Typical Characteristics
The performance of AT88RF1354 is dependent on the reader circuit, the loop antenna design, the board layout, the
specifications of the passive components, the quality of the supply voltages, the quality of the ground, the electrical
noise in the system, and how the reader circuit is connected to the other system components. The specifications that
are affected by these factors are included in this section as typical characteristics since they cannot be guaranteed in
all situations.
It is recommended that AT88RF1354 be used exactly as described in the reference designs in the AT88RF1354
Application Notes. Each reference design has been optimized for reliable, robust communications with cards and tags
with antenna dimensions within a specified size range. The reference designs described in the AT88RF1354
Application Notes include schematics, board designs, and a complete bill of materials. Gerber files of the PCB layout
are available.
Atmel does not provide applications engineering support for customer implementations that deviate from the reference
designs; it is strongly recommended that the AT88RF1354 reference designs be implemented exactly as provided. Any
modification to the board layout or deviation from the bill of materials will impact both electrical performance and
radiated emissions.
