Product details
Overview
S32K314EHT1VMMST from NXP Semiconductors is an ASIL-B qualified, single-core Arm Cortex-M7 microcontroller designed for automotive body control, gateway, and chassis applications. It operates from 2.97 V to 5.5 V across –40 °C to 125 °C, integrates 4 MB program flash with ECC, 512 KB SRAM with ECC (including 192 KB TCM), and supports CAN FD, Ethernet AVB/TSN, and QuadSPI up to 480 Mbps.
For engineers reviewing the S32K314EHT1VMMST datasheet, S32K314EHT1VMMST pinout, S32K314EHT1VMMST application, or S32K314EHT1VMMST equivalent, key selection criteria include its 160 MHz Cortex-M7 core with FPU/DSP, triple 12-bit ADCs (24-channel each), lockstep-capable safety architecture, and MAPBGA437 package with 320 GPIO pins and 60 wakeup-capable I/Os.
Technical Context
The S32K314EHT1VMMST implements a single Arm Cortex-M7 core running at up to 160 MHz with integrated Single Precision FPU, DSP extensions, and configurable NVIC. Its memory subsystem includes 4 MB on-chip flash with ECC, 512 KB SRAM with ECC (192 KB tightly coupled), and instruction/data caches to minimize latency in real-time control loops.
Timing and communication are managed via three eMIOS modules (72 timer channels), six LPSPI, two LPI2C, sixteen LPUART, six FlexCAN (all with CAN FD), two SAI, and one 100 Mbps Ethernet module with AVB/TSN support - all coordinated through a 64-bit crossbar fabric and DMAMUX-controlled 32-channel DMA.

Use Scenario: Centralized control of lighting, door locks, window lifts, and seat position in mid-tier vehicles. IC Role / Device Role / Timing Role: Main application MCU executing ASIL-B-compliant control logic, managing LIN clusters via 16 LPUARTs, and coordinating CAN FD messages across powertrain and chassis domains. Use Value: 4 MB flash enables feature-rich software stacks; 60 wakeup-capable pins allow selective subsystem activation without full ECU wake - reducing parasitic drain. |
Use Scenario: Protocol translation and firewall between high-speed CAN FD/Ethernet domains and low-speed LIN/UART sensor networks. IC Role / Device Role / Timing Role: Domain gateway processor routing time-sensitive ADAS data over Ethernet AVB/TSN while filtering non-critical diagnostics via FlexCAN message objects. Use Value: Dual-bus isolation via XRDC and VIRT_WRAPPER prevents cross-domain interference; QuadSPI supports external secure boot image storage. |
| Electric Power Steering (EPS) Support | Chassis Domain Controller |
|
Use Scenario: Sensor preprocessing and torque assist coordination in entry-level EPS systems requiring functional safety but no lockstep redundancy. IC Role / Device Role / Timing Role: Real-time motor control unit using eMIOS PWM channels, BCTU-triggered ADC sampling, and FPU-accelerated PID calculations at 160 MHz. Use Value: 192 KB TCM ensures zero-cycle memory access for control loop buffers; ECC-protected SRAM prevents silent data corruption in torque command paths. |
Use Scenario: Integration of brake-by-wire, suspension damping, and active roll control functions into a single ECU. IC Role / Device Role / Timing Role: High-integrity timing hub synchronizing 3× eMIOS timer banks, RTC API interrupts, and STM modules across distributed actuators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K324EHT1VMMST | Dual-core Cortex-M7 @ 160 MHz, 4 MB flash, 512 KB SRAM, same package - adds parallel processing capability and enhanced DMA bandwidth. | Required for applications needing split control/safety partitioning or higher throughput in sensor fusion pipelines. | Select when workload exceeds single-core capacity or ASIL-D decomposition mandates dual-core lockstep (requires S32K344 instead). |
| S32K344EHT1VMMST | Lockstep dual Cortex-M7 cores @ 160 MHz, ASIL-D certified, identical memory and peripheral set - includes redundant execution and fault containment. | Mandatory for steering angle control, brake actuation, or other ASIL-D functions where single-point failure must be eliminated. | Choose only if ISO 26262 ASIL-D compliance is contractually required - increases BOM cost and software certification effort. |

FAQ
What is the maximum operating frequency of the S32K314EHT1VMMST?
The S32K314EHT1VMMST features a single Arm Cortex-M7 core rated for up to 160 MHz operation. This frequency is achievable across its full –40 °C to +125 °C ambient temperature range and 2.97 V–5.5 V supply voltage, with performance sustained by zero-wait-state I/D-TCM and integrated FPU/DSP units. The S32K314EHT1VMMST does not support overclocking beyond this specification.
Does the S32K314EHT1VMMST support CAN FD, and how many channels are available?
Yes, the S32K314EHT1VMMST integrates six FlexCAN modules, all supporting CAN FD protocol with bit rates up to 5 Mbps. Each channel includes message objects, FIFOs, and error counters compliant with ISO 11898-1:2015, enabling high-bandwidth communication in modern automotive networks without requiring external CAN FD controllers.
What package type and pin count does the S32K314EHT1VMMST use?
The S32K314EHT1VMMST is offered exclusively in the MAPBGA437 package: a 17 mm × 17 mm ball grid array with 437 solder balls, 0.8 mm pitch, and an exposed thermal pad. It provides 320 GPIO pins, of which 60 support wakeup functionality and 32 support configurable interrupts - matching the pinout of other S32K3xx devices in the same package variant.
Is the S32K314EHT1VMMST qualified for automotive safety standards?
Yes, the S32K314EHT1VMMST is ASIL-B compliant per ISO 26262, with integrated safety mechanisms including ECC on all memories, CRC modules, dual SWT timers, FCCU fault collection, and centralized error detection. It does not meet ASIL-D requirements - those require the lockstep-based S32K344EHT1VMMST variant.
What debug interfaces are supported by the S32K314EHT1VMMST?
The S32K314EHT1VMMST supports Serial Wire Debug (SWD) and JTAG via dedicated pins, with full CoreSight trace capabilities including SWO, ITM, DWT, HTM, and ETB. It enables real-time instruction tracing, data watchpoints, and Flash Patch and Breakpoint (FPB) functionality - all accessible through standard ARM-compatible debug probes without additional hardware adapters.
