NXP Semiconductors FS32K144UAT0VLLT

Overview

FS32K144UAT0VLLT 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 2 MB program flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +105 °C ambient operation. Used in body control modules, battery management systems, and motor control units requiring ASIL-B compliance.

For engineers reviewing the FS32K144UAT0VLLT datasheet, FS32K144UAT0VLLT pinout, FS32K144UAT0VLLT application, or FS32K144UAT0VLLT equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain-ready availability details - all grounded in the official S32K1xx Rev. 15 datasheet and orderable part number list.

Technical Context

The FS32K144UAT0VLLT implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and integrated Single Precision FPU, DSP extensions, and configurable NVIC. Its memory subsystem includes ECC-protected 2 MB flash, 256 KB SRAM, and 64 KB FlexNVM for EEPROM emulation - with CSEc security operations restricted to RUN mode (80 MHz) due to hardware arbitration constraints.

Peripheral integration includes three FlexCAN modules (CAN-FD capable), three LPSPI, two LPI2C, three LPUART/LIN, eight FlexTimer modules (64 PWM/IC/OC channels), and a 12-bit ADC with up to 32 inputs per module. Power management supports five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), with PMC-controlled clock gating and voltage scaling aligned to ISO 26262 ASIL-B requirements.

FAQ

What is the maximum operating frequency of the FS32K144UAT0VLLT?

The FS32K144UAT0VLLT supports up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. The 112 MHz operation requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C; CSEc or EEPROM operations must be executed in RUN mode (80 MHz) per hardware restriction documented in the S32K1xx datasheet Rev. 15.

Does the FS32K144UAT0VLLT include hardware security features?

Yes, the FS32K144UAT0VLLT integrates the Cryptographic Services Engine (CSEc) compliant with SHE v1.1, supporting AES-128, SHA-256, RNG, and secure key storage. Security operations require switching from HSRUN to RUN mode (80 MHz), and the device includes a 128-bit unique ID and system MPU for memory protection.

Which package type does the FS32K144UAT0VLLT use?

The FS32K144UAT0VLLT uses a 144-pin LQFP package (code LL), with 0.5 mm pitch and 20 × 20 mm body size. It is pin-to-pin compatible with other S32K14x devices in the same 144-pin LQFP variant, enabling hardware reuse across performance tiers.

Can the FS32K144UAT0VLLT support CAN-FD communication?

Yes, the FS32K144UAT0VLLT includes three FlexCAN modules, each supporting ISO 11898-1 CAN-FD with data rates up to 5 Mbps and payloads up to 64 bytes. CAN-FD functionality is enabled by default and requires no external transceivers beyond standard bus termination.

What is the flash and RAM configuration of the FS32K144UAT0VLLT?

The FS32K144UAT0VLLT integrates 2 MB of program flash memory with ECC, 256 KB of SRAM with ECC, 64 KB of FlexNVM for data flash/EEPROM emulation, and 4 KB of FlexRAM usable as SRAM or EEPROM. All memory blocks implement error correction to meet automotive reliability requirements.
