Product details
Overview
S32M276LHABMKHST from NXP Semiconductors is an automotive-grade System-in-Package (SiP) microcontroller integrating an Arm Cortex-M7F core @ 120 MHz, 1 MB program flash, 128 kB SRAM (including 96 kB TCM), dual EMIOS timers, two CAN-FD physical interfaces, and a 6-channel MOSFET gate driver unit for 3-phase BLDC/PMSM motor control. It operates directly from a 12 V car battery (3.5–40 V VSUP range), includes integrated 5 V/30 mA supply for Hall sensors, and supports LIN/CXPI/CAN-FD bus communication without external PHY.
For engineers reviewing the S32M276LHABMKHST datasheet, S32M276LHABMKHST pinout, S32M276LHABMKHST application, or S32M276LHABMKHST equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world motor control use cases, and validated alternative parts - all aligned to Rev. 10 (25 Feb 2026) S32M2xx data sheet and ordering information.
Technical Context
The S32M276LHABMKHST implements a dual-domain SiP architecture: the MCU domain hosts the Arm Cortex-M7F core with TCM-backed SRAM, while the Application Extension (AE) domain integrates high-voltage analog functions including a 6-channel GDU, DPGA current-sense amplifier, HVI/VM battery monitoring, and LIN/CXPI/CAN-FD PHYs. All three CAN-FD modules are available on LIN variants; on CAN variants, CAN0 and CAN1 connect to internal CAN-FD PHYs.
It features two EMIOS timer units (CAN variant: 15+5 channels; LIN variant: 16+6 channels), one BCTU for ADC triggering, two 15-bit ADCs with six internally routed channels for DPGA output, DC-link voltage, phase voltages, and HVM inputs, and hardware security via HSE-B engine compliant with ISO 26262 ASIL-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Core & Frequency | Arm Cortex-M7F @ 120 MHz - enables real-time field-oriented control (FOC) loop execution within sub-μs latency. |
| Memory | 1 MB flash / 128 kB SRAM (96 kB TCM) - supports AUTOSAR MCAL, complex motor algorithms, and secure boot firmware. |
| Motor Drive Interface | 6-channel GDU with HS/LS outputs - drives external N-channel MOSFETs in 3-phase inverter topology without external pre-drivers. |
| Communication | 2× CAN-FD + 3× LPUART + 1× LPSPI + 1× LPI2C - enables multi-node vehicle network integration and diagnostic over CAN or LIN. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32M274LHABMKHST | 512 kB flash, 112 kB SRAM (96 kB TCM), same GDU/ADC/CAN-FD features. | Lower memory capacity limits complex AUTOSAR stack or dual-motor control firmware. | Select when application firmware size ≤ 450 kB and TCM usage < 90 kB. |
| S32K344UJT1VLQY | Arm Cortex-M7 @ 200 MHz, 2 MB flash, no integrated GDU or HV analog front-end - requires external gate drivers and regulators. | Requires additional HV power management ICs and MOSFET drivers - increases layout complexity and failure points. | Select when higher CPU performance is prioritized over integration, and board space allows discrete HV components. |
Compared with S32M276LHABMKHST, S32M274LHABMKHST offers identical peripheral integration but reduced memory headroom, while S32K344UJT1VLQY trades SiP-level integration for raw compute throughput - making S32M276LHABMKHST optimal for compact, safety-certified, single-motor drive systems where BOM reduction and thermal efficiency are critical.

FAQ
What is the maximum operating junction temperature for S32M276LHABMKHST?
The S32M276LHABMKHST is rated for ambient temperatures from -40 °C to +125 °C (M-grade). Its maximum junction temperature is 150 °C, validated under worst-case power dissipation and airflow conditions per JEDEC JESD51 standards. Thermal design must ensure TJ remains below this limit using the exposed pad and appropriate PCB copper area.
Does S32M276LHABMKHST support CAN FD with data rates above 2 Mbps?
Yes, S32M276LHABMKHST supports CAN FD with bit rates up to 5 Mbps in the data phase, as confirmed in the S32M2xx Reference Manual section 9.3.2. The internal CAN-FD PHY complies with ISO 11898-2:2016 and supports flexible data-length coding up to 64 bytes per frame.
Can S32M276LHABMKHST drive both N-channel and P-channel high-side MOSFETs?
S32M276LHABMKHST's GDU is designed exclusively for N-channel high-side MOSFETs using bootstrap gate drive. It does not support direct P-channel high-side drive. The HGx pins output 0–12 V referenced to HSx, requiring external bootstrap capacitors and diodes for proper high-side switching.
Is the 5 V output on S32M276LHABMKHST adjustable or fixed?
The 5 V output (VLS_OUT) on S32M276LHABMKHST is fixed at 5.0 V ±3%, delivering up to 30 mA. It is generated by an internal LDO regulator and intended for powering Hall-effect sensors or small logic devices - no external feedback or adjustment is supported.
How is functional safety compliance implemented in S32M276LHABMKHST?
S32M276LHABMKHST achieves ISO 26262 ASIL-B compliance through hardware redundancy (dual-lockstep monitor for critical peripherals), HSE-B security engine for secure boot and runtime integrity checks, built-in self-test (BIST) for flash/SRAM, and safety manual documentation aligned to ISO 26262-5:2018. All safety mechanisms are validated per NXP's S32M2xx Safety Manual Rev. 4.0.
