全球领先的高性能频率管理组件和天线产品Raltron发布了RTT21064系列实时时钟，旨在在提供各种功能和降低功耗的同时，在准确跟踪当前时间方面发挥关键作用。RTC模块专门为公用事业计量、服务器、汽车、工厂自动化和可再生能源设计，是一种I2C总线接口实时时钟，具有低功耗和数字偏移功能。石英晶振RTT21064具有-40℃~+85℃的宽工作温度范围，在较高的温度下功耗保持不变。这最大限度地减少了时钟漂移，使其能够很好地适应要求苛刻的户外应用和更高温度的服务器外壳环境。
Raltron的RTC模块支持备用电池寿命，嵌入式32.768kHz TCXO作为一体式设备，与分立组件相比提供最佳性能，简化新产品开发中的集成，并加快上市时间。它具有日历（年、闰年自动更正、月、日、小时、分钟、秒）、时钟、时间戳、可调整周期的计时器输出和报警功能。除了负责系统及其时钟的定时功能外，RTT21064模块还确保系统中发生的所有进程都适当同步
RTT21064有一个紧凑的3.2mmx2.5mmx1.0mm封装贴片晶振，具有1.0uA的低电流消耗和在+25°C（典型）下最大频率精度提高到5+/-23ppm的特点，使其也适用于便携式和小型电子设备。
Raltron总裁Sasha Wolloch表示：“我们开发RTT21064是为了满足在长时间和宽温度范围内需要稳定性、准确性和一致性的苛刻应用。如果你注意到系统时钟持续滞后，那可能是因为RTC在某些温度范围内无法运行。”。“在公用事业计量方面，时间戳必须准确，尤其是考虑到今天发生的电力中断次数。RTT21064非常适合这一点。”

Raltron实时时钟模块RTT21064具有低功耗和数字偏移功能
Raltron, a global leader in high performance frequency management components and antenna products, has released the RTT21064 Series of Real Time Clocks designed to play a critical role in keeping accurate track of current time while providing a variety of functions and reducing power consumption. Designed specifically for Utility Metering, Servers, Automotive, Factory Automation and Renewable Energy, the RTC module is an I2C bus interface real-time clock with low power consumption and digital offset function. With a wide operating temperature range of -40℃ ~ +85℃, power consumption for the RTT21064 remains constant at higher temperatures. This minimizes clock drift positioning it well for demanding outdoor applications and higher temperature server enclosure environments.
Raltron’s RTC module supports backup battery life with an embedded 32.768kHz TCXO serving as an allin-one device to provide optimum performance compared to discrete components, simplify integration in new product developments, and accelerate time to market. It features calendar (year, leap-year autocorrection, month, day, hour, minute, second), clock, time stamp, timer output with adjustable periods, and alarm functions. In addition to being responsible for the timing function of the system and its clock, the RTT21064 module ensures that all processes occurring in the system are appropriately synchronized.
Available in a compact 3.2mm x 2.5mm x 1.0mm package, the RTT21064 features low current consumption of 1.0uA, and improved frequency accuracy of 5+/-23ppm max @ +25°C (TYP.) making it also suitable for portable and small size electronic devices.
“We developed the RTT21064 for demanding applications that need stability, accuracy and consistency over a long period of time and over a wide range of temperatures. If you have ever noticed a system clock continually running behind, that’s probably due to an RTC that is not performing across certain temperature ranges” said Sasha Wolloch, President of Raltron. “When it comes to utility metering, time stamps must be accurate, especially with the number of power interruptions occurring today. The RTT21064 is perfect for this.”
