DS2404 EconoRAM Time Chip

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.
