飞象网讯(魏德龄/文)上周,德州仪器在北京发布了MSP430FR2355微控制器,产品将最大工作温度提升到了105°C,配合铁电存储器、主频的提升及可智能模拟组合配置等升级,在保持超值价格、超可靠性的情况下,让德州仪器微控制器能灵活满足更多领域的应用需求。

 

105°C的背后,满足工业自动化要求

目前,国内自动化工厂中对于微控制器有着不小的需求,流量测量、温度感应、液位测量、位置感应等均需要微控制器在其中发挥作用。在以往的产品中,微控制器最高的支持温度为85°C,新型MSP430FR2355微控制器将工作温度范围扩展至-40至105°C。随着工作温度的提升,也让MSP430FR2355可以满足更多工业自动化场景。

据德州仪器超低功耗MSP微控制器事业部总经理Miller Adair介绍:“德州仪器为了能提高产品的支持温度,做了大量的模拟,确保在不降低可靠性的前提下,对整个系统进行改造。”他还表示未来大量产品都将会支持到105°C。

铁电存储器(FRAM)在新产品中也得到了应用,最高32KB FRAM,具有超低耗能,同时又具备高可靠性,确保可写入一千万亿次以上,同时也让MSP430FR2355具备了更好的灵活性。为了满足工厂自动化的需求,MSP430FR2355还将主频从16MHz提升到了24MHz,以便应对工厂环境下需要持续进行监控时的运算要求。

 

面对不同领域,可智能模拟组合配置

MSP430FR2355微控制器的另一大特点在于拥有可配置的模拟集成单元,其中拥有四个灵活智能模拟组合模块,分别为ADC、DAC、OPAMP、COMP,每个组合模块都可根据客户需求进行配置,最终可让微控制器面向多种领域提供支持。客户在使用中,只需要在任意配置中使用其中三个或全部四个模块,就能满足应用需求。

例如在上图中,如果客户的需求为烟雾探测器,只需要利用智能模拟组合进行配置,就能让MSP430FR2355完成变身,无需单独设计。同理,在烟雾探测器中也能直接通过智能模拟组合来完成。相当于一颗MSP430FR2355就能模拟出各种领域中所需要的电路。

据悉,MSP430铁电存储器系列产品可应用于楼宇自动化、电网基础设置、自动化工厂及日常消费品四大领域。从可视门铃、摄像头、烟雾探测器,再到水表、燃气表、热量表,还有温度传感器、PLC IO模块,最后再到耳机、冰箱、微波炉。从工业到生活,MSP430系列微控制器产品都能满足需求。

另外,MSP430FR新增超值系列及可扩展性,仅25美分的价格就能获得25项具有代码示例的功能,让价格适用于成本敏感性应用,工程师还可以从MSP430FR2355 MCUs中选择更为合适的内存与处理速度。
