melody generator, and COP watchdog monitor. This MCU is particularly suitable for
cordless telephones with an answering machine.
The MC68HC705F8 is an EPROM version of the MC68HC05F8. All references to the
MC68HC05F8 apply equally to the MC68HC705F8, unless otherwise stated. References specific
to the MC68HC705F8 are italicized in the text.
