SAMES KEY RING TAG

GENERAL SPECIFICATION

The SAMES key ring tag provides the secure and convenient

link for access control, customer loyalty, personnel

identification, etc. It includes the SAMES SA7110 IC and

antenna circuit and has been packaged to withstand rough

handling associated with key ring use.

The SAMES key ring tag is available asa read only version with

a unique factory programmed identification code.

MEMORYARRAY

The SA7110 IC used in the key ring tag contains 64 bits divided

in to five groups of information.9 bits are used for the header, 10

row parity bits (P0-P9),4 column parity bits (PC0-PC3), 40 data

bits (D00-D93) and1 stop bit set to logic 0.

The header is composed of the9 bits which are all programmed

to “1”. The header is followed by 10 groups of4 data bits and1

row parity bit. The 10 groups of4 data bits allow for 100 billion

combinations. The last group consists of4 column parity bits

with1 stop bit which is programmed to “0”.

Bits D00 to D03 and bits D10 to D13 are customer specific

identification.

The 64 bits are outputted serially in order to control the

modulator. The output sequence is repeated continuously as

long as the tag is in the reader RF field.
