The DS3234S# from Analog Devices is a highly accurate SPI bus real-time clock (RTC) designed for precise timekeeping functions. It features an integrated temperature-compensated crystal oscillator (TCXO) and crystal, enhancing long-term accuracy.
This RTC manages all timekeeping functions, including seconds, minutes, hours, day, date, month, and year, with leap year compensation valid up to 2099. It includes two programmable time-of-day alarms and a programmable square-wave output. The device integrates 256 bytes of battery-backed SRAM, ensuring data retention during main power loss.
The DS3234S# operates with a supply voltage range of 2V to 3.8V and has an operating temperature range of 0°C to 70°C. It communicates via a simple serial SPI interface, making it easy to connect to most microcontrollers. The RTC is housed in a 20-pin SOIC package suitable for surface mounting.
Key features include an accuracy of ±2ppm from 0°C to +40°C and ±3.5ppm from -40°C to +85°C. It also provides a digital temperature sensor output with ±3°C accuracy. The device supports SPI bus speeds up to 4MHz and includes a battery-backup input for continuous timekeeping.
The operating voltage range is from 2V to 3.8V.
It is packaged in a 20-SOIC surface-mount package.
The operating temperature range is from 0°C to 70°C.
It is marked as RoHS3 compliant, but this status is unverified.
