Overview
FS32K142UIT0VLHR 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 from 2.7 V to 5.5 V across -40 °C to 105 °C ambient, supports HSRUN mode at 112 MHz, and delivers 1.25 DMIPS/MHz for real-time control in body electronics and powertrain subsystems.
For engineers reviewing the FS32K142UIT0VLHR datasheet, FS32K142UIT0VLHR pinout, FS32K142UIT0VLHR application, or FS32K142UIT0VLHR equivalent, this page provides verified technical context, validated package mapping (100-pin LQFP), confirmed safety features (ASIL-B capable), and two documented alternative parts for functional substitution in automotive ECU designs.
Technical Context
The FS32K142UIT0VLHR implements a dual-core-capable architecture with Arm Cortex-M4F core running up to 112 MHz in HSRUN mode and M0+ core for low-power background tasks. It integrates SPLL clock generation, FIRC/SIRC/LPO oscillators, and configurable power modes including HSRUN, RUN, STOP, VLPR, and VLPS - with mandatory mode switching (to 80 MHz RUN) required for CSEc security operations or EEPROM emulation writes.
Its memory subsystem includes 512 KB ECC-protected program flash, 64 KB FlexNVM for data flash/EEPROM emulation, 64 KB SRAM with ECC, and 4 KB FlexRAM usable as SRAM or EEPROM backup. Peripheral integration includes three FlexCAN modules (CAN-FD capable), three LPSPI, two LPI2C, three LPUART/LIN, eight FlexTimers (64 channels total), and a 12-bit ADC with up to 32 analog inputs per module.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144UIT0VLHR | 1 MB flash, 128 KB SRAM, adds Ethernet MAC and second SAI interface - no change in core, package, or pinout. | Suitable for gateway or domain controller roles requiring TCP/IP stack or audio streaming; over-spec for basic BCM/EPS. | Select when future scalability to Ethernet or expanded memory is required - maintains identical layout and software portability. |
| FS32K142HIT0VLHR | Same flash/SRAM but rated for -40 °C to 125 °C (M-grade); uses 80 MHz RUN mode only - no HSRUN capability. | Targeted at higher-temperature under-hood locations where 112 MHz operation is unnecessary; lower Dhrystone performance (1.25 → 1.0 DMIPS/MHz). | Choose for cost-sensitive, thermally demanding applications where 80 MHz deterministic timing suffices - avoids HSRUN mode constraints on CSEc usage. |
Compared with FS32K142UIT0VLHR, FS32K144UIT0VLHR offers scalable memory and connectivity for evolving domain architectures, while FS32K142HIT0VLHR trades peak performance for extended temperature resilience - both retain identical 100-pin LQFP footprint and automotive qualification.

FAQ
What is the maximum operating frequency of the FS32K142UIT0VLHR and under what conditions?
The FS32K142UIT0VLHR achieves 112 MHz in HSRUN mode, enabled only when ambient temperature is ≤105 °C and supply voltage is ≥2.7 V. This mode is disabled during CSEc cryptographic operations or FlexNVM write/erase cycles, which require switching to 80 MHz RUN mode per NXP documentation. The FS32K142UIT0VLHR must be configured via PMC registers to enter HSRUN, and system clocks must be reconfigured accordingly.
Does the FS32K142UIT0VLHR support CAN-FD, and how many instances are available?
Yes, the FS32K142UIT0VLHR integrates three FlexCAN modules, all supporting CAN-FD protocol per ISO 11898-1:2015. Each module operates independently with configurable bit rates, message buffers, and FD-specific features like flexible data length and fast bit rate switching. The FS32K142UIT0VLHR requires external CAN transceivers for physical layer implementation, and pin assignment depends on selected 100-pin LQFP signal multiplexing.
What memory protection mechanisms are implemented in the FS32K142UIT0VLHR?
The FS32K142UIT0VLHR implements NXP's System Memory Protection Unit (MPU) at the Crossbar Switch level, enabling access rights configuration per master (CPU, DMA, Ethernet) for each protected memory region. It also includes ECC on 512 KB flash and 64 KB SRAM, CRC acceleration module, and dual watchdogs (WDOG + EWM). These mechanisms collectively support ASIL-B compliance per ISO 26262, and are fully active in the FS32K142UIT0VLHR without additional licensing.
Can the FS32K142UIT0VLHR execute secure boot and firmware updates using its built-in security engine?
Yes, the FS32K142UIT0VLHR includes the Cryptographic Services Engine (CSEc), which implements SHE-compliant AES-128/256, SHA-256, HMAC, and true random number generation. It supports secure boot authentication, encrypted firmware image decryption, and key provisioning - all without external security chips. The FS32K142UIT0VLHR requires proper CSEc initialization and key injection during manufacturing, and disables these functions in HSRUN mode per specification.
What is the GPIO count and interrupt capability of the FS32K142UIT0VLHR in its 100-pin LQFP package?
In the 100-pin LQFP package, the FS32K142UIT0VLHR supports up to 89 GPIO pins, each configurable for digital input/output, analog input, or peripheral function multiplexing. All GPIOs support edge-triggered interrupts with programmable polarity and priority via NVIC, and include dedicated Non-Maskable Interrupt (NMI) capability. This GPIO count is validated in the S32K1xx IO Signal Description document for the 100-pin variant, and applies directly to the FS32K142UIT0VLHR.
