MAX31343EKA+T

MAX31343EKA+T is a MAX31343 is a low-cost, extremely accurate, I2C, RTC with integrated MEMS oscillator in 2.1mm x 2.3mm, 8-Pin WLP package. The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the MEMS resonator enhances the long-term accuracy of the device and eliminates the external crystal requirement in the system. The RTC maintains seconds, minutes, hours, day, date, month, year, and century information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year up to year 2199. The clock operates in the 24-hour format. Other features includes two programmable time-of day alarms, interrupt output, uncompensated programmable clock output, and temperature-compensated programmable square-wave output. Suitable for industrial, action cameras, communications, handheld instrumentation, power meters and wearables applications.
