S-35390A是可以在超低消耗电流、宽工作电压范围内工作的2线CMOS实时时钟IC。工作电 压为1.3 ~ 5.5 V、可适用于从主电源电压到备用电池电压的宽幅电源电压。通过0.25 μA的计 时消耗电流和宽范围的计时电源电压，可大幅度地改善电池的持续时间。在使用备用电池工 作的系统中，内置的自由寄存器可作为用户备用存储器来使用。在主电源切断前存储在寄存 器中的信息，可在电压恢复后的任何时候读出。 本产品因为内置了时钟校正功能，所以可以在很宽的范围内校正因振荡电路的频率偏差所导 致的时钟数据的提前或滞后。通过此功能和温度传感器的结合，可根据温度变化来对时钟进 行校正，从而实现不受环境温度影响的高精度的计时功能-err

本系统是一个设计较完善的家用全数字功率放大器。它采用了美国APOGEE公司最新的DDX直接数字放大技术，音质直逼高档模拟放大器，同时，为了扩大使用范围，系统进一步集成了模拟音频输入通道，便于没有数字音频信号的用户使用该系统。操作方面采用了大型的128*64点阵液晶显示模块和非常方便易用的旋转编码器，同时更具有遥控功能。软件方面，以Atmega16单片机核心，采用了全中文菜单显示，由旋转编码器和遥控器作为输入设备，旋转编码器和遥控器均可实现全功能的操作。-This system is a better designed home all-digital power amplifier. It uses the U.S. APOGEE" s latest DDX Direct Digital Amplification technology, sound quality almost equal to high-end analog amplifiers at the same time, in order to expand the scope of application, the system further integrates the analog audio input channels, there is no digital audio signals to facilitate users of the system. Operational use of a large 128* 64 dot matrix LCD display module and very easy to use rotary encoder, but also has a remote control function. Software, in order to Atmega16 microcontroller core, which features a full Chinese menu display by the rotary encoder and remote control as input device, rotary encoders and remote controls can achieve a fully functional operati
