For engineers reviewing the FS32K116LFT0VFMR datasheet, FS32K116LFT0VFMR pinout, FS32K116LFT0VFMR application, or FS32K116LFT0VFMR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases in automotive subsystems, and validated alternative options for design continuity and sourcing resilience.
Technical Context
The FS32K116LFT0VFMR implements a single-core Arm Cortex-M0+ CPU with Thumb®-2 ISA, operating at up to 48 MHz in RUN mode and supporting HSRUN mode only on M4F variants - not applicable here. It uses FIRC (48 MHz) as primary clock source and includes SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) for flexible timing.
Its memory subsystem comprises 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, 25 KB total SRAM (including 4 KB FlexRAM), and 2 KB code cache. Safety features include System MPU, CRC module, WDOG, EWM, and CSEc - all active and validated for ASIL-B capable systems per ISO 26262.

It does not support HSRUN mode (112 MHz), which is exclusive to M4F-based S32K14x devices. This 48 MHz clock enables deterministic real-time response for body control tasks while maintaining low power consumption and thermal stability.
Does the FS32K116LFT0VFMR support CAN FD?
No, the FS32K116LFT0VFMR includes one FlexCAN 2.0B module without CAN FD capability. CAN FD support begins with S32K142 and higher variants (e.g., FS32K142LFT0VFM). For FS32K116LFT0VFMR, the FlexCAN module supports standard CAN 2.0B up to 1 Mbps and includes LIN protocol emulation via LPUART, making it suitable for legacy vehicle networks.
What package type and pin count does FS32K116LFT0VFMR use?
FS32K116LFT0VFMR uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), designated by the "LF" suffix in the part number. This package is pin-compatible with other S32K11x devices in the same footprint, enabling design reuse across memory and peripheral variants without PCB redesign.
Is the FS32K116LFT0VFMR qualified for automotive temperature grades?
Yes, FS32K116LFT0VFMR is V-grade qualified for operation from -40 °C to +105 °C ambient temperature, meeting AEC-Q100 Grade 2 requirements. Its junction temperature rating reaches 125 °C in RUN mode, ensuring reliability in under-hood and cabin-mounted electronic control units subject to thermal cycling and extended service life.
How does the CSEc security engine function in FS32K116LFT0VFMR?
The Cryptographic Services Engine (CSEc) in FS32K116LFT0VFMR provides hardware-accelerated AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure boot key management. It operates independently of the CPU, enabling secure firmware authentication and OTA update verification without compromising real-time performance or increasing software overhead.
