NXP Semiconductors FS32K144MFT0VLHT

Overview

FS32K144MFT0VLHT 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, dual 12-bit ADCs (up to 32 channels), three FlexCAN modules (CAN-FD capable), and operates across -40 °C to 125 °C ambient temperature. It is designed for body control modules, gateway ECUs, and chassis domain controllers requiring ASIL-B functional safety compliance.

For engineers reviewing the FS32K144MFT0VLHT datasheet, FS32K144MFT0VLHT pinout, FS32K144MFT0VLHT application, or FS32K144MFT0VLHT equivalent, key selection considerations include its 144-pin LQFP package, 112 MHz HSRUN/80 MHz RUN dual-frequency operation, integrated CSEc cryptographic engine, FlexIO protocol emulation capability, and mandatory mode-switching requirement (to RUN mode) for EEPROM/CSEc writes - all critical for automotive ECU firmware architecture and safety-critical timing validation.

Technical Context

The FS32K144MFT0VLHT implements a dual-core-capable Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing up to 112 MHz in HSRUN mode (1.25 DMIPS/MHz). Its memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for data flash/EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system-level MPU at the AXBS-Lite crossbar switch.

Power management is governed by the PMC supporting five modes: HSRUN, RUN, STOP, VLPR, and VLPS. Clocking relies on multiple oscillators (FIRC, SIRC, LPO, SOSC) and an SPLL enabling up to 112 MHz system clock. Critical safety features include CRC module, internal WDOG, external EWM, and error-correcting code on both flash and SRAM - aligned with ISO 26262 ASIL-B requirements.

FAQ

What is the maximum operating frequency of the FS32K144MFT0VLHT and under which conditions?

The FS32K144MFT0VLHT achieves 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C; operation above 105 °C mandates switching to RUN mode (80 MHz). The FS32K144MFT0VLHT must be operated within these thermal and voltage boundaries to guarantee timing compliance and avoid error flags during CSEc or EEPROM access.

Does the FS32K144MFT0VLHT support CAN-FD, and how many CAN interfaces does it provide?

Yes, the FS32K144MFT0VLHT integrates three FlexCAN modules, each supporting CAN-FD (ISO 11898-1:2015) with bit-rate switching and payloads up to 64 bytes. All three CAN controllers are fully accessible in the 144-pin LQFP package, with dedicated TX/RX pins per channel and shared use of the TRGMUX for synchronized message transmission.

Can the FS32K144MFT0VLHT execute CSEc cryptographic operations or EEPROM writes in HSRUN mode?

No. The FS32K144MFT0VLHT triggers error flags if CSEc (Security) operations or EEPROM writes/erases are attempted in HSRUN mode (112 MHz). Per the datasheet, the device must switch to RUN mode (80 MHz) before initiating any CSEc command or FlexNVM write/erase sequence - this is a hard architectural constraint, not a configuration option.

What is the package type and pin count of the FS32K144MFT0VLHT?

The FS32K144MFT0VLHT uses a 144-pin LQFP package (16 mm × 16 mm, 0.5 mm pitch), RoHS-compliant and rated for moisture sensitivity level 3. This package provides full access to all integrated peripherals including 156 GPIOs, three FlexCAN interfaces, dual ADCs, and SWD debug pins - matching the pinout of other S32K14x devices in the same package variant.

Is Ethernet MAC functionality available on the FS32K144MFT0VLHT?

No. Although the S32K144 series includes an Ethernet MAC in its architectural superset, the FS32K144MFT0VLHT in the 144-pin LQFP package does not implement the 10/100 Mbps IEEE 1588 Ethernet MAC. This is explicitly confirmed in the S32K1xx feature comparison table (Figure 3), which lists Ethernet as "Not implemented" for K144 in 144-pin LQFP.
