The DS8007 provides all electrical signals necessary to physically interface a microcontroller with two
individual smart cards. The device also contains a dedicated internal sequencer that controls automatic
card activation and deactivation, and an ISO UART for data communication. In addition, the DS8007
contains charge pumps and voltage regulators that allow it to operate from a 2.7V to 6.0V supply voltage
and produce two independent smart card supply voltages, either of which can be 1.8V, 3.0V, or 5.0V.
Communication with a microcontroller is provided by a standard parallel 8-bit bus in a multiplexed or a
nonmultiplexed configuration.
Software Setup
For this application note, a Dallas Semiconductor Microcontroller Tool Kit (MTK) and Keil's PK51
Professional Developer's Tool Kit software should be installed and operational on your PC. Both software
packages are included with the DS8007 EV kit. The following sections describe the steps for installing
these applications. If either or both of these applications are already installed on your PC, the section(s)
describing their installation can be ignored.
Installing the Microcontroller Tool Kit
1. Insert the DS8007 EV kit install CD into your computer's CD-ROM drive. The CD will autoboot and
display the DS8007 EV kit welcome screen. If the CD-ROM does not autoboot, browse the CD root
folder, and double-click on the index.html file.
2. Click the "Install MTK" button, and click the "Run" button to begin installation.
3. During the MTK installation, select the default settings.
Note:
security warnings may appear,
depending on your web browser security settings and your version of Windows®. If this does occur,
simply acknowledge the warning, and proceed with the installation.
Installing the Keil Professional Developer's Tool Kit
1. To install Keil's PK51 Professional Developer's Tool Kit, insert the Keil Microcontroller Development
Tools CD (included with the DS8007 EV kit) into your computer's CD-ROM drive. The CD will
autoboot and display the main menu. If the CD-ROM does not autoboot, browse the CD root folder,
and double-click on the setup.exe file.
2. At the main menu, select "Install Evaluation Software," and then select the "C51 Compiler (Eval
Tools)."
3. Follow the on-screen instructions to install the Keil tools on your PC.
Hardware Setup
Configuring the DS8007 EV kit board requires that you properly set the jumpers, connect its serial port to
the PC, and connect the power supply. These steps are detailed below.
1. Connect jumpers 1 through 13 as shown in
Figure 2
and further described in
Table 1
.
2. Connect one end of the supplied serial cable to the board's DB-9 connector (J6) and the other end
to the COM port of your PC.
3. Connect the 5V, regulated (±5%), 300mA, 2.5mm center positive, power supply included with the
EV kit to the board's J7 power connector.
