【应用】EPSON RTC模块RX8111CE满足胰岛素泵严苛要求，芯片和晶体合封，功耗低且稳定可靠
实时时钟简称RTC，可以应用于许多产品中，如电脑、手机、平板、电视、音响等电子产品，甚至是航空航天，例如飞机仪表盘、航天器导航系统等也都会用到RTC。简单来说就是任何需要记录和显示时间、同步设备操作时间的产品都有可能使用RTC。在客户设计的一款家用胰岛素泵中就需要用到RTC实现定时的功能，到了设定的时间间隔便会注射一定的胰岛素。

图二 家用胰岛素泵系统框图
由于是胰岛素泵是三类医用产品，一旦发送意外可能导致严重的后果，因此在设计选型时对电子器件要求比较严苛。对精度和稳定性都有很高的要求，通常情况下是选用久经市场考验的大品牌产品。客户在选型RTC时得到了我司的帮助，成功应用了EPSON的RTC模块。
图三 RX8111CE大致参数
我司技术人员经过和客户的沟通了解到客户目前的述求，推荐了EPSON的RX8111CE系列型号，该产品主要有以下几个亮点：
1. EPSON是国际大品牌，晶振设计和生产工艺行业顶尖，产品稳定可靠；
2. 芯片和晶体合封，整体价格更有优势，可帮助客户节约成本；
3. 整体体积3.2*2.5*1mm，助力便携的胰岛素泵应用；
4. 功耗低，3V供电时消耗100nA，适合电池供电的胰岛素泵；
