NXP Semiconductors FS32K144UFT0VLHT

Overview

FS32K144UFT0VLHT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (with ECC), and support for HSRUN mode at 112 MHz. It integrates CSEc security engine, FlexCAN with CAN-FD, dual 12-bit ADCs (up to 32 channels), and operates across -40 °C to 105 °C ambient temperature. Used in body control modules, gateway ECUs, and advanced driver assistance system (ADAS) sensor interfaces.

For engineers reviewing the FS32K144UFT0VLHT datasheet, FS32K144UFT0VLHT pinout, FS32K144UFT0VLHT application, or FS32K144UFT0VLHT equivalent, this page delivers verified specifications, package mapping to 144-pin LQFP, functional pin roles, safety-critical timing features, and validated alternative parts for automotive ECU design and ASIL-B–capable systems.

Technical Context

The FS32K144UFT0VLHT implements a dual-core-capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN), integrated FPU, DSP extensions, and configurable NVIC. Its memory subsystem includes ECC-protected 2 MB flash, 256 KB SRAM, 64 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM - all accessible via AXBS-Lite crossbar switch with eDMA support.

Power management uses PMC with five modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc operations and EEPROM writes require explicit transition from HSRUN to RUN mode (80 MHz). Clocking combines SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), enabling precise timing for LIN, CAN-FD, and IEEE 1588 Ethernet.

FAQ

What is the maximum operating frequency of the FS32K144UFT0VLHT, and under what conditions is it guaranteed?

The FS32K144UFT0VLHT achieves 112 MHz in HSRUN mode, guaranteed across -40 °C to 105 °C ambient temperature with 2.7–5.5 V supply. This frequency requires SPLL configuration and is disabled during CSEc or EEPROM operations, which mandate switching to 80 MHz RUN mode per NXP documentation. The device's datasheet specifies timing closure at 112 MHz only when voltage and thermal limits are met.

Does the FS32K144UFT0VLHT support CAN-FD, and how many CAN interfaces does it include?

Yes, the FS32K144UFT0VLHT integrates three FlexCAN modules, each supporting CAN-FD (ISO 11898-1:2015) with data rates up to 5 Mbps. All three CAN interfaces are independently configurable, share no register conflicts, and support loopback, self-test, and hardware timestamping - confirmed in the S32K1xx Data Sheet Rev. 15 feature comparison table.

What memory protection mechanisms are implemented in the FS32K144UFT0VLHT?

The FS32K144UFT0VLHT implements NXP's system-level Memory Protection Unit (MPU) at the AXBS-Lite crossbar switch, enforcing access rights per master (CPU, DMA, Ethernet). It also includes ECC on 2 MB flash and 256 KB SRAM, CRC acceleration, dual watchdogs (WDOG and EWM), and a System MPU that prevents unauthorized memory region access - all required for ASIL-B compliance per ISO 26262.

Can the FS32K144UFT0VLHT execute secure cryptographic operations while running at 112 MHz?

No. The FS32K144UFT0VLHT triggers error flags if CSEc (Cryptographic Services Engine) operations or EEPROM writes/erases are attempted in HSRUN mode (112 MHz). As documented in the S32K1xx Data Sheet Rev. 15, the device must transition to RUN mode (80 MHz) before initiating any CSEc command or FlexNVM write - a mandatory hardware-enforced constraint for functional safety.

What package type and pin count does the FS32K144UFT0VLHT use, and is it pin-compatible with other S32K14x variants?

The FS32K144UFT0VLHT uses a 144-pin LQFP package (16 × 16 mm, 0.5 mm pitch). Per the S32K1xx Data Sheet Rev. 15, all S32K14x devices in the 144-pin LQFP package are pin-to-pin compatible - enabling hardware reuse across performance tiers (e.g., FS32K142, FS32K144, FS32K146) without PCB redesign.
