Product details
Overview
FS32K116BRT0VFMT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 48 MHz, supports -40 °C to 105 °C ambient temperature, integrates 128 KB flash with ECC, 25 KB SRAM (including FlexRAM), and features CSEc security engine, 12-bit ADC, and FlexCAN with LIN support.
For engineers reviewing the FS32K116BRT0VFMT datasheet, FS32K116BRT0VFMT pinout, FS32K116BRT0VFMT application, or FS32K116BRT0VFMT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases in automotive subsystems, and validated alternative parts - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K116BRT0VFMT implements an Arm Cortex-M0+ core with Thumb®-2 ISA, single-cycle MAC, and integrated NVIC supporting up to 43 GPIOs with interrupt capability. Its clock system includes FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL for frequency scaling - though HSRUN mode (112 MHz) is not supported on this variant.
Power management uses PMC with RUN, STOP, VLPR, and VLPS modes; CSEc cryptographic operations and EEPROM emulation require switching from RUN to VLPR mode due to hardware-enforced execution restrictions. Memory protection relies on NXP's system MPU at the crossbar level, not Arm Core MPU.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118BRT0VFMT | 256 KB flash, 32 KB SRAM, same 48-pin LQFP package and V-grade temp range | Higher memory headroom for complex diagnostics, bootloader, and dual-bank firmware updates | Select when >128 KB flash is required for feature-rich body domain software stacks |

FAQ
What is the maximum operating frequency of the FS32K116BRT0VFMT?
The FS32K116BRT0VFMT operates at a maximum frequency of 48 MHz in RUN mode, derived from its 48 MHz Fast Internal RC oscillator (FIRC). Unlike higher-tier S32K1xx variants, it does not support HSRUN mode (112 MHz) or SPLL-based frequency multiplication - confirmed by the S32K1xx Feature Comparison table and ordering code decoding (X = V for 48 MHz).
Does the FS32K116BRT0VFMT support CAN FD?
No, the FS32K116BRT0VFMT does not support CAN FD. It integrates one FlexCAN 2.0B module compatible with standard CAN 2.0A/B protocols and LIN 1.3–2.2A/SAE J2602. CAN FD capability is reserved for S32K14x series parts (e.g., K142/K144) and indicated by ordering option Y = F or A1 - absent in FS32K116BRT0VFMT's part number structure.
What package type and pin count does the FS32K116BRT0VFMT use?
The FS32K116BRT0VFMT uses a 48-pin LQFP package (orderable code "LF"), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This matches the S32K11x family's standardized 48-pin LQFP footprint and is pin-to-pin compatible with other S32K11x variants in the same package, as stated in the S32K1xx Data Sheet Figure 3 and ordering guide.
Is the FS32K116BRT0VFMT qualified for automotive applications?
Yes, the FS32K116BRT0VFMT is AEC-Q100 qualified for automotive use with V-grade temperature rating (-40 °C to +105 °C ambient). It meets ISO 26262 ASIL-B requirements through integrated safety mechanisms including ECC memory, system MPU, CRC module, WDOG/EWM, and lockstep-capable peripherals - documented in the S32K1xx Data Sheet Sections 1.1 and 3.1.
Can the FS32K116BRT0VFMT execute CSEc security functions in RUN mode?
Yes, the FS32K116BRT0VFMT can execute CSEc cryptographic operations (AES, SHA, RNG) in RUN mode at 48 MHz. However, CSEc writes/erases are prohibited in HSRUN mode - irrelevant here since FS32K116BRT0VFMT does not support HSRUN. The device must remain in RUN mode for all CSEc activity, as explicitly noted in the S32K1xx Data Sheet Section 1.1 and Figure 3 footnotes.
