M41T83規(guī)格書詳情

M41T83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M41T83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 M41T8x are low power Serial I2C Real Time Clocks with a built-in 32.768kHz oscillator (external crystal-controlled for the QFN16 and SO8 packages, embedded crystal for the SOX18 package). Eight bytes of the Register Map (see Table 2 on page 23) are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. An additional 17 bytes of the Register Map provide status/control of the two Alarms, Watchdog, 8-bit Counter, and Square Wave functions. An additional seven bytes are made available as user SRAM.

Features

■ 2.0 to 5.5V clock operating voltage

■ Ultra-low battery supply current of 365nA

■ Counters for tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century

■ Programmable clock calibration (analog and digital)

■ Automatic switchover and reset output circuitry (fixed reference)

– M41T83S

VCC = 3.00V to 5.50V

(2.85V ≤ VRST ≤ 3.00V)

– M41T83R

VCC = 2.70V to 5.50V

(2.55V ≤ VRST ≤ 2.70V)

– M41T83Z

(2.25V ≤ VRST ≤ 2.38V)

■ Serial interface supports I2C Bus (400kHz protocol)

■ Programmable alarm with interrupt function (valid even during battery back-up mode)

■ Optional 2nd programmable alarm available

■ Square wave output defaults to 32KHz on power-up (M41T83 only)

■ RESET (RST) output

■ Watchdog timer

■ Programmable 8-bit counter/timer

■ 7 bytes of battery-backed user SRAM

■ Battery low flag

■ Power-down time stamp (HT bit)

■ Low operating current of 80μA

■ Oscillator stop detection

■ Battery or Super-cap? back-up

■ Operating temperature of –40°C to 85°C

■ Package options include:

– a 16-lead QFN (M41T83),

– an 18-lead embedded crystal SOIC (M41T83), or

– an 8-lead SOIC (M41T82)

■ RoHS compliance: lead-free components are compliant with the RoHS directive.
