FAQ
What is the maximum operating frequency of the FS32K118LFT0MLFT?
The FS32K118LFT0MLFT 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 48 MHz clock is generated from the FIRC oscillator or external crystal via the SPLL, and is fully validated across its -40 °C to +125 °C operating range. The FS32K118LFT0MLFT datasheet confirms this limit in the "Features" and "Electrical Characteristics" sections.
Does the FS32K118LFT0MLFT support CAN FD?
No, the FS32K118LFT0MLFT does not support CAN FD. It integrates a single FlexCAN module compliant with ISO 11898-1 (classical CAN), supporting up to 1 Mbps. CAN FD capability is reserved for S32K14x devices (e.g., FS32K142, FS32K144) and requires specific ordering options denoted by 'F' or 'A1' in the part number suffix. The FS32K118LFT0MLFT datasheet explicitly lists only classical CAN in its peripheral comparison table.
What package type and pin count does FS32K118LFT0MLFT use?
The FS32K118LFT0MLFT uses a 48-pin LQFP package (package code 'LF'), measuring 7 mm × 7 mm with 0.5 mm pitch. This matches the S32K11x family's standard 48-pin LQFP option and is pin-compatible with other S32K11x variants in the same package, such as FS32K116LFT0MLFT. The 'LFT0MLFT' suffix confirms LF (LQFP-48), M (125 °C grade), and T (tape-and-reel) packaging.
Is the FS32K118LFT0MLFT qualified for automotive safety standards?
Yes, the FS32K118LFT0MLFT is designed to support ASIL-B compliance per ISO 26262. It includes integrated safety mechanisms: ECC on flash and SRAM, system MPU enforcing memory access rights at the crossbar level, CRC module, dual watchdogs (WDOG and EWM), and lockstep-capable peripherals. While the MCU itself is not certified, its architecture and documented failure modes enable ASIL-B system-level certification when used per NXP's safety manual and reference designs.
What debug interface does FS32K118LFT0MLFT support?
The FS32K118LFT0MLFT supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins - a 2-pin interface compatible with standard ARM debug probes (e.g., SEGGER J-Link, NXP LPC-Link2). It also supports JTAG for legacy tooling, though SWD is preferred for reduced pin count and full functionality including breakpoints, watchpoints, and ITM trace. The FS32K118LFT0MLFT datasheet specifies SWD as the primary debug method in the "Debug Functionality" section.
