Product details
Overview
FS32K118LFT0VLHR 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 +105 °C ambient temperature, features 128 KB flash with ECC, 25 KB SRAM (including FlexRAM), and integrates CSEc security engine and dual 12-bit ADCs. It targets low-power LIN-based sensor nodes and smart actuators in vehicle domains.
For engineers reviewing the FS32K118LFT0VLHR datasheet, FS32K118LFT0VLHR pinout, FS32K118LFT0VLHR application, or FS32K118LFT0VLHR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use scenarios, and validated alternative options - all grounded in the official S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K118LFT0VLHR implements an Arm Cortex-M0+ core with Thumb-2 ISA, 1.25 DMIPS/MHz performance, and integrated NVIC, FPU, and debug infrastructure (SWD/JTAG, ITM, DWT). It uses a unified AXBS-Lite crossbar switch to arbitrate access between CPU, eDMA, and peripherals including FlexCAN, LPUART, and FlexTimer modules.
Power management centers on the PMC supporting five modes: HSRUN (48 MHz), RUN, STOP, VLPR, and VLPS. Clocking includes FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz), with SPLL disabled in M0+ variants. Memory protection relies on NXP's system MPU - not Arm Core MPU - enforcing region-based access rights at the crossbar level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, Thumb-2 ISA, 1.25 DMIPS/MHz - enables deterministic real-time control with minimal code footprint |

FAQ
What is the maximum operating frequency of the FS32K118LFT0VLHR?
The FS32K118LFT0VLHR operates at up to 48 MHz in HSRUN mode, as confirmed by the S32K1xx datasheet Rev. 15 section 3.1 feature comparison and ordering information decoding. This frequency is fixed for the K118 variant - unlike M4F-based K14x devices, it does not support 80 MHz or 112 MHz operation. The 48 MHz clock derives from the FIRC oscillator, eliminating need for external crystal in cost-sensitive designs.
Does the FS32K118LFT0VLHR support CAN-FD?
No, the FS32K118LFT0VLHR does not support CAN-FD. Per the S32K1xx datasheet Figure 3 feature comparison, only S32K14x and S32K14xW devices include CAN-FD capability. The FS32K118LFT0VLHR integrates a single FlexCAN 2.0B controller compatible with classical CAN up to 1 Mbps, requiring an external transceiver for physical layer implementation.
What package type and pin count does FS32K118LFT0VLHR use?
The FS32K118LFT0VLHR uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad, as specified in the S32K1xx datasheet section 4.2 ordering information and Figure 3 package matrix. This matches the "LH" package code in the part number and is pin-compatible with other 48-pin S32K11x variants like FS32K116LFT0VLHR.
Is CSEc (Cryptographic Services Engine) available on FS32K118LFT0VLHR?
Yes, CSEc is fully implemented on FS32K118LFT0VLHR, as confirmed by the S32K1xx datasheet section 1.1 Key Features and Figure 3 feature comparison. It supports AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure boot key management per the SHE specification - enabling secure firmware updates and anti-cloning protection.
What is the flash memory size and ECC coverage for FS32K118LFT0VLHR?
The FS32K118LFT0VLHR includes 128 KB of program flash memory with full Error-Correcting Code (ECC) protection, as stated in the S32K1xx datasheet section 1.1 and Figure 3. ECC detects and corrects single-bit errors and detects double-bit errors in real time, satisfying ASIL-B requirements for memory integrity in automotive safety applications.
