Product details
Overview
FX32K118LAT0MLHT 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, 16 KB SRAM, and CSEc cryptographic engine.
For engineers reviewing the FX32K118LAT0MLHT datasheet, FX32K118LAT0MLHT pinout, FX32K118LAT0MLHT application, or FX32K118LAT0MLHT 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 (5 March 2026).
Technical Context
The FX32K118LAT0MLHT implements a single-core Arm Cortex-M0+ processor without FPU, optimized for deterministic real-time control in ASIL-B capable systems. It features a 48 MHz maximum operating frequency in RUN mode, fixed 128 KB program flash with ECC, and 16 KB SRAM - all aligned with ISO 26262 functional safety requirements.
Its peripheral set includes one LPUART/LIN module, one LPSPI, one LPI2C, one FlexCAN (CAN-FD capable), one 12-bit ADC (up to 16 channels), one FlexTimer (8 channels), and low-power timers (LPTMR, LPIT). Power management supports HSRUN, RUN, STOP, VLPR, and VLPS modes - though HSRUN is disabled on K118 variants per datasheet Figure 3.
Key Specifications

| Flexible Timer System | FlexTimer0 with 8 channels supports PWM generation, input capture, and quadrature decoding - ideal for motor position sensing and LED dimming. |
Applications
| Body Control Module (BCM) | Door Module Controller |
|---|---|
Use Scenario: Centralized management of lighting, window lift, mirror adjustment, and door lock actuation in modern vehicles. IC Role / Device Role / Timing Role: Primary MCU executing LIN slave protocol, driving GPIO-controlled relays and H-bridges, and managing EEPROM-emulated configuration storage. Use Value: 48 MHz real-time response ensures <10 ms latency for window anti-pinch detection and seamless multi-node LIN communication. |
Use Scenario: Local intelligence in each vehicle door for independent control of window motors, interior lights, and proximity sensors. IC Role / Device Role / Timing Role: Standalone LIN node with integrated ADC for current sensing, FlexTimer for PWM motor control, and CSEc for secure key exchange with BCM. Use Value: On-chip CSEc and 128 KB flash eliminate need for external secure element - reducing BOM cost and PCB footprint. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FX32K116LAT0MLHT | 64 KB flash, 16 KB SRAM, same core/package - lacks FlexCAN and second LPUART. | Suitable for simpler LIN-only nodes without CAN connectivity or dual-bus diagnostics. | Select when CAN-FD is unnecessary and cost optimization is prioritized over future feature scalability. |
| FX32K142WAT0MLHT | Arm Cortex-M4F core, 256 KB flash, 32 KB SRAM, 80 MHz, extended temp (−40 °C to +150 °C), Ethernet MAC. | Targeted at higher-performance gateway or domain controller roles requiring DSP, FPU, or network bridging. | Choose only if M4F compute capability, larger memory, or IEEE-1588 Ethernet are required - not a drop-in replacement. |
Compared with FX32K116LAT0MLHT, the FX32K118LAT0MLHT adds FlexCAN and dual LPUART for enhanced diagnostics and redundancy; versus FX32K142WAT0MLHT, it trades M4F performance and Ethernet for lower cost, smaller footprint, and proven M0+ determinism in body electronics.

This package is pin-compatible with other 48-pin S32K11x variants like FX32K116LAT0MLHT, enabling shared PCB layouts across product tiers.
Can the FX32K118LAT0MLHT support CAN-FD communication?
Yes, the FX32K118LAT0MLHT includes one FlexCAN module with CAN-FD capability, as confirmed in the Feature Comparison table (Figure 3) and Section 1.1 Communications Interfaces. It supports data rates up to 5 Mbps in FD mode and is fully compatible with ISO 11898-1:2015, enabling high-bandwidth diagnostics and ECU reprogramming.
Is the FX32K118LAT0MLHT qualified for automotive applications?
Yes, the FX32K118LAT0MLHT is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C) and designed to meet ISO 26262 ASIL-B requirements. Its safety features - including ECC on flash/SRAM, system MPU, dual watchdog (WDOG + EWM), and CRC module - are explicitly documented in Sections 1.1 and 3.1 of the S32K1xx Data Sheet Rev. 15.
