Product details
Overview
FS32K118LAT0MLFT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for functional 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 FS32K118LAT0MLFT datasheet, FS32K118LAT0MLFT pinout, FS32K118LAT0MLFT application, or FS32K118LAT0MLFT equivalent, this page provides verified technical context, package mapping to 48-pin LQFP, confirmed low-power peripheral set (LPUART/LPSPI/LPI2C), safety features aligned to ASIL-B, and real-world substitution guidance for automotive ECU designs.
Technical Context
The FS32K118LAT0MLFT implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode - not HSRUN - and lacks Ethernet, SAI, or FlexCAN FD support per S32K11x family constraints. Its memory subsystem includes 128 KB program flash with ECC, 16 KB SRAM, 2 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM configurable as RAM or EEPROM backup.
Power management supports five modes (HSRUN/RUN/STOP/VLPR/VLPS), but HSRUN is disabled on S32K118; only RUN (48 MHz), STOP, and low-power modes are active. Safety mechanisms include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc engine - though CSEc execution requires switching from RUN to VLPR mode per documented operational restriction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LAT0MLFT | Same S32K11x family, 64 KB flash, 16 KB SRAM, identical 48-pin LQFP package and peripheral set | Limited memory headroom for complex diagnostics or larger bootloader stacks | Select when cost-sensitive designs require minimal flash footprint and no future feature expansion |
| MC9S12XEP100MALR | Legacy S12XE architecture, 100 MHz core, no CSEc, no ECC, 5V-tolerant I/O, different toolchain | Requires migration effort; lacks modern safety mechanisms and low-power modes | Consider only for legacy redesigns where pin compatibility and existing software reuse outweigh ASIL-B readiness needs |
Compared with FS32K118LAT0MLFT, FS32K116LAT0MLFT offers identical safety/performance but less flash for bootloader+application separation, while MC9S12XEP100MALR provides higher raw speed but lacks ECC, CSEc, and ASIL-B architectural support - making FS32K118LAT0MLFT the optimal balance of safety, scalability, and production longevity.

FAQ
What is the maximum operating frequency of the FS32K118LAT0MLFT?
The FS32K118LAT0MLFT operates at a maximum frequency of 48 MHz in RUN mode. Unlike higher-tier S32K14x devices, it does not support HSRUN mode (112 MHz) - this limitation is inherent to the S32K11x family architecture and confirmed in the S32K1xx Data Sheet Rev. 15 feature comparison tables. All timing-critical peripherals (ADC, timers, UART) are fully functional at 48 MHz.
Does the FS32K118LAT0MLFT support CAN FD?
No, the FS32K118LAT0MLFT supports only classic CAN 2.0B via its single FlexCAN module. CAN FD capability is explicitly excluded from the S32K11x family per the "Features comparison" section of the datasheet, which lists "FlexCAN (CAN-FD ISO/CD 11898-1)" only for S32K14x and S32K14xW devices. The FS32K118LAT0MLFT requires an external CAN transceiver for physical layer interface but cannot negotiate FD bit rates or payloads.
What package type and pin count does the FS32K118LAT0MLFT use?
The FS32K118LAT0MLFT uses a 48-pin LQFP package (designated "LF" in NXP's ordering nomenclature), with 0.5 mm pitch and 7 mm × 7 mm body size. This matches the S32K11x family's standard 48-pin LQFP option and is pin-to-pin compatible with other S32K11x variants in the same package, enabling design reuse across memory/configurations without PCB changes.
Is the FS32K118LAT0MLFT qualified for automotive applications?
Yes, the FS32K118LAT0MLFT is AEC-Q100 qualified for automotive use and rated for M-grade temperature operation (-40 °C to +125 °C ambient). Its safety features - including System MPU, ECC on flash/SRAM, CRC module, and dual watchdogs (WDOG/EWM) - are architected to support ASIL-B system-level compliance per ISO 26262, making it suitable for body control, junction boxes, and sensor hubs in production vehicles.
What memory resources are available on the FS32K118LAT0MLFT?
The FS32K118LAT0MLFT includes 128 KB of program flash memory with ECC, 16 KB of SRAM with ECC, 2 KB of FlexNVM for EEPROM emulation, and 4 KB of FlexRAM configurable as either additional SRAM or EEPROM backup. These allocations are fixed per the S32K11x family specification and do not scale with package variant - all 48-pin LQFP S32K118 devices share this memory map.
