Features & Applications
The M41T93RQA6F is a 5.5 V supply voltage, low power serial SPI Bus Real-Time Clock with a built-in 32.768 KHz oscillator, available in surface mount QFN-16 package.
This device has a built-in power sense circuit which detects power failures and automatically switches to the battery supply when a power failure occurs. The energy needed to sustain the clock operations can be supplied by a small lithium button battery when a power failure occurs.
Features:
- Ultra-low battery supply current of 365 nA
- Factory calibrated accuracy ±5 ppm guaranteed after 2 reflows (SOX18)
- Much better accuracies achievable using built-in programmable analog and digital calibration circuits
- 2.0 V to 5.5 V clock operating voltage
- Counters for tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century
- Automatic switchover and reset output circuitry (fixed reference)
- M41T93R: VCC = 2.7 V to 5.5 V (2.55 V ≤ VRST ≤ 2.70 V)
- Compatible with SPI bus serial interface (supports SPI mode 0 [CPOL = 0, CPHA = 0])
- Programmable alarm with interrupt function (valid even during battery backup mode)
- Optional 2nd programmable alarm available
- Square wave output (defaults to 32 KHz on power-up) RESET (RST) output
- Watchdog timer
- Programmable 8-bit counter/timer
- 7 bytes of battery-backed user SRAM
- Battery low flag
- Low operating current of 80 μA
- Oscillator stop detection
- Battery or SuperCap™ backup
- 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
