Product details
Overview
FS32R294HAK0MJDR from NXP is a 32-bit dual-core Power Architecture® radar microcontroller with two 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 FS32R294HAK0MJDR datasheet, FS32R294HAK0MJDR pinout, FS32R294HAK0MJDR application, or FS32R294HAK0MJDR equivalent, key selection criteria include functional safety architecture (ASIL-D), radar-specific acceleration (SPT 2.8), memory size (5.5 MB SRAM), interface scalability (dual MIPI CSI-2), and backward compatibility with S32R274/S32R27.
Technical Context
The FS32R294HAK0MJDR implements a heterogeneous multicore architecture: two high-performance e200z7 cores handle radar application processing, while two dedicated e200z4 cores operate in lockstep for ISO 26262 ASIL-D safety monitoring. The SPT 2.8 accelerator offloads FFT, CFAR, and beamforming operations directly from CPU load.
It integrates cross-timing engine (CTE) for deterministic radar timing synchronization, supports QSPI external memory expansion, and includes cryptographic services engine with secure boot and AES/SHA/ECDSA acceleration - all within a single die optimized for low-power radar sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Cores | Dual e200z7 (application) + dual e200z4 in lockstep (safety) - enables concurrent real-time radar processing and independent fault-detection path per ISO 26262. |
| On-chip Memory | 5.5 MB SRAM - eliminates need for external RAM in mid-tier corner radar designs, reducing BOM cost and board area. |
| Radar Acceleration | Signal Processing Toolkit 2.8 (SPT 2.8) - hardware-accelerated FFT, CFAR, and beamforming with >3× throughput/W vs. pure CPU execution. |
| Interfaces | Gb Ethernet, CAN FD, FlexRay, dual MIPI CSI-2 - supports multi-sensor fusion (e.g., radar + camera) and high-bandwidth radar data streaming. |
| Safety Certification | Designed to meet ASIL-D per ISO 26262 - includes structural core self-test, lockstep monitoring, and safety-managed memory protection units. |
| Security Engine | Cryptographic Services Engine with secure boot, AES-128/256, SHA-256, ECDSA - enables secure OTA updates and trusted radar firmware execution. |
Pinout & Package
FS32R294HAK0MJDR is housed in a 256-pin LFBGA package (15 mm × 15 mm, 0.8 mm pitch) with thermal pad. Pin assignment follows NXP's S32R29x standard ballout for radar MCU family compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_CORE | Core power supply | 1.0 V ±3% supply for e200z7/z4 cores and SPT - requires low-noise regulation and local decoupling. |

| CANFD0_TX/CANFD0_RX | CAN FD transceiver interface | Supports 5 Mbps data phase for diagnostic, configuration, and status reporting in automotive domain networks. |
| CTE_TRIG_IN/CTE_TRIG_OUT | Cross Timing Engine trigger I/O | Enables precise synchronization of radar chirp timing across multiple sensors or with camera exposure signals. |
Key Features
| Feature | Design Value |
|---|---|
| Dual e200z7 + dual lockstep e200z4 cores | Enables simultaneous radar algorithm execution and real-time safety monitoring without software overhead or shared resource contention. |

| Dual MIPI CSI-2 interfaces | Allows concurrent connection to two independent radar MMICs (e.g., front + corner) or radar + camera for sensor fusion architectures. |
| Integrated CTE and timing peripherals | Provides sub-10 ns jitter timing control for FMCW chirp generation and ADC sampling alignment - critical for Doppler accuracy. |

FAQ
What is the maximum operating frequency of the FS32R294HAK0MJDR application cores?
The FS32R294HAK0MJDR features dual e200z7 cores operating up to 500 MHz. This clock speed enables real-time execution of complex radar algorithms including 2D FFT, CFAR detection, and DBF beamforming within tight timing constraints. The FS32R294HAK0MJDR achieves this performance while maintaining ASIL-D compliance through dedicated safety cores and hardware monitors.
Does the FS32R294HAK0MJDR support secure boot and cryptographic acceleration?
Yes, the FS32R294HAK0MJDR integrates a Cryptographic Services Engine supporting secure boot, AES-128/256 encryption/decryption, SHA-256 hashing, and ECDSA signature verification. These capabilities ensure authenticated firmware loading and runtime integrity checks - essential for OTA updates in automotive radar systems. The FS32R294HAK0MJDR implements these functions in dedicated hardware to avoid CPU overhead.
How does the FS32R294HAK0MJDR differ from the S32R274 in terms of memory and interfaces?
The FS32R294HAK0MJDR doubles the on-chip SRAM to 5.5 MB and adds a second MIPI CSI-2 interface compared to the S32R274's 2.5 MB and single CSI-2. It also upgrades from SPT 2.4 to SPT 2.8 and increases core clock frequency to 500 MHz. These enhancements make the FS32R294HAK0MJDR suitable for higher-channel-count radar sensors with multi-front-end support.
Is the FS32R294HAK0MJDR pin-compatible with other S32R29x variants?
Yes, the FS32R294HAK0MJDR shares the same 256-pin LFBGA package and pinout with other S32R29x family members such as FS32R292 and FS32R296. This allows hardware reuse across performance tiers - for example, upgrading from FS32R292 to FS32R294HAK0MJDR requires only firmware and configuration changes, not PCB redesign.
What radar front-ends are officially supported with the FS32R294HAK0MJDR?
The FS32R294HAK0MJDR is validated with NXP's TEF82xx and TEF81xx radar transceivers via MIPI CSI-2 and SPI interfaces. The Radar SDK for S32R29x provides drivers and reference examples for TEF8202, TEF8204, and TEF8102 integration. The FS32R294HAK0MJDR's dual MIPI CSI-2 lanes enable simultaneous connection to two TEF82xx devices for MIMO radar configurations.
