NXP Semiconductors FS32K118BRT0VLHT

Overview

FS32K118BRT0VLHT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 48 MHz, supports -40 °C to 105 °C ambient temperature, integrates 128 KB flash with ECC, 16 KB SRAM, and features CSEc security engine, FlexCAN (1 channel), and LPUART/LIN interfaces.

For engineers reviewing the FS32K118BRT0VLHT datasheet, FS32K118BRT0VLHT pinout, FS32K118BRT0VLHT application, or FS32K118BRT0VLHT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases in automotive subsystems, and two validated alternative parts with functional and application-level distinctions.

Technical Context

The FS32K118BRT0VLHT implements an Arm Cortex-M0+ core with Thumb®-2 ISA, supporting up to 48 MHz operation and 1.25 Dhrystone MIPS/MHz performance. It includes a configurable NVIC, integrated CRC module, and system-level MPU enforcing memory access rights at the crossbar switch level-not via Arm's core-integrated MPU.

Power management is handled by the PMC, enabling five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS); however, HSRUN mode is not supported on this variant-only RUN mode at 48 MHz is active. Security operations (CSEc) and EEPROM emulation require switching to RUN mode, as HSRUN is unavailable per device configuration.

Key Specifications

Pinout & Package

FS32K118BRT0VLHT is housed in a 48-pin LQFP (LH) package with 0.5 mm pitch, exposing VDD/VSS pairs for decoupling, dedicated reset and clock inputs, and multiplexed GPIO supporting LIN, LPUART, LPSPI, and LPI2C peripherals. Pin assignments follow NXP's S32K11x IO Signal Description sheet for 48-pin LQFP.

FAQ

What is the maximum operating frequency of the FS32K118BRT0VLHT?

The FS32K118BRT0VLHT operates at a maximum frequency of 48 MHz in RUN mode. Unlike higher-tier S32K1xx variants, it does not support HSRUN mode (112 MHz). This 48 MHz speed is fully specified across its -40 °C to +105 °C operating range and aligns with LIN and CAN timing budgets for automotive body electronics. The FS32K118BRT0VLHT uses the Arm Cortex-M0+ core, which delivers deterministic real-time performance at this clock rate.

Does the FS32K118BRT0VLHT support CAN-FD?

No, the FS32K118BRT0VLHT includes one FlexCAN module compliant with CAN 2.0B only and does not support CAN-FD. Its CAN controller is limited to 1 Mbps classical CAN operation. This is consistent with its positioning in cost-optimized body electronics applications where legacy CAN bandwidth suffices. For CAN-FD capability, engineers should consider FS32K142 or higher variants - the FS32K118BRT0VLHT itself has no CAN-FD hardware or firmware support.

What package type and pin count does the FS32K118BRT0VLHT use?

The FS32K118BRT0VLHT uses a 48-pin LQFP package (code "LH") with 0.5 mm pitch. This package is explicitly listed in the S32K1xx datasheet as supported for the S32K118 variant and matches the pinout defined in NXP's IO Signal Description document for 48-pin LQFP. It provides 36 GPIOs (including multiplexed functions), dedicated power/ground pairs, and full peripheral signal routing for LIN, CAN, SPI, and ADC interfaces.

Is the FS32K118BRT0VLHT qualified for automotive use?

Yes, the FS32K118BRT0VLHT is AEC-Q100 qualified for Grade 2 (-40 °C to +105 °C ambient), supports ISO 26262 up to ASIL-B, and includes safety mechanisms such as ECC on flash and SRAM, system-level MPU, CRC module, and dual watchdogs (WDOG and EWM). Its design targets automotive body electronics, junction boxes, and door modules where functional safety and environmental robustness are mandatory - all confirmed in the official S32K1xx datasheet Rev. 15.

How much on-chip flash and SRAM does the FS32K118BRT0VLHT include?

The FS32K118BRT0VLHT integrates 128 KB of program flash memory with end-to-end ECC protection and 16 KB of SRAM also protected by ECC. It does not include FlexNVM or FlexRAM - those features are reserved for S32K14x devices. The 128 KB flash is sufficient for complex LIN gateway or BCM firmware with bootloader, application, and secure update partitions; the 16 KB ECC SRAM ensures safe runtime data handling in safety-critical contexts.
