基于I^2C总线的智能温度控制器

The Intelligent Temperature Controller Based on PC Bus

目前,温度控制器正向单片集成化、智能化的方向迅速发展。TCN75是美国Telcom公司生产的带I^4总线串行接口的智能温度控制器。它可广泛用于数字温度计、温控仪、电信设备、UPS电源、复印机等办公设备和家用电子产品领域。文中介绍了TCN75型智能温度控制器的性能特点、工作原理及通信方式,并阐述其与单片机的接口电路。

At present,the temperature controller developx rapidly into single-chip integration and intelligence. TCN75 is an intelligent temperature controller with I2C Bus interface, which is produced by Telcom Corporation > USA. It can be widely used in office devices and home electronic products, such as digital thermometer,temperature-control instrument,telecom devices,UPS power,copycat and so on. In this paper,the performance characteristics and operation principles of TCN75 intelligent temperature controller based on I2C bus are introduced,and its circuit with MCU is discussed.
