Product details
Overview
FS32K116LFT0MLFT 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, and features CSEc cryptographic engine for secure boot and key management in ECU applications.
For engineers reviewing the FS32K116LFT0MLFT datasheet, FS32K116LFT0MLFT pinout, FS32K116LFT0MLFT application, or FS32K116LFT0MLFT equivalent, this page delivers verified technical context, package mapping, functional alternatives, and supply-chain-ready availability details - all aligned to the S32K1xx Rev. 15 data sheet and orderable part number list.
Technical Context
The FS32K116LFT0MLFT implements an Arm Cortex-M0+ core with Thumb®-2 ISA, supporting up to 48 MHz operation (via FIRC or SOSC), and includes a configurable NVIC, CRC module, and system MPU for ASIL-B–capable memory protection. Its clock architecture integrates FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL for flexible low-power timing.
Power management includes five modes (HSRUN, RUN, STOP, VLPR, VLPS), though HSRUN is disabled on K116 - only RUN mode (48 MHz) is supported. Memory subsystem comprises 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, 25 KB SRAM (including FlexRAM), and 2 KB code cache to reduce latency impact.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, Thumb-2 ISA, no FPU - optimized for deterministic real-time control with minimal interrupt latency. |
| Clock Speed | 48 MHz max (FIRC or SOSC) - fixed frequency; HSRUN mode not available on K116 series per feature comparison table. |
| Flash / ECC | 128 KB program flash with Error-Correcting Code - enables single-bit error correction and double-bit error detection for ASIL-B compliance. |
| SRAM | 25 KB total (23 KB main + 2 KB FlexRAM) - FlexRAM configurable as SRAM or EEPROM emulation, critical for wear-leveling in nonvolatile data storage. |
| Temperature Grade | -40 °C to +125 °C (M-grade) - qualified for under-hood automotive applications requiring extended thermal robustness. |
| Security | Cryptographic Services Engine (CSEc) - supports AES-128/256, SHA-256, RNG, and secure boot; requires RUN mode (not HSRUN) for execution. |
| I/O Count | Up to 43 GPIO pins - confirmed for 48-pin LQFP package; includes NMI, wakeup capability, and configurable pull-up/down resistors. |
Pinout & Package
FS32K116LFT0MLFT is packaged in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, with exposed thermal pad. Pin functions are defined in the S32K1xx Reference Manual IO Signal Description sheets and validated against the S32K11x family block diagram and feature comparison matrix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power and analog reference | Single 2.7–5.5 V supply; VDD and VDDA must be shorted on PCB; VREFH ≤ VDDA + 0.1 V ensures ADC accuracy within spec. |

| SWD_CLK / SWD_IO | Serial Wire Debug interface | Two-pin debug port supporting full SWD protocol - enables programming, real-time trace, and secure debug authentication via CSEc. |
| PTA0–PTA31, PTB0–PTB10 | GPIO multiplexed I/O | 43 total GPIOs across PORTA/B; each supports interrupt-on-change, edge-triggered wake-up, and configurable drive strength. |
| LPUART0_RX / TX | Low-power UART channel | Dedicated LIN-capable UART (v1.3–2.2A, SAE J2602) - operates in VLPR/VLPS modes for battery-sensitive body control modules. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready System MPU | NXP's crossbar-level MPU enforces access rights per master (core/DMA), preventing unauthorized memory access - essential for ISO 26262 software partitioning. |
| FlexNVM EEPROM Emulation | 2 KB FlexNVM + 2 KB FlexRAM enable true EEPROM behavior with wear leveling and atomic write/erase - eliminates need for external serial EEPROM. |
| Low-Power Communication Suite | 1× LPUART, 1× LPSPI, 1× LPI2C - all support DMA and deep-sleep wake-up, reducing CPU load and extending battery life in always-on modules. |
| Integrated Safety Peripherals | CRC module, WDOG, EWM, and ECC on flash/SRAM - provides hardware-level fault detection and recovery for functional safety monitoring paths. |
| Automotive-Grade Clock System | FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) - enables fail-safe clock switching and precise RTC timekeeping across temperature ranges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LFT0MLFT | Same package and pinout; adds 256 KB flash, 4 KB FlexRAM, and second 12-bit ADC module - no change to core or clock architecture. | Supports higher-complexity body domain controllers requiring dual ADC sampling or larger firmware image size. | Select when >128 KB flash or redundant analog sensing is required; maintains identical layout and qualification path. |
| S32K142WFT0VLFT | Arm Cortex-M4F core, 80 MHz, 256 KB flash, 125 °C rating, but uses 48-pin LQFP with different pin mapping - not pin-compatible. | Targeted at higher-performance applications like gateway modules or advanced driver assistance sub-systems needing DSP/FPU. | Choose only if M4F performance, FPU, or additional peripherals (e.g., FlexCAN FD) justify PCB redesign and requalification. |
Compared with FS32K116LFT0MLFT, FS32K118LFT0MLFT offers scalable flash/RAM within identical footprint and qualification, while S32K142WFT0VLFT delivers higher compute but requires layout revision and introduces M4F-specific toolchain dependencies.

FAQ
What is the maximum operating frequency of the FS32K116LFT0MLFT?
The FS32K116LFT0MLFT operates at a maximum frequency of 48 MHz using the Fast Internal RC oscillator (FIRC) or external crystal (SOSC). Unlike higher-tier S32K14x devices, the K116 variant does not support HSRUN mode or 112 MHz operation - its top speed is fixed at 48 MHz in RUN mode, as confirmed in the S32K1xx feature comparison table and ordering guide.
Does the FS32K116LFT0MLFT support CAN-FD communication?
No, the FS32K116LFT0MLFT does not support CAN-FD. According to the S32K1xx feature comparison chart, only S32K142 and above include FlexCAN modules with CAN-FD capability. The K116 integrates a single FlexCAN module compliant with classical CAN 2.0B only - sufficient for LIN-coordinated body networks but not high-speed powertrain or ADAS backbones.
What package type and pin count does the FS32K116LFT0MLFT use?
The FS32K116LFT0MLFT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This matches the "LF" package code in the ordering nomenclature and is explicitly listed in the S32K1xx feature comparison table as the standard option for K116 devices - supporting up to 43 GPIOs and full peripheral routing within automotive PCB constraints.
Is the FS32K116LFT0MLFT qualified for automotive AEC-Q100 Grade 1?
Yes, the FS32K116LFT0MLFT is AEC-Q100 qualified for Grade 1 (-40 °C to +125 °C ambient), as indicated by its "M" temperature grade suffix and confirmed in the S32K1xx data sheet's thermal operating characteristics table. This qualification covers transient immunity, ESD robustness, and lifetime reliability testing required for under-hood and interior automotive applications.
Can the FS32K116LFT0MLFT execute CSEc security functions in RUN mode?
Yes, the FS32K116LFT0MLFT can execute CSEc cryptographic operations - including AES encryption, SHA hashing, and secure boot verification - in RUN mode. As stated in the data sheet, CSEc and EEPROM writes/erases are prohibited in HSRUN mode, but since HSRUN is not implemented on K116, all CSEc activity occurs safely at 48 MHz in RUN mode without requiring mode switching or performance penalty.
