DESCRIPTION
The Texas Instruments’ low-frequency (LF) reader provides all the functionality required to communicate with
Texas Instruments 134.2 kHz LF transponders which are available in a variety of form factors. The RI-STU-251B
Reader/Writer is capable driving a variety of antennas with inductance ranges from 26.0µH to 27.9µH including
TI standard antennas RI-ANT-G01E, RI-ANT-G02E, RI-ANT-G04E gate antennas as well as RI-ANT-S01C and
RI-ANT-S02C stick antennas. The RI-STU-251B includes an automatic antenna resonance tuning feature which
further reduces the need for maintenance and simplifies installation. It also supports both RS232 and RS422/485
interface standards.
The RI-STU-251B is well suited for usage in a broad range of applications including, but not limited to, access
control, vehicle identification, container tracking, asset management and waste management applications.
The Series 2000 Reader S251B provides all RF and Control Functions to communicate with 134.2 kHz
HDX/FSK transponders. It sends an energizing signal to the transponder, modulates the RF signal to send data
to the transponder, decodes and checks the received transponder data and transmits it via a standard serial
interface (RS232, RS422/485). The reader includes a Dynamic Auto Tuning (DAT) function that automatically
tunes a standard antenna to resonance and keeps it tuned during operation.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
