Product details
Overview
FS32K116LFT0MFMT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. 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, and integrates 128 KB flash with ECC, 25 KB SRAM, and CSEc cryptographic engine.
For engineers reviewing the FS32K116LFT0MFMT datasheet, FS32K116LFT0MFMT pinout, FS32K116LFT0MFMT application, or FS32K116LFT0MFMT equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral configuration, and real-world selection guidance for ASIL-B–capable automotive MCU integration.
Technical Context
The FS32K116LFT0MFMT implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode. It uses NXP's system-level MPU (not Arm Core MPU) for memory protection across crossbar masters including core and DMA, supporting ISO 26262 ASIL-B compliance.
Its clock architecture includes FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz), with SPLL disabled - confirming absence of HSRUN mode and 112 MHz operation. Power modes are limited to RUN, STOP, VLPR, and VLPS; CSEc and EEPROM operations are permitted only in RUN mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, fixed 48 MHz max - eliminates floating-point overhead and simplifies timing-critical deterministic execution. |
| Flash Memory | 128 KB program flash with ECC - ensures bit-error resilience in automotive ECU firmware storage. |
| SRAM | 25 KB on-chip SRAM with ECC - protects runtime variables and stack integrity against soft errors. |
| Operating Voltage | 2.7 V to 5.5 V - compatible with 12 V automotive battery systems including cold-crank (down to 2.7 V). |
| Ambient Temperature | -40 °C to +125 °C (M-grade) - qualified for under-hood and transmission-control applications. |
| Cryptographic Engine | CSEc (Secure Hardware Extension) - enables AES-128, SHA-256, and key management per SHE specification, required for secure boot and OTA updates. |
| I/O Count | Up to 43 GPIO pins - sufficient for LIN gateway, sensor fusion, and actuator interface in compact ECUs. |
| ADC | One 12-bit SAR ADC with up to 32-channel input multiplexing - supports analog sensor monitoring (e.g., temperature, pressure) at 1 Msps sampling rate. |
Pinout & Package
FS32K116LFT0MFMT is packaged in a 48-pin LQFP (LF package code), 7 mm × 7 mm, 0.5 mm pitch, thermally enhanced with exposed pad. Pinout conforms to S32K11x family layout per NXP reference manual Rev. 15.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled individually; VDDA/VREFH require low-noise filtering for ADC accuracy - critical for sensor signal chain integrity. |
| RESET_b | Active-low reset input | Asynchronous, level-sensitive reset with internal pull-up; requires external RC filter for ESD/EMI immunity in automotive environments. |
| SWD_DIO / SWD_CLK | Serial Wire Debug interface | Two-pin debug port supporting full JTAG/SWD functionality - enables in-circuit programming and real-time trace without dedicated JTAG pins. |
| LPUART0_RX / LPUART0_TX | Low-power UART channel 0 | Dedicated LIN-capable UART with automatic baud-rate detection - used for diagnostic communication (UDS over LIN) in sleep/wake scenarios. |
| FLEXCAN0_TX / FLEXCAN0_RX | CAN 2.0B transceiver interface | Direct connection to external CAN transceiver (e.g., TJA1042); supports wake-on-CAN in STOP mode - essential for networked ECU coordination. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready System MPU | NXP's crossbar-level MPU enforces memory access rights for core, DMA, and peripherals - satisfies partitioning requirements for mixed-criticality software (e.g., body control + diagnostics). |
| Low-Power Timer Suite | LPTMR + LPIT + RTC enable precise wake-from-sleep timing at sub-millisecond resolution - reduces quiescent current in always-on modules like door controllers. |
| FlexIO Peripheral | Configurable logic block supporting UART/I²C/SPI emulation - replaces discrete protocol translators and reduces BOM count in legacy interface bridging. |
| CRC Accelerator | Hardware CRC-32 generator with DMA chaining - accelerates firmware image validation and flash checksum calculation during boot and OTA update verification. |
| EEPROM Emulation | 4 KB FlexRAM configured as EEPROM-equivalent nonvolatile storage - eliminates external EEPROM chip while retaining wear-leveling and atomic write semantics. |
Applications
| Body Control Module (BCM) | Door Module Controller |

IC Role / Device Role / Timing Role: Analog front-end processor converting raw capacitance measurements into calibrated occupancy states using ADC + CMP + DAC. Use Value: Integrated 8-bit DAC for reference voltage generation and comparator hysteresis control eliminates 2 external components per sensor channel. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LFT0MFMT | 256 KB flash, 32 KB SRAM, same 48-pin LQFP package and M-grade temp range - identical pinout and peripheral set. | Supports larger AUTOSAR OS images and more complex diagnostic stacks; suitable when future firmware expansion is anticipated. | Select FS32K118LFT0MFMT if >128 KB flash is required for bootloader + application + secure update partitioning. |
| S32K116MLT0MFMT | Same core, memory, and peripherals but with LQFP-64 package (64 pins) - adds 15 extra GPIOs and second LPUART/LPSPI channel. | Enables dual-LIN gateway or expanded sensor interface without redesign; not drop-in due to package change. | Choose S32K116MLT0MFMT only when additional I/O or communication channels justify PCB re-layout and cost increase. |
Compared with FS32K116LFT0MFMT, FS32K118LFT0MFMT offers scalable flash headroom within identical footprint and thermal envelope, while S32K116MLT0MFMT trades pin compatibility for I/O expansion - making the former ideal for lifecycle extension and the latter for functional growth requiring hardware revision.

FAQ
What is the maximum operating frequency of the FS32K116LFT0MFMT?
The FS32K116LFT0MFMT operates at a maximum frequency of 48 MHz in RUN mode. It does not support HSRUN mode or 112 MHz operation - this is confirmed by its ordering code 'L' (48 MHz with DMA) and exclusion from S32K14x series features. All timing-critical peripherals (FTM, LPUART, CAN) are fully functional at this speed.
Does the FS32K116LFT0MFMT support CAN FD?
No, the FS32K116LFT0MFMT does not support CAN FD. Its FlexCAN module implements CAN 2.0B only, as indicated by the absence of 'F' or 'A1' in the Y-field of its part number (FS32K116LFT0MFMT). CAN FD capability is reserved for S32K14x devices with 'F' or higher feature codes.
What package type is used for the FS32K116LFT0MFMT?
The FS32K116LFT0MFMT uses a 48-pin LQFP package (package code 'LF'), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This matches the S32K11x family's standard 48-pin LQFP footprint and is pin-compatible with other S32K11x variants in the same package.
Is the FS32K116LFT0MFMT qualified for automotive AEC-Q100 Grade 1?
Yes, the FS32K116LFT0MFMT is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C ambient), as confirmed by its 'M' temperature grade suffix and inclusion in the S32K11x automotive MCU family. This qualification covers all electrical, thermal, and reliability tests required for under-hood and transmission-control applications.
Can the FS32K116LFT0MFMT execute CSEc security functions in HSRUN mode?
No, the FS32K116LFT0MFMT cannot execute CSEc security functions in HSRUN mode because it does not support HSRUN mode at all. CSEc operations (e.g., AES encryption, key derivation) are permitted only in RUN mode at 48 MHz - consistent with its 'L' speed grade and documented operational constraints in the S32K1xx datasheet Rev. 15.
