General Description

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.
