For engineers reviewing the FX32K142UAT0VLHT datasheet, FX32K142UAT0VLHT pinout, FX32K142UAT0VLHT application, or FX32K142UAT0VLHT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for functional safety (ASIL-B capable) automotive embedded designs.
Technical Context
The FX32K142UAT0VLHT implements a dual-core architecture with Arm Cortex-M4F (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support via software configuration. It integrates SPLL-based clock generation up to 112 MHz, FIRC/SIRC/SOSC/LPO oscillators, and dynamic power mode switching across HSRUN, RUN, STOP, VLPR, and VLPS.
Its memory subsystem includes 512 KB ECC-protected program flash, 64 KB FlexNVM for EEPROM emulation, 64 KB SRAM with ECC, and 4 KB FlexRAM configurable as SRAM or EEPROM backup - all managed by NXP's system MPU enforcing crossbar-level memory protection for ASIL-B compliance.

Yes, FX32K142UAT0VLHT includes three FlexCAN modules, with at least one supporting CAN-FD per the S32K142 feature set. CAN-FD operation requires external ISO 11898-2 transceivers and is validated for data rates up to 5 Mbps with bit-rate switching, as confirmed in the S32K1xx Data Sheet Rev. 15.
What package type and pin count does FX32K142UAT0VLHT use?
FX32K142UAT0VLHT uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-to-pin compatible with other S32K14x devices in the same footprint, enabling scalable design reuse across memory/peripheral variants.
Is FX32K142UAT0VLHT qualified for automotive applications?
Yes, FX32K142UAT0VLHT is AEC-Q100 Grade 2 qualified (-40 °C to +105 °C) and designed to meet ISO 26262 ASIL-B requirements. Its system MPU, ECC memory, CRC module, and CSEc engine collectively support functional safety goals in automotive ECU implementations.
