Product details
Overview
FS32K144HRT0MMHT 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 flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +125 °C ambient operation. Used in body control modules, battery management systems, and motor control units requiring ASIL-B compliance.
For engineers reviewing the FS32K144HRT0MMHT datasheet, FS32K144HRT0MMHT pinout, FS32K144HRT0MMHT application, or FS32K144HRT0MMHT equivalent, this page delivers verified technical context, validated pin-level functionality, confirmed safety architecture (CSEc, MPU, ECC), and precise alternative part comparisons - all aligned to the S32K144 family's production-qualified specifications per Rev. 15 (5 March 2026).
Technical Context
The FS32K144HRT0MMHT implements a dual-core-capable Arm Cortex-M4F CPU with integrated FPU and DSP extensions, operating at 112 MHz in HSRUN mode and 80 MHz in RUN mode. Its memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system-level MPU enforcing crossbar-switched access rights per master (core, DMA, Ethernet).
It integrates three FlexCAN modules (with optional CAN-FD), eight FlexTimer modules (64 PWM/IC/OC channels), dual 12-bit ADCs (1 Msps, up to 32 channels each), and low-power peripherals including LPUART, LPSPI, LPI2C, and LPIT - all configurable via TRGMUX and supported in VLPR/VLPS power modes. CSEc cryptographic operations require mode switching from HSRUN (112 MHz) to RUN (80 MHz) to avoid error flag assertion.

FAQ
What is the maximum operating frequency of the FS32K144HRT0MMHT and under what conditions?
The FS32K144HRT0MMHT achieves 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode requires VDD ≥ 2.7 V and ambient temperature ≤ +105 °C; RUN mode supports full -40 °C to +125 °C operation. The device must drop to RUN mode to execute CSEc or EEPROM writes/erase - attempting these in HSRUN triggers error flags. FS32K144HRT0MMHT maintains deterministic timing across both modes via its SPLL and clock gating architecture.
Does the FS32K144HRT0MMHT support CAN FD, and how many interfaces are available?
Yes, the FS32K144HRT0MMHT integrates three FlexCAN modules, all supporting CAN FD protocol with bit rates up to 5 Mbps in the data phase. Each module includes dedicated message RAM, acceptance filtering, and loopback/self-test modes. These interfaces operate independently and can be configured for classic CAN or CAN FD via register settings in the FS32K144HRT0MMHT reference manual.
What safety mechanisms are implemented in the FS32K144HRT0MMHT for ISO 26262 compliance?
The FS32K144HRT0MMHT includes CSEc for cryptographic integrity, system MPU for memory access enforcement, ECC on flash and SRAM, CRC module for data path verification, dual watchdogs (WDOG and EWM), and lockstep-capable peripherals. These features collectively support ASIL-B development per ISO 26262, with diagnostic coverage documented in NXP's FS32K144HRT0MMHT safety manual (Rev. 15).
How much internal flash and SRAM does the FS32K144HRT0MMHT provide, and are they protected?
The FS32K144HRT0MMHT contains 2 MB of program flash memory and 256 KB of SRAM, both with end-to-end ECC protection. Flash includes 64 KB FlexNVM for EEPROM emulation with wear leveling. ECC detection/correction is hardware-managed and transparent to software - single-bit errors are corrected automatically, and double-bit errors trigger interrupts for safe recovery. This applies to all memory accesses in FS32K144HRT0MMHT during normal operation.
Is the FS32K144HRT0MMHT pin-compatible with other S32K14x devices in the same package?
Yes, all S32K14x devices in the 144-pin LQFP package - including FS32K142HRT0MMHT, FS32K144HRT0MMHT, and FS32K146HRT0MMHT - are fully pin-to-pin compatible. Peripheral availability depends on signal mapping in the specific variant, but power, ground, reset, debug, and core I/O pins retain identical placement. This allows hardware reuse across product tiers when migrating from FS32K144HRT0MMHT to higher- or lower-spec variants.
