It keeps time in YY-MM-DD-dd and HH:MM:SS (12/24 hr) formats, with 256 bytes of SRAM for user data, and generates alarms and square-wave outputs. The on-chip TCXO eliminates the need for an external crystal and trimming capacitors, saving board space and improving long-term accuracy over temperature — a key advantage for industrial and outdoor equipment where the ambient swings from -40°C to 85°C. ## Lifecycle and sourcing reality The DS3234SN#T&R carries an Active product status and is ROHS3 compliant.","metaTitle":"Maxim DS3234SN#T&R RTC Clock/Calendar, SPI, -40 to 85°C","metaDescription":"Maxim DS3234SN#T&R real-time clock with integrated TCXO/crystal, SPI interface, 256B SRAM, 20-SOIC.

The DS3234SN#T&R adds an integrated TCXO and crystal, which the DS3232 lacks — that changes the external BOM and accuracy profile. Verify pin compatibility against your layout before substituting."},{"question":"How accurate is the DS3234SN#T&R real-time clock?","answer":"The integrated TCXO and crystal deliver temperature-compensated timekeeping across the full -40°C to 85°C operating range. The datasheet specifies accuracy better than ±2 ppm from 0°C to 40°C and ±3.5 ppm from -40°C to 85°C — roughly 1 minute per year drift at room temperature."},{"question":"What is the DS3234SN#T&R's listed package?","answer":"The DS3234SN#T&R comes in a 20-SOIC wide-body package (0.295-inch, 7.50mm width), surface-mount.
