DESCRIPTION
The DS1413 Passive Serial Port iButton Holder is a sim-
ple, lowcost adapter which performs RS232C (
±
12V)
level conversion, allowing a non–EPROM iButton to be
read and written directly. It can also read all EPROM–
based iButtons. The serial port must support a data
transmission rate of 115.2 kbits/s in order to create the
1–Wire time slots correctly. Nearly all PCs and several
other hardware platforms support the required bit rate
and are fully compatible with the DS1413. Since an
eight bit character (6 data bits plus start– and stop bit) on
the RS232C port operating at 115.2 kbits/s is used to
form a single 1–Wire time slot, the maximum effective
1–Wire transfer rate is 14.4 kbits/s (regular speed). The
DS1413 has a DS9098 retainer for a single F5 Micro-
Can and can replace the DS9097 COM Port Adapter in
applications that use only a single iButton. Multiple iBut-
tons can be connected to the DS1413 using standard
MicroLAN Cables and button holders (see DS1401 and
DS1402x data sheets).
The DS1413 does not support the strong pull–up which
is required to run the Crypto iButton. For applications
requiring a strong 5V pull–up see DS1411. Details on
the operation of the DS1413 are found in Application
Note 74, Section V.
