TI’s New Radar Sensors for Autonomous Driving
17 May, 2017
With its Its 76GHz-81GHz FMCW radar in a single-chip, Texas Instruments targets hyper sensing emerging markets such as Autonomous Driving, Industrial Robotics, Homeland Security and Medical Devices

Texas Instruments Inc. (TI) unveiled what it says is the world’s most precise single-chip millimeter wave sensor: It is a 76GHz-81GHz Frequency Modulated Continuous Wave (FMCW) radar in a single-chip that can measure distances lower than the width of a single strand of human hair. With this product, TI targets hyper sensing emerging markets such as Autonomous Driving, Industrial Robotics and Control, Homeland Security, Medical Devices and more.

TI’s new millimeter wave (mmWave) single-chip CMOS sensors includes five solutions across two families of sensors with a complete end-to-end development platform (SDK). Available for sampling today, the AWR1x and IWR1x families combines analog and RF circuitry with digital signal processing to enable the implementation intelligent sensing solutions.
The designers can choose a sensor with MCU, a sensor with DSP, or a sensor with MCU and DSP all together in a single chip.
Looking Through Walls
The sensing capabilities options can reach less than a 4-centimeter range resolution with accuracy down to less than 50 micrometers, and lower precision with multitude ranges up to 300 meters. IWR1x and AWR1x mmWave sensors can sense through plastic, dry wall, clothing, glass and many other materials, and through environmental conditions such as lighting, rain, dust, fog or frost. They are adapted to Automotive industry demands, including ISO 26262 approval which enables Automotive safety integrity level (ASIL)-B.
The AWR/IWR sensors portfolio is a self-contained FMCW transceiver single-chip solution in the band of 76-81GHz With 4GHz available bandwidth. It is built on TI’s low-power 45-nm RFCMOS process. Simple programming model changes can enable a wide variety of sensor implementation (Short, Mid, Long) with the possibility of dynamic reconfiguration for implementing a multimode sensor. It consists of 4 Receive Channels and 3 Three Transmit Channels (Two Can be Used Simultaneously).
Specially Designed CMOS Transistor
“The portfolio scales from a high performance front-end to a single chip integrating RF, microcontroller, DSP and Interfaces in the same die, and addresses two key markets: We believe they will create a significant impact on both these markets by making sensors more accurate, smaller and simpler.”
The sensors are available today and appears in a BGA Package and a new mmWave software development kit (SDK) includes sample algorithms and software libraries which simplify RF designs through less than 20 simple application programming interfaces (APIs). By leveraging TI estimates that with its mmWave SDK platform engineers can start developing their applications in less than 30 minutes.
