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
®
, and B-CAS applications. Additionally, the device is designed for
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 microcontroller for developing smart card applications
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.
