DESCRIPTION
The DS2404 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 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.
