Add To BomDS1687-5+ General Description
The DS1685/DS1687 are real-time clocks (RTCs) designed as successors to the industry-standard DS1285,DS1385, DS1485, and DS1585 PC RTCs. These devices provide the industry-standard DS1285 clock function with either +3.0V or +5.0V operation. The DS1685 also incorporates a number of enhanced features including a silicon serial number, power-on/off control circuitry, 242 bytes of user NV SRAM, and 32.768kHz output for sustaining power management activities.

- Y2K Compliant
- +3V or +5V Operation
- 64-Bit Silicon Serial Number
- Power-Control Circuitry Supports System Power-On from Date/Time Alarm or Key Closure
- 32kHz Output for Power Management
- Crystal-Select Bit Allows RTC to Operate with 6pF or 12.5pF Crystal
- SMI Recovery Stack
- 242 Bytes Battery-Backed NV RAM
- Auxiliary Battery Input
- RAM Clear Input
- Century Register
- Date Alarm Register
- Compatible with Existing BIOS for Original DS1287 Functions
- Available as Chip (DS1685) or Stand-Alone Encapsulated DIP (EDIP) with Embedded Battery and Crystal (DS1687)
- Timekeeping Algorithm Includes Leap-Year Compensation Valid Through 2099
Application
- Embedded Systems
