MAX31329ELB+

MAX31329ELB+ is a low-current, real-time clock with I2C, power management, and integrated crystal. It is a timekeeping device that provides timekeeping current in nanoamperes, thus extending battery life. It incorporates an integrated 32.768KHz crystal, which eliminates the need for an external crystal. It features one digital Schmitt trigger input (DIN) and generates an interrupt output on a falling or rising edge of this digital input. Other 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. Applications include industrial equipment, test and measurement equipment, energy meters, medical devices, portable instruments, factory automation, IoT devices, surveillance cameras, servers.
