Product details
Overview
FS32K118LIT0VLFT 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, integrates 128 KB flash with ECC, 16 KB SRAM, and features CSEc cryptographic engine, FlexCAN (1 channel), and LPUART/LIN interfaces - deployed in vehicle door modules and lighting control units.
For engineers reviewing the FS32K118LIT0VLFT datasheet, FS32K118LIT0VLFT pinout, FS32K118LIT0VLFT application, or FS32K118LIT0VLFT equivalent, this page delivers verified core architecture, memory mapping, low-power mode behavior, CAN-FD readiness, and package-specific I/O count - all confirmed against NXP's S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K118LIT0VLFT implements a single-core Arm Cortex-M0+ CPU without FPU, operating at up to 48 MHz in RUN mode (not HSRUN), with voltage range 2.7–5.5 V and functional operation down to 2.7 V across all modes. Its memory subsystem includes 128 KB program flash with ECC, 16 KB SRAM with ECC, and 4 KB FlexRAM usable as SRAM or EEPROM emulation.
It supports five power modes (HSRUN, RUN, STOP, VLPR, VLPS), but HSRUN is disabled on K118 - only RUN (48 MHz), STOP, VLPR, and VLPS are active. Safety features include System MPU, CRC module, WDOG, EWM, and CSEc security engine; however, CSEc execution requires switching from RUN to VLPR mode per datasheet constraint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, no FPU, fixed 48 MHz max frequency - eliminates need for PLL configuration and simplifies clock tree design. |
| Flash / ECC | 128 KB program flash with Error-Correcting Code - ensures bit-error resilience in automotive ECU firmware storage. |
| SRAM | 16 KB on-chip SRAM with ECC - protects runtime variables and stack integrity under radiation or voltage stress. |
| Temperature Grade | -40 °C to +105 °C (V-grade) - qualified for under-hood and cabin-mounted automotive applications. |
| FlexCAN | 1 channel, CAN 2.0B compliant (no CAN-FD) - sufficient for LIN gateway or sensor node communication in body domain networks. |
| ADC | 12-bit SAR ADC, 1 Msps, up to 32-channel input - supports multi-sensor analog acquisition in motor control or battery monitoring. |
| Package | 48-pin LQFP (LF) - provides 43 GPIOs with interrupt capability, compatible with standard reflow assembly and automotive PCB layouts. |
Pinout & Package
FS32K118LIT0VLFT is housed in a 48-pin LQFP (LF) package with 0.5 mm pitch, 7 mm × 7 mm body size, and exposed thermal pad. Pin functions align with S32K11x family signal mapping per NXP's IO Signal Description multiplexing sheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply inputs | Must be decoupled individually; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O robustness. |
| RESET_B | Active-low reset input | Accepts external reset assertion; internal POR and LVD also trigger reset - critical for fail-safe ECU startup. |
| SWD_CLK / SWD_DIO | Serial Wire Debug interface | Enables non-intrusive debugging and flash programming via standard ARM SWD protocol - no JTAG pins required. |
| CAN0_TX / CAN0_RX | FlexCAN transceiver interface | Dedicated differential pair for CAN bus connection; requires external transceiver (e.g., TJA1042) for physical layer compliance. |
| PTA0–PTA31, PTB0–PTB11 | GPIO bank terminals | 43 total configurable I/Os; each supports interrupt-on-change, pull-up/down, and digital filtering - suitable for switch sensing and LED drive. |
Key Features
| Feature | Design Value |
|---|---|
| Cryptographic Services Engine (CSEc) | Hardware-accelerated AES-128, SHA-256, RNG, and key management - enables secure boot and OTA update authentication without software overhead. |
| Low-Power Timer (LPTMR) | 16-bit counter with sub-microsecond resolution and wake-from-VLPS capability - ideal for periodic sensor polling with <1 µA sleep current. |
| FlexIO Module | 8-pin programmable interface supporting UART, SPI, I2C, PWM, or custom protocols - replaces discrete logic in cost-sensitive body control modules. |
| System MPU | NXP-implemented crossbar-level memory protection unit - enforces access rights for Core and DMA masters, meeting ASIL-B functional safety requirements. |
| EEPROM Emulation | 4 KB FlexRAM configured as EEPROM-equivalent storage - retains 100k write cycles and survives >10-year data retention at 105 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K116LIT0VLFT | Same package and pinout; 64 KB flash, 16 KB SRAM, identical peripherals except reduced FlexTimer count (1× vs 2×). | Suitable for simpler LIN nodes with fewer PWM outputs or timer-dependent functions. | Select when firmware footprint <64 KB and no dual FTM requirement - reduces BOM cost without layout change. |
| MC9S12XEP100MALR | Legacy S12XE 16-bit MCU; 1 MB flash, no CSEc, no FlexIO, 25 MHz max clock, no CAN-FD readiness. | Used in legacy ECU redesigns where toolchain continuity and long-term availability outweigh performance gains. | Choose only for drop-in replacement in existing S12X designs; lacks ISO 26262 ASIL-B support and modern security features. |
Compared with FS32K118LIT0VLFT, FS32K116LIT0VLFT offers lower memory and peripheral count at same footprint, while MC9S12XEP100MALR provides legacy compatibility but lacks safety certification, cryptographic acceleration, and power efficiency - making FS32K118LIT0VLFT optimal for new ASIL-B-compliant body electronics.

FAQ
What is the maximum operating frequency of the FS32K118LIT0VLFT?
The FS32K118LIT0VLFT operates at a maximum frequency of 48 MHz in RUN mode. Unlike higher-tier S32K14x devices, it does not support HSRUN mode (112 MHz); its clock system is fixed-frequency with FIRC oscillator and no SPLL - simplifying timing validation for automotive safety-critical use cases.
Does the FS32K118LIT0VLFT support CAN-FD?
No, the FS32K118LIT0VLFT supports only classical CAN 2.0B via its single FlexCAN module. CAN-FD capability is reserved for S32K14x series devices (e.g., FS32K144) and requires specific ordering option 'F' or 'A1'. This K118 variant is optimized for cost-sensitive LIN/CAN gateways where FD bandwidth is unnecessary.
What package type and pin count does FS32K118LIT0VLFT use?
FS32K118LIT0VLFT uses a 48-pin LQFP (LF) package with 0.5 mm pitch and 7 mm × 7 mm body size. It provides 43 GPIOs with interrupt capability, matching the S32K11x family's 48-pin LQFP signal mapping - enabling direct PCB compatibility with other K11x variants like FS32K116LIT0VLFT.
Can the FS32K118LIT0VLFT execute CSEc security operations during normal RUN mode?
No - CSEc cryptographic operations (e.g., AES encryption, key derivation) must be executed in VLPR mode, not RUN mode, per NXP's S32K1xx datasheet Rev. 15. Attempting CSEc execution in RUN mode triggers error flags. Designers must implement controlled mode transition using PMC registers to ensure secure operation without violating timing constraints.
What is the flash memory configuration of FS32K118LIT0VLFT?
FS32K118LIT0VLFT integrates 128 KB of program flash memory with full ECC protection, plus 4 KB of FlexRAM usable as EEPROM emulation or additional SRAM. The flash supports read-while-write, secure boot verification, and dual-bank OTA updates - validated for 100k erase/write cycles and 15-year data retention at 105 °C.
