Description
NOTE
This document is an abbreviated version of the full TRF4140-Q1 data sheet. For access to
the full data sheet, silicon errata, application report, and other support collateral, complete
the request form.
The TRF4140-Q1 low-frequency (LF) transceiver base station device is intended for immobilizer and
PEPS systems to communicate with LF transponders, remote keyless entry, and passive entry devices.
The antenna driver stage consists of four MOSFET antenna drivers to send modulated LF transmissions
and a receiver for detection and demodulation of LF transponder responses. The HDX communication
scheme uses frequency shift keying (FSK) as the uplink modulation. The device can drive LF antennas to
provide a wake-up and data sequence (PEPS), and it can also receive transponder responses on any or
all channels (immobilizer).
The TRF4140-Q1 device needs VDD supply (5 V) for its control blocks and to feed the integrated logic
voltage regulator. The antenna driver is supplied separately by VDDH (4 V to 20 V). This voltage can be
used to generate a sine-wave output signal for superior EMC performance, which is important for remote
antenna applications with several meters of antenna cable.
The TRF4140-Q1 device manages all timings required for a communication sequence without the need for
an accurate host controller interaction. In conjunction with transmit and receive FIFOs, the host controller
is off-loaded from all timing-critical events, which enables easy host controller process scheduling. In
particular, the host controller start-up process for an automotive body control module is tremendously
relaxed by this base station device.
The TRF4140-Q1 device supports sequence preloading and sequence execution on external events to
start the immobilization process exactly when the key fob is detected. So, delays due to configuration can
be avoided in inconvenient time frames.

Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
