Overview
FS32K142UFT0VLHT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 256 KB flash, 64 KB SRAM, and integrated CSEc security engine. It operates at up to 112 MHz in HSRUN mode (−40 °C to +105 °C), supports FlexCAN with CAN-FD, LPUART/LIN, LPSPI, and LPI2C interfaces, and targets body control modules and gateway applications requiring ASIL-B compliance.
For engineers reviewing the FS32K142UFT0VLHT datasheet, FS32K142UFT0VLHT pinout, FS32K142UFT0VLHT application, or FS32K142UFT0VLHT equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part documentation.
Technical Context
The FS32K142UFT0VLHT 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 256 KB ECC-protected program flash, 64 KB ECC SRAM, 4 KB FlexRAM for EEPROM emulation, and 32 KB code cache.
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). Peripherals include two 12-bit ADCs (32-channel total), eight FlexTimer modules (64 PWM/IC/OC channels), three FlexCAN controllers (one with CAN-FD), and FlexIO for protocol emulation.

FAQ
What is the maximum operating frequency of the FS32K142UFT0VLHT and under what conditions?
The FS32K142UFT0VLHT operates at up to 112 MHz in HSRUN mode, which is supported only within the −40 °C to +105 °C ambient temperature range (V-grade). At temperatures above 105 °C, it must run in RUN mode at 80 MHz. This frequency limit is enforced by hardware and verified per AEC-Q100 stress testing.
Does the FS32K142UFT0VLHT support CAN-FD, and how many CAN interfaces does it include?
Yes, the FS32K142UFT0VLHT includes three FlexCAN modules, with one supporting CAN-FD (ISO 11898-1:2015). The other two operate in classical CAN 2.0B mode. All three are independently configurable and support bit rates up to 5 Mbps in FD mode with flexible data phase arbitration.
What memory protection mechanisms are implemented in the FS32K142UFT0VLHT?
The FS32K142UFT0VLHT integrates NXP's System Memory Protection Unit (MPU) at the crossbar switch level, ECC on 256 KB flash and 64 KB SRAM, CRC module for memory integrity checks, and watchdog timers (WDOG/EWM). These features collectively meet ASIL-B requirements per ISO 26262.
Can the FS32K142UFT0VLHT execute CSEc cryptographic operations while running at 112 MHz?
No - CSEc (Cryptographic Services Engine) operations and EEPROM writes/erases trigger error flags if attempted in HSRUN mode (112 MHz). The device must transition to RUN mode (80 MHz) before initiating these functions, as explicitly documented in the S32K1xx datasheet Rev. 15 Section 1.1 and Figure 3 footnotes.
What package type and pin count does the FS32K142UFT0VLHT use?
The FS32K142UFT0VLHT uses a 100-pin LQFP package (package code LH), with 73 GPIO pins, 10 power/ground pins, and dedicated signal pins for FlexCAN, LPUART, LPSPI, LPI2C, ADC, FlexTimer, and debug interfaces - matching the pinout of other S32K14x devices in the same package variant.
