Product details
Overview
FS32K142HRT0VLHR from NXP Semiconductors is an automotive-grade Arm® Cortex-M4F microcontroller designed for real-time control in body electronics, powertrain gateways, and chassis modules. It delivers 112 MHz HSRUN performance, 256 KB flash with ECC, 64 KB SRAM, -40 °C to 105 °C ambient operation, and integrated CSEc security engine - enabling secure boot and cryptographic acceleration in ASIL-B–capable systems.
For engineers reviewing the FS32K142HRT0VLHR datasheet, FS32K142HRT0VLHR pinout, FS32K142HRT0VLHR application, or FS32K142HRT0VLHR equivalent, this page provides verified technical context, validated pin-level design meaning, confirmed safety-critical peripheral support (FlexCAN with CAN-FD, LPIT, RTC), and precise alternative part comparisons - all aligned to the S32K1xx Rev. 15 datasheet and orderable part number specifications.
Technical Context
The FS32K142HRT0VLHR implements a dual-core-capable architecture with Arm Cortex-M4F core executing at up to 112 MHz in HSRUN mode and supporting IEEE-754 single-precision FPU, DSP instructions, and NVIC with configurable priority levels. Its memory subsystem includes 256 KB program flash with ECC, 64 KB SRAM with ECC, and 4 KB FlexRAM usable as EEPROM emulation or SRAM.
Power management integrates PMC with five operational modes (HSRUN, RUN, STOP, VLPR, VLPS), where HSRUN enables maximum performance but restricts CSEc and EEPROM operations - requiring transition to 80 MHz RUN mode for secure writes. Clocking supports SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M4F with FPU and DSP extensions - enables deterministic real-time control with floating-point math and signal processing in motor control or sensor fusion. |
| Max Frequency | 112 MHz in HSRUN mode - delivers 140 DMIPS for high-throughput control loops; requires voltage ≥2.7 V and ambient ≤105 °C. |
| Flash / SRAM | 256 KB program flash + 64 KB SRAM, both with ECC - ensures functional safety compliance (ASIL-B) by detecting/correcting single-bit errors in critical memory regions. |
| Operating Temp | -40 °C to +105 °C (V-grade) - qualified for under-hood and body-control applications without derating in automotive environments. |
| Security | Cryptographic Services Engine (CSEc) with SHE-compliant functions - supports AES-128, SHA-256, RNG, and secure key storage; requires RUN mode (80 MHz) for execution. |
| Peripherals | 2× FlexCAN (1 with CAN-FD), 3× LPUART/LIN, 3× LPSPI, 2× LPI2C, 8× FlexTimer channels, 12-bit ADC (32-channel), LPIT, RTC - targets gateway, actuator, and sensor node integration. |
| Package | 64-pin LQFP (LH suffix) - provides 58 GPIOs with interrupt capability, compatible with standard automotive PCB assembly and thermal management. |
Pinout & Package
FS32K142HRT0VLHR is housed in a 64-pin LQFP package (10 × 10 mm, 0.5 mm pitch), optimized for automotive ECU layouts with thermal pad exposure and robust mechanical stability across temperature cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply inputs | Separate digital/analog domains with tight ±0.1 V differential tolerance; require local decoupling per AN5032 to maintain ADC accuracy and noise immunity. |
| RESET_B | Active-low reset input | Asynchronous reset assertion forces full system initialization; must be held low ≥100 ns after VDD stabilizes to ensure reliable boot sequence. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Two-pin debug port supporting JTAG/SWD protocols; enables non-intrusive trace, breakpoint, and memory access during development and field diagnostics. |
| CAN0_TX / CAN0_RX | FlexCAN channel 0 differential I/O | Direct connection to external CAN transceiver; supports ISO 11898-1 physical layer and CAN-FD data rates up to 5 Mbps in FD mode. |
| ADC0_SE0 – ADC0_SE31 | Analog input channels | 32 dedicated pins mapped to 12-bit SAR ADC module; support simultaneous sampling via hardware triggers from LPIT or FlexTimer for synchronized sensor acquisition. |
Key Features
| Feature | Design Value |
|---|---|
| HSRUN + RUN dual-frequency operation | Enables dynamic performance scaling: 112 MHz for time-critical control, 80 MHz for secure CSEc/EEPROM operations - eliminating need for external co-processor. |
| ECC on flash and SRAM | Hardware-implemented error correction detects and corrects single-bit errors and detects double-bit errors - required for ISO 26262 ASIL-B compliance in safety-critical firmware storage. |
| FlexCAN with CAN-FD support | One FlexCAN module supports CAN-FD protocol (up to 5 Mbps data phase); enables high-bandwidth communication in modern vehicle networks without protocol translation overhead. |
| Low-power timer suite | LPIT (4-channel), LPTMR, and RTC provide hierarchical wake-up sources - allowing deep-sleep current <10 µA while maintaining precise timing for periodic sensor polling or CAN bus monitoring. |
| CSEc cryptographic engine | Dedicated hardware accelerator implementing SHE v1.1 functions (AES-128, SHA-256, HMAC, RNG) - offloads CPU, reduces boot time, and prevents software-side side-channel leakage of keys. |
Applications
| Body Control Module (BCM) | Powertrain Gateway |

FAQ
What is the maximum operating frequency of the FS32K142HRT0VLHR and under what conditions?
The FS32K142HRT0VLHR achieves 112 MHz in HSRUN mode, supported across its full -40 °C to +105 °C ambient range and 2.7–5.5 V supply. This frequency requires the SPLL clock source and is only valid in HSRUN mode; CSEc or EEPROM operations must be performed in 80 MHz RUN mode per the S32K1xx datasheet Rev. 15 section 1.1.
Does the FS32K142HRT0VLHR support CAN-FD, and how many channels are available?
Yes, the FS32K142HRT0VLHR includes two FlexCAN modules, with one supporting CAN-FD (ISO 11898-1) up to 5 Mbps data phase. The second FlexCAN channel operates in classical CAN mode. Both are accessible in the 64-pin LQFP package, with dedicated TX/RX pins routed to separate CAN transceivers.
What memory protection features does the FS32K142HRT0VLHR implement for functional safety?
The FS32K142HRT0VLHR implements NXP's system MPU at the Crossbar Switch level - enforcing memory access rights per master (Core, DMA, Ethernet). It also includes ECC on 256 KB flash and 64 KB SRAM, CRC module, internal WDOG, and external EWM - collectively supporting ISO 26262 ASIL-B compliance as documented in the S32K1xx datasheet Rev. 15 section 1.1.
Can the FS32K142HRT0VLHR operate in extended temperature environments beyond 105 °C?
No - the FS32K142HRT0VLHR is V-grade and rated for -40 °C to +105 °C ambient operation. For 150 °C operation, NXP offers the S32K142W series (e.g., FS32K142WRT0WLHR), which uses a different wafer fab process and requires 3.13–5.5 V supply - not interchangeable with FS32K142HRT0VLHR.
What debug interfaces are supported on the FS32K142HRT0VLHR?
The FS32K142HRT0VLHR supports Serial Wire Debug (SWD) via SWD_CLK and SWD_IO pins, compliant with ARM CoreSight standards. It includes Debug Watchpoint and Trace (DWT), Instrumentation Trace Macrocell (ITM), and Flash Patch and Breakpoint (FPB) units - enabling real-time trace, non-intrusive breakpoints, and memory patching during development and field diagnostics.
