The Dallas Semiconductor DS1687-3 is a versatile Real-Time Clock (RTC) designed for various applications including embedded systems, utility meters, and security systems. It incorporates the industry-standard DS1287 PC clock functionality with enhanced features.
Key features include Y2K compliance, operation with either 3V or 5V power supplies, and a 64-bit silicon serial number. The device offers 242 bytes of battery-backed Non-Volatile RAM for data storage, an auxiliary battery input, and a RAM clear input. It also includes a power-control circuitry that supports system power-on from a date/time alarm or key closure, and a 32kHz output for power management.
The timekeeping algorithm includes leap-year compensation valid through 2099. The DS1687-3 is available in a DIP package suitable for through-hole mounting. It is compatible with existing BIOS for original DS1287 functions.
