NXP Semiconductors FS32K116LAT0VFMR

Overview

FS32K116LAT0VFMR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. It operates from 2.7 V to 5.5 V, supports -40 °C to 105 °C ambient temperature (V-grade), delivers up to 48 MHz CPU frequency, and integrates 128 KB flash with ECC, 16 KB SRAM, and CSEc cryptographic engine - deployed in electronic control units requiring ASIL-B compliance.

For engineers reviewing the FS32K116LAT0VFMR datasheet, FS32K116LAT0VFMR pinout, FS32K116LAT0VFMR application, or FS32K116LAT0VFMR equivalent, key selection considerations include its 48-pin LQFP package, HSRUN/RUN/STOP/VLPR power modes, FlexCAN (1 channel, CAN-FD capable), dual 12-bit ADCs (up to 32 channels total), and mandatory mode-switching (to RUN at 80 MHz) for CSEc security operations or EEPROM emulation.

Technical Context

The FS32K116LAT0VFMR implements an Arm Cortex-M0+ core with Thumb®-2 ISA, integrated NVIC, and single-precision FPU - optimized for deterministic real-time response in automotive subsystems. Its clock system includes FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL supporting up to 48 MHz operation in RUN mode.

Power management is handled by the PMC with five defined modes (HSRUN, RUN, STOP, VLPR, VLPS); however, FS32K116LAT0VFMR disables HSRUN mode per its ordering code 'L' (48 MHz with DMA), limiting max CPU speed to 48 MHz and excluding 112 MHz operation. CSEc execution and FlexNVM writes require explicit transition to RUN mode to avoid error flag assertion.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the FS32K116LAT0VFMR?

The FS32K116LAT0VFMR operates at a maximum frequency of 48 MHz, as indicated by the 'L' speed grade in its part number. It does not support HSRUN mode (112 MHz) - unlike higher-grade variants such as 'H' or 'U1'. This fixed 48 MHz clock simplifies PCB design by eliminating high-frequency signal integrity concerns and reduces EMI filtering requirements in cost-sensitive automotive modules.

Does the FS32K116LAT0VFMR support CAN-FD?

Yes, the FS32K116LAT0VFMR includes one FlexCAN module that supports CAN-FD per ISO 11898-1, enabling data rates above 1 Mbps and payloads up to 64 bytes. However, CAN-FD operation requires proper physical layer implementation (e.g., TJA1042T transceiver) and firmware configuration through the S32DS SDK - and is functionally identical to other S32K11x devices with the 'F' feature flag.

Can CSEc security functions be executed in HSRUN mode on the FS32K116LAT0VFMR?

No - the FS32K116LAT0VFMR does not support HSRUN mode at all due to its 'L' speed grade, so this restriction does not apply. CSEc operations (AES encryption, secure boot verification) execute exclusively in RUN mode at 48 MHz. The device asserts error flags if CSEc commands are issued outside RUN mode, ensuring deterministic behavior during safety-critical sequences.

What package type and pin count does the FS32K116LAT0VFMR use?

The FS32K116LAT0VFMR uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant and rated for moisture sensitivity level 3. This package is pin-compatible with other S32K11x devices in the same footprint, enabling scalable design reuse across memory and peripheral variants without PCB revision.

Is the FS32K116LAT0VFMR qualified to AEC-Q100 standards?

Yes, the FS32K116LAT0VFMR is AEC-Q100 qualified for Grade 2 (-40 °C to +105 °C), meeting automotive reliability and stress-test requirements including HTOL, TC, and ESD. Its qualification covers the full device - including flash, SRAM, peripherals, and debug interface - and is documented in NXP's official AEC-Q100 reports available under NDA.
