COP8CFE9HLQ9 Application Field and Working Principle

Introduction

COP8CFE9HLQ9, also called 8-bit CMOS flash microcontrollers, is a type of Embedded Microcontrollers developed by national Semiconductor Corporation. It integrates a variety of peripheral circuits and core parts together into a single chip, integrating functions of a peripheral controller, a CPU and a memory chip, and replacing classical computer components such as memory and peripheral expansion cards. Its working voltage range is from 2-5.5V, while the maximum current is only 10mA, which has a great advantage in power-saving.

Application Fields

COP8CFE9HLQ9 is suitable for all kinds of consumer products and industrial control. Its main application fields are as follows:

• Smart home and intelligent household appliances control, including electric mopeds, electric furnaces, air conditioners, rice cookers, TV receivers, toys and robots.
• Industrial process control, such as wind turbines, electric cars, submersibles and elevators.
• Intelligent hand-held devices, such as portable health care products, meter-reading instruments, data entry terminals and PDAs.
• Communication and network terminals, such as PBX, E1, radio repeaters and radio transceivers.

Working Principle

COP8CFE9HLQ9 is a single-chip microcomputer with multiple peripheral elements, including CPU (Central Processing Unit), ROM (Read-Only Memory), RAM (Random Access Memory), Timer, I/O ports and some special internal modules like A/D conversion, PWM and so on. CPU is the core of COP8CFE9HLQ9, responsible for controlling the operation and flow of the whole system, while ROM and RAM are used to store the program and data. According to its application requirements, various peripheral elements can be selected. In controlling of I/O ports to form a complete circuit system, which will complete the designated operating actions.

Conclusion

COP8CFE9HLQ9 is a family of Embedded Microcontrollers developed by National Semiconductor Corporation. Its working voltage range is from 2-5.5V, while its maximum current is only 10mA, which has great advantages in power-saving. Its main fields of application include smart home, industrial process control, intelligent hand-held devices and communication and network terminals. The working principle of COP8CFE9HLQ9 is to select the peripheral elements required by the application into the chip, control the I/O ports to form a complete circuit system, and complete the designated operating actions.
