DESCRIPTION
• Encoding options:
This device is a Radio Frequency Identification (RFID)
tag that provides a bidirectional interface for program-
ming and reading the contents of the user array. The
device is powered by an external RF transmitter
through inductive coupling. When in read mode, the
device transmits the contents of its memory array by
damping (modulating) the incoming RF signal. The
reader is able to detect the damping and decodes the
data being transmitted. Code length, modulation
option, encoding option, and bit rate are set at the
factory to fit the needs of particular applications.

• Modulation options:
- Direct, FSK, PSK (change on data change),
PSK (change at the beginning of a one)
APPLICATION
RF
Signal
Transmitter/
Receiver
The user memory array of this device can be
programmed contactlessly after encapsulation. This
allows the user to keep encapsulated blank tags in
stock for on-demand personalization. The tags can
then be programmed with data as they are needed.

Data
These devices are available in die, wafer, PDIP, SOIC,
and COB module form. The encoding, modulation,
frequency, and bit rate options are specified by the
customer and programmed by Microchip Technology
Inc. prior to shipment. Array programming and
serialization (SQTP) can also be arranged upon
request. See TB023 (page 23) for more information.
