Product details
Overview
S32M244LCABWKHST from NXP Semiconductors is an automotive-grade System-in-Package (SiP) microcontroller integrating an Arm Cortex-M4F core @ 80 MHz, 512 kB flash, 64 kB SRAM, and a 6-channel MOSFET gate driver unit for BLDC/PMSM motor control. It operates directly from a 12 V car battery (3.5–40 V VSUP), includes integrated LIN/CXPI/CAN FD physical layer, 5 V/30 mA regulator for external sensors, and meets ISO 26262 ASIL-B for single-motor drive applications in powertrain and chassis systems.
For engineers reviewing the S32M244LCABWKHST datasheet, S32M244LCABWKHST pinout, S32M244LCABWKHST application, or S32M244LCABWKHST equivalent, this page delivers verified technical context, validated package mapping (64-pin LQFP-EP), confirmed functional parameters including ASIL-B compliance, 512 kB flash, 6-channel GDU, and real-world motor control use cases - all extracted from NXP's official S32M2xx Rev. 10 datasheet and ordering documentation.
Technical Context
The S32M244LCABWKHST implements a tightly coupled SiP architecture combining MCU and Application Extension (AE) subsystems: the Arm Cortex-M4F core handles real-time motor control algorithms and communication stacks, while the AE block integrates high-voltage analog functions - including HVI battery monitoring, DPGA current sensing, LIN/CXPI/CAN FD PHY, and six-channel gate driver with bootstrap charge pump and HD overvoltage protection logic.
Its dual-domain power management supports direct 12 V battery input with internal regulation to 3.3 V/5 V for MCU and peripherals, plus dedicated VLS_OUT supply for gate drivers. The device uses PTA5 and RESET_B as mandatory board-level connections and supports external p-channel FET regulation via GCTL to manage thermal dissipation under high ambient conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32M243LCABWKHST | Same core, package, and GDU; reduced 256 kB flash and 32 kB SRAM - no D-flash partitioning. | Targeted at cost-sensitive single-motor applications with simpler control firmware and no OTA update requirement. | Select when firmware size < 200 kB and safety diagnostics fit within smaller RAM; retains identical pinout and thermal profile. |
| S32M274LCABWKHST | Arm Cortex-M7F @ 120 MHz, 512 kB flash, 112 kB SRAM, HSE-B security, and EMIOS-based timer architecture. | Designed for multi-motor or high-dynamic-response applications requiring higher compute throughput and advanced crypto acceleration. | Choose for complex vector control with dual-axis FOC or when AUTOSAR Adaptive support is needed; not pin-compatible due to different peripheral mapping. |
Compared with S32M243LCABWKHST, the S32M244LCABWKHST offers double the SRAM for larger control buffers and diagnostics, while S32M274LCABWKHST delivers higher CPU performance but requires PCB redesign and software re-architecture due to M7 core and EMIOS timer differences.

FAQ
What is the operating temperature grade for S32M244LCABWKHST?
The S32M244LCABWKHST is rated for Grade W operation: −40 °C to +150 °C ambient temperature. This enables deployment in under-hood applications such as electronic throttle bodies and HVAC blowers where high thermal stress is expected. The device maintains ASIL-B compliance across this full range, and its thermal design requires proper PCB copper pour on the exposed pad per NXP AN5032 guidelines.
Does S32M244LCABWKHST include an integrated CAN FD transceiver?
Yes, the S32M244LCABWKHST integrates a full CAN FD physical layer (PHY) - not just a controller. Pins CAN0_TX and CAN0_RX connect directly to the bus with only external 120 Ω termination required. This eliminates the need for an external CAN FD transceiver IC, reducing BOM cost and PCB area while maintaining compliance with ISO 11898-2:2016.
How does the gate driver unit in S32M244LCABWKHST support 3-phase BLDC control?
The S32M244LCABWKHST features a 6-channel MOSFET pre-driver (GDU) with three high-side (HG0–HG2) and three low-side (LG0–LG2) outputs, internally routed from FlexTimer modules. It supports bootstrap gate driving via VBSx pins and includes HD overvoltage protection that disables outputs if VSUP exceeds safe thresholds - enabling robust, self-protected 3-phase inverter control without external driver ICs.
What is the purpose of the GCTL pin on S32M244LCABWKHST?
The GCTL pin on S32M244LCABWKHST controls an external p-channel power FET used to regulate the VPRE pre-regulation stage. This reduces on-die power dissipation during high ambient temperature operation (e.g., under-hood), ensuring the maximum junction temperature is not exceeded. The FET gate is driven directly by GCTL, and its use is optional but recommended for Grade W applications above 105 °C ambient.
Is S32M244LCABWKHST pin-compatible with other S32M24x variants?
Yes, all S32M24x devices - including S32M241, S32M242, S32M243, and S32M244 - share identical 64-pin LQFP-EP packaging and pinout. This allows hardware reuse across variants; firmware and BOM can be scaled based on memory (128–512 kB flash) and feature requirements without layout changes.
