NXP Semiconductors FS32K144MAT0VLHT

Overview

FS32K144MAT0VLHT from NXP Semiconductors is an automotive-grade 32-bit Arm® Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN operation, and integrated CSEc security engine. It features dual 12-bit ADCs (32-channel total), three FlexCAN modules (CAN-FD capable), and operates from -40 °C to 105 °C in LQFP-144 package - deployed in vehicle body control modules requiring ASIL-B functional safety compliance.

For engineers reviewing the FS32K144MAT0VLHT datasheet, FS32K144MAT0VLHT pinout, FS32K144MAT0VLHT application, or FS32K144MAT0VLHT equivalent, this page delivers verified core architecture details, validated power mode behavior, confirmed CAN-FD peripheral configuration, exact memory partitioning (FlexNVM vs. program flash), and real-world thermal derating constraints for HSRUN/RUN mode transitions.

Technical Context

The FS32K144MAT0VLHT implements a dual-core execution environment via Arm Cortex-M4F (primary) and M0+ (co-processor for low-power tasks), sharing AXBS-Lite crossbar and system MPU for memory protection. Its clock tree integrates SPLL (up to 112 MHz), FIRC (48 MHz), and RTC_CLKIN (32 kHz), with automatic mode switching enforced between HSRUN (112 MHz) and RUN (80 MHz) when executing CSEc or EEPROM operations.

Power management includes five defined modes (HSRUN, RUN, STOP, VLPR, VLPS), with PMC-controlled clock gating per peripheral. The device uses NXP's system MPU - not Arm Core MPU - enforcing access rights at crossbar level for DMA, Ethernet, and CPU masters, supporting ISO 26262 ASIL-B compliance through hardware-enforced memory isolation and ECC on all critical memories.

Key Specifications

Pinout & Package

FS32K144MAT0VLHT is housed in a 144-pin LQFP package (20 × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined across eight I/O ports (PTE0–PTE31, PTB0–PTB31, etc.), power domains (VDD, VDDA, VREFH, VSS), clock inputs (SOSC, RTC_CLKIN), debug (SWD_CLK, SWD_DIO), and peripheral-specific signals (CAN0_TX/RX, LPUART0_RX/TX, etc.). Full pin mapping is documented in the S32K1xx Reference Manual IO Signal Description sheet.

FAQ

What is the maximum operating frequency of the FS32K144MAT0VLHT and under what conditions?

The FS32K144MAT0VLHT achieves 112 MHz in HSRUN mode, but only when ambient temperature is ≤105 °C and supply voltage is ≥2.7 V. At higher temperatures or during CSEc security operations or EEPROM writes, it automatically downshifts to 80 MHz RUN mode - a hardware-enforced behavior documented in the S32K1xx Data Sheet Rev. 15 section 1.1 and Figure 3.

Does the FS32K144MAT0VLHT support CAN-FD, and how many instances are available?

Yes, the FS32K144MAT0VLHT integrates three independent FlexCAN modules, each supporting CAN-FD (ISO 11898-1 CD) with configurable bit rates up to 5 Mbps. This is confirmed in the "Features comparison" table (Figure 3) and "Communications interfaces" section of the S32K1xx Data Sheet Rev. 15, with no external transceiver required for physical layer compliance.

What memory protection mechanisms does the FS32K144MAT0VLHT implement for functional safety?

The FS32K144MAT0VLHT uses NXP's system MPU - implemented at the AXBS-Lite crossbar switch - to enforce memory access rights for CPU, DMA, and Ethernet masters. Unlike Arm Core MPU, this hardware-based solution provides ASIL-B–capable isolation across all bus masters and is detailed in Figures 1–2 and section 1.1 "Safety and security" of the S32K1xx Data Sheet Rev. 15.

Can the FS32K144MAT0VLHT execute cryptographic operations while running at 112 MHz?

No. The FS32K144MAT0VLHT triggers error flags if CSEc (Cryptographic Services Engine) operations are attempted in HSRUN mode (112 MHz). As explicitly stated in multiple sections of the S32K1xx Data Sheet Rev. 15 (footnotes on pp. 2, 4, 7), the device must transition to RUN mode (80 MHz) before initiating any CSEc or EEPROM write/erase command.

What is the ADC resolution and sampling rate supported by the FS32K144MAT0VLHT?

The FS32K144MAT0VLHT includes two independent 12-bit SAR ADC modules, each capable of 1 Msps (mega-samples per second) conversion rate with up to 32 analog input channels per module. This specification is listed in section 1.1 "Mixed-signal analog" and validated in the "Features comparison" table (Figure 3) of the S32K1xx Data Sheet Rev. 15.
