The DS2404 1-Wire® EconoRAM time chip offers a simple solution for storing and retrieving vital data and time information with minimal hardware. The DS2404 contains a unique lasered ROM, real-time clock/calendar, interval timer, cycle counter, programmable interrupts, and 4096-bits of SRAM. Two separate ports are provided for communication: 1-Wire and 3-wire. Using the 1-Wire port, only one pin is required for communication, and the lasered-ROM can be read even when the DS2404 is without power. The 3-wire port provides high-speed communication using the traditional Dallas Semiconductor 3-wire interface. With either interface, a strict protocol for accessing the DS2404 ensures data integrity. Utilizing backup energy sources, the data is nonvolatile (NV) and allows for stand-alone operation. The DS2404 features can be used to create a stopwatch, alarm clock, time and date stamp, logbook, hour meter, calendar, system power-cycle timer, expiration timer, and event scheduler.
4096 bits of nonvolatile dual-port memory including real-time clock/calendar in binary format, programmable interval timer, and programmable power-on cycle counter
1-Wire interface for communication at 16.3kbps
3-wire host interface for high-speed data communications at 2Mb/s
Unique, factory-lasered and tested 64-bit registration number assures absolute traceability because no two parts are alike
Programmable alarms can be set to generate interrupts for interval timer, real-time clock, and/or cycle counter
