DS28E80 Evaluation System
Evaluates: DS28E80
General Description
The DS28E80 evaluation system (EV system)
consists of a single evaluation kit (EV kit) that includes a
package of five DS28E80 devices in a 6-pin TDFN
package, a DS9120Q+ socket board with RJ11 cable, and
a DS9481R-3C7+ USB-to-1-Wire
®
/iButton
®
adapter with
USB cable for PC connectivity. This EV system provides
the special hardware and software system to exercise
the features of the DS28E80. The evaluation software
runs under Windows
®
8, Windows 7, Windows Vista
®
,
and Windows XP
®
operating systems (32-bit and 64-bit
versions). It provides a handy user interface to exercise
the DS28E80 features.
The DS28E80 is a user-programmable nonvolatile
memory chip. In contrast to the floating-gate storage cells,
the DS28E80 employs a storage-cell technology that is
gamma radiation resistant. The DS28E80 has 248 bytes
of user memory, organized in blocks of 8 bytes. Individual
blocks can be write-protected. Each memory block can be
written eight times. The DS28E80 communicates over the
single-contact 1-Wire bus at standard speed or overdrive
speed. Each device has its own guaranteed unique 64-bit
registration number factory programmed into the chip. The
communication follows the 1-Wire protocol with a 64-bit
registration number acting as node address in the case of
a multiple-device 1-Wire network.

Note:
Pin 1 is indicated by a white dot on the DS9120Q+ PCB.
3)
Orientation in the socket
a) Insert one of the DS28E80 devices into the
TDFN-EP socket on the DS28E80 EV kit board.
b)
Close the burn-in socket.
Connect the DS9481R-3C7+ with the DS9120Q+
using the RJ11 cable assembly.
Connect the DS9481R-3C7+ in a vacant USB port
on the PC using the USB type-A to Mini-USB type-B
cable.
a) Unzip the
DS28E80_EVKit_Rev2.zip
file to a
known location.
Open the
Installation
folder and double-click the
Setup.exe
file.
When properly installed, the graphical user interface
(GUI) window shown in Figure 4 should appear.
Procedure
1)
2)
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Install the 1-Wire drivers. See the
Installing 1-Wire
Drivers
section for instructions.
The PL-2303 Prolific Driver needs to be installed.
See the
Installing the Prolific Device Driver for the
DS9481R-3C7+
section for instructions.
a) Insert the DS28E80 in the TDFN-EP socket on
the DS9120Q+ EV board. See Figure 3 for the pin
configuration.

8)
To start communicating with the part, it is necessary
to have the DS9481R adapter connected and have a
part placed into the DS9120 socket. Once adapter is
connected, select
Device → Connect.
a) The
Connect
feature can also be used to refresh
the connection settings. This is helpful for the user
if a new device is attached to the DS9120 adapt-
er. The software needs to reconfigure the number
of devices in the network and be ready to work
with the new device. Clicking the
Connect
option
refreshes the selections (Figure
5).
9)
Under
Device → Setup,
the user can review the
settings, change the device, port, 1-Wire speed, or
review the selected device ROM ID (Figure
6).
10)
If more than one device is in the 1-Wire network, it
will be displayed under
Device → Setup → Device
Selection
(Figure
7).
From there, the user can select
any DS28E80 in the 1-Wire network. The new select-
ed device ROM ID will be displayed under
Device →
Setup → Selected Device ROM ID.
