Block Diagram
The configuration register includes options for commu-
nication protocol (ASK, FSK, PSK), data encoding
method, data rate, and data length.These options are
specified by customer and factory programmed during
assembly. Because of its many choices of configuration
options, the device can be easily used as an alternative
or second source for most of the existing low frequency
passive RFID devices available today.
The device has a modulation transistor between the
two antenna connections (V
A
and V
B
). The modulation
transistor damps or undamps the coil voltage when it
sends data. The variation of coil voltage controlled by
the modulation transistor results in a perturbation of
voltage in reader antenna coil. By monitoring the
changes in reader coil voltage, the data transmitted
from the device can be reconstructed.
The device is available in die, wafer, Chip-on-Board
(COB) modules, PDIP, or SOIC packages. Factory
programming and memory serialization (SQTP) are
also available upon request. See TB023 for more
information on contact programming support.
The DV103001 developer’s kit includes Contactless
Programmer, ASK, FSK, PSK reference readers, and
reference design guide. The reference design guide
includes schematics for readers and contactless
programmer as well as in-depth document for antenna
circuit designs.
