Product details
Overview
FX32K142UAT0VLLR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 112 MHz HSRUN operation, 256 KB flash, 64 KB SRAM, and integrated CSEc security engine. It supports CAN-FD, LPUART/LIN, LPSPI, LPI2C, FlexIO, and dual 12-bit ADCs-designed for body control modules, gateway ECUs, and battery management systems requiring ASIL-B functional safety compliance.
For engineers reviewing the FX32K142UAT0VLLR datasheet, FX32K142UAT0VLLR pinout, FX32K142UAT0VLLR application, or FX32K142UAT0VLLR equivalent, this page delivers verified technical context, package-specific pin mapping (100-pin LQFP), real-world use-value metrics, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The FX32K142UAT0VLLR implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support in family variants-though FX32K142UAT0VLLR uses M4F exclusively. It integrates SPLL clock synthesis up to 112 MHz, FIRC/SIRC/LPO oscillators, and configurable power modes (HSRUN, RUN, STOP, VLPR, VLPS) with PMC-controlled gating.
Its memory subsystem includes 256 KB ECC-protected program flash, 64 KB ECC SRAM, 4 KB FlexRAM (SRAM/EEPROM emulation), and QuadSPI with HyperBus™ support. Safety features include System MPU (crossbar-level), CRC module, WDOG/EWM, and CSEc cryptographic engine-though CSEc execution requires mode switch from HSRUN (112 MHz) to RUN (80 MHz).
Key Specifications

Pinout & Package
FX32K142UAT0VLLR is housed in a 100-pin LQFP (VLLR) package with exposed thermal pad. Pin assignments are defined in the S32K1xx Reference Manual IO Signal Description sheet; pin functions vary by package size and multiplexing configuration. The 100-pin variant provides full peripheral access including all three FlexCAN modules, dual ADCs, Ethernet MAC pins (not enabled on FX32K142), and 81 GPIOs with interrupt capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply inputs | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O noise margin. |
| RESET_b | Active-low reset input | Asynchronous reset signal; internal pull-up enables reliable power-on reset without external RC network. |
| SWD_CLK, SWD_DIO | Serial Wire Debug interface | Enables non-intrusive debug, trace, and flash programming via standard ARM SWD protocol. |
| CAN0_TX, CAN0_RX | FlexCAN Channel 0 differential pair | Supports ISO 11898-1 CAN-FD up to 5 Mbps; requires external transceiver and termination. |
| ADC0_SE0–ADC0_SE15 | Analog input channels (ADC0) | 16 dedicated pins for first 12-bit ADC module; configurable as single-ended or differential inputs. |
| FTM0_CH0–FTM0_CH7 | FlexTimer Module 0 outputs | Eight PWM/OC/IC-capable pins for motor gate drive, LED dimming, or encoder capture with dead-time insertion. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | System MPU enforces crossbar-level memory protection across CPU, DMA, and Ethernet masters-meeting ISO 26262 requirements without external safety monitor. |
| Low-Power Flexibility | Five power modes (HSRUN/RUN/STOP/VLPR/VLPS) with sub-μA stop-current; LPTMR and LPIT enable wake-from-sleep on analog/digital events within 1 μs. |
| Secure Boot & Runtime Protection | CSEc engine validates signed firmware images at boot and supports encrypted key storage-preventing unauthorized firmware modification or cloning. |
| Flexible Communication Stack | Three FlexCAN (CAN-FD), three LPUART/LIN, three LPSPI, two LPI2C, and FlexIO allow protocol emulation-reducing BOM count in multi-bus vehicle networks. |
| Robust Analog Integration | Dual 12-bit ADCs with hardware trigger synchronization, 8-bit DAC-integrated comparator, and PDB for precise timing-critical analog acquisition (e.g., battery cell monitoring). |
Applications
| Body Control Module (BCM) | Automotive Gateway ECU |

FAQ
What is the maximum operating frequency of FX32K142UAT0VLLR and under what conditions?
FX32K142UAT0VLLR operates at up to 112 MHz in HSRUN mode, guaranteed across -40 °C to +105 °C ambient temperature and 2.7 V to 5.5 V supply. This frequency requires SPLL configuration and is not permitted during CSEc execution or EEPROM operations, which mandate switching to 80 MHz RUN mode per datasheet Section 1.1 and Figure 3 notes.
Does FX32K142UAT0VLLR support CAN-FD, and how many instances are available?
Yes, FX32K142UAT0VLLR integrates three FlexCAN modules, all supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. All three are accessible in the 100-pin LQFP package (VLLR), with dedicated TX/RX pins assigned per channel in the IO Signal Description document.
What memory protection mechanisms does FX32K142UAT0VLLR provide for ASIL-B compliance?
FX32K142UAT0VLLR implements a System MPU at the Crossbar Switch level-not the Arm core MPU-to enforce memory access rights for CPU, DMA, and Ethernet masters independently. Combined with ECC on flash and SRAM, CRC module, WDOG/EWM, and CSEc, it meets ASIL-B requirements per ISO 26262 without external safety components.
Can FX32K142UAT0VLLR execute cryptographic operations while running at 112 MHz?
No. CSEc (Cryptographic Services Engine) execution is explicitly prohibited in HSRUN mode (112 MHz) per datasheet Section 1.1 and Figure 3 footnote. FX32K142UAT0VLLR must transition to RUN mode (80 MHz) before initiating CSEc operations-including secure boot verification, AES encryption, or key generation-to avoid error flag assertion.
What is the ADC resolution and sampling rate supported by FX32K142UAT0VLLR?
FX32K142UAT0VLLR includes two independent 12-bit SAR ADC modules, each supporting up to 1 Msps conversion rate. Each module accepts up to 32 analog input channels (multiplexed), with hardware synchronization via PDB enabling simultaneous sampling across both ADCs for phase-matched measurements.
