General Description
MOTOROLA
1.2 Introduction
The MC68HC05RC16 is a low-cost addition to the M68HC05 Family of
microcontrollers (MCUs) and is suitable for remote control applications.
This device contains the HC05 central processing unit (CPU) core,
including the 14-stage core timer with real-time interrupt (RTI) and
computer operating properly (COP) watchdog systems. On-chip
peripherals include a carrier modulator transmitter. The 16-kbyte
memory map has 15,936 bytes of user 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. This device is available in
28-pin small outline integrated circuit (SOIC), 28-pin dual in-line (DIP),
and 44-pin plastic leaded chip carrier (PLCC) packages. Four additional
I/O lines are available for bond out on the higher pin count package.
