13.56 MHz RFID Protocol on

Stellaris®

The Stellaris® 13.56 MHz RFID Wireless Kit from Texas

Instruments is a complete system solution for enabling

RFID capabilities in customers' end equipment. The

solution works with two of our most popular Stellaris

microcontroller development kits (each sold separately), a

Stellaris EM2 expansion board, and TI's TRF7960TB HF

RFID Reader Module along with all necessary firmware

and software to provide a compelling RFID development

environment and interactive system demonstration.

This RFID technology has been selected for most

contactless smart card projects and as a result, become

the most successful one within the automatic fare

collection industry. In addition, this technology successfully

addresses other applications such as loyalty, road tolling,

access management, and gaming. This solution is based

on ISO/IEC 14443 Type A which is the international

standard for proximity card systems consisting of card and

reader components with a typical read/write distance of 10

cm (4 inches).

The Stellaris® 13.56 MHz RFID solution allows software

application developers to become familiar with the

operation of the TRF7960TB Multi-Standard Fully

Integrated 13.56 MHz RFID reader IC using their Texas

Instruments’ Stellaris DK-LM3S9B96 or DK-LM3S9D96

development platforms (each sold separately) without

having to be concerned about the RF portion of the system.

The Stellaris EM2 expansion board (DK-LM3S9B96-EM2)

facilitates the connection of up to 2 wireless expansion

modules using SPI as the primary interface to the

TRF7960TB module.
