产品概述
The DS3231SN#T&R from Maxim Integrated Products is an extremely accurate I2C-integrated RTC/TCXO/crystal in 16 pin SOIC package. It is a low-cost, extremely accurate I2C RTC with an integrated TCXO and crystal. It incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. 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 the 24/12hr format with an AM/PM indicator. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, to provide a reset output and to automatically switch to the backup supply when necessary.
Supply voltage range is 2.3V to 5.5V
Operating temperature range from -40°C to +85°C
±3.5ppm accuracy (-40°C to +85°C)
Digital temp sensor output of ±3°C accuracy
Register for aging trim
RST(active-low) output/pushbutton reset debounce input
Two time of day alarms
Programmable square wave output signal, address and data are transferred serially
Battery-backup input for continuous timekeeping, Underwriters Laboratories? (UL) recognized
应用
时钟与计时
