Product details
Overview
FS32K116BRT0MLFR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for real-time control in body electronics, lighting, and power management systems. It operates from 2.7 V to 5.5 V, supports -40 °C to 125 °C ambient temperature (M-grade), delivers up to 48 MHz CPU frequency, integrates 128 KB flash with ECC, and features FlexCAN, LPUART, and 43 GPIOs.
For engineers reviewing the FS32K116BRT0MLFR datasheet, FS32K116BRT0MLFR pinout, FS32K116BRT0MLFR application, or FS32K116BRT0MLFR equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral configuration, and real-world use-case alignment for ASIL-B–capable automotive subsystems.
Technical Context
The FS32K116BRT0MLFR implements a single-core Arm Cortex-M0+ processor without FPU or DSP extensions, optimized for deterministic low-power operation in safety-critical automotive domains. It supports five power modes-HSRUN, RUN, STOP, VLPR, and VLPS-with HSRUN disabled (max 48 MHz) due to its M0+ core and M-grade thermal rating.
Its memory subsystem includes 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, 25 KB SRAM (including FlexRAM), and no Code Cache. Peripheral set excludes Ethernet, SAI, and second ADC module-confirmed by S32K11x feature comparison-and includes one FlexCAN (no CAN-FD), one 12-bit ADC (up to 32 channels), and one LPTMR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU or DSP - enables deterministic real-time execution with minimal interrupt latency for body control modules. |
| Max Clock Frequency | 48 MHz (L-grade speed bin) - matches S32K116's highest supported frequency; no HSRUN mode available on M0+ variants. |
| Flash Memory | 128 KB with ECC - provides robust code storage for automotive firmware requiring ISO 26262 ASIL-B compliance. |
| SRAM | 25 KB total (including 4 KB FlexRAM) - sufficient for RTOS stacks, CAN message buffers, and sensor data processing in lighting controllers. |
| Operating Temperature | -40 °C to +125 °C (M-grade) - qualified for under-hood and power distribution applications where junction temperature reaches 135 °C. |
| I/O Count | Up to 43 GPIOs - supports multiplexed LIN/CAN/ADC/SPI signals in compact 48-pin LQFP packages. |
| FlexCAN Channels | 1 module, standard CAN only - suitable for body domain networks without CAN-FD bandwidth requirements. |
| ADC | 1 × 12-bit SAR ADC, up to 32 inputs - enables simultaneous monitoring of battery voltage, temperature sensors, and PWM feedback in power switches. |
Pinout & Package
FS32K116BRT0MLFR is packaged in a 48-pin LQFP (LF package code), with 43 usable GPIOs, dedicated reset and clock pins, and power/ground distribution optimized for automotive PCB layouts with strict EMI and thermal constraints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled locally; VDDA and VDD shorted on PCB per AN5032 to maintain ADC accuracy across temperature. |
| RESET_b | Active-low reset input | Accepts external watchdog or power-on reset signal; internal pull-up ensures safe startup after brownout. |
| CLKIN / EXTAL | External crystal oscillator input | Supports 4–40 MHz crystals; used with SOSC for precise timing in LIN communication and RTC calibration. |
| SWD_DIO / SWD_CLK | Serial Wire Debug interface | Enables non-intrusive debug, flash programming, and runtime trace via NXP S32DS or IAR Embedded Workbench. |
| CAN0_TX / CAN0_RX | FlexCAN differential bus interface | Direct connection to ISO 11898-2 transceiver; no CAN-FD support - limits data rate to 1 Mbps in legacy body networks. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | Multiplexed across GPIOs; supports single-ended sampling at 1 Msps for thermistor, potentiometer, and current-sense monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU, ECC on flash/SRAM, CRC engine, and dual watchdog (WDOG + EWM) enable fault containment per ISO 26262 Part 6. |
| Low-Power Operation | VLPR/VLPS modes draw sub-10 µA; supports wake-up from LPTMR or GPIO edge for intermittent sensor polling in battery-powered modules. |
| Cryptographic Services Engine (CSEc) | Implements SHE-compliant AES-128, SHA-256, and key derivation - enables secure boot and firmware authentication without external security IC. |
| FlexIO Module | Configurable as UART, SPI, I2C, or PWM - replaces discrete logic in LED dimming, LIN slave emulation, and custom sensor interfaces. |
| Integrated LIN Transceiver Support | LPUART with automatic sync-break detection and checksum generation - reduces BOM count in door module and seat control units. |
Applications
| Body Control Module (BCM) | LED Headlamp Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118BRT0MLFR | 128 KB flash, 256 KB SRAM, same M0+ core and 48-pin LQFP package - adds second ADC module and 15 extra GPIOs. | Required when dual independent ADC sampling (e.g., simultaneous battery voltage + motor current) is needed in same footprint. | Select FS32K118BRT0MLFR if additional analog channel count or SRAM headroom justifies marginal cost increase. |
| S32K142WHT0VLF | M4F core, 80 MHz, 256 KB flash, 125 °C rating, but 64-pin LQFP - no pin compatibility; requires PCB redesign. | Needed for higher compute demand (e.g., sensor fusion, OTA update decryption) beyond M0+ capability. | Choose S32K142WHT0VLF only when migrating to M4F architecture for future scalability - not a drop-in replacement. |
Compared with FS32K116BRT0MLFR, FS32K118BRT0MLFR offers expanded analog I/O within identical packaging and thermal grade, while S32K142WHT0VLF delivers significantly higher performance at the cost of package incompatibility and increased power consumption - making FS32K116BRT0MLFR optimal for cost-sensitive, thermally constrained body electronics.

FAQ
What is the maximum operating frequency of the FS32K116BRT0MLFR?
The FS32K116BRT0MLFR operates at a maximum frequency of 48 MHz, as defined by its "L" speed grade in the ordering code. Unlike M4F-based S32K14x devices, it does not support HSRUN mode or frequencies above 48 MHz due to its Arm Cortex-M0+ core architecture and qualification envelope.
Does the FS32K116BRT0MLFR support CAN-FD?
No, the FS32K116BRT0MLFR includes only one FlexCAN module configured for classical CAN (ISO 11898-1) at up to 1 Mbps. CAN-FD support is absent in all S32K11x variants per the official S32K1xx feature comparison table and datasheet section 3.1.
What package type is used for the FS32K116BRT0MLFR?
The FS32K116BRT0MLFR uses a 48-pin LQFP package (package code "LF"), with exposed pad for thermal dissipation. This is confirmed by the ordering code suffix "LF" and the S32K11x package matrix in Figure 3 of the datasheet.
Is the FS32K116BRT0MLFR qualified for automotive safety standards?
Yes, the FS32K116BRT0MLFR is ISO 26262 ASIL-B capable, featuring ECC on flash and SRAM, System MPU, dual watchdogs (WDOG and EWM), CRC engine, and lockstep-capable peripherals - all documented in the S32K1xx Safety Manual and certified by TÜV SÜD.
Can the FS32K116BRT0MLFR execute CSEc cryptographic operations in RUN mode?
Yes, the FS32K116BRT0MLFR supports CSEc (Cryptographic Services Engine) operations in RUN mode at 48 MHz. Unlike HSRUN-capable M4F devices, it has no HSRUN mode - so CSEc execution is fully enabled without mode switching, per Section 1.1 and footnote 1 in the datasheet.
