Overview
FS32K144MNT0MLHR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM, and integrated CSEc security engine. It operates at up to 112 MHz in HSRUN mode (−40 °C to +125 °C), supports FlexCAN with CAN-FD, dual 12-bit ADCs (1 Msps), and IEEE-1588 Ethernet - deployed in body control modules and gateway ECUs.
For engineers reviewing the FS32K144MNT0MLHR datasheet, FS32K144MNT0MLHR pinout, FS32K144MNT0MLHR application, or FS32K144MNT0MLHR equivalent, key selection criteria include ASIL-B capable safety architecture, HSRUN/RUN mode switching for EEPROM/CSEc operations, 144-pin LQFP package compatibility, and S32K1xx SDK support in NXP S32 Design Studio.
Technical Context
The FS32K144MNT0MLHR implements a dual-core execution context via Arm Cortex-M4F with FPU and optional M0+ co-processor support in family variants; its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), and LPO (128 kHz) with dynamic mode switching between HSRUN, RUN, STOP, VLPR, and VLPS. Memory subsystem includes ECC-protected 2 MB flash, 64 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM configurable as SRAM or EEPROM.
Safety and security are enforced through NXP's system MPU (crossbar-level memory protection), CSEc cryptographic engine (SHE-compliant), CRC module, dual watchdogs (WDOG + EWM), and hardware-assisted DMA with DMAMUX routing across 63 request sources - all validated per ISO 26262 up to ASIL-B.

FAQ
What is the maximum operating frequency of the FS32K144MNT0MLHR and under what conditions?
The FS32K144MNT0MLHR achieves a maximum operating frequency of 112 MHz in HSRUN mode, validated across −40 °C to +125 °C ambient temperature. This mode requires VDD ≥ 2.7 V and disables CSEc cryptographic operations and EEPROM writes; those functions must execute in 80 MHz RUN mode to prevent error flag assertion. The device automatically transitions between modes via PMC register configuration.
Does the FS32K144MNT0MLHR support CAN-FD, and how many instances are available?
Yes, the FS32K144MNT0MLHR integrates three FlexCAN modules, all supporting CAN-FD protocol (ISO 11898-1) with data rates up to 5 Mbps. Each module includes dedicated message RAM, acceptance filtering, and loopback/self-test capability. CAN-FD operation is enabled by default in the S32K1xx SDK and requires external CAN transceivers compliant with ISO 11898-2/5.
How does the CSEc (Cryptographic Services Engine) function in the FS32K144MNT0MLHR?
The CSEc in FS32K144MNT0MLHR is a hardware-accelerated SHE-compliant engine implementing AES-128/256, SHA-256, RSA-2048, and secure boot verification. It operates independently of the CPU core, uses dedicated key storage, and enforces strict access control via the system MPU. CSEc commands must be issued in RUN mode (80 MHz), as HSRUN mode triggers error flags during execution.
What package type and pin count does the FS32K144MNT0MLHR use?
The FS32K144MNT0MLHR is supplied in a 144-pin LQFP package with 0.5 mm pitch and 20 × 20 mm body size. It is pin-to-pin compatible with other S32K14x devices in the same package option, enabling scalable design reuse across performance tiers. Thermal pad exposure supports enhanced heat dissipation in automotive under-hood environments.
Is the FS32K144MNT0MLHR qualified for automotive safety standards?
Yes, the FS32K144MNT0MLHR is qualified to ISO 26262 up to ASIL-B, with safety mechanisms including system MPU-based memory protection, dual watchdogs (WDOG and EWM), CRC hardware acceleration, ECC on flash and SRAM, and lockstep-capable peripheral modules. Functional safety documentation, FMEDA reports, and safety manuals are provided by NXP for integration into certified automotive software stacks.
