Implementation of the ISO15693 Protocol in the TI
TRF 796x
ShreHarsha Rao RFID Systems/ASP
ABSTRACT
This application note discusses the anti-collision sequence of the ISO15693
standard implemented in the MSP430F156 (a 16-bit ultra-low power
microcontroller from the TI MSP430 family) used with Texas Instruments’
TRF796x, a fully integrated 13.56MHz Radio Frequency Identification
(RFID) Analog front end and Data Framing Reader System.
This document is designed for use by customers who are experienced with
Radio Frequency Identification Devices (RFID) and firmware development
and want to develop their own application using the TRF796x. This
reference guide should be used in conjunction with the ISO15693 standard
which specifies the standard protocol, commands and other parameters
required for communication between the transponder and the reader.
