Product details
Overview
FX32K116LAT0MFMR 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 FX32K116LAT0MFMR datasheet, FX32K116LAT0MFMR pinout, FX32K116LAT0MFMR application, or FX32K116LAT0MFMR equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain support tailored for automotive ECU design, LIN-based sensor nodes, and ASIL-B compliant systems.
Technical Context
The FX32K116LAT0MFMR implements a single-core Arm Cortex-M0+ processor with Thumb®-2 ISA, 1.25 DMIPS/MHz performance, and integrated Digital Signal Processing extensions. It features a dedicated Power Management Controller (PMC) supporting five low-power modes - HSRUN, RUN, STOP, VLPR, and VLPS - with clock gating per peripheral domain.
Its memory subsystem includes 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, 4 KB FlexRAM configurable as SRAM or EEPROM, and 25 KB total system RAM. The device uses a crossbar switch (AXBS-Lite) for deterministic bus arbitration between core, eDMA, and peripherals including LPUART, LPSPI, LPI2C, FlexCAN, and 12-bit ADC.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | System MPU enforces memory region access rights across core and DMA; ECC on flash/SRAM meets ISO 26262 requirements |
| Low-Power Flexibility | Five power modes (VLPR/VLPS/STOP/RUN/HSRUN); LPUART/LPSPI retain functionality in VLPR - extends battery life in always-on modules |
| Secure Boot & Runtime Security | CSEc implements SHE v3.1 crypto suite; supports authenticated boot, encrypted firmware updates, and key lifecycle management |
| Automotive Communication Stack | Single FlexCAN module with CAN 2.0B protocol support and LIN-compliant LPUART - eliminates need for external transceivers in body control units |
| Analog Integration | 12-bit SAR ADC (1 Msps, 16-channel mux), analog comparator with integrated 8-bit DAC - enables closed-loop current/voltage sensing without external signal conditioning |
Applications
| Body Control Module (BCM) | Door Module Control |
|---|---|
Use Scenario: Centralized control of lighting, window lift, mirror adjustment, and door lock actuation in modern vehicle platforms. IC Role / Device Role / Timing Role: Primary MCU executing real-time PWM for motor drivers, LIN communication with slave nodes, and fault-safe diagnostics. Use Value: Integrated CSEc enables secure OTA updates; 48 MHz M0+ core delivers deterministic response under 100 µs for safety-critical lock/unlock sequences. |
Use Scenario: Localized intelligence in power door modules managing window anti-pinch, express up/down, and proximity-based auto-close. IC Role / Device Role / Timing Role: Sensor fusion hub aggregating Hall effect, current sense, and position feedback; executes torque-limited motor control via FTM PWM outputs. Use Value: On-chip 12-bit ADC and comparator with DAC reduce BOM cost; VLPR mode draws <10 µA during standby - extends battery runtime in keyless entry scenarios. |
| Engine Coolant Heater Control | Seat Heating System |
Use Scenario: Regulated 12 V resistive heating control for cold-start engine preheating in EVs and hybrids. IC Role / Device Role / Timing Role: Safety monitor interfacing with thermistors, relays, and current shunts; performs thermal runaway detection and shutdown within 5 ms. Use Value: ASIL-B compliant MPU and ECC memory ensure fail-safe operation; CSEc validates heater firmware integrity before execution. |
Use Scenario: Multi-zone seat heating with independent temperature regulation per element using PWM-driven resistive traces. IC Role / Device Role / Timing Role: Thermal manager reading NTC sensors, driving MOSFET half-bridges, and communicating status over LIN to HVAC ECU. Use Value: 48-pin LQFP provides sufficient GPIO for 6+ heater zones; integrated LPUART eliminates external LIN transceiver - simplifies layout and improves EMC robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K118LAT0MFMR | 128 KB flash, 64 KB SRAM, same 48-pin LQFP, identical peripherals but adds second LPUART and enhanced CSEc key storage | Preferred for designs requiring dual-LIN networks or extended secure key vault capacity | Select when additional UART channels or larger secure memory are required; pin-compatible drop-in upgrade path |
| MC9S12XEP100MALR | Legacy S12X architecture, 50 MHz, 1 MB flash, no CSEc, no FlexCAN FD, requires external oscillator | Suitable for brownfield upgrades where legacy toolchain and peripheral compatibility are mandatory | Choose only for migration projects retaining existing S12X software stack; lacks modern security and low-power features |
Compared with FX32K116LAT0MFMR, S32K118LAT0MFMR offers higher RAM and dual-LIN at identical footprint and voltage range, while MC9S12XEP100MALR provides backward compatibility at the cost of missing ASIL-B infrastructure and cryptographic acceleration.

FAQ
What is the maximum operating frequency of FX32K116LAT0MFMR?
The FX32K116LAT0MFMR operates at up to 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is reserved for M4F-based S32K14x devices. This 48 MHz limit is fully supported across its entire -40 °C to +125 °C operating range and aligns with its Arm Cortex-M0+ core architecture and automotive qualification profile.
Does FX32K116LAT0MFMR support CAN-FD?
No, FX32K116LAT0MFMR includes one FlexCAN module compliant with CAN 2.0B only. CAN-FD support is exclusive to S32K14x series devices (e.g., S32K144, S32K146) and requires specific ordering options marked with 'F' or 'A1' in the part number suffix. The FX32K116LAT0MFMR datasheet explicitly lists CAN 2.0B as its sole CAN protocol capability.
What package type and pin count does FX32K116LAT0MFMR use?
FX32K116LAT0MFMR uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This is confirmed in the S32K1xx Datasheet Rev. 15 Feature Comparison table and matches the 'LF' package code in its orderable part number structure. All 48-pin LQFP variants in the S32K11x family are pin-to-pin compatible.
Is FX32K116LAT0MFMR qualified for automotive applications?
Yes, FX32K116LAT0MFMR is AEC-Q100 Grade 1 qualified (-40 °C to +125 °C) and designed to meet ISO 26262 ASIL-B requirements. Its integrated System MPU, ECC on flash and SRAM, CSEc cryptographic engine, and dual watchdog (WDOG + EWM) fulfill key safety mechanisms mandated for automotive body electronics and powertrain auxiliary functions.
Can FX32K116LAT0MFMR execute CSEc operations in HSRUN mode?
No - FX32K116LAT0MFMR does not support HSRUN mode at all, as it lacks the Arm Cortex-M4F core required for 112 MHz operation. CSEc operations (e.g., AES encryption, secure boot validation) execute reliably in its native RUN mode at 48 MHz, with no mode-switching requirement. The HSRUN restriction noted in the datasheet applies only to M4F-equipped S32K14x devices.
