描述 Description

Overview The MC68HC05L5 is an 80-pin microcontroller unit (MCU) with highly sophisticated on-chip peripheral functions. The memory map includes 8 Kbytes of user ROM and 256 bytes of static RAM. The MCU has five parallel ports: A, B, C, D, and E. The MC68HC05L5 includes a timebase circuit, 8- and 16-bit timers, a computer operating properly (COP) watchdog timer, liquid crystal display (LCD) drivers, and a simple serial peripheral interface (SSPI).
