The MC68HC705J2 is a member of the low-cost, high-performance M68HC05
Family of 8-bit microcontroller units (MCUs). The high-density, complementary
metal-oxide semiconductor (HCMOS) M68HC05 Family is based on the
customer-specified integrated circuit (CSIC) design strategy. All MCUs in the
family use the popular M68HC05 central processor unit (CPU) and are
available with a variety of subsystems, memory sizes and types, and package
types.
The MC68HC705J2 is an expansion of the MC68HC05J1 design.
memory is enhanced with 2 Kbytes of erasable, programmable ROM (EPROM),
112 Kbytes of RAM, and a bootloader ROM.
The MCU features include the following:
