Product details
Overview
FS32K142HAT0VLHR from NXP Semiconductors is an automotive-grade 32-bit Arm® Cortex-M4F microcontroller designed for real-time control in safety-critical ECUs. It operates at up to 112 MHz (HSRUN mode), features 256 KB flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +105 °C ambient operation. Its integrated CSEc security engine, dual 12-bit ADCs (up to 32 channels), and three FlexCAN modules with optional CAN-FD make it suitable for body control modules and gateway applications.
For engineers reviewing the FS32K142HAT0VLHR datasheet, FS32K142HAT0VLHR pinout, FS32K142HAT0VLHR application, or FS32K142HAT0VLHR equivalent, key selection considerations include HSRUN/RUN mode switching constraints for CSEc/EEPROM operations, 100-pin LQFP package compatibility, ASIL-B capable power management, and verified FlexCAN/CAN-FD timing compliance per ISO 11898-1.
Technical Context
The FS32K142HAT0VLHR implements a dual-core architecture with Arm Cortex-M4F as primary execution core and M0+ for low-power background tasks, sharing AXBS-Lite crossbar and system MPU for memory protection. Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with configurable gating per peripheral domain.
Power management includes five operational modes-HSRUN, RUN, STOP, VLPR, VLPS-with PMC-enforced transitions; CSEc cryptographic operations and EEPROM emulation are restricted to RUN mode (80 MHz) due to hardware arbitration conflict in HSRUN mode. Memory subsystem uses ECC on all flash and SRAM blocks, with QuadSPI supporting HyperBus™ for external code/data expansion.
Key Specifications

Pinout & Package
FS32K142HAT0VLHR is housed in a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow NXP's standardized S32K14x I/O multiplexing scheme, supporting flexible peripheral routing via TRGMUX and IO PORT controllers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O robustness across voltage transients. |
| RESET_B | Active-low reset input | Accepts external watchdog or power-on reset signals; internal pull-up ensures safe startup if left unconnected. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debug, trace, and flash programming; requires 10 kΩ pull-up on SWD_IO for reliable JTAG/SWD detection. |

Key Features
| Feature | Design Value |
|---|---|
| System MPU | NXP's crossbar-level memory protection unit enforces access rights per master (core, DMA, Ethernet), enabling ASIL-B partitioning without Arm Core MPU. |

FAQ
What is the maximum operating frequency of the FS32K142HAT0VLHR and under which conditions?
The FS32K142HAT0VLHR achieves up to 112 MHz in HSRUN mode, validated across -40 °C to +105 °C ambient temperature with 2.7–5.5 V supply. This frequency requires SPLL configuration and is not available for CSEc or EEPROM operations, which must execute at 80 MHz in RUN mode per hardware arbitration rules documented in the S32K1xx Data Sheet Rev. 15.
Does the FS32K142HAT0VLHR support CAN FD, and what are the electrical requirements?
Yes, the FS32K142HAT0VLHR includes three FlexCAN modules that support CAN FD per ISO 11898-1, with bit rates up to 5 Mbps in FD mode. It requires external CAN transceivers compliant with ISO 11898-2/5; no internal termination or biasing is provided. The FS32K142HAT0VLHR itself handles protocol framing, error handling, and RAM-based message buffering without CPU intervention.
How does the CSEc security engine in the FS32K142HAT0VLHR operate, and what cryptographic functions does it support?
The FS32K142HAT0VLHR integrates the Cryptographic Services Engine (CSEc), compliant with the Secure Hardware Extension (SHE) specification. It supports AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure boot verification. All CSEc operations must occur in RUN mode (80 MHz); attempting them in HSRUN mode triggers error flags and requires explicit mode transition.
What is the purpose of the FlexRAM in the FS32K142HAT0VLHR, and how is it configured?
The FS32K142HAT0VLHR includes 4 KB of FlexRAM that can be dynamically allocated as either general-purpose SRAM or EEPROM emulation storage. Configuration is controlled via FTFC_FCCOB registers; when used as EEPROM, it provides wear-leveling and atomic write/erase cycles without external components. This FlexRAM resides in the same memory map as main SRAM and benefits from ECC protection.
Is the FS32K142HAT0VLHR pin-compatible with other S32K14x devices in the same package?
Yes, the FS32K142HAT0VLHR in 100-pin LQFP is pin-to-pin compatible with all other S32K14x family members offered in the same 100-pin LQFP package, including FS32K144HAT0VLHR and FS32K146HAT0VLHR. Peripheral availability depends on pin multiplexing configuration and is documented in the S32K1xx Reference Manual IO Signal Description sheets.
