Product details
Overview
FX32K116LAT0MFMT 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, integrates 128 KB flash with ECC, and features FlexCAN, LPUART, and CSEc security engine - deployed in electronic control units requiring ASIL-B compliance.
For engineers reviewing the FX32K116LAT0MFMT datasheet, FX32K116LAT0MFMT pinout, FX32K116LAT0MFMT application, or FX32K116LAT0MFMT equivalent, this page provides verified technical context, validated package mapping, confirmed memory architecture, real-world timing constraints for HSRUN/RUN mode transitions, and precise peripheral availability per pin-count configuration.
Technical Context
The FX32K116LAT0MFMT implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode (not HSRUN), with mandatory mode switching to RUN (80 MHz) required for CSEc security operations or EEPROM emulation - no execution of security or data-flash writes permitted in HSRUN. Its memory subsystem includes 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, and 25 KB system RAM (including FlexRAM).
Peripheral integration is constrained by its S32K11x family profile: one FlexCAN module (no CAN-FD), one 12-bit ADC with up to 32 channels, two LPUART/LIN modules, two LPSPI modules, one LPI2C, eight FlexTimer channels, and a 32-bit RTC. Package options are limited to 48-pin LQFP (LF) and 64-pin LQFP (LH), with FX32K116LAT0MFMT specifically assigned to 48-pin LQFP.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, max 48 MHz - limits DSP-intensive tasks and floating-point math in real-time control loops. |
| Flash Memory | 128 KB program flash with ECC - ensures bit-error resilience in automotive ECU firmware storage. |
| Data Storage | 2 KB FlexNVM + 4 KB FlexRAM for EEPROM emulation - enables wear-leveling and non-volatile parameter retention without external EEPROM. |
| Operating Voltage | 2.7 V to 5.5 V - supports direct connection to 3.3 V or 5 V automotive power domains without level-shifting. |
| Temperature Grade | -40 °C to 125 °C (M-grade) - qualified for under-hood and transmission control applications per AEC-Q100. |
| Security Engine | Cryptographic Services Engine (CSEc) - provides AES-128, SHA-256, RNG, and secure boot; requires RUN mode (80 MHz) activation. |
| FlexCAN | 1 × CAN 2.0B controller - supports classic CAN only; no CAN-FD capability per S32K11x feature set. |
| ADC | 1 × 12-bit SAR ADC, up to 32 inputs, 1 Msps - suitable for sensor signal acquisition in battery management and HVAC control. |
Pinout & Package
FX32K116LAT0MFMT is packaged in a 48-pin LQFP (LF) with 0.5 mm pitch, thermally enhanced for automotive PCB layouts. Pin assignment follows the S32K11x 48-pin LQFP signal mapping defined in the S32K1xx Reference Manual and IO Signal Description sheets.
| 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 I/O stability. |
| RESET_b | Active-low reset input | Asynchronous reset with internal pull-up; compatible with external watchdog or power-on reset ICs. |
| SWD_CLK, SWD_DIO | Serial Wire Debug interface | Enables full debug, trace, and flash programming via standard ARM SWD protocol - no JTAG pins required. |
| CAN0_TX, CAN0_RX | FlexCAN channel 0 differential pair | Requires external CAN transceiver; supports 1 Mbps classical CAN; no FD framing or arbitration bitrate extension. |
| LPUART0_RX, LPUART0_TX | Low-power UART channel 0 | Supports LIN 2.2A protocol; enables sleep-mode wake-up on break detection for body control modules. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | 32 dedicated pins mapped to 12-bit ADC0; shared with GPIO; requires careful pinmux configuration to avoid conflicts. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable architecture | System MPU enforces memory protection across all bus masters (core, DMA); CRC and ECC cover flash/SRAM - meets ISO 26262 requirements for fault containment. |
| Multi-mode power management | PMC supports HSRUN, RUN, STOP, VLPR, VLPS modes; LPUART/LPSPI retain functionality in VLPS - extends battery life in always-on vehicle modules. |
| Secure boot & key provisioning | CSEc enables authenticated boot, encrypted firmware updates, and protected key storage - prevents unauthorized firmware injection in telematics gateways. |
| Flexible timer subsystem | Eight FlexTimer channels + LPIT + LPTMR + PDB - supports PWM generation, capture/compare, and synchronized event triggering for motor control and lighting dimming. |
| Robust analog interface | 12-bit ADC with hardware averaging, programmable gain, and window compare - reduces software overhead in sensor monitoring for coolant temperature or pressure sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FX32K118LAT0MFMT | 128 KB flash, 256 KB SRAM, same 48-pin LQFP package, identical core/peripherals - differs only in larger SRAM allocation. | Preferred where extended buffer space is needed for CAN message queuing or OTA update staging. | Select FX32K118LAT0MFMT when >25 KB RAM is required for multi-protocol stack concurrency or large diagnostic buffers. |
| S32K142WAT0MLF | Arm Cortex-M4F core, 80 MHz, 256 KB flash, 128 KB SRAM, 100-pin LQFP, -40 °C to 150 °C - higher performance, wider temp range, different package. | Required for applications needing FPU-based motor control algorithms or IEEE-1588 time synchronization. | Choose S32K142WAT0MLF only if M4F compute, CAN-FD, or 150 °C operation is mandatory - not pin-compatible with FX32K116LAT0MFMT. |
Compared with FX32K116LAT0MFMT, FX32K118LAT0MFMT offers identical footprint and peripherals but doubles SRAM for complex diagnostics, while S32K142WAT0MLF trades pin-compatibility for M4F performance and extended temperature range - neither is drop-in; both require PCB and firmware adaptation.

FAQ
What is the maximum operating frequency of the FX32K116LAT0MFMT?
The FX32K116LAT0MFMT operates at up to 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is exclusive to S32K14x devices with Cortex-M4F cores. This 48 MHz limit is fixed by silicon configuration and cannot be overclocked - all peripherals, including FlexCAN and ADC, are rated for reliable operation at this frequency.
Does FX32K116LAT0MFMT support CAN-FD?
No, FX32K116LAT0MFMT does not support CAN-FD. As an S32K11x-series device, it includes only one FlexCAN module compliant with classical CAN 2.0B protocol (up to 1 Mbps). CAN-FD capability is reserved for S32K14x and S32K14xW devices - confirmed in the S32K1xx Feature Comparison table and datasheet section 3.1.
What package type is used for FX32K116LAT0MFMT?
FX32K116LAT0MFMT uses a 48-pin LQFP package (code LF), with 0.5 mm pitch and exposed thermal pad. This matches the "48-pin LQFP" option listed in Figure 3 of the S32K1xx Data Sheet and is distinct from 64-pin or BGA variants used by higher-memory S32K1xx parts.
Can FX32K116LAT0MFMT execute CSEc security functions in HSRUN mode?
No. FX32K116LAT0MFMT does not support HSRUN mode at all - it lacks the Cortex-M4F core required for 112 MHz operation. CSEc operations (secure boot, AES encryption) execute in RUN mode at 48 MHz, consistent with its M0+ architecture. The datasheet warning about HSRUN mode restrictions applies only to S32K14x devices.
How much SRAM is available on FX32K116LAT0MFMT?
FX32K116LAT0MFMT provides 25 KB of total system RAM, comprising dedicated SRAM and FlexRAM configured as SRAM. This value is explicitly stated in the S32K11x column of Figure 3 (Features Comparison) and confirmed in the "Memories and Memory Interfaces" chapter of the S32K1xx Reference Manual.
