M41T93規(guī)格書詳情

M41T93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M41T93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 M41T93 is a low power Serial SPI Bus Real Time Clock with a built-in 32.768kHz oscillator (external crystal-controlled for the QFN16 package, and embedded crystal for the SOX18 package). Eight bytes of the Register Map (see Table 3 on page 18) 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

■ Ultra-low battery supply current of 365nA

■ Factory calibrated accuracy ±5PPM guaranteed after 2 reflows (SOX18)

– Much better accuracies achievable using built-in programmable analog and digital calibration circuits

■ 2.0V to 5.5V clock operating voltage

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

■ Automatic switch-over and reset output circuitry (fixed reference)

–M41T93S: VCC= 3.0V to 5.5V (2.85V≤VRST ≤ 3.00V)

–M41T93R: VCC= 2.7V to 5.5V (2.55V≤VRST ≤ 2.70V)

–M41T93Z: VCC= 2.38V to 5.50V (2.25V≤VRST≤2.38V)

■ Compatible with SPI busserial interface (positive clock SPI modes)

■ 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)

■ RESET (RST) output

■ Watchdog timer

■ Programmable 8-bit counter/timer

■ 7 bytes of battery-backed user SRAM

■ Battery low flag

■ Power-down timestamp (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 or an 18-lead embedded crystal SOIC

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