LRI64

Signal description

9/52

Signal description

AC1, AC0

The pads for the Antenna Coil. AC1 and AC0 must be directly bonded to the antenna.

Commands

The LRI64 supports the following commands:

3.1

Inventory

Used to perform the anti-collision sequence. The LRI64 answers to the Inventory command

when all of the 64 bits of the UID have been correctly written.

3.2

Stay Quiet

Used to put the LRI64 in Quiet mode. In this mode, the LRI64 only responds to commands

in Addressed mode.

3.3

Read Block

Used to output the 8 bits of the selected block.

3.4

Write Block

Used to write a new 8-bit value in the selected block, provided that the block is not locked.

This command can be issued only once to each block.

3.5

Get_System_Info

Used to allow the application system to identify the product. It gives the LRI64 memory size,

and IC reference (IC_ID).

3.6

Initial Dialogue for Vicinity Cards

The dialogue between the Vicinity Coupling Device (VCD) and the LRI64 is conducted

according to a technique called Reader Talk First (RTF). This involves the following

sequence of operations:

activation of the LRI64 by the RF operating field of the VCD

transmission of a command by the VCD

transmission of a response by the LRI64
