Product details
Overview
FS32K118LAT0MLHR 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 FlexCAN, LPUART, and CSEc security engine.
For engineers reviewing the FS32K118LAT0MLHR datasheet, FS32K118LAT0MLHR pinout, FS32K118LAT0MLHR application, or FS32K118LAT0MLHR equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options aligned with ISO 26262 ASIL-B requirements.
Technical Context
The FS32K118LAT0MLHR implements a single-core Arm Cortex-M0+ processor without FPU, optimized for deterministic real-time control in automotive ECUs. It supports HSRUN mode at 48 MHz (not 112 MHz - reserved for M4F variants), uses SIRC/FIRC oscillators and SPLL for clock generation, and enforces memory protection via NXP's system MPU at the crossbar switch level.
Power management includes five modes (HSRUN, RUN, STOP, VLPR, VLPS), but HSRUN is disabled for CSEc or EEPROM operations - those require switching to RUN mode. Analog subsystem comprises one 12-bit ADC (1 Msps, up to 32 channels) and one comparator with integrated 8-bit DAC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, Thumb-2 ISA - deterministic real-time execution with low interrupt latency |
| Max Clock Frequency | 48 MHz in HSRUN mode - sufficient for LIN gateway, sensor fusion, and basic CAN messaging |
| Flash Memory | 128 KB program flash with ECC - enables robust code storage and error detection in harsh environments |
| SRAM | 25 KB system RAM including FlexRAM - configurable as SRAM or EEPROM emulation for nonvolatile data logging |
| 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 +125 °C (M-grade) - qualified for under-hood and transmission control applications |
| Security | Cryptographic Services Engine (CSEc) - hardware-accelerated AES, SHA, RNG, and secure boot key management |
| ADC | 12-bit SAR ADC, 1 Msps, up to 32 inputs - supports high-resolution analog sensing for throttle position, temperature, and pressure |
Pinout & Package
FS32K118LAT0MLHR is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per the S32K11x IO Signal Description multiplexing sheet and support full GPIO remapping via PORT module.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled individually; VDDA and VREFH require low-noise filtering for ADC accuracy |
| PTA0–PTA31, PTB0–PTB15, PTC0–PTC15 | GPIO bank terminals | Up to 43 configurable I/Os with interrupt capability; most support analog input, PWM output, or peripheral function multiplexing |
| CAN0_TX / CAN0_RX | FlexCAN interface signals | Dedicated differential pair for ISO 11898-1 CAN bus communication; supports LIN via LPUART in break-detect mode |
| LPUART0_RX / LPUART0_TX | Low-power UART interface | Enables wake-up from VLPS mode on start-bit detection - critical for always-on vehicle networks |
| FTM0_CH0–FTM0_CH7 | FlexTimer channel outputs | Configurable as PWM, input capture, or quadrature decoder - used for motor control and encoder interfacing |
| ADC0_SE0–ADC0_SE31 | Analog input channels | Single-ended inputs mapped to dedicated pins; internal mux allows scanning up to 32 signals per conversion sequence |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B capable architecture | System MPU, ECC on flash/SRAM, CRC module, and dual-watchdog (WDOG + EWM) meet functional safety requirements for body control modules |
| Low-power operation | VLPS mode draws <2.5 µA - enables long-term battery monitoring without compromising ECU responsiveness |
| Secure boot & key provisioning | CSEc supports authenticated firmware loading and protected key storage - prevents unauthorized firmware updates in production vehicles |
| Flexible clocking | FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) enable precise trade-offs between performance, accuracy, and power |
| Peripheral interoperability | TRGMUX and DMAMUX allow autonomous peripheral chaining (e.g., ADC → DMA → LPIT → GPIO toggle) without CPU intervention |
Applications
| Body Control Module (BCM) | Door Module Controller |
|---|---|
Use Scenario: Centralized management of lighting, window lift, mirror adjustment, and door lock actuation in modern passenger vehicles.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LAT0MLHR | 64 KB flash, 16 KB SRAM, same core/package/temperature grade - lacks second ADC module and one FlexCAN channel | Suitable for simpler LIN-only nodes without redundant sensing or CAN redundancy | Select when BOM cost reduction is prioritized and feature headroom is not required |
| FS32K142MT0VLHR | Arm Cortex-M4F core, 256 KB flash, 512 KB total memory, 80 MHz max frequency, 100-pin LQFP package | Supports Ethernet, dual CAN-FD, and audio interfaces - intended for gateway or domain controller roles | Choose when migrating to higher-performance compute, safety-certified software stacks, or multi-protocol bridging |
Compared with FS32K118LAT0MLHR, FS32K116LAT0MLHR reduces memory and peripheral count for cost-sensitive entry-level nodes, while FS32K142MT0VLHR expands compute, memory, and interface bandwidth for centralized control - both require PCB redesign due to different pin counts and package footprints.

FAQ
What is the maximum operating frequency of the FS32K118LAT0MLHR?
The FS32K118LAT0MLHR operates at up to 48 MHz in HSRUN mode. Unlike M4F variants in the S32K14x series, this M0+ device does not support 112 MHz operation. Its clock tree uses FIRC (48 MHz), SIRC (8 MHz), and SOSC (4–40 MHz) sources, with SPLL enabling precise frequency synthesis for peripheral timing. This frequency is fully validated across the -40 °C to +125 °C temperature range.
Does the FS32K118LAT0MLHR support CAN FD?
No, the FS32K118LAT0MLHR does not support CAN FD. It integrates a single FlexCAN module compliant with ISO 11898-1 (Classical CAN only). CAN FD capability is available only in S32K14x-series devices (e.g., FS32K142, FS32K144) and requires specific ordering options denoted by 'F' or 'A1' in the part number suffix. The FS32K118LAT0MLHR remains fully compatible with legacy CAN 2.0B networks used in body electronics.
What package type and pin count does the FS32K118LAT0MLHR use?
The FS32K118LAT0MLHR uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible with other S32K11x devices in the same footprint, including FS32K116LAT0MLHR. Pin assignments follow the S32K11x IO Signal Description multiplexing sheet, supporting up to 43 GPIOs, 32 ADC inputs, and dedicated CAN/LPUART/LPSPI interfaces.
Is the FS32K118LAT0MLHR qualified for automotive safety standards?
Yes, the FS32K118LAT0MLHR is designed to support ASIL-B compliance per ISO 26262. It includes hardware safety mechanisms such as ECC on flash and SRAM, System MPU for memory access control, dual watchdogs (WDOG and EWM), CRC acceleration, and lockstep-capable peripherals. While the MCU itself is not certified, its architecture and documentation enable integration into ASIL-B systems when used with appropriate safety software and development processes.
Can the FS32K118LAT0MLHR execute CSEc security operations in HSRUN mode?
No, the FS32K118LAT0MLHR cannot execute CSEc (Cryptographic Services Engine) operations or EEPROM writes/erases in HSRUN mode. Attempting these functions triggers error flags. The device must switch to RUN mode (48 MHz) to perform secure boot verification, AES encryption, or FlexNVM programming. This restriction is explicitly documented in the S32K1xx Data Sheet Rev. 15 and applies uniformly across all S32K11x devices.
