It keeps time to within a few minutes per year across the full -40°C to 85°C industrial range — no external trimming needed. On-chip 256B SRAM stores calibration or configuration data without tying up a separate EEPROM. The alarm output and programmable square wave save a timer channel on the host MCU. ## Lifecycle and compliance The DS3234SN# is listed as Active — no end-of-life notice, no last-time-buy pressure. Fully ROHS3 compliant, so it passes European and domestic RoHS requirements without exemption paperwork.","metaTitle":"Maxim DS3234SN# RTC Clock/Calendar, SPI, -40°C to 85°C","metaDescription":"Maxim DS3234SN# RTC Clock/Calendar with SPI interface, TCXO/crystal, 256B SRAM, alarm, square wave output.
