Product details
Overview
FS32K118LIT0VLFR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. 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 engine - deployed in vehicle door modules, lighting controllers, and battery management subsystems.
For engineers reviewing the FS32K118LIT0VLFR datasheet, FS32K118LIT0VLFR pinout, FS32K118LIT0VLFR application, or FS32K118LIT0VLFR equivalent, this page provides verified technical context, validated package mapping (48-pin LQFP), confirmed low-power peripheral support (LPUART/LPSPI/LPI2C), and real-world functional trade-offs versus alternative S32K1xx variants - all aligned to ISO 26262 ASIL-B capable system design.
Technical Context
The FS32K118LIT0VLFR implements an Arm Cortex-M0+ core without FPU, operating at up to 48 MHz in RUN mode, with dedicated low-power clock sources (FIRC, SIRC, LPO) and a System PLL supporting flexible frequency synthesis. Its memory subsystem includes 128 KB ECC-protected program flash, 16 KB SRAM, and 4 KB FlexRAM usable as SRAM or EEPROM emulation.
Peripheral integration centers on functional safety: one FlexCAN module (CAN FD capable), three LPUART/LIN interfaces with DMA, two LPSPI modules, one LPI2C, a 12-bit ADC with 16-channel input, and safety mechanisms including System MPU, CRC, WDOG, EWM, and CSEc - all qualified for ASIL-B compliance per ISO 26262.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LIT0VLFR | 128 KB flash, 16 KB SRAM, same 48-pin LQFP package, but only 256 KB max flash option and no FlexCAN FD support. | Limited to LIN-only communication; lacks CAN FD required for advanced ADAS gateway functions. | Select when cost-sensitive body control applications do not require CAN FD bandwidth or additional flash for OTA updates. |
| FS32K142LIT0VLFR | Arm Cortex-M4F core, 80 MHz, 256 KB flash, 32 KB SRAM, dual FlexCAN with FD, and Ethernet MAC - larger 64-pin LQFP package. | Supports time-sensitive networking (IEEE 1588) and higher-throughput domain controllers; requires PCB redesign for pin count and layout. | Choose for next-generation vehicle architectures needing ASIL-B + ASIL-C hybrid safety domains and multi-protocol gateway functionality. |
Compared with FS32K116LIT0VLFR, FS32K118LIT0VLFR adds FlexCAN FD and CSEc security - essential for secure ECU-to-ECU messaging. Versus FS32K142LIT0VLFR, it trades M4F performance and Ethernet for lower cost, smaller footprint, and identical pinout compatibility within the 48-pin LQFP family.

FAQ
What is the maximum operating frequency of the FS32K118LIT0VLFR?
The FS32K118LIT0VLFR operates at up to 48 MHz in RUN mode using the FIRC or SOSC oscillator with PLL. It does not support HSRUN mode (112 MHz), which is exclusive to M4F-based S32K14x devices. This 48 MHz ceiling ensures thermal stability and power efficiency for body-control applications where deterministic timing outweighs peak throughput.
Does the FS32K118LIT0VLFR support CAN FD?
Yes, the FS32K118LIT0VLFR includes one FlexCAN module with full CAN FD (ISO 11898-1:2015) support, enabling data rates up to 5 Mbps and payloads up to 64 bytes. This capability is confirmed in the S32K1xx Family Data Sheet Rev. 15 feature comparison table and is enabled by default in the device's peripheral configuration registers.
What package type and pin count does the FS32K118LIT0VLFR use?
The FS32K118LIT0VLFR uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), matching the pinout of other S32K11x variants in the same package size. This allows drop-in replacement within the S32K11x family and simplifies board design reuse across multiple vehicle platforms.
Is the FS32K118LIT0VLFR qualified for automotive applications?
Yes, the FS32K118LIT0VLFR is AEC-Q100 Grade 2 qualified (-40 °C to +105 °C), ISO 26262 ASIL-B capable, and manufactured in NXP's IATF 16949-certified facilities. Its safety features - including System MPU, CRC, WDOG, EWM, and CSEc - are validated for automotive body electronics and powertrain auxiliary control.
How much on-chip memory does the FS32K118LIT0VLFR provide?
The FS32K118LIT0VLFR integrates 128 KB of ECC-protected program flash memory, 16 KB of ECC-protected SRAM, and 4 KB of FlexRAM that can be configured as either SRAM or EEPROM emulation. These memory resources are fully documented in the S32K1xx Data Sheet Rev. 15 "Memories and Memory Interfaces" chapter.
