Product details
Overview
FS32K144MST0CLHT 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 +105 °C), supports CAN-FD, FlexCAN, LPUART/LIN, and Ethernet MAC, and targets body control modules and gateway ECUs requiring ASIL-B functional safety compliance.
For engineers reviewing the FS32K144MST0CLHT datasheet, FS32K144MST0CLHT pinout, FS32K144MST0CLHT application, or FS32K144MST0CLHT equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options - all grounded in NXP's official S32K1xx Rev. 15 datasheet and orderable part number documentation.
Technical Context
The FS32K144MST0CLHT implements a dual-core-capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN), integrated FPU, DSP extensions, and configurable NVIC. Its memory subsystem includes ECC-protected 2 MB flash, 256 KB SRAM, 64 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM.
Power management is handled by the PMC supporting five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), with clock gating and dynamic voltage scaling. Safety features include System MPU, CRC module, WDOG/EWM, and CSEc cryptographic engine - though CSEc execution requires switching from HSRUN to RUN mode (80 MHz) to avoid error flags.

FAQ
What is the maximum operating frequency of the FS32K144MST0CLHT, and under what conditions is it guaranteed?
The FS32K144MST0CLHT achieves up to 112 MHz in HSRUN mode, guaranteed across −40 °C to +105 °C ambient temperature with 2.7 V to 5.5 V supply. Operation at this frequency requires disabling CSEc execution and EEPROM writes, which must instead run at 80 MHz in RUN mode per NXP's documented constraint.
Does the FS32K144MST0CLHT support CAN-FD, and how many CAN interfaces does it include?
Yes, the FS32K144MST0CLHT integrates three FlexCAN modules, each supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. All three are accessible in the 144-pin LQFP package, enabling simultaneous communication on multiple vehicle networks such as powertrain, chassis, and body domains.
What package type and pin count does the FS32K144MST0CLHT use, and is it pin-compatible with other S32K1xx devices?
The FS32K144MST0CLHT uses a 144-pin LQFP package with 0.5 mm pitch. Per NXP's datasheet, all S32K1xx devices sharing the same package (e.g., 144-pin LQFP) are pin-to-pin compatible - enabling hardware reuse across variants like S32K142, S32K144, and S32K146 without layout changes.
How does the CSEc security engine function on the FS32K144MST0CLHT, and what limitations apply?
The CSEc engine on FS32K144MST0CLHT implements SHE-compliant cryptographic functions (AES-128, SHA-256, RNG) and secure boot verification. However, CSEc execution - along with EEPROM write/erase - is prohibited in HSRUN mode (112 MHz); the device must switch to RUN mode (80 MHz) to avoid triggering error flags and ensure reliable operation.
What is the flash and SRAM capacity of the FS32K144MST0CLHT, and how is ECC implemented?
The FS32K144MST0CLHT includes 2 MB of program flash memory and 256 KB of SRAM, both protected by Error-Correcting Code (ECC). ECC operates transparently in hardware, detecting and correcting single-bit errors and detecting double-bit errors - critical for maintaining data integrity in automotive safety-critical applications per ISO 26262.
