FEATURES  
PIN ASSIGNMENT  
§ 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-WireTM interface for MicroLAN  
communication at 16.3k bits per second  
§ 3-wire host interface for high-speed data  
communications at 2M bits per second  
§ Unique, factory-lasered and tested 64-bit  
registration number (8-bit family code + 48-  
bit serial number + 8-bit CRC tester) assures  
absolute traceability because no two parts are  
alike

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.
