The DS3234S#T&R from Analog Devices is a highly accurate SPI bus Real Time Clock (RTC) designed for precise timekeeping. It integrates a temperature-compensated crystal oscillator (TCXO) and crystal, ensuring accuracy of ±2ppm from 0°C to +40°C and ±3.5ppm from -40°C to +85°C.
This device completely manages all timekeeping functions, counting seconds, minutes, hours, day, date, month, and year, with leap year compensation valid up to 2099. It includes 256 bytes of battery-backed SRAM, maintaining memory contents during main power loss. The RTC operates in either 24-hour or 12-hour format with an AM/PM indicator. It also provides two programmable time-of-day alarms and a programmable square-wave output.
Designed for ease of integration, the DS3234S#T&R features a simple serial SPI interface that connects to most microcontrollers. It supports SPI bus modes 1 and 3 with a 4MHz clock speed. The device operates within a voltage range of 2V to 3.8V and consumes low power, extending battery backup run time. It is available in a 20-pin SOIC package suitable for surface mounting.
Applications for this RTC include servers, utility power meters, telematics, and GPS systems where precise and reliable timekeeping is critical.
