Paquete SO-8

Características

  • Accurate time and date tracking
  • Battery-backup support
  • Two time-of-day alarms
  • Programmable square-wave output

Aplicaciones

  • Data logging systems
  • Industrial controllers
  • Security and access systems
  • Smart meters

The DS1307ZN+T&R from Analog Devices (formerly Maxim) is an I2C real-time clock operating from 2.3-5.5V in a SO-8 package. It provides accurate time and date information with battery backup for embedded systems requiring persistent timekeeping.

The RTC uses a crystal oscillator (external 32.768kHz for DS1307, internal TCXO for DS3231) as the time base. A counter chain divides the oscillator frequency to generate seconds, minutes, hours, day, date, month, and year. The DS3231 integrates a temperature-compensated crystal oscillator (TCXO) achieving plus or minus 2ppm accuracy. Battery backup (VBAT pin) maintains timekeeping when main power is removed.
