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 are factory programmed
during production.
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 DV103002 Developer’s Kit includes Contactless
Programmer, MCRF250 Anti-Collision FSK reference
reader, and reference design guide. The reference
design guide includes schematics for readers and
contactless
programmer
documentation for antenna circuit designs.
