M41T81M6F規(guī)格書詳情
M41T81M6F屬于集成電路(IC)的實(shí)時(shí)時(shí)鐘。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的M41T81M6F實(shí)時(shí)時(shí)鐘實(shí)時(shí)時(shí)鐘 (RTC) 為幾乎所有需要保持精確時(shí)間的電子設(shè)備提供時(shí)間和/或日期信息。時(shí)鐘類型有二進(jìn)制計(jì)數(shù)器、時(shí)鐘/日歷/監(jiān)控器、歷時(shí)計(jì)時(shí)器、幻時(shí)鐘芯片、便攜式系統(tǒng)控制器、溫度記錄器、時(shí)間事件記錄器和計(jì)時(shí)器時(shí)鐘外設(shè)。其包含 2 B 至 2 MB 不等的存儲(chǔ)器,接口選項(xiàng)有 I2C、并行、串行、SPI、1 線式、2 線式、3 線式和 4 線式。
Description
The M41T81 is a low-power serial RTC with a built-in 32.768 kHz oscillator (external crystal controlled).
Features
■ For all new designs other than automotive, use
M41T81S (contact the ST sales office for
automotive grade)
■ Counters for tenths/hundredths of seconds,
seconds, minutes, hours, day, date, month,
year, and century
■ 32 KHz crystal oscillator integrating load
capacitance (12.5 pF) providing exceptional
oscillator stability and high crystal series
resistance operation
■ Serial interface supports I2C bus (400 kHz
protocol)
■ Ultra-low battery supply current of 0.6 μA
(typ at 3 V)
■ 2.0 to 5.5 V clock operating voltage
■ Automatic switch-over and deselect circuitry
(for 3 V application select M41T81S datasheet)
■ Power-down time stamp (HT bit) allowing
determination of time elapsed in battery
backup
■ Programmable alarm and interrupt function
(valid even during battery backup mode)
■ Accurate programmable watchdog timer (from
62.5 ms to 128 s)
■ Software clock calibration to compensate
crystal deviation due to temperature
■ Operating temperature of –40 to 85 °C
■ ECOPACK? package available
