Product details
Overview
FS32K118LFT0MLFR 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 +125 °C ambient temperature, integrates 128 KB flash with ECC, 25 KB SRAM, and features CSEc security engine, FlexCAN (1 channel), and LPUART/LIN interfaces.
For engineers reviewing the FS32K118LFT0MLFR datasheet, FS32K118LFT0MLFR pinout, FS32K118LFT0MLFR application, or FS32K118LFT0MLFR equivalent, this page delivers verified technical context, package mapping, real-world use scenarios, and validated alternative options aligned to ISO 26262 ASIL-B requirements.
Technical Context
The FS32K118LFT0MLFR implements an Arm Cortex-M0+ core without FPU or DSP extensions, operating at up to 48 MHz in RUN mode - distinct from M4F-based S32K14x variants. Its memory subsystem includes 128 KB program flash with ECC, 25 KB SRAM (including FlexRAM), and 2 KB FlexNVM for EEPROM emulation.
Power management supports HSRUN, RUN, STOP, VLPR, and VLPS modes; however, HSRUN mode is not available on this M0+ variant - only RUN (48 MHz), STOP, and low-power modes are implemented. CSEc security operations and EEPROM writes require switching from RUN to VLPR mode per functional constraints documented in the S32K1xx datasheet.
Key Specifications

Pinout & Package
FS32K118LFT0MLFR is packaged in a 48-pin LQFP (LF package code), with 43 GPIO pins, dedicated reset, clock inputs (SOSC, FIRC, SIRC, LPO), and peripheral-specific signal groups including CAN_TX/RX, UART, SPI, I²C, ADC inputs, and debug SWD pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled individually; VDDA/VREFH tolerance ±0.1 V vs VDD ensures ADC accuracy within 1 LSB error band |
| PTA0–PTA7, PTB0–PTB15, PTC0–PTC15 | GPIO with interrupt capability | Configurable as input/output/pull-up/pull-down; supports edge-triggered interrupts for wake-from-STOP event detection |
| CAN0_TX / CAN0_RX | FlexCAN differential interface | Requires external CAN transceiver; supports ISO 11898-1 physical layer with bus fault recovery via internal loopback test mode |
| LPUART0_RX / LPUART0_TX | Low-power UART interface | Operates in VLPR mode at 4 MHz system clock - enables LIN slave node communication with <10 µA sleep current |
| SWD_CLK / SWD_DIO | Serial Wire Debug port | Enables non-intrusive debugging and flash programming without JTAG pins; supports trace via ITM and DWT units |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | Integrated System MPU, ECC on flash/SRAM, CRC module, and WDOG/EWM - satisfies hardware-level safety mechanisms per ISO 26262 Part 5 |

| Secure Boot & Key Management | CSEc enforces authenticated firmware loading using HMAC-SHA256 and encrypted AES-128 keys stored in protected memory regions |
| Flexible Clocking | Four independent oscillators (FIRC, SIRC, LPO, SOSC) enable seamless clock source switching during runtime - critical for fail-safe clock monitoring |
| EEPROM Emulation | 2 KB FlexNVM + 4 KB FlexRAM provide wear-levelled non-volatile storage for calibration data without external EEPROM chip |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LFT0MLFR | 64 KB flash, 16 KB SRAM, same 48-pin LQFP package and M-grade temp range | Suitable for simpler LIN nodes with reduced firmware complexity and smaller data buffers | Select when application fits within 64 KB flash and does not require FlexNVM-based EEPROM emulation |
| FS32K142HT0MLFR | Arm Cortex-M4F core, 80 MHz, 256 KB flash, 64 KB SRAM, 2x FlexCAN, Ethernet MAC | Targeted at higher-performance gateway or domain controller roles requiring CAN FD and time-sensitive networking | Choose when migrating from K118 to M4F architecture for enhanced compute, safety partitioning, or future CAN FD readiness |

FAQ
What is the maximum operating frequency of FS32K118LFT0MLFR?
The FS32K118LFT0MLFR operates at up to 48 MHz in RUN mode. Unlike M4F-based S32K14x devices, it does not support HSRUN mode or frequencies above 48 MHz. This speed is fully supported across its -40 °C to +125 °C operating range and aligns with LIN and basic CAN timing budgets.
Does FS32K118LFT0MLFR support CAN FD?
No, FS32K118LFT0MLFR does not support CAN FD. It includes one FlexCAN module compliant with ISO 11898-1 Classical CAN (up to 1 Mbps). CAN FD capability is reserved for S32K14x devices with 'F' or 'A1' ordering option Y codes - FS32K118LFT0MLFR is limited to standard CAN and LIN protocols.
What package type is used for FS32K118LFT0MLFR?
FS32K118LFT0MLFR uses a 48-pin LQFP package (package code LF), measuring 7 mm × 7 mm with 0.5 mm pitch. This RoHS-compliant package supports reflow soldering and is pin-compatible with other 48-pin S32K11x variants like FS32K116LFT0MLFR.
Can FS32K118LFT0MLFR execute CSEc security functions in RUN mode?
Yes, FS32K118LFT0MLFR can execute CSEc cryptographic operations in RUN mode at 48 MHz. However, CSEc commands - including AES encryption, SHA hashing, and secure boot verification - must not be issued concurrently with Flash or FlexNVM write/erase operations, which require temporary mode switching to VLPR per NXP's functional constraints.
Is FS32K118LFT0MLFR qualified for automotive applications?
Yes, FS32K118LFT0MLFR is AEC-Q100 Grade 1 qualified (-40 °C to +125 °C), ISO 26262 ASIL-B ready, and designed for automotive body electronics. Its integrated System MPU, ECC memory protection, WDOG/EWM, and CSEc meet functional safety requirements for production ECUs in passenger vehicles.
