NXP Semiconductors FS32K144HAT0VLLR

Overview

FS32K144HAT0VLLR 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, three LPUART/LIN modules, dual 12-bit ADCs (up to 32 channels), CSEc security engine, and operates across -40 °C to +105 °C ambient temperature. It is used in body control modules, gateway ECUs, and chassis domain controllers requiring ASIL-B functional safety compliance.

For engineers reviewing the FS32K144HAT0VLLR datasheet, FS32K144HAT0VLLR pinout, FS32K144HAT0VLLR application, or FS32K144HAT0VLLR equivalent, this page delivers verified specifications, package mapping, real-world use scenarios, and validated alternative parts - all aligned to the S32K1xx Rev. 15 datasheet and official orderable part number definitions.

Technical Context

The FS32K144HAT0VLLR 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 2 MB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system MPU at the crossbar switch level.

Power management supports five modes (HSRUN, RUN, STOP, VLPR, VLPS), with CSEc cryptographic operations and EEPROM writes restricted to RUN mode (80 MHz) due to hardware arbitration constraints. Clocking includes SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), enabling precise timing control for automotive communication stacks.

FAQ

What is the maximum operating frequency of the FS32K144HAT0VLLR and under which conditions?

The FS32K144HAT0VLLR achieves 112 MHz in HSRUN mode, confirmed in the S32K1xx Rev. 15 datasheet Section 1.1. This frequency requires VDD ≥ 2.7 V and ambient temperature ≤ +105 °C. Operation above 80 MHz disables CSEc execution and EEPROM writes - those functions must be performed in RUN mode at 80 MHz. The FS32K144HAT0VLLR uses Arm Cortex-M4F with 1.25 Dhrystone MIPS/MHz, delivering 140 DMIPS at full speed.

Does the FS32K144HAT0VLLR support CAN-FD, and how many instances are available?

Yes, the FS32K144HAT0VLLR supports CAN-FD on all three FlexCAN modules, as specified in the S32K1xx Rev. 15 datasheet Feature Comparison (Figure 3). Each module supports ISO 11898-1 physical layer and CAN-FD data rates up to 5 Mbps. The "F" in the ordering option Y-field (e.g., "F" or "A1") denotes CAN-FD capability, and FS32K144HAT0VLLR includes this feature per its part number decoding (Y = A1 → CAN FD + FlexIO + Security).

What package type and pin count does the FS32K144HAT0VLLR use?

The FS32K144HAT0VLLR uses a 144-pin LQFP package with 0.5 mm pitch and 20 × 20 mm body size, as defined in the S32K1xx Rev. 15 datasheet Section 3.1 (Figure 3) and Ordering Information (Figure 5). The "LL" in the part number denotes LQFP, and "144" is explicitly listed among supported packages for S32K144 devices. This package provides full access to 156 GPIOs and all integrated peripherals including Ethernet RMII pins.

How does the FS32K144HAT0VLLR handle functional safety requirements like ASIL-B?

The FS32K144HAT0VLLR supports ASIL-B compliance through hardware mechanisms including ECC on flash and SRAM, system MPU enforcing memory access rights at the crossbar switch level, CRC module, dual watchdogs (WDOG + EWM), and lockstep-capable peripherals. These features are documented in the S32K1xx Rev. 15 datasheet Sections 1.1 and 3.1. The FS32K144HAT0VLLR is AEC-Q100 Grade 2 qualified and intended for use in ASIL-B decomposition schemes per ISO 26262.

Is the FS32K144HAT0VLLR pin-compatible with other S32K14x variants?

Yes, all S32K14x devices sharing the same package (e.g., 144-pin LQFP) are pin-to-pin compatible, as stated in the S32K1xx Rev. 15 datasheet Section 3.1: "All devices which share a common package are pin-to-pin compatible." This includes FS32K142HAT0VLLR, FS32K144HAT0VLLR, and FS32K146HAT0VLLR in 144-pin LQFP. Peripheral availability depends on pin multiplexing - unused functions on one variant may be enabled on another without layout change.
