Details

GENERAL DESCRIPTIONThe DS1337 serial real-time clock is a low-power clock/calendar with two programmable time-of-day alarms and a programmable square-wave output. Address and data are transferred serially via a 2-wire, bidirectional bus. 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 either the 24-hour or 12-hour format with AM/PM indicator.FEATURES■ Real-Time Clock (RTC) Counts Seconds, Minutes, Hours, Day, Date, Month, and Year with Leap-Year Compensation Valid Up to 2100■ Two-Wire Serial Interface■ Two Time-of-Day Alarms■ Oscillator Stop Flag■ Programmable Square-Wave Output – Defaults to 32kHz on Power-Up■ Available in 8-Pin DIP, SO, or μSOPAPPLICATIONS Handhelds (GPS, POS Terminal, MP3 Player) Consumer Electronics (Set-Top Box, VCR/Digital Recording) Office Equipment (Fax/Printer, Copier) Medical (Glucometer, Medicine Dispenser) Telecommunications (Router, Switcher, Server) Other (Utility Meter, Vending Machine, Thermostat, Modem)

FAQs

What is DS1337S?

The DS1337S is a low-power, I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) designed by Maxim Integrated. It is ideal for applications requiring accurate timekeeping and calendar functions, such as smart meters, data loggers, and medical instruments.

How Does DS1337S Work?

The DS1337S works by keeping track of the current time and date with high accuracy using its integrated TCXO. It communicates with a microcontroller or system through the I2C interface, allowing for easy integration into digital systems. The RTC operates with low power consumption, making it suitable for battery-powered devices.

How Many Pins does DS1337S have and What are the Functions of the Pinout Configuration?

The DS1337S is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VCC: Positive power supply pin.
  • GND: Ground pin.
  • SCL: Serial clock input/output for I2C communication.
  • SDA: Serial data input/output for I2C communication.
  • X1, X2: Connections for an external crystal oscillator or resonator.
  • NC: No-connect pin (not internally connected).

What are the Pros and Cons of DS1337S?

Pros:

  • High Accuracy: Provides precise timekeeping and calendar functions.
  • Low Power Consumption: Operates with low power, suitable for battery-powered devices.
  • I2C Interface: Allows for easy communication and integration with microcontrollers or digital systems.
  • Integrated TCXO: Includes a temperature-compensated crystal oscillator for reliable timekeeping.
  • Compact Package: The 8-pin SOIC package is space-efficient, suitable for compact designs.

Cons:

  • External Crystal Required: Requires an external crystal oscillator or resonator for operation.
  • Limited Features: May not have advanced features compared to more complex RTCs.
  • Configuration Complexity: Configuration and setting adjustments may require attention to I2C communication protocols.

Are There Any Equivalents/Alternatives to DS1337S for Recommendation?

  • The DS3231 from Maxim Integrated is a similar RTC with additional temperature sensor and alarms.
  • Alternatives to the DS1337S include the PCF2129 from NXP Semiconductors and the MCP7940N from Microchip Technology.
