NXP Semiconductors FS32K142HFT0VLLT

Overview

FS32K142HFT0VLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 512 KB flash, 64 KB SRAM, and integrated CSEc security engine. It operates at up to 80 MHz in RUN mode, supports -40 °C to 105 °C ambient temperature, and features FlexCAN (1 channel), LPUART (3), LPSPI (3), and LPI2C (2) for vehicle body control and powertrain interface applications.

For engineers reviewing the FS32K142HFT0VLLT datasheet, FS32K142HFT0VLLT pinout, FS32K142HFT0VLLT application, or FS32K142HFT0VLLT equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, functional pin definitions, safety-critical timing behavior, and validated alternative parts for ASIL-B automotive designs.

Technical Context

The FS32K142HFT0VLLT implements a dual-core-capable architecture with Arm Cortex-M4F core (80 MHz RUN / 112 MHz HSRUN), FPU, DSP extensions, and NVIC. Its memory subsystem includes ECC-protected 512 KB flash, 64 KB SRAM, and 4 KB FlexRAM configurable as EEPROM emulation - all managed by NXP's system MPU enforcing crossbar-level memory protection.

Power management integrates PMC with five modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc cryptographic operations and EEPROM writes require mode switching from HSRUN (112 MHz) to RUN (80 MHz). Clocking uses SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz).

FAQ

What is the maximum operating frequency of the FS32K142HFT0VLLT in automotive temperature range?

The FS32K142HFT0VLLT operates at up to 80 MHz in RUN mode across its full -40 °C to 105 °C ambient temperature range. While HSRUN mode supports 112 MHz, that frequency is only guaranteed up to 105 °C junction temperature - and CSEc or EEPROM operations require switching to 80 MHz RUN mode per NXP documentation.

Does the FS32K142HFT0VLLT support CAN-FD, and how many channels are available?

Yes, the FS32K142HFT0VLLT includes one FlexCAN module with CAN-FD support compliant with ISO 11898-1. This single channel supports data rates up to 5 Mbps in FD mode and is implemented in the 100-pin LQFP package with dedicated CAN0_TX and CAN0_RX pins.

What memory protection mechanisms does the FS32K142HFT0VLLT implement for functional safety?

The FS32K142HFT0VLLT implements NXP's system MPU - a crossbar-level memory protection unit that assigns access rights per master (CPU, DMA, Ethernet) to protected memory regions. Unlike Arm Core MPU, it monitors all bus masters, satisfying ASIL-B requirements for memory isolation in ISO 26262-compliant designs.

Can the FS32K142HFT0VLLT execute cryptographic operations while running at maximum clock speed?

No. The FS32K142HFT0VLLT triggers error flags if CSEc (Cryptographic Services Engine) operations are attempted in HSRUN mode (112 MHz). Per NXP documentation, the device must switch to RUN mode (80 MHz) to execute AES, SHA, or key management functions - a mandatory design constraint for secure boot and OTA update sequences.

What is the package type and pin count of the FS32K142HFT0VLLT?

The FS32K142HFT0VLLT uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible with other S32K14x devices in the same footprint, enabling scalable design reuse across memory and peripheral variants.
