MAX31342 - Real-Time Clock

General Description

The MAX31342 low-current, real-time clock (RTC) is a time-keeping device that provides an extremely low timekeeping current, permitting longer life from a power supply.

The MAX31342 supports 6pF high-ESR crystals, which broaden the pool of usable crystals for the devices.

Key Features

  • include two time-of-day alarms, interrupt outputs, a programmable square-wave output, and a serial bus timeout mechanism. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in 24-hour mode. The MAX3.

MAX31342 Low-Current, Real-Time Clock with I2C Interface General Description The MAX31342 low-current, real-time clock (RTC) is a time-keeping device that provides an extremely low timekeeping current, permitting longer life from a power supply. The MAX31342 supports 6pF high-ESR crystals, which broaden the pool of usable crystals for the devices. This device is accessed through an I2C serial interface. An integrated power-on reset function ensures deterministic default register status upon power-up. Other features include two time-of-day alarms, interrupt outputs, a programmable square-wave output, and a serial bus timeout mechanism.
