The DS8007 and Smart Card Interface Fundamentals
The DS8007 is a multiprotocol, low-cost, dual, smart card interface that supports all ISO 7816, EMV™, and GSM11-11 requirements. This one mixed-signal peripheral manages all .The SERCOM USART features an ISO/IEC 7816-compatible operating mode. This mode permits interfacing with smart cards and Security Access Modules (SAM) communicating through an .The ISO 7816 standard defines the necessary protocols to communicate with a smart card. Although the communication software is tested with TimeCOS, the basic communication protocol (ISO 7816, T = 0) implemented in this application note is common with all smart cards. 2012 Freescale Semiconductor, Inc.
The DS8007 is a multiprotocol, low-cost, dual, smart card interface that supports all ISO 7816, EMV™, and GSM11-11 requirements. This one mixed-signal peripheral manages all the details of the interface between a microcontroller and two, independent smart cards.
The SERCOM USART features an ISO/IEC 7816-compatible operating mode. This mode permits interfacing with smart cards and Security Access Modules (SAM) communicating through an ISO 7816 link. Both T=0 and T=1 protocols defined by the ISO 7816 specification are supported.
The USART Smartcard mode supports asynchronous protocol Smartcards as defined in the ISO 7816-3 standard. With the Smartcard mode enabled, the USART must be configured as: • eight data bits plus parity; • 0.5 or 1.5 stop bits. A 5-bit prescaler and the Smartcard clock generator provide the clock to the Smartcard. This application note describes the fundamentals of the contact type smart cards, and how they are communi-cated using the PIC microcontroller. It also explains the T = 0 and T = 1 protocols, which are widely used in contact type smart card communications.A smart card reader was developed using the STR710 ARM7TDMI powered microcontroller and a basic HW to interface 5V powered smart card. The Smart Card Library was developed in order to support ISO7816-3/4 specification.
SAM L22 Device Configuration for Smart Card Interface. Smart card can be interfaced with MCU using ISO7816 protocol, a standard for electronic identification cards with contacts. This section explains the MCU interface detail such as required I/O pins, USART Clock details and ISO7816 Mode in SERCOM Module.
Most of ISO7816-3 is important for reader manufacturers or developers who want to establish a communication with a smart card on a very low level (the signal level). Going through ISO 7816-3 you will see what’s involved in writing your own I/O software.A NOTE ON PARITY: A parity bit is used as a very simple quality check for the accuracy of the transmitted binary data. The designer of the format program will decide if each parity bit should be even or odd. A selected group of data bits will be united with one parity bit, and the total number of bits should result in either an even or odd number.
