MC68HC05RC9数据手册恩XP中文资料规格书

描述 Description

Overview The MC68HC05RC9 is a general-purpose, low-cost addition to the M68HC05 Family of microcontroller units (MCUs) and is suitable for remote control applications. It 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. The MC68HC05RC9 is available in a 28-pin small outline integrated circuit (SOIC) package, a 29-pin dual-in-line package (DIP), or a 44-pin plastic leaded chip carrier (PLCC). Four additional I/O lines are available for bond out in higher pin count packages.
