描述

根據名稱,很容易知道 Grove - 高精度 RTC 與常規時鐘芯片 DS1307 的 Grove - RTC 相比是更準確的實時時鐘。 Grove 的核心 - 高精度 RTC 是 PHILIPS PCF85063TP,它是一款針對低功耗進行優化的 CMOS 芯片,在特定環境下典型電流可低於 1.2uA。所有地址和數據通過雙線雙向 I2C 總線串行傳輸,最高速度為 400kbit / s。偏移寄存器允許微調時鐘,寄存器地址在每次讀取或寫入數據字節後自動遞增。

Grove - 高精度 RTC 可能是迄今為止您可以獲得的最精確和低功耗的 RTC,如果您的應用需要高精度時序提供,請不要猶豫,獲得一個。

Description

According to the name, it is easy to know that the Grove – High Precision RTC is a more accurate real-time-clock comparing to Grove – RTC with the regular clock chip DS1307. The heart of Grove – High Precision RTC is PHILIPS PCF85063TP, which is a CMOS chip that optimized for low power consumption, the typical current can be less than 1.2uA at certain environment. All addresses and data are transferred serially via the two-line bidirectional I2C bus, of which the maximum speed is 400kbit/s. An offset register allows fine-tuning of the clock, and the register address is incremented automatically after each read or written data byte.

The Grove – High Precision RTC might one the most precise and low consumption RTC you can get so far, If your application requires high precision timing providing, please don’t hesitate to get one.
