M41T00CAP集成電路（IC）的實時時鐘規(guī)格書PDF中文資料

M41T00CAP屬于集成電路（IC）的實時時鐘。由意法半導體集團制造生產(chǎn)的M41T00CAP實時時鐘實時時鐘 (RTC) 為幾乎所有需要保持精確時間的電子設備提供時間和/或日期信息。時鐘類型有二進制計數(shù)器、時鐘/日歷/監(jiān)控器、歷時計時器、幻時鐘芯片、便攜式系統(tǒng)控制器、溫度記錄器、時間事件記錄器和計時器時鐘外設。其包含 2 B 至 2 MB 不等的存儲器，接口選項有 I2C、并行、串行、SPI、1 線式、2 線式、3 線式和 4 線式。

Description

The M41T00CAP is a low-power serial real-time clock (RTC) with integral battery and crystal in ST’s 24-pin CAPHAT? package. It includes a crystal controlled, 32.768 kHz oscillator and has a built-in power sense circuit which detects power failures and automatically switches to the backup battery when a power failure occurs.

Features

■ Real-time clock (RTC) with backup battery integrated into package

■ Uses M41T00S enhanced RTC with precision switchover reference

■ 400 kHz I2C serial interface

■ Automatic switchover and deselect circuitry with fixed reference voltage

– VCC = 2.7 to 5.5 V operating voltage range

– 2.6 V (typ) power-fail deselect (switchover) threshold

■ Counters for seconds, minutes, hours, day, date, month, year and century

■ Software clock calibration

■ Low operating current of 300 μA

■ Oscillator stop detection

■ Battery backup

■ Operating temperature of 0 to 70 °C

■ Self-contained battery and crystal in CAPHAT? DIP package

■ RoHS compliant

– Lead-free second level interconnect
