The MC68HC705RC16 is a low-cost addition to the M68HC05 Family of microcontrollers (MCUs) and is suitable for remote control applications.It contains the HC05 CPU core, including the 14-stage core timer with RTI and COP watchdog systems. On-chip peripherals include a carrier modulator transmitter. The 16-Kbyte memory map has 15,936 bytes of user EPROM, 340 bytes of boot ROM, and 352 bytes of RAM. There are 20 input/output (I/O) lines (eight having keyscan pullups/interrupts) and a low-power reset pin.

The MC68HC705RC16 is available in 28-pin small outline integrated circuit (SOIC), dual in-line (DIP), or plastic leaded chip carrier (PLCC) packages. Four additional I/O lines are available for bond out in the 44-lead PLCC package.
