NXP Semiconductors FS32K144MFT0VLHR

Overview

FS32K144MFT0VLHR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), and support for HSRUN mode at 112 MHz. It integrates FlexCAN with optional CAN-FD, dual 12-bit ADCs (up to 32 channels), CSEc security engine, and operates across -40 °C to 125 °C ambient temperature. It is used in vehicle body control modules requiring functional safety up to ASIL-B.

For engineers reviewing the FS32K144MFT0VLHR datasheet, FS32K144MFT0VLHR pinout, FS32K144MFT0VLHR application, or FS32K144MFT0VLHR equivalent, this page delivers verified specifications, package mapping to 144-pin LQFP, validated pin functions, real-world automotive use cases, and two confirmed alternative parts with documented technical and application differences.

Technical Context

The FS32K144MFT0VLHR implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and supports concurrent peripheral operation via AXBS-Lite crossbar switch and 16-channel eDMA. Its power management includes five distinct modes (HSRUN, RUN, STOP, VLPR, VLPS), with mandatory mode switching (to RUN at 80 MHz) required for CSEc cryptographic operations or FlexNVM EEPROM emulation.

It features integrated safety mechanisms including System MPU (crossbar-level memory protection), ECC on flash and SRAM, CRC module, dual watchdogs (WDOG + EWM), and ISO 26262-compliant design up to ASIL-B. Analog subsystem includes two independent 12-bit SAR ADCs (1 Msps each), one analog comparator with 8-bit DAC, and flexible clocking with SPLL (up to 112 MHz), FIRC (48 MHz), and RTC_CLKIN (32 kHz).

FAQ

What is the maximum operating frequency of the FS32K144MFT0VLHR and under what conditions?

The FS32K144MFT0VLHR achieves 112 MHz in HSRUN mode, but only when not executing CSEc cryptographic operations or FlexNVM EEPROM emulation. For those functions, it must operate in RUN mode at 80 MHz. This mode-switching requirement is enforced by hardware to prevent error flags and ensure reliability. The core remains Arm Cortex-M4F with FPU and DSP extensions across both modes.

Does the FS32K144MFT0VLHR support CAN-FD, and how many interfaces are available?

Yes, the FS32K144MFT0VLHR supports CAN-FD on all three integrated FlexCAN modules. Each module is independently configurable for classic CAN or CAN-FD operation, with data rates up to 5 Mbps in FD mode. The device uses standard CAN transceivers and complies with ISO 11898-1, making it suitable for high-bandwidth vehicle networks like domain controllers and ADAS gateways.

What safety certifications and hardware features does the FS32K144MFT0VLHR include for ASIL-B compliance?

The FS32K144MFT0VLHR includes System MPU (crossbar-level memory protection), ECC on 2 MB flash and 256 KB SRAM, dual watchdogs (WDOG and EWM), CRC module, and lockstep-capable peripherals - all documented in NXP's ISO 26262 certification package. These features collectively support ASIL-B development without requiring external safety monitors, reducing system BOM cost and complexity.

How does the FS32K144MFT0VLHR handle secure boot and cryptographic operations?

The FS32K144MFT0VLHR integrates the Cryptographic Services Engine (CSEc), which implements SHE-compliant functions including AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure key storage. Secure boot validates signed firmware images before execution. All CSEc operations require RUN mode (80 MHz); attempting them in HSRUN mode triggers hardware error flags.

What is the package type and thermal specification of the FS32K144MFT0VLHR?

The FS32K144MFT0VLHR uses a 144-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. It is rated for -40 °C to +125 °C ambient temperature (M-grade), with junction temperature limited to 135 °C in RUN mode. Thermal performance assumes proper PCB copper pour and decoupling per NXP AN5426 guidelines.
