Product details
Overview
FS32K118LAT0MLHT 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, 16 KB SRAM, and features CSEc cryptographic engine, FlexCAN (1x), LPUART (3x), and 48-pin LQFP package.
For engineers reviewing the FS32K118LAT0MLHT datasheet, FS32K118LAT0MLHT pinout, FS32K118LAT0MLHT application, or FS32K118LAT0MLHT equivalent, this page delivers verified technical context, validated pin mapping, real-world use cases in automotive subsystems, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The FS32K118LAT0MLHT implements a single-core Arm Cortex-M0+ CPU without FPU, 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, 16 KB SRAM, and 2 KB FlexNVM for EEPROM emulation, all constrained by mandatory mode switching (to RUN) during CSEc or EEPROM operations.
Peripherals are scaled for entry-level automotive applications: one FlexCAN module (no CAN-FD), three LPUART/LIN interfaces, two LPSPI, one LPI2C, one 12-bit ADC (up to 16 channels), eight FlexTimer channels, and system-level safety features including System MPU, CRC, WDOG, and EWM - all qualified per ISO 26262 ASIL-B requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, max 48 MHz - optimized for deterministic low-power control tasks, not DSP-intensive workloads. |
| Flash / SRAM | 128 KB program flash with ECC + 16 KB SRAM - sufficient for AUTOSAR-compliant BSW stacks with error resilience. |
| Operating Temp | -40 °C to +125 °C (M-grade) - supports under-hood placement in engine control modules and junction boxes. |
| Supply Voltage | 2.7 V to 5.5 V - compatible with 12 V automotive battery systems including cold-crank (down to 2.7 V). |
| FlexCAN | 1 × CAN 2.0B controller - enables communication with ECUs like lighting controllers or HVAC modules, no CAN-FD support. |
| ADC | 1 × 12-bit SAR ADC, up to 16 input channels - suitable for sensor monitoring (e.g., temperature, pressure, potentiometer feedback). |
| Security | Cryptographic Services Engine (CSEc) - provides AES-128, SHA-256, RNG, and secure boot key management, requires RUN mode (80 MHz not available on this part) for execution. |
| Package | 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) - standard footprint for cost-sensitive automotive PCBs with manual rework capability. |
Pinout & Package
FS32K118LAT0MLHT is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant and moisture-sensitive level 3. Pin functions align with the S32K11x family's I/O multiplexing scheme, supporting up to 43 GPIOs with interrupt capability, dedicated JTAG/SWD debug pins, and configurable peripheral signals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be shorted on PCB with local decoupling; VREFH ≤ VDDA + 0.1 V ensures ADC accuracy across temp/voltage range. |
| PTA0–PTA31, PTB0–PTB10 | GPIO / peripheral multiplexed I/O | 43 total usable GPIOs; each supports interrupt, pull-up/down, and slew-rate control - critical for switch sensing and LED driving. |
| TSWCLK, TSWDIO | SWD debug interface | 2-pin serial wire debug port - enables full JTAG/SWD access for production programming and field diagnostics. |
| CAN0_TX, CAN0_RX | FlexCAN differential bus interface | Direct connection to external CAN transceiver (e.g., TJA1042); no internal termination - requires external 120 Ω resistor. |
| ADC0_SE0–ADC0_SE15 | Analog input channels | 16 dedicated ADC inputs mapped to GPIO pins - supports simultaneous sampling of multiple sensors with hardware trigger support. |
| RESET_b | Active-low reset input | Asynchronous, Schmitt-triggered input - compatible with external watchdog ICs (e.g., NCV8853) for fail-safe reset coordination. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | Integrated System MPU, CRC, WDOG, EWM, and ECC on flash/SRAM - satisfies decomposition requirements for ASIL-B subsystems without external safety monitors. |
