GENERAL DESCRIPTION
The MC68HC05SU3A 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, and Timer. The MC68HC05SU3A is pin compatible with the MC6805U3
and is provided as a low power upgrade path for MC6805U3 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.
