4x Boost for NXP Radar MCU

4x Boost for NXP Radar MCU

NXP has announced a radar Power architecture microprocessor for automotive radar that offers four times more performance that its earlier MPC577X.


Called S32R27, it “will deliver the features and performance required for making safe, automated driving a reality”, said the firm, going on to claim: “This means higher accuracy and safety for applications such as collision avoidance, lane change assist, autonomous emergency braking, radar cocooning with 360° perception, or adaptive cruise control. In intelligent transport systems, vulnerable road users like pedestrians, motorcycles and bicycles can be detected and tracked much faster.”

The processor has four cores, two 240MHz 32bit e200z7 and two 120MHz 32bit e200z4, that latter of which are available in lock-step operation. These work with 2Mbyte flash and 1.5Mbyte SRAM, both with error checking. “It meets the high performance computation demands required by modern beam-forming fast chirp modulation RADAR systems by offering unique signal processing acceleration together with powerful multi-core architecture,” said NXP.

Amongst radar interfaces are four lanes of MIPI-CSI2, four 12bit 10Msample/s ΣΔ ADCs and a 10Msample/s 12bit DAC.

Then there are the general-purpose interfaces: Zipwire, two 12bit SAR ADCs, dual SPI, dual I2C, triple FlexCAN (inc 2x CAN-FD), Flexray, LINFlexD and Ethernet.

Safety qualification is to ISO26262 SEooC up to ASIL-D, and there is a CSE2 security processor.

Operation is over -40 to 150°C (Tj), with AEC-Q100 Grade 1 qualification.

S32R27 will be part of two demonstrations showcased by NXP at Electronics: Combined with its MR3003 SiGe radar transceiver at the firm’s booth in Hall A6], and combined with its TEF810x RF CMOS transceiver in its Smarter World Tour truck.
