GENERAL DESCRIPTION
The MC68HC05SR3 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, Timer, and Analog-to-Digital Converter. The MC68HC05SR3 is pin compatible with the MC6805R3 and is provided as a low power upgrade path for MC6805R3 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.
