NXP Semiconductors FS32K118LAT0VLFT

Overview

FS32K118LAT0VLFT 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, 16 KB SRAM, and CSEc cryptographic security engine - deployed in electronic control units requiring ASIL-B compliance.

For engineers reviewing the FS32K118LAT0VLFT datasheet, FS32K118LAT0VLFT pinout, FS32K118LAT0VLFT application, or FS32K118LAT0VLFT equivalent, this page provides verified technical context, validated package mapping (48-pin LQFP), confirmed low-power peripheral set (LPUART/LPSPI/LPI2C), real-world timing constraints (HSRUN/RUN mode switching for EEPROM/CSEc), and two documented alternative parts for functional substitution in automotive ECU designs.

Technical Context

The FS32K118LAT0VLFT 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). Its memory subsystem includes 128 KB ECC-protected program flash, 16 KB SRAM with ECC, 4 KB FlexRAM for EEPROM emulation, and 2 KB data flash - all managed via a unified AXBS-Lite crossbar switch.

Power management is handled by the PMC supporting five modes: HSRUN (48 MHz), RUN, STOP, VLPR, and VLPS. Critical safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc engine - though CSEc execution and EEPROM operations require explicit transition from HSRUN to RUN mode (80 MHz not supported on this variant).

Key Specifications

Pinout & Package

FS32K118LAT0VLFT is packaged in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, with exposed thermal pad. Pin assignments follow the S32K11x family layout, supporting up to 43 GPIOs, dedicated SWD debug pins (SWD_CLK/SWD_IO), reset, clock inputs (SOSC/FIRC/SIRC), and analog reference (VREFH/VREFL).

FAQ

What is the maximum operating frequency of the FS32K118LAT0VLFT?

The FS32K118LAT0VLFT operates at a maximum frequency of 48 MHz in HSRUN mode. Unlike higher-tier S32K14x devices, it does not support 80 MHz or 112 MHz operation. This 48 MHz limit is fixed per its S32K118 designation and aligns with its Arm Cortex-M0+ core architecture and thermal envelope for V-grade (-40 °C to +105 °C) operation.

Does the FS32K118LAT0VLFT support CAN FD?

No, the FS32K118LAT0VLFT does not support CAN FD. It includes one FlexCAN module compliant with classical CAN 2.0B only. CAN FD capability is reserved for S32K14x-series parts (e.g., FS32K142MT0VLFT) and requires both hardware support and specific ordering option 'F' or 'A1' - which are absent in the FS32K118LAT0VLFT part number structure.

Can CSEc security functions be executed in HSRUN mode on the FS32K118LAT0VLFT?

No. CSEc (Cryptographic Services Engine) operations - including AES encryption, key derivation, and secure boot verification - cannot execute in HSRUN mode on the FS32K118LAT0VLFT. The device must transition to RUN mode (48 MHz) before initiating any CSEc command, as confirmed in the S32K1xx Data Sheet Rev. 15 section 1.1 and Figure 3 footnotes.

What package type and pin count does the FS32K118LAT0VLFT use?

The FS32K118LAT0VLFT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. This matches the S32K11x family's standard 48-pin LQFP option, providing up to 43 GPIOs, dedicated SWD debug pins, and full peripheral signal routing as defined in the S32K1xx Reference Manual IO Signal Description sheets.

Is the FS32K118LAT0VLFT qualified to AEC-Q100 standards?

Yes, the FS32K118LAT0VLFT is AEC-Q100 qualified for Grade 2 (-40 °C to +105 °C ambient), as indicated by its 'V' temperature grade suffix and documented in NXP's official S32K1xx qualification reports. This qualification covers stress testing for automotive environments including thermal cycling, humidity bias, and ESD robustness - essential for under-hood and cabin ECU deployment.
