This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is advised that normal precautions should be taken to avoid application of any voltage higher than the maximum rated voltages to this high impedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range VSS(Vin or Vout)VDD. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (e.g. either VSS or VDD).




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 modifications which help eliminate external components in cost sensitive applications.
