It tracks time in HH:MM:SS (12/24 hr) and date in YY-MM-DD-dd format, with built-in alarm, daylight savings, and leap year compensation. The 8KB NVSRAM retains data through the battery backup pin, making it a fit for embedded systems that need both timekeeping and small persistent storage without external EEPROM. ## Lifecycle and sourcing reality The DS17885S-5+ carries an Active lifecycle status and is ROHS3 compliant, so it remains a current-production part with no near-term end-of-life signal. For buyers filling a BOM line, this part is a stable, in-production choice with no LTB risk.","metaTitle":"DS17885S-5+ RTC Clock/Calendar, 8KB NVSRAM, 5V, 24-SOIC","metaDescription":"DS17885S-5+ parallel-interface RTC with 8KB NVSRAM, alarm, daylight savings. 4.5V-5.5V supply, battery backup 2.5V-3.7V. 0°C to 70°C.
