MC68HC11ED0MFN3中文资料飞思卡尔数据手册PDF规格书

Introduction

The MC68HC11ED0 is a low-cost member of the M68HC11 Family of microcontrollers (MCU). This MCU has a multiplexed address/data bus and is characterized by high speed and low-power consumption. The fully static design allows operation at frequencies from 3 MHz to dc.

Pin count is minimized for cost-sensitive applications. Because there is no on-chip read-only memory (ROM), this device is optimized for expanded-bus systems. On-chip serial peripheral interface (SPI) and serial communications interface (SCI) provide a convenient means or transferring data to and from internal random-access memory (RAM).
