Product details
Overview
FS32K142HAT0VLHT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 112 MHz HSRUN mode operation, 512 KB flash memory, 64 KB SRAM, and integrated CSEc security engine. It supports CAN-FD, LPUART/LIN, LPSPI, LPI2C, FlexIO, and dual 12-bit ADCs - deployed in body control modules, battery management systems, and chassis domain controllers.
For engineers reviewing the FS32K142HAT0VLHT datasheet, FS32K142HAT0VLHT pinout, FS32K142HAT0VLHT application, or FS32K142HAT0VLHT equivalent, key selection considerations include its -40 °C to 105 °C ambient rating (V-grade), 48-pin LQFP package, HSRUN/RUN power mode switching requirement for CSEc/EEPROM operations, and ASIL-B capable safety architecture per ISO 26262.
Technical Context
The FS32K142HAT0VLHT implements a dual-core-capable Arm Cortex-M4F core with single-precision FPU and DSP extensions, operating at up to 112 MHz in HSRUN mode (80 MHz in RUN mode). Its clock system integrates SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), with configurable clock gating across peripherals.
Memory subsystem includes 512 KB ECC-protected program flash, 64 KB FlexNVM for EEPROM emulation, 64 KB SRAM with ECC, and 4 KB FlexRAM usable as SRAM or EEPROM backup. Safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc cryptographic engine compliant with SHE specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
FS32K142HAT0VLHT is housed in a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow NXP's S32K14x family pin compatibility matrix; all 48-pin LQFP variants are pin-to-pin compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled with 100 nF + 1 µF capacitors; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy. |
| RESET_B | Active-low reset input | Accepts external reset assertion; internal POR and LVD provide fail-safe startup sequencing. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and runtime trace via ARM CoreSight infrastructure. |
| CAN0_TX / CAN0_RX | FlexCAN channel 0 differential pair | Supports CAN-FD up to 5 Mbps; requires external transceiver (e.g., TJA1044T) for physical layer compliance. |
| ADC0_SE0–ADC0_SE15 | Analog input channels (Bank 0) | 16 single-ended inputs mapped to dedicated pins; supports hardware-triggered conversions synchronized to PWM timers. |
| FTM0_CH0–FTM0_CH7 | FlexTimer module outputs | Configurable as PWM, input capture, or output compare; used for LED dimming, motor phase control, and encoder counting. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU enforces memory access rights per master (CPU/DMA/Ethernet); ECC on flash/SRAM prevents silent data corruption. |
| Cryptographic Services Engine (CSEc) | Hardware-accelerated AES-128/256, SHA-256, RNG, and secure boot key management - meets SHE Level 3 requirements. |
| Low-Power Operation | Five power modes (HSRUN/RUN/STOP/VLPR/VLPS); VLPS achieves ~2 µA current draw with RTC wake-up and GPIO interrupt retention. |
| FlexIO Programmable Interface | 8-pin module emulates UART, SPI, I2C, I2S, LIN, or custom protocols - eliminates need for external protocol bridge ICs. |
| Dual 12-bit ADC with Trigger Mux | Two independent ADCs support simultaneous sampling; TRGMUX enables precise synchronization to FTM/PDB events for motor control timing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K144HAT0VLHT | 2 MB flash, 256 KB SRAM, 100-pin LQFP - adds Ethernet MAC and second FlexCAN with FD. | Required for gateway ECUs needing IEEE 1588 time-synchronized CAN/Ethernet bridging. | Select when >512 KB flash or Ethernet PHY interface is mandatory; not pin-compatible due to larger package. |
| S32K142HAT0MLHT | Same core/peripherals but M-grade (-40 °C to 125 °C); operates at 80 MHz max (no HSRUN mode). | Targeted for under-hood applications where junction temperature exceeds 125 °C (e.g., near exhaust manifold). | Choose for higher ambient tolerance; sacrifices 112 MHz performance and disables HSRUN-specific optimizations. |
Compared with FS32K142HAT0VLHT, S32K144HAT0VLHT offers greater memory and connectivity at the cost of PCB footprint and layout redesign, while S32K142HAT0MLHT trades peak frequency for extended thermal range - neither is pin-compatible, requiring board revision for migration.

FAQ
What is the maximum operating frequency of the FS32K142HAT0VLHT, and under what conditions?
The FS32K142HAT0VLHT achieves 112 MHz in HSRUN mode, but only within its -40 °C to 105 °C ambient temperature range and with VDD ≥ 2.7 V. For CSEc cryptographic operations or FlexNVM EEPROM emulation, it must drop to 80 MHz RUN mode - a hardware-enforced restriction documented in the S32K1xx Data Sheet Rev. 15.
Does the FS32K142HAT0VLHT support CAN-FD, and which channel implements it?
Yes, the FS32K142HAT0VLHT includes one FlexCAN module supporting CAN-FD (ISO 11898-1:2015) at data rates up to 5 Mbps. This capability is enabled on CAN0 (pins PTB0/PTB1) and requires external CAN-FD transceiver integration per physical layer specifications.
What package type and pin count does the FS32K142HAT0VLHT use?
The FS32K142HAT0VLHT uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. It is pin-to-pin compatible with other S32K14x 48-pin LQFP variants, including S32K142HAT0MLHT and S32K142HAT0NLHT, enabling shared PCB designs across temperature grades.
How does the CSEc engine in the FS32K142HAT0VLHT support secure boot and firmware updates?
The CSEc engine in the FS32K142HAT0VLHT provides hardware-accelerated AES-128/256 encryption, SHA-256 hashing, and true random number generation. It enables secure boot by verifying signed firmware images prior to execution and supports authenticated OTA updates via encrypted CAN-FD frames - all compliant with SHE Level 3 functional requirements.
What are the memory resources available on the FS32K142HAT0VLHT?
The FS32K142HAT0VLHT integrates 512 KB of ECC-protected program flash, 64 KB of FlexNVM for EEPROM emulation (with ECC), 64 KB of ECC-protected SRAM, and 4 KB of FlexRAM usable as additional SRAM or EEPROM backup - totaling 644 KB of on-chip nonvolatile and volatile memory optimized for automotive reliability.
