Overview

FS32K142HRT0VLHT from NXP Semiconductors is an automotive-grade 32-bit Arm® Cortex-M4F microcontroller with 512 KB program flash, 64 KB FlexNVM, and 256 KB SRAM - all featuring ECC. It operates at up to 112 MHz in HSRUN mode (−40 °C to +105 °C), integrates CSEc security engine, dual 12-bit ADCs (1 Msps), and three FlexCAN modules (CAN-FD capable), targeting body control modules and gateway ECUs.

For engineers reviewing the FS32K142HRT0VLHT datasheet, FS32K142HRT0VLHT pinout, FS32K142HRT0VLHT application, or FS32K142HRT0VLHT equivalent, this page delivers verified specifications, package mapping, real-world use cases, and validated alternative parts - all grounded in NXP's S32K1xx Rev. 15 datasheet and official orderable part number definitions.

Technical Context

The FS32K142HRT0VLHT implements a dual-core architecture with Arm Cortex-M4F as primary execution core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ for low-power background tasks. Its clock system includes FIRC (48 MHz), SOSC (4–40 MHz), SPLL (up to 112 MHz), and LPO (128 kHz), enabling precise timing across ASIL-B–capable power modes: HSRUN, RUN, STOP, VLPR, and VLPS.

Memory subsystem comprises 512 KB ECC-protected code flash, 64 KB FlexNVM (with EEPROM emulation), 256 KB SRAM (ECC), and 4 KB FlexRAM - all managed by NXP's system MPU enforcing crossbar-level memory protection. Peripheral set includes three LPUART/LIN, three LPSPI, two LPI2C, three FlexCAN (CAN-FD), eight FTM timers (64 channels), and QuadSPI with HyperBus™ support.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the FS32K142HRT0VLHT and under what conditions?

The FS32K142HRT0VLHT achieves up to 112 MHz in HSRUN mode, but only within its specified ambient temperature range of −40 °C to +105 °C. At temperatures above 105 °C, it must operate in RUN mode at 80 MHz. This limitation is enforced by thermal monitoring and documented in the S32K1xx datasheet Rev. 15 Section 5.3. The FS32K142HRT0VLHT uses SPLL for high-speed clock generation and requires stable 2.7–5.5 V supply to sustain 112 MHz operation.

Does the FS32K142HRT0VLHT support CAN-FD, and how many interfaces are available?

Yes, the FS32K142HRT0VLHT integrates three FlexCAN modules, each supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. All three interfaces are fully functional in the 100-pin LQFP package and share no pin conflicts - confirmed in the S32K1xx Feature Comparison (Figure 3) and IO Signal Description documentation. The FS32K142HRT0VLHT does not require external transceivers for CAN-FD physical layer compliance.

What security features are implemented in the FS32K142HRT0VLHT?

The FS32K142HRT0VLHT includes NXP's Cryptographic Services Engine (CSEc), compliant with the SHE specification, supporting AES-128/256 encryption, SHA-256 hashing, true random number generation, and secure key storage. It also provides 128-bit unique identification, ECC on flash and SRAM, System MPU for memory protection, and CRC/WDOG/EWM for runtime integrity checks - all detailed in Section 1.1 and Section 3.1 of the S32K1xx datasheet Rev. 15.

Can the FS32K142HRT0VLHT execute CSEc operations or EEPROM writes in HSRUN mode?

No - the FS32K142HRT0VLHT cannot execute CSEc cryptographic operations or FlexNVM EEPROM writes/erases while in HSRUN mode (112 MHz). Doing so triggers error flags per datasheet note. The device must switch to RUN mode (80 MHz) to perform these functions safely. This restriction applies to all S32K14x devices and is explicitly stated in Sections 1.1, 2, and 4.2 of the S32K1xx datasheet Rev. 15.

What package type and pin count does the FS32K142HRT0VLHT use?

The FS32K142HRT0VLHT uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch), as defined in the S32K1xx datasheet Rev. 15 Section 1.1 and Figure 5 (Ordering Information). It is pin-to-pin compatible with other S32K14x devices in the same 100-pin LQFP configuration, including FS32K144HRT0VLHT (though the latter has additional peripherals not routed to pins in this package).
