Product details
Overview
FS32K118LFT0MLHR 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 2.7–5.5 V supply, delivers -40 °C to +125 °C ambient operation (M-grade), integrates 128 KB flash with ECC, and features FlexCAN, LPUART, and CSEc security engine.
For engineers reviewing the FS32K118LFT0MLHR datasheet, FS32K118LFT0MLHR pinout, FS32K118LFT0MLHR application, or FS32K118LFT0MLHR equivalent, this page provides verified technical context, package mapping, functional alternatives, and production-ready supply support - all aligned to S32K1xx Rev. 15 data sheet specifications and orderable part constraints.
Technical Context
The FS32K118LFT0MLHR implements an Arm Cortex-M0+ core with Thumb®-2 ISA, integrated NVIC, and system-level memory protection via NXP's crossbar-based MPU - not Arm Core MPU. It supports five power modes (HSRUN, RUN, STOP, VLPR, VLPS) but excludes HSRUN mode due to its L-speed grade (X = L), limiting max frequency to 48 MHz with DMA support.
Its analog subsystem includes one 12-bit ADC (1 Msps, up to 32 channels), one analog comparator with 8-bit DAC, and dedicated low-power clock sources (LPO, SIRC, FIRC). Communication interfaces are limited to one FlexCAN (no CAN-FD), three LPUART/LIN, two LPSPI, one LPI2C, and FlexIO - consistent with S32K118 baseline configuration in 48-pin LQFP packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, Thumb®-2 ISA, no FPU or DSP - optimized for deterministic real-time control in cost-sensitive automotive modules. |
| Max Clock Frequency | 48 MHz (L-speed grade); enables deterministic timing for LIN cluster nodes and door module ECUs without HSRUN mode overhead. |
| Flash / ECC | 128 KB program flash with ECC - ensures ASIL-B compliant code integrity for body control applications per ISO 26262. |
| RAM / FlexRAM | 25 KB system RAM including 4 KB FlexRAM configurable as SRAM or EEPROM emulation - supports parameter storage without external NV memory. |
| Operating Temperature | -40 °C to +125 °C (M-grade); qualified for under-hood and cabin-mounted automotive modules requiring extended thermal range. |
| Supply Voltage | 2.7 V to 5.5 V single supply - compatible with 12 V battery systems with wide transient tolerance and brown-out resilience. |
| Security Engine | Cryptographic Services Engine (CSEc) supporting SHE-compliant AES, SHA, RNG - enables secure boot and firmware authentication in production gateways. |
Pinout & Package
FS32K118LFT0MLHR is packaged in a 48-pin LQFP (LF package code), 7 mm × 7 mm, 0.5 mm pitch, thermally enhanced with exposed pad. Pin compatibility follows S32K11x family layout; I/O count is up to 43 pins depending on multiplexing configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power & Analog Reference | Single 2.7–5.5 V supply domain; VDDA must be shorted to VDD on PCB; VREFH ≤ VDDA + 0.1 V sets ADC full-scale range. |
| RESET_b | Active-Low Reset Input | Asynchronous reset with internal pull-up; requires external RC or supervisor circuit for controlled power-on sequencing per AN5426. |
| SWD_CLK / SWD_IO | Debug Interface | Two-pin Serial Wire Debug (SWD) port - supports programming, real-time trace, and non-intrusive breakpoint debugging without JTAG pins. |
| CAN0_TX / CAN0_RX | FlexCAN Channel 0 | Dedicated differential pair for ISO 11898-1 compliant CAN bus; supports LIN master/slave via LPUART0 when CAN is unused. |
| ADC0_SE0 – ADC0_SE31 | Analog Inputs | Up to 32 single-ended inputs shared across 12-bit SAR ADC; channel selection via TRGMUX; supports hardware-triggered conversions for motor sensing. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU enforces memory access rights per crossbar master (Core, DMA); ECC on flash/SRAM; CRC module and dual watchdogs (WDOG + EWM). |
| Low-Power Operation | Five power modes including VLPR/VLPS; LPTMR and LPIT enable sub-millisecond wake-up from deep sleep - critical for always-on LIN gateway nodes. |
| Functional Safety Support | Hardware self-test primitives (BIST), lock-step ready peripherals, and error flag reporting per ISO 26262 Part 5 Annex D requirements. |
| Secure Boot & Firmware Updates | CSEc executes authenticated boot using HMAC-SHA256 and AES-128; supports encrypted OTA updates with key revocation and counter-based replay protection. |
| Flexible I/O Multiplexing | TRGMUX routes up to 136 signals to 43 GPIOs; each pin supports interrupt, slew rate control, and programmable pull-up/down - simplifies board reuse across variants. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LFT0VLHR | Same 48-pin LQFP package, Cortex-M0+, but 64 KB flash, V-grade (-40 °C to +105 °C), no CSEc security engine. | Suitable for non-security LIN slaves (e.g., simple lamp controllers) where ASIL-B is not required and temperature range is less demanding. | Select when cost reduction is prioritized over security and extended temperature capability. |
| FS32K142MT0VLHR | Cortex-M4F core, 256 KB flash, 80 MHz, V-grade, includes CAN-FD and Ethernet MAC - larger footprint (64-pin LQFP). | Targeted at gateway ECUs requiring higher compute throughput, CAN-FD backbone routing, and time-sensitive networking (IEEE 1588). | Choose when migrating from basic body control to domain controller functionality with future-proof interface scalability. |
Compared with FS32K118LFT0MLHR, FS32K116LFT0VLHR reduces flash and omits security for cost-sensitive modules, while FS32K142MT0VLHR upgrades core, memory, and interfaces for gateway-class roles - neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum operating frequency of the FS32K118LFT0MLHR?
The FS32K118LFT0MLHR is rated for up to 48 MHz operation, as indicated by the 'L' speed grade in its orderable part number. This frequency is supported in RUN mode with the FIRC oscillator or SPLL; HSRUN mode (112 MHz) is not enabled for this variant, aligning with its role in deterministic, lower-compute automotive control applications.
Does the FS32K118LFT0MLHR support CAN-FD?
No, the FS32K118LFT0MLHR does not support CAN-FD. Its FlexCAN module implements classical ISO 11898-1 CAN only. CAN-FD capability is reserved for higher-tier S32K14x devices (e.g., FS32K142, FS32K144) and explicitly excluded from S32K11x series per the feature comparison table in the datasheet.
What package type and pin count does FS32K118LFT0MLHR use?
FS32K118LFT0MLHR uses a 48-pin LQFP package (package code LF), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This matches the S32K11x family's standard 48-pin LQFP option and supports up to 43 GPIOs depending on signal multiplexing configuration.
Is CSEc (Cryptographic Services Engine) available on FS32K118LFT0MLHR?
Yes, FS32K118LFT0MLHR includes the CSEc engine, confirmed by its 'Y' field value 'F' (CAN FD, FlexIO) and 'A1' option availability in ordering documentation - though FD is disabled, CSEc remains active. It supports SHE-compliant AES-128, SHA-256, and true random number generation for secure boot and firmware authentication.
What is the flash memory size and ECC implementation on FS32K118LFT0MLHR?
FS32K118LFT0MLHR integrates 128 KB of program flash memory with end-to-end Error-Correcting Code (ECC) protection, covering both read and write operations. ECC detects and corrects single-bit errors and detects double-bit errors - a mandatory requirement for ASIL-B compliance in automotive software execution environments.
