Product details
Overview
FS32K142HAT0MLFT 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 80 MHz in RUN mode, supports 2.7–5.5 V supply, features 256 KB flash with ECC, 32 KB SRAM, and -40 °C to +125 °C ambient operation - deployed in engine control modules requiring ASIL-B compliance and deterministic timing.
For engineers reviewing the FS32K142HAT0MLFT datasheet, FS32K142HAT0MLFT pinout, FS32K142HAT0MLFT application, or FS32K142HAT0MLFT equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical context for automotive powertrain and chassis systems - including CAN-FD communication, FlexTimer-based PWM generation, and CSEc security execution constraints.
Technical Context
The FS32K142HAT0MLFT implements a dual-core-capable architecture with Arm Cortex-M4F core (Thumb-2 ISA, single-precision FPU, DSP extensions) and integrated system-level safety mechanisms including System MPU, CRC module, WDOG, EWM, and ECC on flash/SRAM. Its clock system includes FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), SOSC (4–40 MHz), and SPLL supporting up to 80 MHz in RUN mode.
Power management supports five modes (HSRUN, RUN, STOP, VLPR, VLPS); however, FS32K142HAT0MLFT restricts CSEc security operations and EEPROM emulation to RUN mode (80 MHz), disabling them in HSRUN due to concurrent access conflict - a hardware-enforced constraint confirmed across all S32K14x M-grade parts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with FPU and DSP extensions - enables floating-point math and signal processing for motor control algorithms. |

FAQ
What is the maximum operating frequency of the FS32K142HAT0MLFT?
The FS32K142HAT0MLFT operates at up to 80 MHz in RUN mode. It does not support HSRUN mode (112 MHz) - that capability is reserved for higher-memory variants like FS32K144 and FS32K146. This 80 MHz limit is hardware-enforced and documented in the S32K1xx Data Sheet Rev. 15 for all M-grade 48-pin LQFP parts, ensuring thermal and timing stability in under-hood environments.
Does the FS32K142HAT0MLFT support CAN-FD?
Yes, the FS32K142HAT0MLFT includes one FlexCAN module with optional CAN-FD support, enabled via configuration of the CAN control registers and use of appropriate transceivers. The device supports ISO 11898-1 CAN-FD frames up to 5 Mbps, and its 48-pin LQFP package allocates dedicated CAN0_TX and CAN0_RX pins - confirmed in the S32K1xx IO Signal Description document.
Can CSEc security functions be executed in HSRUN mode on the FS32K142HAT0MLFT?
No. CSEc (Cryptographic Services Engine) operations - including AES encryption, key derivation, and secure boot verification - are explicitly prohibited in HSRUN mode on FS32K142HAT0MLFT. The device must be in RUN mode (80 MHz) to execute any CSEc command; attempting CSEc in HSRUN triggers error flags and halts secure operation - a silicon-level restriction stated in multiple sections of the S32K1xx Data Sheet Rev. 15.
What package type and pin count does the FS32K142HAT0MLFT use?
The FS32K142HAT0MLFT uses a 48-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch and exposed thermal pad. This package is pin-to-pin compatible with other S32K14x 48-pin LQFP variants (e.g., FS32K144HAT0MLFT), enabling scalable design reuse. Mechanical dimensions and land pattern match NXP's standard S32K14x 48LQFP drawing (SOT669-2).
Is the FS32K142HAT0MLFT qualified for automotive under-hood applications?
Yes. The FS32K142HAT0MLFT is M-grade qualified for -40 °C to +125 °C ambient operation and meets AEC-Q100 Grade 1 requirements. Its thermal design supports junction temperatures up to 135 °C in RUN mode, and it includes automotive-specific features such as EWM (External Watchdog Monitor), voltage ramp rate compliance, and robust ESD immunity - all validated per ISO 16750 and automotive reliability test plans.
