DS1685Q-3 Real-Time Clock For PC-Style Timekeeping And NV Storage

DS1685Q-3 is used when a system needs persistent time-of-day plus small, battery-backed storage for settings and service records. It is a real-time clock designed as a successor to PC-style RTC functions, and it integrates features useful for embedded platforms that still want that familiar programming model. DS1685Q-3 includes 242 bytes of battery-backed NV RAM and provides a 32.768kHz output that can support power management timing. It also incorporates power-control support such as wake events based on alarms or external key closure behavior, depending on system design. Use DS1685Q-3 in industrial PCs, legacy controller boards, and retrofit systems where timekeeping must survive power removal. Keep the crystal network tight and guard it from digital noise to preserve accuracy. Request a quote for DS1685Q-3.
