DS2404S–C01
Dual Port Memory Plus Time
DS2404S–C01
020998 1/2
FEATURES
Bridge for electronic equipment to the 1–Wire Micro-
LAN
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 interface for MicroLAN 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

DESCRIPTION
In order to provide universal access to the MicroLAN,
the DS2404S–C01 Dual Port Memory Plus Time has
been developed. This device has both 1–Wire and a
3–Wire
serial
microcontroller
DS2404S–C01 can be used to make complex functions
involving microcontrollers behave as if they were
iButtons.
interface.
The
Being a custom–ROM version of the DS2404, the
DS2404S–C01 has the family code 84H. In addition to
this, the 12 most significant bit of the serialization field
are coded 001H, leaving 28 bits for serialization. The
communication with the DS2404S–C01 through the
1–Wire port is identical to the DS1994; all functions of
the DS1994 are available.
