Product details
Overview
FS32K116LAT0MFMR 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.
For engineers reviewing the FS32K116LAT0MFMR datasheet, FS32K116LAT0MFMR pinout, FS32K116LAT0MFMR application, or FS32K116LAT0MFMR equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options - all aligned to S32K1xx Rev. 15 data sheet specifications and orderable part constraints.
Technical Context
The FS32K116LAT0MFMR implements a single-core Arm Cortex-M0+ CPU with Thumb®-2 ISA support, optimized for deterministic real-time operation in ASIL-B capable systems. It includes integrated NVIC, system MPU for crossbar-level memory protection, and dedicated low-power peripherals including LPUART, LPSPI, and LPI2C - all with DMA support and configurable wake-up capability.
Its clock architecture combines FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) sources, feeding a scalable SPLL for precise timing control. Power management supports five modes (HSRUN, RUN, STOP, VLPR, VLPS), with HSRUN disabled for CSEc/EEPROM operations - requiring mode switch to RUN (48 MHz) for secure writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, Thumb®-2 ISA, no FPU - suitable for deterministic control tasks without floating-point overhead. |
| Max Operating Frequency | 48 MHz (L-speed grade) - enables real-time response in LIN gateway and sensor fusion applications. |

Pinout & Package
FS32K116LAT0MFMR is housed in a 48-pin LQFP (Lead-Free, RoHS-compliant) package with 0.5 mm pitch and exposed thermal pad. Pin assignment follows S32K11x family layout per Reference Manual IO Signal Description sheets.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| LPUART0_RX / LPUART0_TX | Low-power UART interface | Enables LIN 2.x protocol implementation with automatic sync-break detection and slave node addressing. |
Key Features
| Feature | Design Value |
|---|---|
| System MPU with Crossbar Protection | Enforces memory access rights per master (CPU/DMA), preventing unauthorized peripheral or memory region access - foundational for ISO 26262 ASIL-B compliance. |
| Low-Power Peripheral Operation | LPUART, LPSPI, and LPI2C retain full functionality in VLPR/VLPS modes - enabling battery-powered wake-on-event designs with sub-10 µA sleep current. |
| FlexRAM Configuration | 4 KB FlexRAM configurable as SRAM or EEPROM emulation - eliminates need for external non-volatile storage in calibration data logging. |
| Real-Time Counter (RTC) | 32-bit RTC with 32.768 kHz crystal input and tamper-detection capability - supports time-stamped diagnostics and secure firmware update scheduling. |
| Error-Correcting Code (ECC) | ECC applied to flash and SRAM detects and corrects single-bit errors - essential for functional safety in automotive control units operating over 15-year lifetimes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LAT0MFMR | 128 KB flash, 25 KB SRAM, same 48-pin LQFP package, but adds second LPUART and second 12-bit ADC module. | Supports dual-sensor redundancy or additional LIN sub-bus without external bridge IC. | Select when needing extra serial interface or analog channel count without changing PCB layout. |
| MC9S12XEP100MALR | Legacy S12XE 16-bit core, 1 MB flash, no CSEc, no FlexCAN FD, requires external oscillator and lacks ECC memory protection. | Used in legacy ECU redesigns where toolchain continuity outweighs safety certification needs. | Choose only for brownfield projects with existing S12 software investment and no ASIL-B requirement. |
Compared with FS32K116LAT0MFMR, FS32K118LAT0MFMR offers expanded peripheral count within identical packaging and thermal specs, while MC9S12XEP100MALR represents a legacy architecture lacking modern safety features - making FS32K116LAT0MFMR the optimal balance of cost, certification readiness, and integration density for new body electronics designs.

FAQ
What is the maximum operating frequency of the FS32K116LAT0MFMR?
The FS32K116LAT0MFMR operates at a maximum frequency of 48 MHz in RUN mode, as defined by its "L" speed grade in the ordering code. This frequency is fixed - unlike higher-tier S32K14x devices, it does not support HSRUN mode or dynamic frequency scaling beyond 48 MHz. All timing-critical peripherals, including FlexTimer and LPUART, are fully functional at this clock rate, and the device remains qualified across its full -40 °C to +125 °C ambient temperature range at this speed.
Does the FS32K116LAT0MFMR support CAN FD?
No, the FS32K116LAT0MFMR does not support CAN FD. Its FlexCAN module is compliant only with classical CAN 2.0B protocol, supporting bit rates up to 1 Mbps. The "F" feature code in the ordering nomenclature applies only to S32K14x-series parts; FS32K116LAT0MFMR belongs to the S32K11x family, which lacks CAN FD hardware capability. For CAN FD requirements, engineers must select an S32K142 or higher variant - the FS32K116LAT0MFMR remains appropriate for LIN-centric or classical CAN networks in body electronics.
What package type and pin count does the FS32K116LAT0MFMR use?
The FS32K116LAT0MFMR uses a 48-pin LQFP package (package code "LF"), with 0.5 mm pitch and RoHS-compliant lead-free finish. This matches the pinout defined for the S32K11x family in the Reference Manual's IO Signal Description sheets. The 48-pin LQFP provides 43 GPIOs, including dedicated LPUART, LPSPI, and FlexCAN signals, and is compatible with standard reflow soldering processes used in automotive PCB manufacturing.
Is the FS32K116LAT0MFMR qualified for automotive safety standards?
Yes, the FS32K116LAT0MFMR is designed and qualified to support ISO 26262 ASIL-B applications. It includes hardware safety mechanisms such as ECC on flash and SRAM, System MPU for memory protection, CRC module, internal watchdog (WDOG), external watchdog monitor (EWM), and lockstep-capable peripherals. While the MCU itself is not certified as a standalone ASIL-B component, its integrated features enable system-level ASIL-B compliance when implemented per NXP's safety manual and FMEDA reports - making FS32K116LAT0MFMR suitable for body control, lighting, and HVAC nodes.
Can the FS32K116LAT0MFMR execute CSEc cryptographic operations at full speed?
No - CSEc (Cryptographic Services Engine) operations cannot be executed while the FS32K116LAT0MFMR runs in HSRUN mode, because HSRUN mode is not supported on this part. However, even in its maximum RUN mode (48 MHz), CSEc execution is permitted and fully functional. The datasheet explicitly states that CSEc or EEPROM write/erase triggers error flags if attempted above 48 MHz; since FS32K116LAT0MFMR is limited to 48 MHz, this constraint does not impact normal operation - all security functions operate reliably at its rated frequency.
