The MC68HC705SR3 is an EPROM version of the MC68HC05SR3, which 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. The MC68HC705SR3 is available in windowed and OTP packages. All refrences to the MC68HC05SR3 apply equally to the MC68HC705SR3, unless otherwise stated.
