Product details
Overview
FS32K118LFT0MLHT 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 FS32K118LFT0MLHT datasheet, FS32K118LFT0MLHT pinout, FS32K118LFT0MLHT application, or FS32K118LFT0MLHT equivalent, this page provides verified technical context, package mapping, functional specifications, real-world use scenarios, and validated alternative options aligned with ISO 26262 ASIL-B requirements.
Technical Context
The FS32K118LFT0MLHT implements an Arm Cortex-M0+ core with Thumb®-2 ISA, supporting deterministic real-time execution at up to 48 MHz in RUN mode. It features a dedicated Power Management Controller (PMC) enabling 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, 16 KB SRAM with ECC, 2 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM configurable as SRAM or EEPROM backup. The device uses NXP's system-level Memory Protection Unit (MPU) at the Crossbar Switch level - not Arm Core MPU - to enforce access rights across masters including CPU and DMA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LFT0MLHT | 128 KB flash, 16 KB SRAM, same 48-pin LQFP package, but only one 12-bit ADC module (vs. two in K118) | Limited analog channel count - suitable for simpler LIN nodes without multi-sensor acquisition | Select when ADC channel count and FlexNVM size are non-critical; identical pinout and software compatibility reduce redesign effort |

FAQ
What is the maximum operating frequency of the FS32K118LFT0MLHT?
The FS32K118LFT0MLHT 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 characterized across the -40 °C to +125 °C ambient range and aligns with its Arm Cortex-M0+ core architecture and M-grade thermal qualification.
Does the FS32K118LFT0MLHT include hardware encryption capabilities?
Yes, the FS32K118LFT0MLHT integrates the Cryptographic Services Engine (CSEc), a hardware security module compliant with SHE (Secure Hardware Extension). It supports AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure key storage - all essential for secure boot and authenticated firmware updates in automotive systems.
What package type and pin count does the FS32K118LFT0MLHT use?
The FS32K118LFT0MLHT uses a 48-pin LQFP package (package code LF), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This package is pin-compatible with other S32K11x variants in the same footprint, including FS32K116LFT0MLHT, enabling scalable design reuse.
Is the FS32K118LFT0MLHT qualified for automotive safety standards?
Yes, the FS32K118LFT0MLHT is designed to support ISO 26262 ASIL-B applications. It includes safety mechanisms such as ECC on flash and SRAM, system-level MPU, CRC module, dual watchdogs (WDOG and EWM), lockstep-ready peripherals, and failure reporting via error flags - all documented in NXP's S32K1xx Functional Safety Manual.
Can the FS32K118LFT0MLHT support CAN FD communication?
No, the FS32K118LFT0MLHT does not support CAN FD. Its FlexCAN module implements classic CAN 2.0B only. CAN FD capability is available in higher-tier S32K14x devices (e.g., FS32K142, FS32K144) and requires explicit ordering option 'F' or 'A1' in the part number - which FS32K118LFT0MLHT does not include.
