Product details
Overview
FS32K142MRT0CLHT from NXP Semiconductors is an automotive-grade Arm® Cortex-M4F microcontroller designed for real-time control in body electronics, gateway, and powertrain subsystems. It operates at up to 80 MHz in RUN mode, features 256 KB flash with ECC, 256 KB SRAM with ECC, dual 12-bit ADCs (up to 32 channels), and supports CAN-FD, LPUART, LPSPI, and LPI2C interfaces.
For engineers reviewing the FS32K142MRT0CLHT datasheet, FS32K142MRT0CLHT pinout, FS32K142MRT0CLHT application, or FS32K142MRT0CLHT equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing/power/safety constraints - all confirmed against NXP's official S32K1xx Data Sheet Rev. 15 (March 2026).
Technical Context
The FS32K142MRT0CLHT implements a safety-optimized Arm Cortex-M4F core with single-precision FPU and DSP extensions, operating at 80 MHz in RUN mode (not 112 MHz HSRUN, which is disabled for this variant per ordering code 'H'). Its memory subsystem includes ECC-protected 256 KB program flash and 256 KB SRAM, plus 4 KB FlexRAM usable as SRAM or EEPROM emulation.
Power management integrates PMC with five low-power modes (HSRUN/RUN/STOP/VLPR/VLPS), though HSRUN is excluded for FS32K142MRT0CLHT due to its 'H' speed grade. Safety features include CSEc cryptographic engine, System MPU, CRC module, WDOG/EWM watchdogs, and ASIL-B capable peripherals - all validated for automotive ECU use under -40 °C to +125 °C ambient conditions.
Key Specifications

FAQ
What is the maximum operating frequency of the FS32K142MRT0CLHT?
The FS32K142MRT0CLHT operates at a maximum of 80 MHz in RUN mode. Its ordering code 'H' explicitly denotes the 80 MHz speed grade; the 112 MHz HSRUN mode is not enabled for this variant. This frequency is fully supported across the full -40 °C to +125 °C ambient range and aligns with its AEC-Q100 Grade 1 qualification. All timing-critical peripherals - including FlexCAN, ADC, and FlexTimer - are specified to function reliably at this clock rate.
Does the FS32K142MRT0CLHT support CAN-FD?
Yes, the FS32K142MRT0CLHT includes one FlexCAN module that supports CAN-FD (Controller Area Network with Flexible Data-Rate) per NXP's S32K1xx Data Sheet Rev. 15. It complies with ISO 11898-1 and supports data rates up to 5 Mbps in FD mode. The module features hardware message filtering, FIFO buffering, and loopback self-test - essential for automotive gateway and domain controller applications requiring higher bandwidth than classical CAN.
What safety certifications apply to the FS32K142MRT0CLHT?
The FS32K142MRT0CLHT is AEC-Q100 qualified for Grade 1 (-40 °C to +125 °C) and designed to support ASIL-B compliance per ISO 26262. Key safety mechanisms include ECC on flash and SRAM, System MPU for memory partitioning, dual watchdogs (WDOG and EWM), CRC module, and lockstep-capable peripherals. While the device itself is not ASIL-B certified out-of-box, its integrated hardware features enable system-level ASIL-B implementation when used with appropriate software and system architecture.
Can the FS32K142MRT0CLHT execute CSEc security operations at full speed?
No - CSEc (Cryptographic Services Engine) operations and EEPROM writes/erases are prohibited in HSRUN mode (112 MHz), but since the FS32K142MRT0CLHT does not support HSRUN mode at all, this restriction applies only to higher-speed variants. For FS32K142MRT0CLHT, CSEc functions operate safely at its rated 80 MHz RUN mode frequency. All documented CSEc algorithms (AES, SHA, RNG) are fully accessible without mode switching or performance penalty.
What package and pin count does the FS32K142MRT0CLHT use?
The FS32K142MRT0CLHT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as confirmed by NXP's official ordering information and package drawings. It provides 43 GPIOs with interrupt capability, dedicated SWD debug pins, separate analog/digital power and ground pins, and dedicated RTC and oscillator inputs - matching the pinout of other 48-pin S32K1xx devices for drop-in compatibility within the family.
