Description
The DS2404 EconoRAM Time Chip offers a simple solution for storing and retrieving vital data and time information with minimal hardware. It contains a unique lasered ROM, real-time clock/calendar, interval timer, cycle counter, programmable interrupts, and 4096-bits of SRAM. The DS2404 has two separate ports for communication, 1-Wire and 3-wire. The 1-Wire port requires only one pin for communication and allows reading of the lasered ROM even without power. The 3-wire port provides high-speed communication using the traditional Dallas Semiconductor 3-wire interface. The DS2404 ensures data integrity through a strict protocol for accessing the device. With backup energy sources, the data is nonvolatile and allows for standalone operation.
