Product details
Overview
S32M244LCABWKHSR 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 features integrated 12 V regulator, 5 V/30 mA auxiliary supply, CAN FD physical layer, ASIL-B compliance, and operates from -40°C to 150°C. Used in single-motor traction inverters and HVAC blower drives.
For engineers reviewing the S32M244LCABWKHSR datasheet, S32M244LCABWKHSR pinout, S32M244LCABWKHSR application, or S32M244LCABWKHSR equivalent, key selection criteria include its integrated GDU with high-side/low-side pre-driver capability, automotive temperature grade W (-40°C to 150°C), on-chip LIN/CXPI/CAN FD PHY support, and functional safety compliance per ISO 26262 ASIL-B.
Technical Context
The S32M244LCABWKHSR implements a dual-domain architecture: MCU subsystem (Cortex-M4F, flash/SRAM, peripherals) and Application Extension (AE) subsystem (gate drivers, regulators, analog monitoring). The AE domain integrates six independent half-bridge pre-drivers with bootstrap charge pump, high-voltage input (HVI) and voltage monitor (VM) circuits, and DPGA-based current sensing - all operating directly from 12 V battery supply.
Its communication stack includes one CAN FD controller with integrated PHY, configurable LPUART/LIN/CXPI interface, two LPSPI modules, and one LPI2C module. All digital I/Os are 5 V tolerant with programmable pull-ups/pull-downs and slew-rate control, and the device supports SWD/JTAG debug with trace capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F @ 80 MHz - delivers deterministic real-time motor control with FPU for field-oriented control (FOC) math. |
| Memory | 512 kB flash / 64 kB SRAM - sufficient for AUTOSAR MCAL, safety libraries, and complex motor algorithms with runtime calibration. |
| Operating Temp | -40°C to +150°C (Grade W) - qualified for under-hood motor control applications without external heatsinking. |
| GDU Channels | 6-channel MOSFET pre-driver - supports three-phase BLDC/PMSM drive with independent high-side/low-side control and shoot-through protection logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32M243LCABWKHSR | Same package, core, and GDU; 256 kB flash / 32 kB SRAM; Grade 0 (-40°C to +125°C) | Lower memory and temperature rating; suitable for cost-sensitive HVAC or seat fans without extended thermal requirements | Select when full 512 kB flash and Grade W operation are not required; reduces BOM cost without changing layout. |
| MC9S12VR64CPV | Legacy S12VR 16-bit MCU; no integrated GDU; requires external gate drivers and transceivers; no ASIL-B support | Used in legacy designs with simpler scalar control; lacks modern safety and integration features | Only for brownfield redesigns where software reuse outweighs safety and integration benefits of S32M244LCABWKHSR. |

Does the S32M244LCABWKHSR include an integrated CAN FD transceiver?
Yes, the S32M244LCABWKHSR integrates a CAN FD physical layer (PHY) - not just a controller. The CAN0_TX and CAN0_RX pins connect directly to the CAN bus without requiring an external transceiver, reducing BOM count and PCB footprint while maintaining full 5 Mbps CAN FD compliance.
How does the GDU in the S32M244LCABWKHSR support three-phase motor control?
The S32M244LCABWKHSR's GDU provides six independent pre-driver channels (HG0/LG0 through HG2/LG2) configured as three half-bridges. Each pair drives one motor phase with shoot-through prevention, bootstrap charging control, and fault reporting - enabling direct interface to external 600 V MOSFETs or IGBTs in BLDC/PMSM inverters.
What power supply configurations are supported by the S32M244LCABWKHSR?
The S32M244LCABWKHSR accepts a single 12 V battery input (VSUP: 3.5–40 V) and internally generates VDD_AE10 (3.3 V or 5.0 V), VLS_OUT (12 V for gate drivers), and VCP (charge pump voltage). It also provides a dedicated 5 V/30 mA output (VLS_OUT) for external Hall sensors, eliminating need for discrete LDOs.
Is the S32M244LCABWKHSR certified for functional safety standards?
Yes, the S32M244LCABWKHSR is designed to comply with ISO 26262 ASIL-B requirements.
