Product Overview
MAX31331TETB+ is an ultra-low power, real-time clock (RTC). It is a time-keeping device that consumes a nominal 65nA time-keeping current, extending battery life. It supports a wide range of 32.768KHz crystals. A crystal with any capacitive loading (CL) spec can be used, which broadens the pool of usable crystals for this device. This device is accessed through an I²C serial interface. This device also features a backup supply pin (VBAT) and automatically switches over to the backup supply (VBAT) when the main supply (VCC) drops below the programmed threshold voltage and the backup supply (VBAT) voltage. Other features include two time-of-day alarms, interrupt outputs, programmable square-wave output, event detection input with timestamping, and a serial bus timeout mechanism. It is used in applications such as medical, wearables, portable Instruments, telematics, industrial, IoT.
- Automatic switchover to backup supply on power fail event
- Trickle charger for external supercapacitor or rechargeable battery
- 1.1V to 5.5V timekeeping voltage range, 32-byte user RAM
- 1.62V to 5.5V interface voltage range, 1/128 second register
- Event detection with dedicated pin, timestamps for various events
- Low battery voltage detection, alarms and countdown timer
- Timekeeping current is 65nA typical at (VCC = +1.1V, TA = +25°C)
- I/O capacitance is 10pF typical at (VCC = +1.1V to +5.5V, TA = -40°C to +85°C)
- SCL clock frequency is 400KHz maximum at (VCC = +1.1V to +5.5V, TA = -40°C to +85°C)
- Operating temperature range from -40°C to +85°C, 10-TDFN package
