$Features & Applications
The M41T93RMY6F is a part of M41T series I2C RTC. It has an operating temperature ranging from -40 °C to +85 °C and it comes in SOIC-18 Packaging.
The M41T93 is a low-power serial SPI bus real-time clock with a built-in 32.768 kHz oscillator (external crystal-controlled for the QFN16 package, and embedded crystal for the SOX18 package). Eight bytes of the register map 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 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 back-up mode)
- Optional 2ndprogrammable 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
- Power-down time stamp (HT bit)
- 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
