| Safety Certification | ISO 26262 ASIL-B capable - includes System MPU, CRC, watchdogs, and lockstep-ready peripherals for functional safety compliance. |
Pinout & Package
FS32K142HFT0VLLR is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), pin-compatible with other S32K14x devices in the same package option. The device supports up to 89 GPIOs with interrupt capability, multiple analog inputs, and dedicated pins for CAN, SPI, I2C, UART, FlexIO, and debug interfaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power and analog reference supply | Must be decoupled locally; VDD and VDDA require ≤0.1 V differential to ensure ADC/CMP accuracy. |

| SWD_CLK / SWD_IO | Serial Wire Debug interface | Two-pin debug port supporting full JTAG/SWD functionality, trace, and programming without requiring additional pins. |
| CAN0_TX / CAN0_RX | FlexCAN channel 0 differential pair | Supports CAN 2.0B and CAN-FD up to 5 Mbps; requires external transceiver for bus connection. |
| ADC0_SE0–ADC0_SE31 | Analog input channels (ADC0) | Up to 32 single-ended inputs mapped across port pins; configurable sample rates up to 1 MSPS per module. |
Key Features
| Feature | Design Value |
|---|---|
| Cryptographic Services Engine (CSEc) | Hardware-accelerated SHE-compliant crypto (AES-128, SHA-256, RNG, key management) - enables secure boot, firmware authentication, and OTA updates. |
| System Memory Protection Unit (MPU) | NXP's crossbar-level MPU enforces access rights per master (CPU, DMA, Ethernet) - prevents unauthorized memory access across safety-critical domains. |
| Flexible Power Modes | HSRUN, RUN, STOP, VLPR, VLPS - enables dynamic power scaling; HSRUN for peak performance, VLPS for <10 µA sleep current with wake-on-peripheral. |
| FlexIO Module | 8-pin programmable interface supporting UART, SPI, I2C, LIN, PWM, I2S - eliminates need for external protocol translators in mixed-interface systems. |
| Dual 12-bit ADCs with DMA | Two independent 12-bit SAR ADCs, each with up to 32 channels and hardware-triggered conversions - supports simultaneous sensor acquisition in motor control or battery monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144HFT0VLLR | 512 KB flash, 512 KB SRAM, same package and pinout - adds memory headroom for larger AUTOSAR stacks or dual-core partitioning. | Preferred for gateway or domain controller roles requiring extended RTOS footprint or OTA update staging space. | Select when >256 KB flash is needed; identical peripheral set and qualification allow drop-in replacement with layout unchanged. |
| FS32K142HFT0MLLR | Same core and memory, but M-grade (-40 °C to +125 °C) and 64-pin LQFP - lower I/O count, higher thermal rating. | Suitable for compact, high-temperature locations like engine bay sensors where 100-pin footprint is prohibitive. | Choose for space-constrained, thermally aggressive environments; verify I/O mapping matches reduced pin count. |
Compared with FS32K142HFT0VLLR, FS32K144HFT0VLLR offers scalable memory for complex middleware, while FS32K142HFT0MLLR trades pin count and package size for extended temperature range - both retain identical safety architecture, CSEc, and CAN-FD capability.

FAQ
What is the maximum operating frequency of the FS32K142HFT0VLLR?
The FS32K142HFT0VLLR supports up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. Operation at 112 MHz is restricted from executing CSEc cryptographic functions or EEPROM writes/erases; those operations require switching to RUN mode at 80 MHz to avoid error flag generation. This dual-mode architecture balances peak performance with safety-critical task execution.
Does the FS32K142HFT0VLLR support CAN-FD?
Yes, the FS32K142HFT0VLLR includes three FlexCAN modules, each supporting CAN-FD per ISO 11898-1:2015. CAN-FD operation is enabled via configuration registers and requires an external CAN-FD transceiver. The device supports bit rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B networks.
What safety certifications apply to the FS32K142HFT0VLLR?
The FS32K142HFT0VLLR is designed to support ISO 26262 ASIL-B compliance through integrated hardware safety mechanisms: System MPU for memory access control, ECC on flash and SRAM, dual watchdogs (WDOG and EWM), CRC module, and lockstep-ready peripherals. NXP provides safety manuals, FMEDA reports, and diagnostic software libraries to accelerate ASIL-B system certification.
How much SRAM and flash memory does the FS32K142HFT0VLLR include?
The FS32K142HFT0VLLR integrates 256 KB of on-chip program flash memory with ECC protection and 256 KB of SRAM with ECC. It also includes 4 KB of FlexRAM configurable as SRAM or EEPROM emulation, and supports QuadSPI with HyperBus™ for external memory expansion - enabling flexible memory partitioning for safety and security domains.
Is the FS32K142HFT0VLLR pin-compatible with other S32K14x devices?
Yes, the FS32K142HFT0VLLR in the 100-pin LQFP package is pin-to-pin compatible with other S32K14x variants (e.g., FS32K144HFT0VLLR, FS32K146HFT0VLLR) sharing the same package option. This allows hardware reuse across product tiers, provided peripheral usage aligns with the specific variant's feature set - for example, FlexCAN channel count and ADC resolution remain consistent across the 100-pin S32K14x family.
