  方案描述:

  Renesas' range of low power 8/16-bit microcontrollers offers the optimized functions including A/D converter for measuring water temperature, serial communication interfaces, and LCD controller for displaying data. A heat meter is essential for managing the heat level and billing data of a heating system. In addition to basic functions for sensing water temperature, flow, and measuring heat units, a variety of other functions are also in demand for heat meters. The high-demand functions include display of spot temperature, flow rate, and wired or wireless connection with a central control unit. 热量表,是计算热量的仪表。热量表的工作原理:将一对温度传感器分别安装在通过载热流体的上行管和下行管上,流量计安装在流体入口或回流管上(流量计安装的位置不同,最终的测量结果也不同),流量计发出与流量成正比的脉冲信号,一对温度传感器给出表示温度高低的模拟信号,而积算仪采集来自流量和温度传感器的信号,利用积算公式算出热交换系统获得的热量。

  1.Overview

  These MCUs are fabricated using a high-performance silicon gate CMOS process, embedding the R8C/Tiny SeriesCPU core, and are packaged in a 32-pin molded-plastic LQFP. It implements sophisticated instructions for a high levelof instruction efficiency. With 1 Mbyte of address space, they are capable of executing instructions at high speed.Furthermore, the R8C/27 Group has on-chip data flash (1 KB × 2 blocks).

  The difference between the R8C/26 Group and R8C/27 Group is only the presence or absence of data flash.Their peripheral functions are the same.

  1.1Applications

  Electronic household appliances, office equipment, audio equipment, consumer products, automotive, etc.
