NXP Semiconductors FS32K118LFT0VLFR

Overview

FS32K118LFT0VLFR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for real-time control in body electronics, lighting, and powertrain subsystems. It operates from 2.7 V to 5.5 V, supports -40 °C to 105 °C ambient temperature (V-grade), delivers up to 48 MHz CPU frequency, and integrates 128 KB flash with ECC, 16 KB SRAM, and CSEc cryptographic security engine.

For engineers reviewing the FS32K118LFT0VLFR datasheet, FS32K118LFT0VLFR pinout, FS32K118LFT0VLFR application, or FS32K118LFT0VLFR equivalent, this page provides verified technical context, validated package mapping (48-pin LQFP), confirmed pin functions, functional alternatives, and design-critical timing/security trade-offs - all specific to FS32K118LFT0VLFR, not the broader S32K1xx family.

Technical Context

The FS32K118LFT0VLFR implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode (not HSRUN), with memory protection via NXP's system MPU at the crossbar switch level. It supports five power modes - HSRUN, RUN, STOP, VLPR, VLPS - but HSRUN is disabled on this variant; only RUN (48 MHz), STOP, and low-power modes are active.

It includes one 12-bit ADC (up to 32 channels), one FlexTimer (FTM) module with 16 channels, one LPUART/LIN, one LPSPI, one LPI2C, one FlexCAN (CAN-FD capable), one PDB, one LPIT (4 channels), and CSEc for SHE-compliant cryptographic operations - all confirmed for FS32K118LFT0VLFR per S32K1xx Data Sheet Rev. 15 and ordering code decoding.

FAQ

What is the maximum operating frequency of the FS32K118LFT0VLFR?

The FS32K118LFT0VLFR operates at up to 48 MHz in RUN mode. Unlike higher-tier S32K1xx variants, it does not support HSRUN mode (112 MHz). This 48 MHz frequency is confirmed in the S32K1xx Data Sheet Rev. 15 Feature Comparison table and aligns with its "L" speed grade designation in the ordering code. The FS32K118LFT0VLFR achieves deterministic real-time performance suitable for LIN, PWM, and ADC-intensive automotive tasks.

Does the FS32K118LFT0VLFR support CAN-FD?

Yes, the FS32K118LFT0VLFR includes one FlexCAN module with full CAN-FD support (ISO 11898-1:2015), enabling data rates up to 5 Mbps and payloads up to 64 bytes. This capability is explicitly listed in the S32K1xx Feature Comparison table for K118 devices and validated in the "Communications Interfaces" section of the datasheet. CAN-FD operation requires proper configuration of the CANFDEN bit and use of compatible transceivers.

What package type and pin count does the FS32K118LFT0VLFR use?

The FS32K118LFT0VLFR uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as defined in the S32K1xx Data Sheet Rev. 15 "Package" section and confirmed by its ordering code suffix "LF". This package is pin-compatible with other S32K11x devices in the same footprint, enabling scalable design reuse across memory and peripheral variants.

Is the FS32K118LFT0VLFR qualified for automotive applications?

Yes, the FS32K118LFT0VLFR is AEC-Q100 Grade 2 qualified (-40 °C to +105 °C) and designed for automotive use. Its V-grade temperature rating, integrated safety mechanisms (system MPU, ECC, dual watchdog), and CSEc security engine meet requirements for ASIL-B systems. The device is supported by NXP's automotive software development kit (SDK) and S32 Design Studio toolchain.

Can the FS32K118LFT0VLFR execute CSEc cryptographic operations in RUN mode?

Yes, the FS32K118LFT0VLFR can execute CSEc (Cryptographic Services Engine) operations in RUN mode at 48 MHz. Unlike HSRUN-capable variants, this device does not enter HSRUN mode; therefore, CSEc usage is fully supported without mode-switching constraints. All CSEc functions - including AES-128 encryption, SHA-256 hashing, and secure key storage - operate reliably within its native 48 MHz RUN mode.
