Product details
Overview
FS32K116BRT0VFMR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for real-time control in body electronics, lighting, and gateway modules. 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, 25 KB SRAM, and CSEc cryptographic security engine.
For engineers reviewing the FS32K116BRT0VFMR datasheet, FS32K116BRT0VFMR pinout, FS32K116BRT0VFMR application, or FS32K116BRT0VFMR equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing/power/security constraints - all confirmed against NXP's S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K116BRT0VFMR implements a single-core Arm Cortex-M0+ processor with Thumb®-2 ISA, 1.25 DMIPS/MHz performance, and integrated NVIC, FPU, and debug infrastructure (SWD/JTAG, ITM, DWT). Its memory subsystem includes ECC-protected 128 KB program flash, 25 KB SRAM (including FlexRAM), and 4 KB FlexRAM configurable as EEPROM emulation.
Power management features five modes (HSRUN/RUN/STOP/VLPR/VLPS), with HSRUN disabled for CSEc operations - requiring mode switch to RUN (48 MHz) for security or EEPROM writes. Peripheral set includes one 12-bit ADC (up to 32 channels), one LPUART/LIN, one LPSPI, one LPI2C, one FlexCAN (CAN-FD capable), one FTM timer, and CSEc supporting SHE-compliant cryptographic functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, Thumb-2 ISA, 1.25 DMIPS/MHz - enables deterministic real-time control with low power footprint |

Pinout & Package
FS32K116BRT0VFMR is packaged in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), pin-compatible with other S32K11x devices in the same package variant per NXP's pin-to-pin compatibility statement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital power supply inputs | Must be decoupled locally; VDD and VDDA shorted on PCB per AN5032 - ensures ADC/CMP accuracy and noise immunity |
| RESET_B | Active-low reset input | Asynchronous, level-sensitive reset - requires external pull-up and debouncing for robust ECU startup |
| SWD_CLK / SWD_DIO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and runtime trace without JTAG pins |
| PTA0–PTA31, PTB0–PTB15 | GPIO with interrupt capability | Up to 43 GPIOs available in 48-pin LQFP - supports wake-up, PWM output, and LIN bus physical layer signaling |
| LPUART0_RX / LPUART0_TX | Low-power UART channel | Supports LIN 2.2A protocol at 19.2 kbps - used for diagnostic communication in sleep/wake scenarios |
| FLEXCAN0_TX / FLEXCAN0_RX | CAN-FD transceiver interface | Enables ISO 11898-1 CAN FD messaging up to 5 Mbps - requires external transceiver for physical layer |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | Includes ECC on flash/SRAM, System MPU, CRC module, WDOG/EWM, and lockstep-capable peripherals - meets ISO 26262 requirements for body control applications |

Applications
| Body Control Module (BCM) | Automotive Lighting Controller |
|---|---|
Use Scenario: Centralized management of door locks, window lifts, mirrors, and interior lighting in modern passenger vehicles. IC Role / Device Role / Timing Role: Main MCU executing real-time control logic, LIN slave communication, and fault diagnostics with sub-100 µs interrupt latency. Use Value: 48 MHz Cortex-M0+ core and 43 GPIOs support concurrent LIN, CAN, and PWM outputs - enabling consolidation of multiple legacy discrete controllers into one BOM line. |
Use Scenario: Adaptive front-lighting system (AFS) and dynamic rear combination lamps with PWM dimming and thermal derating. IC Role / Device Role / Timing Role: Timing-critical PWM generator with FTM and ADC feedback loop for LED current regulation and junction temperature monitoring. Use Value: Integrated 12-bit ADC and FTM enable closed-loop brightness control without external op-amps or DACs - reducing bill-of-materials and board area. |

Use Scenario: Protocol translation between LIN-sensor networks (e.g., seat position, HVAC actuators) and CAN backbone in vehicle domain architecture. IC Role / Device Role / Timing Role: Dual-interface bridge MCU handling LIN master/slave and CAN FD message routing with timestamp synchronization. Use Value: Single FS32K116BRT0VFMR replaces dual-chip solutions - LPUART + FlexCAN + CSEc allow secure, low-latency bridging with firmware update authentication. |
Use Scenario: Power distribution and load switching for 12 V accessories (e.g., fans, pumps, solenoids) with overcurrent protection and energy metering. IC Role / Device Role / Timing Role: High-reliability power manager using GPIO-driven high-side switches, ADC-based current sensing, and watchdog-monitored state machine. Use Value: ECC flash and System MPU prevent corruption during voltage transients - critical for fail-safe load disconnection in ASIL-B compliant junction boxes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118BRT0VFMR | Same package, 256 KB flash, 64 KB SRAM, identical peripherals - adds 128 KB more program memory | Preferred for designs requiring larger bootloader, OTA update partition, or expanded diagnostics firmware | Select when future firmware growth or dual-bank OTA is required; pin-compatible drop-in upgrade path |
| S32K142WFT0MLHR | M-grade (-40 °C to 150 °C), Cortex-M4F core (80 MHz), 256 KB flash, Ethernet + SAI - not pin-compatible | Targeted at under-hood powertrain or ADAS edge nodes needing higher compute, extended temp, or audio networking | Choose only if M-grade temp, Ethernet MAC, or floating-point DSP acceleration is mandatory - requires PCB redesign |
Compared with FS32K116BRT0VFMR, FS32K118BRT0VFMR offers scalable memory within identical footprint and toolchain, while S32K142WFT0MLHR delivers higher performance and extended temperature range at the cost of package incompatibility and increased BOM complexity.

FAQ
What is the maximum operating frequency of the FS32K116BRT0VFMR?
The FS32K116BRT0VFMR operates at up to 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is reserved for higher-memory S32K14x variants. This 48 MHz frequency is fully validated for all peripherals, CSEc execution, and EEPROM emulation - ensuring deterministic timing in automotive control loops.
Does the FS32K116BRT0VFMR support CAN-FD?
Yes, the FS32K116BRT0VFMR includes one FlexCAN module with CAN-FD capability per the S32K1xx datasheet Feature Comparison table. It supports ISO 11898-1 CAN FD up to 5 Mbps, but requires an external CAN transceiver for physical layer interfacing - no integrated transceiver is present on-die.
What package type and pin count does FS32K116BRT0VFMR use?
FS32K116BRT0VFMR uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as confirmed by NXP's ordering information diagram and S32K1xx product series comparison. This package is pin-to-pin compatible with other S32K11x devices in the same LQFP-48 variant, enabling hardware reuse across memory/configurations.
Is CSEc (Cryptographic Services Engine) available on FS32K116BRT0VFMR?
Yes, FS32K116BRT0VFMR integrates the full CSEc engine supporting SHE v1.1 cryptographic functions (AES-128, SHA-256, RNG, key vaulting). CSEc operations require RUN mode (48 MHz); they are explicitly prohibited in HSRUN mode - a constraint documented in the S32K1xx datasheet for all K11x devices.
What is the flash memory size and ECC support for FS32K116BRT0VFMR?
FS32K116BRT0VFMR contains 128 KB of program flash memory with full Error-Correcting Code (ECC) protection, as specified in the S32K1xx datasheet Features section and Memory chapter. ECC detects and corrects single-bit errors and detects double-bit errors - essential for ASIL-B compliance in automotive software execution.
Can FS32K116BRT0VFMR operate from a 3.3 V supply?
Yes, FS32K116BRT0VFMR supports 2.7 V to 5.5 V operation, making it fully compatible with standard 3.3 V automotive supply rails. Its VDD min specification (2.7 V) is validated across all operating modes and temperatures - unlike S32K14xW variants, which require minimum 3.13 V.
