Product details
Overview
FS32R294HFK0MJDT from NXP is a 32-bit Power Architecture® multicore radar microcontroller featuring dual e200z7 application CPUs, dual lockstep e200z4 safety cores, Signal Processing Toolkit 2.8 (SPT 2.8), 5.5 MB on-chip SRAM, and support for Gb Ethernet, CAN FD, FlexRay, and dual MIPI CSI-2 interfaces - deployed in automotive corner radar sensor systems requiring ASIL D compliance.
For engineers reviewing the FS32R294HFK0MJDT datasheet, FS32R294HFK0MJDT pinout, FS32R294HFK0MJDT application, or FS32R294HFK0MJDT equivalent, key selection considerations include ASIL D functional safety certification, SPT-accelerated radar signal processing throughput, dual MIPI CSI-2 interface count, 5.5 MB integrated SRAM capacity, and compatibility with TEF82xx/TEF81xx RF front ends.
Technical Context
The FS32R294HFK0MJDT implements a heterogeneous multicore architecture: two high-performance e200z7 cores handle application-layer radar algorithms, while two dedicated e200z4 cores operate in lockstep mode for ISO 26262 ASIL D safety monitoring. The SPT 2.8 accelerator executes FFT, CFAR, and beamforming operations directly in hardware, offloading CPU cycles and reducing power per radar frame.
It integrates cross-timing engine (CTE) for deterministic synchronization across radar signal chain components, supports QSPI external memory expansion, and includes cryptographic services engine with secure boot, AES-128/256, SHA-256, and TRNG - all validated for automotive safety-critical radar processing.
Key Specifications

FAQ
What is the maximum operating frequency of the e200z7 cores in FS32R294HFK0MJDT?
The e200z7 application cores in FS32R294HFK0MJDT operate at up to 600 MHz, doubling the clock frequency of the S32R274. This enables higher radar frame rates and more complex signal processing per unit time. The FS32R294HFK0MJDT uses this increased clock speed to sustain real-time FFT and CFAR execution across dual MIPI CSI-2 data streams without external memory bottlenecks.
Does FS32R294HFK0MJDT support AUTOSAR-compliant radar drivers?
Yes, FS32R294HFK0MJDT is supported by NXP's AUTOSAR Safety MCAL suite, including drivers for CAN FD, Ethernet, ADC, and SPT interfaces. These drivers are qualified for ASIL D development and integrate directly into AUTOSAR 4.3+ toolchains. The FS32R294HFK0MJDT also supports non-AUTOSAR MCAL for legacy or model-based radar stacks.
How does FS32R294HFK0MJDT achieve ASIL D compliance?
FS32R294HFK0MJDT achieves ASIL D readiness through dual lockstep e200z4 safety cores, structural core self-test, ECC-protected SRAM and buses, memory BIST, and hardware-assisted safety monitors for clock, voltage, and temperature. All safety mechanisms are documented in the FS32R294HFK0MJDT Functional Safety Manual (UM11125) and certified per ISO 26262-2:2018.
What radar front-end ICs are officially supported with FS32R294HFK0MJDT?
NXP officially supports TEF82xx and TEF81xx 77 GHz radar transceivers with FS32R294HFK0MJDT via the Radar SDK and reference schematics. The FS32R294HFK0MJDT MIPI CSI-2 interfaces are electrically and protocol-verified for direct connection to TEF8202/TEF8204 outputs, enabling zero-latency radar data ingestion without FPGA bridging.
Is FS32R294HFK0MJDT pin-compatible with earlier S32R devices like S32R274?
No, FS32R294HFK0MJDT is not pin-compatible with S32R274 due to additional MIPI CSI-2, Ethernet, and safety monitoring pins - it uses a revised 256-pin LFBGA footprint. However, the FS32R294HFK0MJDT maintains software compatibility with S32R274 via the S32DS IDE and Radar SDK, allowing reuse of core radar algorithms and safety libraries.
