Product details
Overview
FS32K116BRT0MFMT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for functional safety-critical body electronics and powertrain control applications. 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, 1x FlexCAN, 1x LPUART/LIN, and 43 GPIOs.
For engineers reviewing the FS32K116BRT0MFMT datasheet, FS32K116BRT0MFMT pinout, FS32K116BRT0MFMT application, or FS32K116BRT0MFMT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases in automotive subsystems, and validated alternative parts - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K116BRT0MFMT implements an Arm Cortex-M0+ core optimized for deterministic real-time control in ASIL-B capable systems. It supports dual power modes: RUN (up to 48 MHz) and VLPR (low-power run), with PMC-managed transitions between HSRUN, RUN, STOP, VLPR, and VLPS states - though HSRUN mode is not available on this variant.
Its peripheral set includes one 12-bit ADC (1 Msps, up to 13 channels), one Analog Comparator with integrated 8-bit DAC, one Low Power Timer (LPTMR), one LPIT with 4 channels, one RTC, one PDB, and one TRGMUX - all synchronized via a unified clock gating architecture tied to FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz) sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, 48 MHz max - enables deterministic real-time execution with low interrupt latency for body control modules. |
| Flash / ECC | 128 KB program flash with Error-Correcting Code - ensures data integrity and meets ISO 26262 ASIL-B requirements for safety-critical code storage. |
| SRAM / FlexRAM | 25 KB total SRAM (including 4 KB FlexRAM configurable as RAM or EEPROM emulation) - supports robust runtime data handling and non-volatile parameter storage without external EEPROM. |
| Operating Temp | -40 °C to +125 °C (M-grade) - qualified for under-hood automotive environments including engine control units and junction boxes. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with wide-range 12 V vehicle battery systems, including cold-crank and load-dump conditions. |
| FlexCAN | 1x CAN 2.0B controller (no CAN-FD) - provides robust communication for LIN/CAN gateway functions and sensor actuator networks. |

Pinout & Package
FS32K116BRT0MFMT is packaged in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments are defined per the S32K11x IO Signal Description multiplexing sheet and align with the 48-pin LQFP footprint shared across K116/K118 variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and stable core operation. |
| RESET_b | Active-low reset input | Accepts external reset assertion; internal POR and LVD provide fail-safe startup and brownout recovery. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and real-time trace via NXP S32DS or third-party tools (IAR/GHS). |
| CAN0_TX / CAN0_RX | FlexCAN channel 0 differential pair | Direct connection to external CAN transceiver (e.g., TJA1042); supports bit rates up to 1 Mbps in automotive networks. |
| ADC0_SE0–ADC0_SE12 | Analog input channels | 13 single-ended inputs mapped to pins; supports ratiometric sensing with internal 1.2 V reference or external VREFH. |
| PTE0–PTE31, PTB0–PTB11 | GPIO bank terminals | Configurable pull-up/down, slew rate, and drive strength; supports edge-triggered interrupts for wake-from-stop functionality. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | System MPU enforces memory access rights across core, DMA, and peripherals - preventing unauthorized access to safety-critical regions. |
| Functional Safety Support | Built-in CRC module, WDOG, EWM, and lock-step ready peripherals enable compliance with ISO 26262 Part 6 requirements for diagnostic coverage. |
| Low-Power Operation | VLPR mode draws < 100 µA at 4 MHz; STOP mode consumes ~2 µA - extends battery life in always-on vehicle modules like door modules. |
| Secure Boot & Firmware Updates | CSEc performs SHA-256 hash verification and AES-128 decryption of signed firmware images - enabling trusted OTA update pipelines. |
| Robust Analog Subsystem | 12-bit ADC with hardware averaging, offset calibration, and window compare - reduces software overhead for battery voltage monitoring and thermistor reading. |
| Flexible Clock Management | FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) sources with dynamic switching - ensures timing resilience during voltage transients. |

FAQ
What is the maximum operating frequency of the FS32K116BRT0MFMT?
The FS32K116BRT0MFMT operates at a maximum frequency of 48 MHz in RUN mode, driven by the 48 MHz Fast Internal RC oscillator (FIRC). Unlike higher-tier S32K14x devices, it does not support HSRUN mode or 112 MHz operation - its clock tree is optimized for deterministic low-latency control in cost-sensitive automotive modules.
Does FS32K116BRT0MFMT support CAN-FD?
No, FS32K116BRT0MFMT includes one FlexCAN module compliant with ISO 11898-1 (Classical CAN 2.0B) only, with bit rates up to 1 Mbps. CAN-FD support is reserved for S32K14x series devices (e.g., K142/K144) and requires specific ordering option 'F' or 'A1' - not present in the FS32K116BRT0MFMT part number encoding.
What package type and pin count does FS32K116BRT0MFMT use?
FS32K116BRT0MFMT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This matches the pinout of other S32K11x 48-pin variants (e.g., FS32K118BRT0MFMT), enabling drop-in replacement where memory and peripheral requirements align.
Is FS32K116BRT0MFMT qualified for automotive AEC-Q100 Grade 1?
Yes, FS32K116BRT0MFMT is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C ambient), as confirmed by its 'M' temperature suffix and inclusion in the S32K1xx datasheet Rev. 15. Its junction temperature limit is 135 °C in RUN mode, meeting full Grade 1 thermal specifications for under-hood deployment.
Can FS32K116BRT0MFMT execute CSEc cryptographic operations in RUN mode?
Yes, FS32K116BRT0MFMT can execute CSEc (Cryptographic Services Engine) operations - including AES-128 encryption, SHA-256 hashing, and secure key storage - in RUN mode at 48 MHz. The datasheet explicitly prohibits CSEc use only in HSRUN mode (not supported on this variant), confirming full security functionality at its rated operating frequency.
