Product details
Overview
FS32K116LAT0MFMT 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 security engine, FlexCAN (1 channel), and LPUART/LIN interfaces. It targets ECU applications requiring ASIL-B compliance and functional safety support.
For engineers reviewing the FS32K116LAT0MFMT datasheet, FS32K116LAT0MFMT pinout, FS32K116LAT0MFMT application, or FS32K116LAT0MFMT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases in automotive subsystems, and two validated alternative parts - all grounded in NXP's official S32K1xx Data Sheet Rev. 15 (March 2026).
Technical Context
The FS32K116LAT0MFMT implements an Arm Cortex-M0+ core optimized for deterministic low-power operation in automotive environments. It supports five power modes (HSRUN, RUN, STOP, VLPR, VLPS), with HSRUN disabled - its maximum operational frequency is 48 MHz in RUN mode, consistent with the "L" speed grade and M-temperature rating (-40 °C to 125 °C).
It integrates a single 12-bit ADC (up to 32 channels), one FlexTimer (8-channel), one LPTMR, one LPIT (4-channel), and one PDB. Peripherals include one FlexCAN module (CAN-FD capable), three LPUART/LIN modules, two LPSPI, one LPI2C, and FlexIO for protocol emulation - all with DMA support via 16-channel eDMA and DMAMUX.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, 48 MHz max - enables deterministic real-time control with low interrupt latency and energy efficiency for battery-sensitive ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LAT0MFMT | Same package and pinout; upgrades to 256 KB flash, 32 KB SRAM, and adds second 12-bit ADC module. | Required when higher memory headroom or dual ADC acquisition (e.g., simultaneous coolant/oil temp monitoring) is needed. | Select FS32K118LAT0MFMT if future firmware expansion or redundant sensor processing is anticipated - no PCB change required. |
| S32K116LHT0VFMR | Same core and peripheral set but rated for -40 °C to 105 °C (V-grade) and supplied in 32-pin QFN (FM package). | Suitable for cabin modules (e.g., HVAC controls) where ambient temperature stress is lower and board space is constrained. | Choose S32K116LHT0VFMR only for cost-sensitive, space-limited interior applications - requires PCB redesign due to QFN footprint and reduced I/O count. |
Compared with FS32K116LAT0MFMT, FS32K118LAT0MFMT offers scalable memory without layout changes, while S32K116LHT0VFMR trades temperature robustness and I/O count for compact packaging - making the former ideal for forward-compatible designs and the latter for space-constrained cabin ECUs.

FAQ
What is the maximum operating frequency of the FS32K116LAT0MFMT?
The FS32K116LAT0MFMT operates at a maximum frequency of 48 MHz in RUN mode. Its speed grade "L" explicitly denotes 48 MHz capability, and it does not support HSRUN mode (112 MHz), which is reserved for M4F-core variants like the S32K14x series. This frequency is fully supported across its -40 °C to 125 °C operating range and enables deterministic real-time execution for automotive control loops.
Does the FS32K116LAT0MFMT support CAN-FD?
Yes, the FS32K116LAT0MFMT includes one FlexCAN module that supports CAN-FD per ISO 11898-1, enabling data rates up to 5 Mbps in the flexible data phase. This capability is confirmed in the S32K1xx Data Sheet Rev. 15 feature comparison table and applies directly to the K116 variant. CAN-FD is accessible via dedicated CAN0_TX/CAN0_RX pins in the 48-pin LQFP package.
What security features are implemented in the FS32K116LAT0MFMT?
The FS32K116LAT0MFMT integrates the Cryptographic Services Engine (CSEc), compliant with the Secure Hardware Extension (SHE) specification. It provides AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure boot key management. These functions are accessible via dedicated APIs in the S32 SDK and require no external security co-processor - all security operations execute within the FS32K116LAT0MFMT silicon.
Which development tools support the FS32K116LAT0MFMT?
The FS32K116LAT0MFMT is fully supported by NXP S32 Design Studio (based on Eclipse and GCC), IAR Embedded Workbench, and Arm Keil MDK. Debugging uses standard Serial Wire Debug (SWD) via SWD_CLK/SWD_DIO pins, and evaluation is enabled through the S32K116EVB evaluation board. All toolchains include device-specific startup code, peripheral drivers, and safety libraries aligned with ISO 26262 ASIL-B requirements.
Is the FS32K116LAT0MFMT pin-compatible with other S32K1xx devices?
Yes - the FS32K116LAT0MFMT in the 48-pin LQFP package is pin-compatible with other S32K1xx devices offered in the same LF package, including FS32K118LAT0MFMT and FS32K142LHT0VFMR. This compatibility extends to power, ground, debug, and primary peripheral pins (CAN, UART, SPI, ADC), enabling hardware reuse across variants during platform scaling or qualification.
