Product details
Overview
FS32K144MNT0VLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for real-time control in safety-critical ECUs. It operates at up to 112 MHz (HSRUN mode), features 2 MB program flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to 105 °C ambient operation. It integrates FlexCAN with optional CAN-FD, LPUART/LIN, LPSPI, and CSEc cryptographic engine - deployed in body control modules and battery management systems.
For engineers reviewing the FS32K144MNT0VLLT datasheet, FS32K144MNT0VLLT pinout, FS32K144MNT0VLLT application, or FS32K144MNT0VLLT equivalent, key selection criteria include HSRUN/RUN mode switching constraints for CSEc/EEPROM operations, 144-pin LQFP package compatibility, ASIL-B capable safety architecture, and voltage range (2.7–5.5 V) compliance for 12 V automotive systems.
Technical Context
The FS32K144MNT0VLLT implements a dual-core-capable architecture with Arm Cortex-M4F core (Armv7, Thumb-2 ISA), integrated DSP, single-precision FPU, and configurable NVIC. Its clock system includes SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL supporting up to 112 MHz system frequency.
Power management uses PMC with five modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc security or EEPROM emulation requires explicit transition from HSRUN (112 MHz) to RUN (80 MHz). Memory subsystem includes ECC-protected flash/SRAM, QuadSPI with HyperBus™ support, and FlexNVM enabling EEPROM emulation via 64 KB data flash.

FAQ
What is the maximum operating frequency of the FS32K144MNT0VLLT?
The FS32K144MNT0VLLT achieves up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. Operation at 112 MHz requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C. The device automatically transitions between modes based on software-configured power states and peripheral activity - FS32K144MNT0VLLT must drop to RUN mode for CSEc or EEPROM operations.
Does the FS32K144MNT0VLLT support CAN-FD?
Yes, the FS32K144MNT0VLLT supports CAN-FD through its three FlexCAN modules, with configuration enabled via register settings and SDK drivers. CAN-FD operation requires external CAN-FD transceivers and is validated per ISO 11898-1:2015; FS32K144MNT0VLLT delivers up to 5 Mbps data phase rates in FD mode.
What package type and pin count does the FS32K144MNT0VLLT use?
The FS32K144MNT0VLLT uses a 144-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible with other S32K14x devices in the same footprint, enabling hardware reuse across performance variants - FS32K144MNT0VLLT shares identical mechanical and thermal characteristics with S32K146MNT0VLLT and S32K148MNT0VLLT in this package.
How does the CSEc security engine function in the FS32K144MNT0VLLT?
The CSEc engine in FS32K144MNT0VLLT implements SHE-compliant cryptographic functions including AES-128/256, SHA-256, HMAC, and TRNG. It operates independently of the main CPU and supports secure boot, firmware encryption, and key provisioning. Critically, FS32K144MNT0VLLT requires transition from HSRUN to RUN mode (80 MHz) before initiating CSEc commands to avoid error flag assertion.
Is the FS32K144MNT0VLLT qualified for automotive applications?
Yes, the FS32K144MNT0VLLT is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C), supports ISO 26262 ASIL-B development flow, and includes hardware safety mechanisms such as ECC, system MPU, CRC, WDOG, and EWM.
