APPLICATION NOTE 5388
Getting Started with the DS8005 Evaluation Kit
Apr 01, 2013
Abstract: This application note describes how to build, debug, and run applications on the on-board MAXQ622
microcontroller to interface with the DS8005 dual smart card interface. This is demonstrated in both IAR
Embedded Workbench and the Rowley CrossWorks IDE, using sample code provided with the kit.
Introduction
The
DS8005
dual smart card interface is a low-cost, dual analog front-end (AFE) for an IC card reader
interface that needs to communicate with two smart cards in a mutually exclusive fashion. The analog interface
is designed for use in ISO 7816, EMV
applications where the C4/C8 (AUX1/AUX2) contacts are not required on either card interface. The DS8005 is
designed to be used with microcontrollers that contain an ISO 7816 UART, or have the bandwidth to run this
protocol in software by bit-banging IO ports.
In the DS8005 evaluation kit (DS8005-KIT), the DS8005 is provided in a 28-pin SOIC package. A smaller 28-
pin TSSOP package is also available.
Setting Up the DS8005 Evaluation Kit
A photo of the DS8005 evaluation kit board is provided in Figure 1. The following hardware components are
contained in the evaluation kit and are used for implementing and verifying the demonstrated program:
1. DS8005 evaluation kit board
2. On-board
MAXQ622
3. USB-to-JTAG dongle for programming the MAXQ622
4. One ACOS3 smart card
5. Two card sockets (one smart card and one SIM/SAM card)
6. 2-line liquid-crystal display (LCD) screen for the user interface
7. Level-shifted RS-232 interface for debugging and the user interface
8. Pushbuttons for reset and user input
9. Regulated power supply (5V, ±5%, 300mA, center positive)
Table 1 shows all the jumpers and includes a description of what each setting does. Settings highlighted in
blue indicate the default settings. See Figure 2 for jumper locations.

The driver package can be downloaded from this page and will be named similar to “CDM20814_WHQL_Certified.zip”, where the five-digit number depends on the exact...

Determining the COM Port Location of the USB-to-Serial Interface The USB-to-serial interface provided by the FT232RL chip on the USB-to-JTAG dongle uses the virtual COM port (VCP) device model on Windows. This means that the USB-to-serial bridge appears as a standard COM port and can be used by any Windows application that has the ability to communicate over a COM port.
- Page 6 executable, check the DRVSTORE directory, usually found in the Windows directory under the System32 subdirectory. If you see directories named ftdibus_<xxxxx> or ftdiport_<xxxxx>, where <xxxxx> is a random- appearing string of hex digits, delete these directories before running the CDM20814_Setup.exe executable. This will remove the preinstalled copies of the drivers and allow the drivers to reinstall cleanly.
