Product details
Overview
FS32K116LFT0VLFR 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, 25 KB SRAM, and CSEc cryptographic engine.
For engineers reviewing the FS32K116LFT0VLFR datasheet, FS32K116LFT0VLFR pinout, FS32K116LFT0VLFR application, or FS32K116LFT0VLFR equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral configuration, and real-world selection guidance for automotive ECU design, LIN-based sensor nodes, and ASIL-B functional safety implementations.
Technical Context
The FS32K116LFT0VLFR implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode with 1.25 DMIPS/MHz performance. It uses NXP's system-level MPU (not Arm Core MPU) for memory protection across AXBS-Lite crossbar masters including core, DMA, and peripherals.
Its power architecture includes five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), with HSRUN disabled on this variant (max 48 MHz). Flash and SRAM employ ECC; security operations require switching from RUN to VLPR mode for CSEc execution or EEPROM emulation via FlexRAM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, 48 MHz max - optimized for deterministic real-time control with minimal power consumption |
| Flash Memory | 128 KB program flash with ECC - enables robust code storage and ASIL-B compliance in automotive environments |
| SRAM | 25 KB total SRAM (including FlexRAM) - supports real-time data buffering and EEPROM emulation without external memory |
| Operating Voltage | 2.7 V to 5.5 V - compatible with 12 V automotive battery systems with wide transient tolerance |
| Temperature Range | -40 °C to 105 °C (V-grade) - qualified for under-hood and cabin-mounted ECUs per AEC-Q100 Grade 2 |

Pinout & Package
FS32K116LFT0VLFR is packaged in a 48-pin LQFP (LF package code), with 43 usable GPIOs, dedicated reset, clock inputs (SOSC, FIRC, SIRC, LPO), and multiple power/ground pins distributed for noise immunity and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled individually; VDDA/VREFH stability directly impacts 12-bit ADC accuracy and comparator DAC linearity |

| SOSC_IN / SOSC_OUT | External crystal oscillator interface | Supports 4–40 MHz crystals; required for high-accuracy RTC and CAN timing when FIRC is insufficient |
| SWD_DIO / SWD_CLK | Serial Wire Debug interface | Two-pin debug port enabling full JTAG/SWD functionality for production programming and field diagnostics |
| LPUART0_RX / LPUART0_TX | Low-power UART channel 0 | Hardware LIN transceiver capable of SAE J2602 and ISO 17987-4 compliant communication at 19.2 kbps |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the maximum operating frequency of the FS32K116LFT0VLFR?
The FS32K116LFT0VLFR operates at up to 48 MHz in RUN mode. Unlike higher-tier S32K14x devices, it does not support HSRUN mode (112 MHz), and its ordering code 'L' explicitly denotes the 48 MHz speed grade with DMA support. This frequency is fully supported across the entire -40 °C to 105 °C ambient range.
Does the FS32K116LFT0VLFR include a floating-point unit (FPU)?
No, the FS32K116LFT0VLFR uses an Arm Cortex-M0+ core without an integrated FPU. Its instruction set and performance profile are optimized for integer-based real-time control tasks common in automotive body electronics. Applications requiring floating-point math must implement software libraries or select an M4F-based variant like FS32K144.
Can the FS32K116LFT0VLFR execute CSEc security functions while running at full speed?
No. The FS32K116LFT0VLFR requires switching from RUN mode to VLPR mode to execute CSEc cryptographic operations or FlexRAM EEPROM emulation. Attempting these functions in RUN mode triggers error flags. This behavior is documented in the S32K1xx datasheet and applies uniformly across all K11x variants.
Which package type is used by the FS32K116LFT0VLFR?
The FS32K116LFT0VLFR uses a 48-pin LQFP package (package code 'LF'). This is confirmed by the ordering code breakdown in the datasheet: 'L' = 48-pin LQFP, and 'F' = LQFP body. It is pin-compatible with other S32K11x devices in the same package, enabling hardware reuse across memory variants.
How many LIN channels does the FS32K116LFT0VLFR support?
The FS32K116LFT0VLFR supports one LPUART module configured as a LIN interface, compliant with LIN protocol versions 1.3, 2.0, 2.1, 2.2A, and SAE J2602. It includes hardware LIN break detection, sync field handling, and checksum calculation - all implemented in dedicated peripheral logic without CPU intervention.
