Product details
Overview
FX32K116LAT0MLFR 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 FX32K116LAT0MLFR datasheet, FX32K116LAT0MLFR pinout, FX32K116LAT0MLFR application, or FX32K116LAT0MLFR equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for automotive ECU design, LIN-based sensor nodes, and ASIL-B functional safety implementations.
Technical Context
The FX32K116LAT0MLFR implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode. It features a system-level Memory Protection Unit (MPU) integrated into the crossbar switch-not core-internal-enabling ASIL-B–capable memory region access control across CPU, DMA, and peripherals.
Its peripheral set includes one LPUART/LIN module, one LPSPI, one LPI2C, one FlexCAN (CAN-FD capable), one 12-bit ADC (up to 32 channels), one analog comparator with 8-bit DAC, and low-power timers (LPTMR, LPIT). Flash and SRAM both implement ECC, and security operations require switching from HSRUN to RUN mode due to hardware-enforced execution isolation.

FAQ
What is the maximum operating frequency of FX32K116LAT0MLFR?
The FX32K116LAT0MLFR 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 clock is generated from the FIRC oscillator or external crystal via the SPLL, and is fully qualified across the -40 °C to +125 °C temperature range.
Does FX32K116LAT0MLFR support CAN-FD?
Yes, FX32K116LAT0MLFR includes one FlexCAN module that supports CAN-FD protocol per ISO 11898-1, enabling data rates up to 5 Mbps and payloads up to 64 bytes. The CAN-FD controller is fully integrated with the CSEc engine for secure message authentication and supports both classic CAN and FD frames on the same bus.
What package type is used for FX32K116LAT0MLFR?
FX32K116LAT0MLFR uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible with other S32K11x variants in the same footprint, allowing flexible BOM management across memory and feature variants without PCB redesign.
How does the CSEc engine function in FX32K116LAT0MLFR?
The CSEc engine in FX32K116LAT0MLFR provides hardware-accelerated AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure key provisioning. It operates independently of the CPU and enforces strict separation: security operations must be executed in RUN mode (not HSRUN), and violations trigger hardware fault responses.
Is FX32K116LAT0MLFR qualified for automotive safety standards?
Yes, FX32K116LAT0MLFR is designed to support ASIL-B compliance per ISO 26262. Its safety features include ECC on flash and SRAM, system-level MPU with crossbar enforcement, lockstep-capable peripherals, CRC modules, dual watchdogs (WDOG and EWM), and failure reporting via the Fault Collection and Control Unit (FCCU).
