Freescale MCU, radar transceiver chipset

Freescale Semiconductor has announced that it now offers a comprehensive system-level solution for automotive radar-based advanced driver assistance systems (ADAS).

The Qorivva MPC577xK microcontroller (MCU) and MRD2001 77GHz radar transceiver chipset provide the embedded technology necessary for affordable radar based ADAS solutions with fewer components.

Using Freescale's Qorivva MPC577xK MCU and MRD2001 77GHz radar transceiver chipset, automakers can implement long-range and mid-range frontal radar for adaptive cruise control and autonomous emergency braking systems, as well as manage blind spot and side-impact detection – all through a single, scalable, multi-channel solution.

Designers can pair the radar transceiver chipset with the Qorivva MCU to achieve a total system solution for both low-end and high-end radar modules. By utilising a single, scalable solution, automakers can avoid purchasing and reconfiguring various solutions across vehicle models, saving time and material costs.

In addition to ADAS, Freescale's Qorivva MPC577xK MCU and MRD2001 77GHz radar transceiver chipset solution are applicable for a broad range of industrial and emerging consumer applications, such as gesture sensing, safety curtains, security systems and location positioning.

Qorivva MPC577xK MCU

The Qorivva MPC577xK MCU, built on Power Architecture technology, provides the highest level of digital and analogue integration in a single-chip solution for radar applications, removing up to four additional major printed circuit board (PCB) components and reducing system-level cost, PCB space and software complexity. The MCU also provides high performance for intense computational tasks with key integrated digital accelerators and features a state-of-the-art signal processing tool-box that contains all of the hardware modules required for processing sampled signals from short-, medium- and long-range radar applications. These features of the Qorivva MPC577xK MCU will help enable adoption of radar-based ADAS in more mainstream vehicles.

MRD2001 77GHz radar transceiver chipset

The MRD2001 77GHz radar transceiver chipset provides a comprehensive, high-performance radar transceiver featuring low power consumption and exceptional VCO phase noise, enabling precise discrimination of objects. The chipset supports fast modulation with simultaneous active channels, enabling excellent spatial resolution and detection accuracy. The MRD2001 is housed in advanced packaging technology that provides extremely low insertion loss and parasitics at frequencies up to 100GHz. The packaged chipset simplifies the end user's assembly of the radar module since there is no need for chip and wire assembly techniques for bare die. Furthermore, the chipset is readily scalable up to four TX channels and 12 RX channels, enabling a single radar platform capable of electronic beam steering across a wide field of view to support long-range, mid-range and short-range radar applications over the full range of budget to luxury vehicles.

Availability and pricing

Freescale's Qorivva MPC577xK MCU and MRD2001 77GHz radar transceiver chipset are now available in sample quantities. For more information, contact your local Freescale sales representative.
