Extremely Accurate SPI Bus RTC with  
Integrated Crystal and SRAM  
DS234  
General Description  
Features  
♦ Accuracy 2ppm from 0°C to +40°C  
The DS3234 is a low-cost, extremely accurate SPI™ bus  
real-time clock (RTC) with an integrated temperature-com-  
pensated crystal oscillator (TCXO) and crystal. The  
DS3234 incorporates a precision, temperature-compen-  
sated voltage reference and comparator circuit to monitor  
♦ Accuracy 3.5ppm from -40°C to +85°C  
♦ Battery Backup Input for Continuous  
Timekeeping  
♦ Operating Temperature Ranges  
Commercial: 0°C to +70°C  
Industrial: -40°C to +85°C

input for generating a µP reset. The device switches to the  
backup supply input and maintains accurate timekeeping  
when main power to the device is interrupted. The integra-  
tion of the crystal resonator enhances the long-term accu-  
racy of the device as well as reduces the piece-part count  
in a manufacturing line. The DS3234 is available in com-  
mercial and industrial temperature ranges, and is offered  
in an industry-standard 300-mil, 20-pin SO package.  
♦ Two Time-of-Day Alarms  
♦ Programmable Square-Wave Output  
♦ 4MHz SPI Bus Supports Modes 1 and 3  
♦ Digital Temp Sensor Output: 3°C Accuracy  
♦ Register for Aging Trim  
The DS3234 also integrates 256 bytes of battery-backed  
SRAM. In the event of main power loss, the contents of  
the memory are maintained by the power source con-

pin. The RTC maintains seconds,

minutes, hours, day, date, month, and year information.  
The date at the end of the month is automatically adjust-  
ed for months with fewer than 31 days, including correc-  
tions for leap year. The clock operates in either the  
24-hour or 12-hour format with AM/PM indicator. Two  
programmable time-of-day alarms and a programmable  
square-wave output are provided. Address and data are  
transferred serially by an SPI bidirectional bus.
