Product Overview

The DS3234SN#T&R from Maxim Integrated Products is an extremely accurate SPI bus RTC with integrated crystal and SRAM in 20 pin SOIC package. It is a low-cost, extremely accurate SPI bus RTC with an integrated TCXO and crystal. It incorporates a precision, temperature compensated voltage reference and comparator circuit to monitor VCC. The integration of crystal resonator enhances long-term accuracy of device. The DS3234 also integrates 256 bytes of battery-backed SRAM. The RTC maintains seconds, minutes, hours, day, date, month and year information. The date at end of month is automatically adjusted for months with fewer than 31 days including corrections for leap year. The clock operates in 24/12-hour format with AM/PM indicator. 2 programmable time-of-day alarms and a programmable square-wave output are provided. Address and data are transferred serially by an SPI bidirectional bus. It is used in servers, telematics, utility power meters and GPS.
  • Supply voltage range from 2V to 5.5V (VCC), 2V to 3.8V (VBAT)
  • Operating temperature range from -40°C to +85°C
  • Highly accurate RTC with integrated crystal and SRAM manages all timekeeping functions
  • Accuracy of ±3.5ppm
  • Digital temperature sensor output is ±3°C accuracy
  • Register for aging trim, RST (active low) input/output
  • Simple serial interface connects to most microcontrollers
  • 4MHz SPI Bus supports modes 1 and 3
  • Battery-backup input for continuous timekeeping, low power operation extends battery backup time
  • Underwriters Laboratories® (UL) recognized
