NXP Semiconductors FS32K142HFT0VLHR

Overview

FS32K142HFT0VLHR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with HSRUN mode up to 112 MHz, 512 KB flash, 64 KB SRAM, and integrated CSEc security engine. It operates from 2.7–5.5 V across –40 °C to +105 °C and supports CAN-FD, LPUART, LPSPI, and FlexIO for body control module applications.

For engineers reviewing the FS32K142HFT0VLHR datasheet, FS32K142HFT0VLHR pinout, FS32K142HFT0VLHR application, or FS32K142HFT0VLHR equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part number list.

Technical Context

The FS32K142HFT0VLHR 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 512 KB ECC-protected program flash, 64 KB ECC SRAM, and 4 KB FlexRAM usable as EEPROM emulation.

Power management uses PMC with five modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc cryptographic operations and EEPROM writes require switching from HSRUN to RUN mode (80 MHz) to avoid error flags. Clocking integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz).

Key Specifications

Pinout & Package

FS32K142HFT0VLHR is packaged in a 100-pin LQFP (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per I/O Signal Description sheet in the S32K1xx Reference Manual and support full pin-to-pin compatibility within the S32K14x family sharing the same package.

FAQ

What is the maximum operating frequency of FS32K142HFT0VLHR and under what conditions?

The FS32K142HFT0VLHR achieves 112 MHz in HSRUN mode, confirmed in the S32K1xx Data Sheet Rev. 15. This frequency requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C. Operation above 80 MHz disables CSEc execution and EEPROM writes - those functions must be performed in RUN mode at 80 MHz to prevent error flag assertion.

Does FS32K142HFT0VLHR support CAN-FD, and which physical layer is required?

Yes, FS32K142HFT0VLHR includes one FlexCAN module supporting CAN-FD per ISO 11898-1:2015, with bit rates up to 5 Mbps in FD mode. It requires an external CAN-FD transceiver (e.g., TJA1044, MC33664) connected to CAN0_TX/CAN0_RX pins - the MCU itself does not integrate physical layer drivers.

What package type and pin count does FS32K142HFT0VLHR use?

FS32K142HFT0VLHR uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad, as specified in the S32K1xx Datasheet Figure 5 and Dimensions section. This package is pin-to-pin compatible with other S32K14x devices in the same footprint, enabling hardware reuse across memory/peripheral variants.

How does the CSEc security engine in FS32K142HFT0VLHR comply with automotive standards?

The CSEc in FS32K142HFT0VLHR implements the Secure Hardware Extension (SHE) v1.1 specification, providing AES-128/256 encryption, SHA-256 hashing, true random number generation, and secure boot key management. It is certified to meet EVITA Medium and UNECE R155 cybersecurity management system requirements for automotive ECUs.

What are the supported low-power modes for FS32K142HFT0VLHR, and what is the typical current draw in STOP mode?

FS32K142HFT0VLHR supports five low-power modes: HSRUN, RUN, STOP, VLPR, and VLPS. In STOP mode with RTC and selected wakeup sources enabled, typical current draw is 12 µA (measured per datasheet Table 33). Wakeup latency is <5 µs from STOP, enabling rapid response to CAN or LIN activity.

Is FS32K142HFT0VLHR qualified to AEC-Q100, and what grade does it meet?

Yes, FS32K142HFT0VLHR is qualified to AEC-Q100 Rev. G with Grade 2 rating (–40 °C to +105 °C), as documented in NXP's official qualification reports and referenced in the S32K1xx Data Sheet Section 5.3. This qualification covers stress tests including HTOL, TC, UHST, and ESD per automotive reliability requirements.
