MAX31328

±3.5ppm, I²C RTC with Integrated Crystal and

Power Management

General Description

Benefits and Features

The MAX31328 is a low-cost, extremely accurate, I²C

real-time clock (RTC) with an integrated temperature-

compensated crystal oscillator (TCXO) and crystal. The

device incorporates a battery input and maintains

accurate timekeeping when main power to the device is

interrupted. The integration of the crystal resonator

enhances the long-term accuracy of the device and

eliminates the external crystal requirement in the

system. The MAX31328 is available in a 10-pin LGA

package.

•

Highly Accurate RTC Completely Manages All

Timekeeping Functions

•

Complete Clock Calendar Functionality,

Including Seconds, Minutes, Hours, Day, Date,

Month, and Year with Leap-Year Compensation

Up to 2100

•

Low Timekeeping Battery Current of 660nA

Timekeeping Accuracy ±3.5ppm

(±0.302 seconds/day) from -40°C to +85°C

Two Time-of-Day Alarms

Temperature-Compensated Programmable

Square-Wave Output

•

The RTC maintains 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 either 24-hour or 12-hour format with

an AM/PM indicator. Two programmable time-of-day

alarms and a programmable square-wave output are

provided. Address and data are transferred serially
