Datasheet

A radar microcontroller from NXP Semiconductors has been engineered to meet the high-performance computation demands required by modern beam-forming and fast chirp-modulation radar systems. The S32R274 which is available from Mouser Electronics combines signal-processing acceleration with a multicore architecture to provide up to four times the power performance in industrial and automotive applications, compared to previous generations of products.

The microcontroller offers a multifaceted solution for general software tasks and car bus interfacing. Combined with radio frequency (RF) front-end technologies (RFCMOS or BiCMOS), it provides designers a scalable solution that addresses ultra-short-range, short-range, mid-range and long-range radar systems.

Four Power Architecture cores including an e200Z4 32-bit CPU for its safety core, and e200Z7 32-bit CPUs for its dual computation cores provide exceptional power performance, integration, safety, and reliability.

Other features include 2MBytes of flash with ECC, 1.5MBytes of SRAM with ECC, and a Signal Processing Toolbox (SPT) for radar signal processing acceleration.

For memory protection, the S32R274 provides 24 entries for each core memory protection unit, a data and instruction bus system memory protection unit, and register protection.

Security features include a Cryptographic Security Engine for advanced security management, a Password and Device Security module that supports censorship and life-cycle management, and a diary control for tamper detection.

With support for ISO 26262 SEooC up to ASIL-D classification and a rating for AEC-Q100 Grade 1, the S32R274 is an ideal solution for Advanced driver assistance systems (ADAS).

The S32R274 is supported by the S32R274RRUEVB evaluation board, also available from Mouser, which offers a variety of interfaces, including RS232/SCI, FlexRAY, LINFlexD, Ethernet, and two CAN interfaces.
