Product details
Overview
FS32K116LFT0MLFR 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 +125 °C ambient temperature (M-grade), delivers up to 48 MHz CPU frequency, integrates 128 KB flash with ECC, and features CSEc cryptographic engine for secure boot and key management in ECU applications.
For engineers reviewing the FS32K116LFT0MLFR datasheet, FS32K116LFT0MLFR pinout, FS32K116LFT0MLFR application, or FS32K116LFT0MLFR equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral configuration, real-world use-value analysis, and two rigorously cross-referenced alternative parts - all derived exclusively from NXP's official S32K1xx Data Sheet Rev. 15 (5 March 2026) and orderable part number documentation.
Technical Context
The FS32K116LFT0MLFR implements an Arm Cortex-M0+ core optimized for deterministic real-time control in ASIL-B capable systems. It uses a single 48 MHz clock domain (FIRC-based, no SPLL), supports five low-power modes (HSRUN not available), and relies on NXP's system-level MPU - not Arm's core MPU - for memory protection across AXBS-Lite crossbar masters including DMA and peripherals.
Its analog subsystem includes one 12-bit ADC (1 Msps, up to 32 channels), one analog comparator with integrated 8-bit DAC, and dedicated LPO/RTC_CLKIN timing inputs. Communication is limited to one FlexCAN (CAN-FD capable), two LPUART/LIN modules, two LPSPI, one LPI2C, and FlexIO for protocol emulation - all with DMA support and low-power wake-up capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 48 MHz max - fixed-frequency operation without HSRUN mode; suitable for deterministic timing-critical tasks without PLL complexity. |
| Flash Memory | 128 KB program flash with ECC - enables robust code storage and error detection in harsh automotive environments. |
| RAM | 25 KB SRAM (including FlexRAM) - sufficient for real-time control stacks, CAN message buffers, and safety monitor variables. |
| Operating Voltage | 2.7 V to 5.5 V - compatible with wide-range 12 V automotive battery systems including cold-crank conditions. |
| Temperature Grade | -40 °C to +125 °C (M-grade) - qualified for under-hood and transmission control module placement. |
| Security | Cryptographic Services Engine (CSEc) - supports AES-128, SHA-256, RNG, and secure boot; requires RUN mode (not HSRUN) for execution. |
| ADC | 12-bit SAR ADC, 1 Msps, up to 32 channels - enables high-resolution sensor acquisition for throttle position, temperature, and pressure monitoring. |
| FlexCAN | 1 × CAN-FD controller (ISO 11898-1) - supports data rates up to 5 Mbps for modern vehicle network upgrades. |
Pinout & Package
FS32K116LFT0MLFR is packaged in a 48-pin LQFP (LF package code), with 43 GPIOs, 4 dedicated ADC reference pins (VREFH/VREFL), 3 power domains (VDD/VDDA/VSS), and dedicated debug interface pins (SWD_CLK/SWD_IO/NMI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VSS | Power supply and ground | Separate analog/digital supplies require PCB decoupling per AN5032; differential tolerance ±0.1 V ensures ADC accuracy. |
| SWD_CLK, SWD_IO | Serial Wire Debug interface | Enables non-intrusive debugging and flash programming without JTAG pins; supports trace via ITM/DWT. |
| RTC_CLKIN | 32 kHz external RTC clock input | Allows precise timekeeping using external crystal; critical for wake-up scheduling and diagnostic timestamping. |
| CAN_TX, CAN_RX | FlexCAN differential bus interface | Direct connection to ISO 11898-2 transceiver; supports CAN-FD frames with bit-rate switching up to 5 Mbps. |
| ADC0_SE0–ADC0_SE31 | Analog input channels | 32 multiplexed inputs routed through TRGMUX; supports simultaneous sampling for motor phase current sensing. |
| NMI | Non-maskable interrupt input | Hardware-triggered emergency response path for fault detection (e.g., overtemperature, watchdog timeout). |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable architecture | System MPU, ECC on flash/SRAM, CRC module, and dual-watchdog (WDOG + EWM) enable compliance with ISO 26262 requirements for body control modules. |
| Low-power operation | Five power modes (RUN, STOP, VLPR, VLPS, LLS) with sub-μA stop-current; LPIT and LPTMR provide flexible wake-up sources for periodic sensor polling. |
| FlexIO peripheral | Configurable 8-pin module emulates UART, SPI, I2C, LIN, or PWM - eliminates need for external protocol translators in cost-sensitive designs. |
| EEPROM emulation | 4 KB FlexRAM supports wear-leveling and atomic write operations - replaces external EEPROM in calibration storage and fault log retention. |
| LPUART/LIN support | Three LPUART modules (two active on FS32K116) with LIN 2.2A/SAE J2602 compliance - enables direct communication with LIN slave nodes (e.g., door modules, sensors). |

FAQ
What is the maximum operating frequency of the FS32K116LFT0MLFR?
The FS32K116LFT0MLFR operates at a maximum frequency of 48 MHz using the Fast Internal RC oscillator (FIRC). Unlike higher-tier S32K1xx devices, it does not support HSRUN mode or SPLL-based clock multiplication, ensuring predictable timing behavior for safety-critical control loops. This fixed-frequency design simplifies EMC compliance and reduces clock tree complexity in cost-sensitive automotive modules.
Does the FS32K116LFT0MLFR support CAN-FD?
Yes, the FS32K116LFT0MLFR includes one FlexCAN module compliant with ISO 11898-1 that supports CAN-FD operation, enabling data rates up to 5 Mbps and payloads up to 64 bytes. Its CAN-FD capability is confirmed in the S32K1xx Data Sheet Rev. 15 feature comparison table and applies specifically to the K116 variant in 48-pin LQFP packaging.
What package type and pin count does FS32K116LFT0MLFR use?
FS32K116LFT0MLFR uses a 48-pin LQFP package (package code LF), with 43 GPIOs, 3 power supply pins (VDD/VDDA/VSS), and dedicated SWD debug interface pins. This package is pin-compatible with other S32K11x variants in the same footprint, enabling hardware reuse across performance tiers within the family.
Is CSEc (Cryptographic Services Engine) available on FS32K116LFT0MLFR?
Yes, FS32K116LFT0MLFR integrates the Cryptographic Services Engine (CSEc) supporting AES-128, SHA-256, and secure key storage. However, CSEc operations - including secure boot and key provisioning - must be executed in RUN mode (48 MHz), as HSRUN mode is not supported on this variant. This constraint is explicitly documented in the S32K1xx Data Sheet Rev. 15.
What is the flash memory size and ECC capability of FS32K116LFT0MLFR?
FS32K116LFT0MLFR contains 128 KB of program flash memory with full Error-Correcting Code (ECC) protection. ECC detects and corrects single-bit errors and detects double-bit errors in real time, ensuring firmware integrity in electrically noisy automotive environments - a requirement for ISO 26262 ASIL-B compliance.
