DS3234SN#T&R Description

Short technical summary and product information.

The DS3234SN#T&R is a highly accurate SPI bus Real-Time Clock (RTC) manufactured by Analog Devices. It integrates a temperature-compensated crystal oscillator (TCXO) and crystal, ensuring precise timekeeping. The device manages all timekeeping functions, counting seconds, minutes, hours, day, date, month, and year, with leap year compensation valid up to 2099.

 

Key electrical specifications include an operating voltage range of 2V to 3.8V and a low operating current of 120µA to 160µA. The interface is SPI, supporting modes 1 and 3. It also features 256 bytes of battery-backed SRAM, which maintains data integrity during main power loss when connected to the VBAT pin. The device offers two programmable time-of-day alarms and a programmable square-wave output.

 

This RTC is designed for surface mount applications and comes in a 20-pin SOIC package. It operates reliably within a temperature range of -40°C to +85°C. The integrated digital temperature sensor provides readings with ±3°C accuracy. The DS3234SN#T&R is suitable for applications requiring precise timekeeping, such as servers, utility power meters, telematics, and GPS systems.
