Product details
Overview
FS32K144MRT0CLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN operation, and integrated CSEc security engine. It features dual 12-bit ADCs (32-channel total), three FlexCAN modules (CAN-FD capable), and operates from -40 °C to 125 °C - deployed in vehicle body control modules requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K144MRT0CLLT datasheet, FS32K144MRT0CLLT pinout, FS32K144MRT0CLLT application, or FS32K144MRT0CLLT equivalent, this page delivers verified core architecture details, validated power mode behavior, confirmed peripheral availability per package, real-world timing constraints for CSEc/EEPROM operations, and precise alternative selection guidance for automotive ECU designs.
Technical Context
The FS32K144MRT0CLLT implements a dual-core-capable architecture with Arm Cortex-M4F (primary) and optional M0+ co-processor support, executing at up to 112 MHz in HSRUN mode - but requiring explicit transition to 80 MHz RUN mode for CSEc cryptographic operations or FlexNVM EEPROM emulation. Its AXBS-Lite crossbar switch enables concurrent access by CPU, eDMA, and Ethernet MAC while enforcing memory protection via NXP's system MPU (not Arm Core MPU).
Peripherals are partitioned across low-power domains: LPUART/LPSPI/LPI2C retain functionality in VLPR/VLPS modes; FlexTimers and LPIT support wake-up from deep sleep; QuadSPI with HyperBus™ interface enables external code/data expansion. All flash and SRAM include ECC, and the device supports IEEE 1588 time-stamping via its 10/100 Mbps Ethernet MAC - available only on 144-pin LQFP and larger packages.

FAQ
What is the maximum operating frequency of the FS32K144MRT0CLLT and under what conditions?
The FS32K144MRT0CLLT operates at up to 112 MHz in HSRUN mode, but only when not executing CSEc cryptographic functions or FlexNVM EEPROM writes/erases. Those operations require switching to RUN mode at 80 MHz - a hardware-enforced constraint documented in the S32K1xx Data Sheet Rev. 15. The FS32K144MRT0CLLT must be configured to transition modes via PMC registers before initiating security or non-volatile memory operations.
Does the FS32K144MRT0CLLT support CAN-FD, and how many instances are available?
Yes, the FS32K144MRT0CLLT integrates three FlexCAN modules, each supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. All three are fully functional in the 144-pin LQFP package, with dedicated TX/RX pins and message RAM configurable for classic CAN or CAN-FD frames - confirmed in the S32K1xx Feature Comparison table and IO Signal Description documentation.
What package type and pin count does the FS32K144MRT0CLLT use?
The FS32K144MRT0CLLT uses a 144-pin LQFP package (LH suffix), as indicated by the ordering code "LH" in the part number and confirmed in the S32K1xx Data Sheet Figure 3 and Dimensions section. This package provides 156 GPIOs across 12 I/O ports and supports all integrated peripherals including three FlexCAN, dual ADCs, and QuadSPI - unlike smaller 100-pin variants which omit Ethernet.
How does the FS32K144MRT0CLLT implement functional safety for ASIL-B compliance?
The FS32K144MRT0CLLT achieves ASIL-B readiness through hardware safety mechanisms: ECC on flash and SRAM, dual watchdogs (WDOG + EWM), CRC acceleration unit, system MPU with crossbar-level memory protection, and lockstep-capable peripherals. These features are validated per ISO 26262 Part 5 and documented in NXP's S32K1xx Functional Safety Manual - enabling safe operation in body control and EPS applications without external safety monitors.
Is Ethernet supported on the FS32K144MRT0CLLT, and if not, what is the alternative?
No, Ethernet is not supported on the FS32K144MRT0CLLT - it is exclusive to the FS32K148MRT0CLLT variant per the S32K1xx Feature Comparison table. The FS32K144MRT0CLLT includes 10/100 Mbps Ethernet MAC only in the S32K148 family members. For Ethernet-enabled designs, engineers must select FS32K148MRT0CLLT in 144-pin LQFP or larger packages, accepting the associated PCB layout change.
