全球領(lǐng)先的高性能頻率管理組件和天線產(chǎn)品Raltron發(fā)布了RTT21064系列實時時鐘，旨在在提供各種功能和降低功耗的同時，在準(zhǔn)確跟蹤當(dāng)前時間方面發(fā)揮關(guān)鍵作用。RTC模塊專門為公用事業(yè)計量、服務(wù)器、汽車、工廠自動化和可再生能源設(shè)計，是一種I2C總線接口實時時鐘，具有低功耗和數(shù)字偏移功能。石英晶振RTT21064具有-40℃~+85℃的寬工作溫度范圍，在較高的溫度下功耗保持不變。這最大限度地減少了時鐘漂移，使其能夠很好地適應(yīng)要求苛刻的戶外應(yīng)用和更高溫度的服務(wù)器外殼環(huán)境。
Raltron的RTC模塊支持備用電池壽命，嵌入式32.768kHz TCXO作為一體式設(shè)備，與分立組件相比提供最佳性能，簡化新產(chǎn)品開發(fā)中的集成，并加快上市時間。它具有日歷（年、閏年自動更正、月、日、小時、分鐘、秒）、時鐘、時間戳、可調(diào)整周期的計時器輸出和報警功能。除了負(fù)責(zé)系統(tǒng)及其時鐘的定時功能外，RTT21064模塊還確保系統(tǒng)中發(fā)生的所有進程都適當(dāng)同步
RTT21064有一個緊湊的3.2mmx2.5mmx1.0mm封裝貼片晶振，具有1.0uA的低電流消耗和在+25°C（典型）下最大頻率精度提高到5+/-23ppm的特點，使其也適用于便攜式和小型電子設(shè)備。
Raltron總裁Sasha Wolloch表示：“我們開發(fā)RTT21064是為了滿足在長時間和寬溫度范圍內(nèi)需要穩(wěn)定性、準(zhǔn)確性和一致性的苛刻應(yīng)用。如果你注意到系統(tǒng)時鐘持續(xù)滯后，那可能是因為RTC在某些溫度范圍內(nèi)無法運行。”。“在公用事業(yè)計量方面，時間戳必須準(zhǔn)確，尤其是考慮到今天發(fā)生的電力中斷次數(shù)。RTT21064非常適合這一點。”

Raltron實時時鐘模塊RTT21064具有低功耗和數(shù)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.”
