FAQ
What is the maximum operating frequency of the FS32K116LFT0VLFT?
The FS32K116LFT0VLFT 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 specified across its -40 °C to 105 °C operating range and aligns with AEC-Q100 Grade 2 qualification. The FS32K116LFT0VLFT uses the Arm Cortex-M0+ core, which is optimized for deterministic real-time performance at this frequency band.
Does the FS32K116LFT0VLFT support CAN FD?
No, the FS32K116LFT0VLFT 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 available only in S32K14x series devices (e.g., FS32K142, FS32K144) and selected S32K11x variants marked with ordering option 'F' or 'A1'. The FS32K116LFT0VLFT part number encodes 'L' for 48 MHz speed and 'V' for 3.3 V operation - neither indicates CAN FD support.
What package type and dimensions does the FS32K116LFT0VLFT use?
The FS32K116LFT0VLFT uses a 48-pin LQFP package with 7 mm × 7 mm body size and 0.5 mm lead pitch. It is RoHS-compliant, moisture sensitivity level 3 (MSL3), and qualified for reflow soldering per J-STD-020. This package matches the pinout of other S32K11x devices in the same count, enabling layout reuse across the K116/K118 variants. The 'LF' in the part number explicitly denotes LQFP format.
How much on-chip RAM is available in the FS32K116LFT0VLFT?
The FS32K116LFT0VLFT provides 25 KB of total on-chip RAM: 21 KB of general-purpose SRAM and 4 KB of FlexRAM. The FlexRAM can be configured either as additional SRAM or as EEPROM emulation storage - critical for retaining calibration data and fault logs without external non-volatile memory. All RAM includes error-detection logic, though full ECC is implemented only on flash and main SRAM blocks.
Is the FS32K116LFT0VLFT qualified for automotive applications?
Yes, the FS32K116LFT0VLFT is fully qualified for automotive use under AEC-Q100 Grade 2 (-40 °C to +105 °C), supports ISO 26262 ASIL-B development workflows, and includes safety mechanisms such as ECC on flash/SRAM, System MPU, CRC module, dual watchdogs (WDOG/EWM), and lockstep-capable peripherals. Its 'V' temperature grade and 'F' product status in the part number confirm production release and automotive qualification.
