Plentiful system level peripheral functions, such as I/OPort, Timer, UART, SPI, I2C, PWM, ADC, Watchdog Timer, Analog Comparator and Brown-outDetector, have been incorporated into the NM1817 series in order to reduce component count,board space and system cost. These useful functions make the NM1817 series powerful for a widerange of motor driver applications.The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high sideconfiguration which operates up to 600 volts. It’s also built-in the temperature sense output signalfor MCU detection & one comparator for over current protectionAdditionally, the NM1817 is equipped with ISP (In-System Programming) and ICP (In-CircuitProgramming) functions, which allow the user to update the program memory without removing thechip from the actual end product.NM1817 is the combination of NM1120 and NPT23011 Gate Driver. User may refer to the TRM ofNM1120 and the datasheet of NPT23011 for the detailed specification. The NM1120 BSP is alsofor NM1817 software developing.NM1120NPT23011NM1817NM1817 SERIES DATASHEETNM1817 SERIES DATASHEET2 FEATURES● Gate Driver⏹ Programmable enable/disable gate driver by MCU I/O of

低成本多功能电力载波通讯模块

低成本多功能电力载波通讯模块产品说明书● 一体化设计、超小体积● 免外围调试、使用简单● 嵌入式模块、即插即用● 多功能集成、应用广泛模块简介：PLM系列低成本多功能电力载波通讯模块是电力线载波集抄技术的一个普及应用，通过对载波集抄技术的优化更新，保留其简单实用的功能，使模块成本大幅度下降，从而使组建低成本的电力线网络控制系统成为现实。

电力载波通讯专用芯片是实现数据在电力线上传输的关键部分，数据在电力线上的调制和解调就由该部分完成，以往必须采用国外昂贵的电力线载波专用IC来实现这一功能，成本居高不下，这也限制了它的普及和应用。

这几年来我们通过不断的探索和改进，利用独特的载波技术，终于成功完成了这一系列应用非常简单的低成本多功能电力载波通讯模块。

PLM系列电力载波通讯模块提供半双工通信功能，可以在220V，50Hz 电力线上可以实现局域通信功能。

在同一台变压器下，多个模块可以连接在同一条电力线上，在主从通信模式下，模块分别单独工作，不会相互影响。

载波通讯模块由内部的单片机进行数据的传送和接收，通过修改单片机内部的通讯协议，即可进行双向数据的透明传输，组成一个通讯系统；此外还可以通过修改内部单片机的软件，实现不同的模块功能。

基于电力线的复杂环境，为了确保通讯的成功率，模块采用了较低的通讯速率，适用于通讯速度要求不高的场合，例如：● 宾馆、酒店、商场、小区灯光的集中控制和管理● 无人值班的电气设备的远程控制和管理● 工厂、矿井的电气设备的远程控制和监控● 远程温度、湿度的测量和监控● 远程抄表系统● 简单的基于电力线的内部呼叫系统● 智能家居的各种应用● 替代各种有线方式的数据传输，节省成本以上各种应用可以根据用户需求，进行内部单片机不同功能软件的固化，形成嵌入式模块，方便批量生产，降低产品成本和保护生产商的技术优势。

应用框图：模块应用介绍：为了使用户能够更简单地使用载波模块，我们采用了高度集成的电路设计，整个模块取消了外围电力线耦合电路和调整电路，具体应用时简单到只需接入外部供电电源即可，数据的发送和接收也只需遵循常用的单片机串口协议进行操作即可。

模块外形尺寸为70mm（长）×50mm（宽）×22.7mm（高），模块正视、侧视、底视示意图参见图1、图2。

强电和弱电的整体位置如图2所示，强电在左下角，弱电在右上角。

单相载波模块的结构框图如下：

图2 模块底视示意图
模块上的两个指示灯为高亮、长寿命LED指示灯，RXD指示灯为绿色，TXD为红色。

载波通信模块指示灯说明：
TXD灯—红灯闪烁时，表示模块向电网发送数据；
RXD灯—绿灯闪烁时，表示模块从电网接收数据。

5.弱电接口定义
模块弱电接口采用2×6双排插针作为连接件，电能表弱电接口采用2×6双排插座作为连接件。

ART通信速率
SSC1641通信速率自适应，可以实现1200bps、2400bps、4800bps和9600bps四种通信速率。

7.2.字节格式
每字节含8位二进制码，传输时加上一个起始位（0）、一个偶校验位和一个停止位(1)共11位。

其传输序列如图5所示，D0是字节的最低有效位，D7是字节的最高有效位。

先传低位，后传高位。
