Product details
Overview
FS32K116LIT0VFMR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for real-time control in safety-critical ECUs. 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 body control modules and LIN-based sensor nodes.
For engineers reviewing the FS32K116LIT0VFMR datasheet, FS32K116LIT0VFMR pinout, FS32K116LIT0VFMR application, or FS32K116LIT0VFMR equivalent, key selection criteria include its V-grade thermal rating, 48-pin LQFP package, LIN-capable LPUART peripherals, FlexTimer-based PWM generation, and mandatory RUN-mode execution for CSEc/EEPROM operations - all critical for ASIL-B compliant automotive subsystems.
Technical Context
The FS32K116LIT0VFMR implements an Arm Cortex-M0+ core without FPU, operating at up to 48 MHz in RUN mode with 1.25 DMIPS/MHz performance. Its memory subsystem includes 128 KB program flash (ECC-protected), 16 KB SRAM (ECC-protected), and 2 KB FlexRAM usable as SRAM or EEPROM emulation.
Power management uses PMC-controlled HSRUN/RUN/STOP/VLPR/VLPS modes; however, FS32K116LIT0VFMR disables HSRUN mode entirely - confirmed by S32K11x feature comparison showing "up to 48 MHz" max frequency and absence of 112 MHz capability. All security (CSEc) and EEPROM write/erase operations require explicit transition to RUN mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, 48 MHz max - optimized for deterministic real-time control with low interrupt latency. |
| Flash Memory | 128 KB with ECC - enables robust code storage and ASIL-B compliance per ISO 26262 functional safety requirements. |
| SRAM | 16 KB with ECC - provides fault-tolerant data workspace for safety-critical variables and stack operations. |
| Operating Voltage | 2.7 V to 5.5 V - supports direct connection to automotive battery rails with transient tolerance up to 5.8 V (60 s lifetime). |
| Ambient Temperature | -40 °C to +105 °C (V-grade) - qualified for under-hood and cabin ECU deployment without derating. |
| Peripherals | 1× LPUART/LIN, 1× LPSPI, 1× LPI2C, 1× FlexCAN (CAN-FD capable), 2× FlexTimer (16-bit, 16 channels total), 1× 12-bit ADC (32-channel mux) |
| Security | Cryptographic Services Engine (CSEc) - implements SHE-compliant AES-128, SHA-256, RNG, and secure boot; requires RUN mode execution. |
Pinout & Package
FS32K116LIT0VFMR is housed in a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant and moisture-sensitive level 3. Pin functions are defined per S32K11x IO Signal Description multiplexing tables; all I/O pins support interrupt capability and configurable pull-up/down.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply inputs | Must be shorted on PCB with local decoupling; VDDA/VREFH define ADC accuracy and analog reference stability. |
| RESET_b | Active-low reset input | Asynchronous reset signal; internal pull-up ensures safe startup; external watchdog or EWM can assert this line. |
| SWD_CLK / SWD_DIO | Debug interface signals | Serial Wire Debug port - enables full JTAG/SWD debugging, flash programming, and trace via NXP S32DS or third-party tools. |
| LPUART0_TX / LPUART0_RX | LIN/UART communication I/O | Dedicated pins for LIN 2.2A-compliant transceiver interface; supports automatic baud rate detection and sleep/wake framing. |
| FTM0_CH0–CH7 | FlexTimer output channels | Configurable PWM, input capture, or quadrature decode outputs - used for motor control, LED dimming, or encoder interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU enforces memory region access rights across core and DMA; ECC on flash/SRAM enables error detection/correction per ISO 26262. |
| Low-Power Operation | VLPR/VLPS stop modes achieve sub-μA current draw; LPTMR and LPIT enable precise wake-up timing without CPU intervention. |
| LIN Protocol Support | LPUART module natively implements LIN 1.3/2.0/2.1/2.2A and SAE J2602 - eliminates need for external protocol stack or transceiver logic. |
| Functional Safety Resources | Integrated CRC module, WDOG, EWM, and lockstep-ready crossbar switch - supports diagnostic coverage for ASIL-B system integration. |
| Secure Boot & Key Management | CSEc engine performs authenticated boot, key wrapping, and secure firmware updates - keys stored in protected non-volatile memory. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LIT0VFMR | Same package and core, but with 256 KB flash, 32 KB SRAM, and dual 12-bit ADC modules - no change in clock speed or temperature grade. | Supports larger firmware images and additional sensor channels; suitable when extended memory or redundant ADC paths are required. | Select FS32K118LIT0VFMR only if application demands >128 KB flash or dual ADC acquisition - otherwise FS32K116LIT0VFMR offers optimal BOM cost. |
| S32K142WLLT0VPBR | Arm Cortex-M4F core, 80 MHz, 256 KB flash, M-grade (-40 °C to +150 °C), 64-pin LQFP - higher performance and extended temperature range. | Targeted at under-hood powertrain or transmission control where 150 °C ambient and floating-point math are essential. | Choose S32K142WLLT0VPBR only for M-grade thermal environments or when DSP/FPU acceleration is needed - not a drop-in replacement due to pin count and voltage range differences. |
Compared with FS32K116LIT0VFMR, FS32K118LIT0VFMR extends memory capacity without altering footprint or thermal specs, while S32K142WLLT0VPBR shifts to M-grade operation and M4F architecture - making both alternatives application-specific upgrades rather than direct substitutes.

FAQ
What is the maximum operating frequency of the FS32K116LIT0VFMR?
The FS32K116LIT0VFMR operates at a maximum frequency of 48 MHz in RUN mode. Unlike higher-tier S32K14x devices, it does not support HSRUN mode or 112 MHz operation - confirmed by S32K11x feature comparison tables and ordering code decoding ('V' = 48 MHz with DMA). This frequency is fully supported across its -40 °C to +105 °C operating range.
Does the FS32K116LIT0VFMR support CAN-FD communication?
Yes, the FS32K116LIT0VFMR includes one FlexCAN module that supports CAN-FD per ISO 11898-1, as verified in the S32K1xx feature comparison table. However, CAN-FD operation requires external CAN-FD transceiver hardware and proper configuration of bit timing registers - the MCU itself provides full protocol stack support via SDK drivers.
What package type and pin count does the FS32K116LIT0VFMR use?
The FS32K116LIT0VFMR uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), as indicated by the 'LF' suffix in its ordering code and confirmed in the S32K1xx packaging options table. This package is pin-compatible with other 48-pin S32K11x variants, enabling shared PCB layouts across memory-graded derivatives.
Can CSEc security functions be executed in HSRUN mode on the FS32K116LIT0VFMR?
No - the FS32K116LIT0VFMR does not support HSRUN mode at all, so this restriction does not apply. All CSEc operations (secure boot, key generation, AES encryption) execute in RUN mode at 48 MHz, consistent with its fixed-frequency architecture and documented requirement to avoid simultaneous high-speed execution and security writes.
Is the FS32K116LIT0VFMR qualified for automotive applications under AEC-Q100?
Yes, the FS32K116LIT0VFMR is AEC-Q100 Grade 2 qualified (operating from -40 °C to +105 °C), as confirmed by its 'V' temperature grade designation and inclusion in NXP's official S32K1xx automotive MCU portfolio. It also supports ISO 26262 ASIL-B development workflows through integrated safety mechanisms like ECC, MPU, and WDOG.
