Product details
Overview
FS32K118LFT0VLFT 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 105 °C ambient temperature (V-grade), delivers up to 48 MHz CPU frequency, and integrates 128 KB flash with ECC, 25 KB SRAM, and CSEc cryptographic engine.
For engineers reviewing the FS32K118LFT0VLFT datasheet, FS32K118LFT0VLFT pinout, FS32K118LFT0VLFT application, or FS32K118LFT0VLFT equivalent, key selection considerations include its V-grade thermal rating, 48-pin LQFP package, LIN-capable LPUART peripherals, FlexTimer-based PWM generation for motor control, and mandatory RUN-mode execution for CSEc security operations.
Technical Context
The FS32K118LFT0VLFT implements an Arm Cortex-M0+ core without FPU, targeting deterministic real-time control in ASIL-B systems. It uses a single 48 MHz FIRC oscillator as primary clock source and supports HSRUN mode only at lower frequencies (not applicable per S32K11x spec), with full peripheral availability in RUN mode.
Its memory subsystem includes 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, and 25 KB total SRAM (including FlexRAM). Safety features include System MPU, CRC module, WDOG, EWM, and CSEc - though CSEc execution requires switching from HSRUN to RUN mode (80 MHz not supported on K118).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, optimized for deterministic low-latency control loops |

FAQ
What is the maximum operating frequency of the FS32K118LFT0VLFT?
The FS32K118LFT0VLFT operates at a maximum frequency of 48 MHz using the Fast Internal RC (FIRC) oscillator. Unlike higher-tier S32K14x devices, it does not support HSRUN mode or PLL-based 80/112 MHz operation - all timing-critical functions are validated at 48 MHz in RUN mode.
Does the FS32K118LFT0VLFT support CAN FD?
No, the FS32K118LFT0VLFT does not support CAN FD. It integrates a single FlexCAN 2.0B controller compatible with classical CAN protocols only. CAN FD capability is reserved for S32K14x series devices such as FS32K142MT0VLFT and above.
What package type is used for the FS32K118LFT0VLFT?
The FS32K118LFT0VLFT uses a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible with other S32K11x variants in the same pin count, enabling design reuse across memory and feature variants.
Can the FS32K118LFT0VLFT execute CSEc security functions in HSRUN mode?
No, the FS32K118LFT0VLFT cannot execute CSEc security functions in HSRUN mode because it does not support HSRUN mode at all. CSEc operations must run in RUN mode - consistent with S32K11x family constraints where security and EEPROM writes are prohibited during high-frequency operation.
How much SRAM is available on the FS32K118LFT0VLFT?
The FS32K118LFT0VLFT provides 25 KB of total on-chip SRAM, including FlexRAM configured as system RAM. This allocation supports real-time task stacks, LIN/CAN message buffers, and safety monitor variables while meeting ASIL-B memory partitioning requirements.
