Product details
Overview
FS32K144HAT0VMHT 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 +125 °C ambient operation. Used in body control modules, gateway controllers, and battery management systems requiring ASIL-B compliance.
For engineers reviewing the FS32K144HAT0VMHT datasheet, FS32K144HAT0VMHT pinout, FS32K144HAT0VMHT application, or FS32K144HAT0VMHT equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support tailored for automotive embedded design and production ramp-up.
Technical Context
The FS32K144HAT0VMHT implements a dual-core-capable architecture with Arm Cortex-M4F core (Armv7-M, Thumb-2 ISA) and integrated Single Precision FPU, DSP extensions, and configurable NVIC. It integrates SPLL-based clock generation supporting up to 112 MHz system frequency, with independent low-power oscillators (FIRC, SIRC, LPO) and RTC_CLKIN input.
Power management includes five operational modes (HSRUN, RUN, STOP, VLPR, VLPS), PMC-controlled clock gating, and mandatory mode switching-CSEc security operations and EEPROM emulation require transition from HSRUN (112 MHz) to RUN (80 MHz) to avoid error flag assertion. Memory subsystem includes ECC-protected flash/SRAM, FlexNVM for data storage, and QuadSPI with HyperBus™ support.

FAQ
What is the maximum operating frequency of the FS32K144HAT0VMHT?
The FS32K144HAT0VMHT achieves up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. Its System PLL (SPLL) generates the high-frequency clock, while the FIRC (48 MHz) and SIRC (8 MHz) provide low-power alternatives. Operation above 80 MHz requires VDD ≥ 2.7 V and disables CSEc execution and EEPROM writes - those functions must be performed in RUN mode.
Does the FS32K144HAT0VMHT support CAN-FD?
Yes, the FS32K144HAT0VMHT integrates three FlexCAN modules, each supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. The CAN-FD capability is enabled by default in the silicon and configured via register settings in the S32K1xx SDK; no external components are required beyond a standard CAN transceiver.
What package type does the FS32K144HAT0VMHT use?
The FS32K144HAT0VMHT uses a 144-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch, exposed thermal pad, and RoHS compliance. This package is pin-compatible with other S32K14x devices in the same footprint, enabling scalable design reuse across performance tiers within the family.
How does the CSEc security engine function on the FS32K144HAT0VMHT?
The Cryptographic Services Engine (CSEc) on the FS32K144HAT0VMHT implements AES-128, SHA-256, HMAC, RNG, and secure boot key management per the SHE specification. It operates only in RUN mode (80 MHz); attempting CSEc operations in HSRUN mode triggers error flags and requires explicit mode transition before execution.
Is the FS32K144HAT0VMHT qualified for automotive safety standards?
Yes, the FS32K144HAT0VMHT is designed to support ISO 26262 ASIL-B compliance through integrated safety mechanisms: ECC on flash and SRAM, system MPU, CRC module, dual watchdogs (WDOG/EWM), lockstep-capable peripherals, and FMEDA documentation provided by NXP. Full qualification evidence is available in the S32K1xx Functional Safety Package.
