MC68HC05SR3 is a member of Our M68HC05 family of cost-effective single-chip microcontrollers. This 8-bit microcontroller unit (MCU) contains on-chip oscillator, CPU, RAM, ROM, I/O, timer, and analog-to-digital converter (ADC). 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 that help eliminate external components in cost-sensitive applications. The MC68HC705SR3 is available in windowed and OTP packages. All references to the MC68HC05SR3 apply equally to the MC68HC705SR3, unless otherwise stated.
