Input voltage3.3 V
IC revision1.01

Description

The QCIOT56-ISL12022EVZ device is a low power real time clock (RTC) with an embedded temperature sensor and crystal. Device functions include oscillator compensation, clock/calendar, power fail and low battery monitors, brownout indicator, one-time, periodic or polled alarms, intelligent battery backup switching, Battery Reseal™ function and 128 bytes of battery-backed user SRAM. Backup battery current draw is less than 1.6μA over the temperature range. The RTC tracks time with separate registers for hours, minutes, and seconds. Daylight Savings time adjustment is done automatically, using parameters entered by the user. Power fail and battery monitors offer user-selectable trip levels.

Features

  • On-chip oscillator temperature compensation
  • Embedded 32.768kHz quartz crystal in the package
  • 10-bit digital temperature sensor output
  • 15 selectable frequency outputs
  • Interrupt for alarm or 15 selectable frequency outputs
  • Automatic backup to battery or supercapacitor
  • Standardized Type 6A Pmod connector supports I2C extended interface
  • Dual connectors allow pass-through signals for daisy chained solutions
  • Software support in e2 studio minimizes development time with one-click code generation

Typical applications

  • Connected Android-Based Vehicle Instrument Cluster
  • Digital Cameras, Printers and Copiers
  • Utility Meters, POS Equipment
