Product details
Overview
S32M241LCABMKHSR from NXP Semiconductors is an automotive-grade System-in-Package (SiP) microcontroller integrating an Arm Cortex-M4F core @ 80 MHz, 128 kB flash, 32 kB SRAM, and a 6-channel MOSFET gate driver unit for BLDC/PMSM motor control. It features integrated 12 V voltage regulation, LIN/CXPI/CAN-FD physical layer, 5 V/30 mA auxiliary supply, and ASIL-B compliance - deployed in single-motor automotive body electronics such as electric power steering assist modules.
For engineers reviewing the S32M241LCABMKHSR datasheet, S32M241LCABMKHSR pinout, S32M241LCABMKHSR application, or S32M241LCABMKHSR equivalent, key selection criteria include its Grade M (-40°C to +125°C) thermal rating, LQFP-EP 64-pin package with exposed pad, integrated high-voltage analog front-end (HVI, DPGA, VM), and functional safety support via CSEc hardware security engine.
Technical Context
The S32M241LCABMKHSR implements a dual-domain SiP architecture: an MCU subsystem (Cortex-M4F, flash/SRAM, peripherals) tightly coupled with an Application Extension (AE) subsystem containing high-voltage regulators, LIN/CXPI/CAN-FD PHYs, and a 6-channel MOSFET pre-driver. The AE domain operates directly from 12 V battery input (VSUP = 3.5–40 V), enabling direct connection to automotive power rails without external DC-DC conversion.
Its gate driver unit supports three-phase BLDC/PMSM control with internal PWM logic routing from FlexTimer modules, while the DPGA enables single-shunt current sensing and HVI provides battery voltage monitoring. All analog measurement paths (ADC, DPGA, HVI, VM, temperature sensor) are internally routed to two 12-bit ADCs with PDB-triggered sampling.
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. |
| Flash / SRAM | 128 kB program flash + 32 kB SRAM - sufficient for AUTOSAR MCAL stack, safety monitors, and closed-loop motor firmware. |
| Operating Temp | -40°C to +125°C (Grade M) - qualified for under-hood automotive environments including EPS and HVAC actuators. |
| Supply Input | VSUP: 3.5–40 V - accepts full automotive battery range including load dump transients up to 40 V (t < 400 ms). |
| Integrated PHY | LIN/CXPI/CAN-FD physical interface - eliminates need for external transceiver in LIN-based seat/mirror/door modules. |
| GDU Channels | 6-channel MOSFET pre-driver (3-phase) - drives external high-side/low-side N-channel MOSFETs with bootstrap and charge pump support. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32M242LCABMKHSR | 256 kB flash, 32 kB SRAM - identical peripheral set and pinout. | Same motor control use cases but supports larger firmware (e.g., dual-motor control + diagnostics stack). | Select when firmware size exceeds 128 kB or future scalability is required; no PCB change needed. |
| S32K144WFT0VLHT | Standalone S32K1 MCU (no integrated GDU, no HV regulator, no LIN/CAN-FD PHY); requires external drivers and transceivers. | Used in modular designs where motor drive stage is separate; higher BOM cost but greater flexibility in MOSFET selection. | Choose for non-integrated architectures or when leveraging existing S32K software ecosystem; requires full external analog/power interface. |
Compared with S32M241LCABMKHSR, S32M242LCABMKHSR offers double flash capacity with identical packaging and safety features, while S32K144WFT0VLHT shifts system integration burden to external components - making it suitable only when modularity or legacy S32K toolchain reuse outweighs SiP-level optimization.

FAQ
What is the maximum allowable VSUP voltage for continuous operation of the S32M241LCABMKHSR?
The S32M241LCABMKHSR supports continuous operation at VSUP up to 18 V. Operation at 32.5 V is permitted only for ≤1 hour over lifetime (e.g., during load dump), and 40 V is allowed for transient pulses <400 ms. Exceeding these limits risks permanent damage to the internal 12 V regulator and AE subsystem.
Does the S32M241LCABMKHSR support CAN FD communication out of the box?
Yes, the S32M241LCABMKHSR includes an integrated CAN-FD physical layer. When ordered with 'C' in the communications option field (as in S32M241LCABMKHSR), the CAN0 module is internally connected to the CAN-FD PHY - enabling direct connection to CAN-FD bus without external transceiver.
How is functional safety implemented in the S32M241LCABMKHSR?
The S32M241LCABMKHSR achieves ASIL-B compliance through hardware redundancy (lockstep CPU cores), memory ECC, clock and voltage monitors, SW watchdog, and CSEc-based secure boot. Safety mechanisms are documented in the S32M24x Functional Safety Manual and validated per ISO 26262 Part 5.
Can the S32M241LCABMKHSR drive external MOSFETs without bootstrap components?
No. The S32M241LCABMKHSR's GDU requires external bootstrap capacitors (220 nF recommended) on each high-side channel (VBS0–VBS2) and charge pump components (CP, CP1, VCP) to sustain gate drive voltage during 100% duty cycle operation - per Figure 1 in the datasheet.
What is the purpose of the VPRE pin on the S32M241LCABMKHSR?
The VPRE pin enables external pre-regulation of the internal 12 V supply using a P-channel FET controlled by GCTL. This reduces on-die power dissipation and prevents junction temperature exceedance in high-ambient, high-load conditions - particularly critical in sealed EPS modules.
