Product Summary
The 68HC705J2CP 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 68HC705J2CP is an expansion of the MC68HC05J1 design. On-chip memory is enhanced with 2 Kbytes of erasable, programmable ROM (EPROM), 112 Kbytes of RAM, and a bootloader ROM.