| Low-Power Operation | Five power modes (RUN, STOP, VLPR, VLPS, HSRUN) with sub-μA stop-current - enables always-on wake-up via LPUART or GPIO for body control modules. |
| Secure Boot & Cryptography | CSEc engine supports AES-128 encryption, SHA-256 hashing, and secure key storage - enables firmware authentication and OTA update integrity verification. |
| Automotive Communication Suite | 3 × LPUART (LIN-capable), 2 × LPSPI, 1 × LPI2C - supports multi-protocol sensor networks (e.g., LIN door modules + SPI pressure sensors + I2C ambient light). |
| Robust Analog Interface | 12-bit ADC with hardware averaging, calibration support, and flexible trigger sources - delivers ±1 LSB INL over -40 °C to +125 °C for precision sensor conditioning. |
| Flexible Timer System | 8-channel FlexTimer + LPIT + LPTMR - enables PWM generation for motor control, pulse counting for wheel speed, and low-power periodic wake-up events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LAT0MLHT | Same core, package, and temp grade; reduced memory (64 KB flash, 8 KB SRAM) and fewer peripherals (2 LPUART, 1 LPSPI, no FlexIO). | Suitable for simpler LIN gateways or basic lighting controllers where memory headroom and peripheral count are non-critical. | Select when BOM cost reduction is prioritized over future firmware scalability or peripheral flexibility. |
| MC9S12XEQ512MALR | Legacy S12XE 16-bit core, 512 KB flash, 32 KB RAM, CAN 2.0B only, no CSEc, -40 °C to +125 °C rating. | Used in legacy automotive platforms requiring long-term continuity; lacks modern safety features (ECC, MPU) and low-power modes. | Choose only for drop-in replacement in existing S12XE designs; not recommended for new development due to obsolescence and safety limitations. |
Compared with FS32K118LAT0MLHT, FS32K116LAT0MLHT offers lower cost but constrains firmware growth and peripheral expansion, while MC9S12XEQ512MALR provides pin-compatible legacy support but lacks ISO 26262-ready safety mechanisms and cryptographic security - making FS32K118LAT0MLHT the optimal balance of modern safety, security, and scalability for new automotive designs.

FAQ
What is the maximum operating frequency of the FS32K118LAT0MLHT?
The FS32K118LAT0MLHT operates at a maximum frequency of 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is exclusive to M4F-based S32K14x devices. This 48 MHz clock is generated from the 48 MHz FIRC oscillator or optionally from the SOSC with PLL multiplication - all fully specified in the S32K1xx Reference Manual.
Does the FS32K118LAT0MLHT support CAN-FD?
No, the FS32K118LAT0MLHT includes only one FlexCAN module compliant with CAN 2.0B protocol and does not support CAN-FD. CAN-FD capability is reserved for higher-tier S32K14x devices (e.g., FS32K142, FS32K144) with enhanced CAN controllers and larger memory footprints.
What package type and pin count does the FS32K118LAT0MLHT use?
The FS32K118LAT0MLHT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as confirmed by NXP's official ordering information and package drawings in the S32K1xx Datasheet Rev. 15. This package supports 43 GPIOs and is pin-compatible with other 48-pin S32K11x variants like FS32K116LAT0MLHT.
Can the FS32K118LAT0MLHT execute CSEc cryptographic operations in HSRUN mode?
No - CSEc (Cryptographic Services Engine) operations, along with EEPROM writes/erases, are explicitly prohibited in HSRUN mode because the FS32K118LAT0MLHT does not support HSRUN mode at all. All CSEc execution must occur in RUN mode, which for this part is capped at 48 MHz, consistent with its M0+ core specification.
What is the flash memory size and ECC support on the FS32K118LAT0MLHT?
The FS32K118LAT0MLHT integrates 128 KB of program flash memory with full Error-Correcting Code (ECC) protection, as documented in the S32K1xx Data Sheet Section 1.1 and Memory chapter. ECC detects and corrects single-bit errors and detects double-bit errors - essential for ASIL-B compliance in automotive applications.
