EconoRAM Time Chip
DS2404
020998 1/25
FEATURES
4096 bits of nonvolatile dual–port memory including
real time clock/calendar in binary format, program-
mable interval timer, and programmable power–on
cycle counter
1–Wire
TM
interface for MicroLAN
TM
communication
at 16.3k bits per second
3–wire host interface for high–speed data commu-
nications at 2M bits per second
Unique, factory–lasered and tested 64–bit registra-
tion number (8–bit family code + 48–bit serial number
+ 8–bit CRC tester) assures absolute traceability
because no two parts are alike
Memory partitioned into 16 pages of 256–bits for
packetizing data
256–bit scratchpad with strict read/write protocols
ensures integrity of data transfer
Programmable alarms can be set to generate inter-
rupts for interval timer, real time clock, and/or cycle
counter
16–pin DIP, SOIC and SSOP packages
Operating temperature range from –40

DESCRIPTION
The DS2404 EconoRAM Time Chip offers a simple so-
lution for storing and retrieving vital data and time in-
formation with minimal hardware. The DS2404 con-
tains a unique lasered ROM, real–time clock/calendar,
interval timer, cycle counter, programmable interrupts
vided 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 Semi-
conductor 3–wire interface. With either interface, a strict
protocol for accessing the DS2404 insures data integri-
ty. Utilizing backup energy sources, the data is nonvola-
tile and allows for stand-alone operation.
The DS2404 features can be used to create a stop-
watch, alarm clock, time and date stamp, logbook, hour
meter, calendar, system power cycle timer, expiration
timer, and event scheduler.
