S32M276LHABMKHST

Microcontrollers Overview

The S32M276LHABMKHST is a System in Package (SiP) automotive microcontroller from the NXP S32M2 family, designed for 12V motor control applications. It integrates an Arm Cortex-M7 processor running at 120 MHz with floating-point capabilities and HSE-B hardware security. The device features 1 MB of flash memory and 128 kB of SRAM including 96 kB TCM. Key integrated components include a 12V regulator, LIN/CXPI physical interface, MOSFET gate driver unit (GDU), and dual 15-bit ADCs. It operates within a temperature range of -40°C to 125°C and supports ISO 26262 ASIL-B functional safety.

Microcontrollers Feature Summary

• Integrates high-voltage analog features and a 12V regulator directly on the package for direct battery connection.
• Includes a dedicated MOSFET Gate Driver Unit (GDU) for driving up to six external power MOSFETs.
• Features built-in physical communication interfaces supporting LIN, CXPI, or CAN FD without external PHYs.
• Provides advanced hardware security via the HSE-B engine and meets ISO 26262 ASIL-B requirements.

Microcontrollers Applications

• Single BLDC or PMSM motor control
• Up to three Brushed DC motors
• Automotive electric pumps
• HVAC actuators

Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm the exact silicon revision and software configuration included. Ensure the selected variant matches the required physical interface option (LIN, CXPI, or CAN FD) as these are distinct part numbers within the same family. Confirm that the temperature grade aligns with your system's thermal design specifications.

Microcontrollers Selection Notes

Select this component when a single-chip solution for 12V motor control is required to minimize board space and component count. The S32M276 offers higher performance and memory compared to the M24x series, suitable for complex algorithms. Consider the available physical interface options; ensure the chosen suffix corresponds to the necessary bus protocol for your vehicle network architecture.

Microcontrollers Part Context

This device belongs to the S32M2xx family, which extends the S32K MCU portfolio by adding high-voltage analog capabilities. It is designed to replace discrete solutions by integrating regulators, drivers, and PHYs into a 64-pin LQFP-EP package. The family targets cost-sensitive automotive electrification applications while maintaining compatibility with the broader S32 software ecosystem.

Microcontrollers Replacement Considerations

Direct substitutes within the S32M276 family include S32M276CHABMKHST (CAN FD) and S32M276CXABMKHST (CXPI). For lower memory requirements, consider the S32M274 series. Cross-family replacement with S32K devices requires significant hardware redesign due to the absence of integrated high-voltage analog features.
