【应用】EPSON内置频率调整32.768kHz晶体单元的时钟IC RX8010SJ用于电话机，可节省设计成本
电话机是通过电信号双向传输话音的终端设备。它的出现，为人们的通讯带来了便利。已经成为了人们生活、工作中必不可少的一个重要组成部分。随着通讯科技的日益发展，移动通信甚至是网络电话相继出现，传统电话机已经不再满足人们对于便捷性、多功能性的要求，逐渐的退出大家生活的应用。但是，在酒店行业以及有些办公行业的应用中，由于总线和分机的管理机制，传统电话机依然是重要的通讯工具。
其产品框图如下：
产品的时间显示需要使用时钟IC。基于产品需求，本文推荐EPSON RX8010SJ。
其优势及特点如下：
1、 内置频率调整32.768kHz晶体单元、内置用户RAM:128位（8位x16，SRAM）、内置完整的日历、闹钟、计时器等功能，可节省客户设计成本，并减少外设的匹配误差
2、 低备用电流：160nA/3V（典型），有效减少电路损耗
3、 标准 IIC 总线接口方式，最高速度 400kHz(4.5V～5.5V)，匹配客户设计、速率满足设计要求
其管脚定义如下：
综上所述，EPSON RX8010SJ具有多种功能内置、低功耗、标准接口、高速率等特点，适用于电话机的应用。
