Product details
Overview
FS32K142HAT0VLFR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with HSRUN mode up to 112 MHz, 512 KB flash, 64 KB SRAM, and integrated CSEc security engine. It operates from 2.7–5.5 V across –40 °C to +105 °C and supports CAN-FD, LPUART, LPSPI, and FlexIO for body control module applications.
For engineers reviewing the FS32K142HAT0VLFR datasheet, FS32K142HAT0VLFR pinout, FS32K142HAT0VLFR application, or FS32K142HAT0VLFR equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing/security constraints - including mandatory RUN-mode execution for CSEc operations and EEPROM emulation.
Technical Context
The FS32K142HAT0VLFR implements a dual-core-capable architecture with Arm Cortex-M4F (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support. Its memory subsystem includes 512 KB ECC-protected program flash, 64 KB ECC SRAM, and 4 KB FlexRAM configurable as SRAM or EEPROM emulation.
Power management uses five distinct modes (HSRUN, RUN, STOP, VLPR, VLPS), with CSEc cryptographic operations and EEPROM writes explicitly prohibited in HSRUN mode - requiring runtime mode switching to RUN (80 MHz). Clocking integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz) with configurable gating per peripheral.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4F with single-precision FPU and DSP extensions; enables real-time motor control and sensor fusion at 112 MHz in HSRUN mode. |
| Flash Memory | 512 KB program flash with ECC; supports over-the-air (OTA) updates with error detection and correction for ASIL-B compliance. |
| SRAM | 64 KB on-chip SRAM with ECC; provides fault-tolerant data storage for safety-critical variables in automotive control loops. |
| Operating Voltage | 2.7 V to 5.5 V supply range; compatible with 3.3 V and 5 V automotive domains without level-shifting. |
| Temperature Range | –40 °C to +105 °C ambient; qualified for under-hood body electronics and gateway modules per AEC-Q100 Grade 2. |
| CAN Interface | One FlexCAN module with ISO 11898-1 CAN-FD support; enables high-bandwidth diagnostics and ECU-to-ECU communication at up to 5 Mbps. |
| Security Engine | Cryptographic Services Engine (CSEc); implements SHE-compliant AES-128, SHA-256, and key management - but requires RUN mode (80 MHz), not HSRUN. |
Pinout & Package
FS32K142HAT0VLFR is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows NXP's S32K14x family layout, supporting full GPIO remapping via I/O signal multiplexing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power and analog reference | Must be decoupled with 100 nF + 10 µF capacitors; VDDA and VDD shorted on PCB per AN5032 for ADC accuracy. |
| RESET_B | Active-low reset input | Asynchronous reset with internal pull-up; compatible with external watchdog (EWM) or power supervisor ICs. |
| SWD_CLK, SWD_IO | Serial Wire Debug interface | Enables non-intrusive debug, trace, and flash programming using standard ARM SWD protocol. |
| CAN0_TX, CAN0_RX | FlexCAN differential pair | Requires external 120 Ω termination and common-mode choke; supports CAN-FD bit rates up to 5 Mbps. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | 32-channel 12-bit SAR ADC with 1 Msps throughput; supports hardware-triggered conversions via PDB or LPIT. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable architecture | Integrated System MPU, ECC on flash/SRAM, CRC module, and dual-watchdog (WDOG + EWM) enable ISO 26262-compliant system design. |
| Flexible low-power operation | Five power modes with sub-µA VLPS current; LPTMR and LPIT provide wake-up from deep sleep with <1 µs latency. |
| Hardware-accelerated security | CSEc implements SHE v3.1 functions (AES-128, SHA-256, RNG, key vault) - but requires explicit mode switch from HSRUN to RUN before execution. |
| Configurable mixed-signal peripherals | Dual 12-bit ADCs (32 ch total), CMP with 8-bit DAC, and PDB enable closed-loop battery monitoring and analog sensor conditioning. |
| Protocol-flexible I/O | FlexIO module supports UART, SPI, I2C, LIN, PWM, and I2S emulation on dedicated pins - reducing BOM count in multi-protocol gateways. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144HAT0VLFR | 2 MB flash, 256 KB SRAM, two FlexCAN modules, 100-pin LQFP package | Supports higher integration density for multi-bus gateways requiring redundant CAN paths and larger OTA image storage | Select when >512 KB flash or second CAN-FD channel is required; same core, peripherals, and software compatibility as FS32K142HAT0VLFR |
| FS32K118LAT0VLFR | Arm Cortex-M0+, 256 KB flash, 32 KB SRAM, no CSEc, 48-pin LQFP, 48 MHz max | Targeted at cost-sensitive LIN nodes or simple sensor interfaces without security or high-speed compute needs | Choose for non-safety, low-compute applications where CSEc, HSRUN mode, or CAN-FD are unnecessary - reduces BOM and layout complexity |
Compared with FS32K142HAT0VLFR, FS32K144HAT0VLFR offers scalable memory and I/O for future-proofing, while FS32K118LAT0VLFR trades performance and security for lower cost and footprint - neither is pin-compatible, but both share the S32K SDK and toolchain.

FAQ
What is the maximum operating frequency of the FS32K142HAT0VLFR and under what conditions?
The FS32K142HAT0VLFR achieves 112 MHz in HSRUN mode, enabled only when voltage is ≥2.7 V and ambient temperature is ≤105 °C. In RUN mode, it operates at 80 MHz - which is required for CSEc security operations and EEPROM emulation, as HSRUN mode disables these functions per silicon design.
Does the FS32K142HAT0VLFR support CAN-FD, and how many CAN interfaces does it include?
Yes, the FS32K142HAT0VLFR includes one FlexCAN module with full ISO 11898-1 CAN-FD support, enabling data rates up to 5 Mbps and payloads up to 64 bytes. It does not include a second CAN controller - that feature is reserved for FS32K144/146/148 variants per the S32K1xx feature comparison table.
What package type and pin count does the FS32K142HAT0VLFR use?
The FS32K142HAT0VLFR uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This matches the "LH" code in its part number and is pin-compatible with other S32K14x devices in the same package variant, per NXP's documentation.
Can CSEc cryptographic operations be executed in HSRUN mode on the FS32K142HAT0VLFR?
No. CSEc (Cryptographic Services Engine) operations - including AES encryption, SHA hashing, and key provisioning - are explicitly prohibited in HSRUN mode (112 MHz) on the FS32K142HAT0VLFR. The device must be switched to RUN mode (80 MHz) before initiating any CSEc command, as confirmed in multiple notes across the datasheet.
What is the flash and SRAM configuration of the FS32K142HAT0VLFR?
The FS32K142HAT0VLFR integrates 512 KB of ECC-protected program flash memory and 64 KB of ECC-protected SRAM. It also includes 4 KB of FlexRAM usable as additional SRAM or EEPROM emulation, and 64 KB of FlexNVM (data flash) - though FlexNVM usage is limited by CSEc/EEPROM write constraints in HSRUN mode.
