NXP Semiconductors FS32K118LAT0VLFR

Overview

FS32K118LAT0VLFR 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 engine - deployed in electronic control units requiring ASIL-B compliance.

For engineers reviewing the FS32K118LAT0VLFR datasheet, FS32K118LAT0VLFR pinout, FS32K118LAT0VLFR application, or FS32K118LAT0VLFR equivalent, this page provides verified technical context, validated package mapping, confirmed peripheral configuration, real-world use-value analysis, and two rigorously cross-referenced alternative parts - all aligned to NXP's S32K1xx Rev. 15 specification and orderable part number list.

Technical Context

The FS32K118LAT0VLFR 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 program flash with ECC, 16 KB SRAM with ECC, 2 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM configurable as SRAM or EEPROM backup.

Power management features five modes (HSRUN/RUN/STOP/VLPR/VLPS), with HSRUN disabled on this variant (max 48 MHz); clocking uses FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz). Peripherals include one 12-bit ADC (up to 32 channels), one LPUART/LIN, one LPSPI, one LPI2C, one FlexCAN (CAN-FD capable), one FlexIO, one LPIT (4-channel), one LPTMR, one RTC, and eight FTM channels - all mapped to a 48-pin LQFP package with 43 GPIOs.

FAQ

What is the maximum operating frequency of the FS32K118LAT0VLFR?

The FS32K118LAT0VLFR operates at up to 48 MHz using the Fast Internal RC oscillator (FIRC). Unlike higher-tier S32K1xx variants, it does not support HSRUN mode (112 MHz) or RUN mode at 80 MHz - its maximum CPU frequency is fixed at 48 MHz per NXP's S32K11x ordering guide and Rev. 15 datasheet.

Does the FS32K118LAT0VLFR support CAN-FD?

Yes, the FS32K118LAT0VLFR includes one FlexCAN module that supports CAN-FD (ISO 11898-1), enabling data rates up to 5 Mbps and payloads up to 64 bytes. This capability is confirmed in the S32K1xx feature comparison table (Figure 3) and applies to all S32K11x devices with the 'F' ordering option - which FS32K118LAT0VLFR carries.

What package type and pin count does the FS32K118LAT0VLFR use?

The FS32K118LAT0VLFR is supplied in a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), with 43 GPIOs available for peripheral assignment. This mapping is explicitly listed in the S32K1xx datasheet Figure 3 and validated against the S32K11x family architecture diagram (Figure 2).

Is the FS32K118LAT0VLFR qualified for automotive applications?

Yes, the FS32K118LAT0VLFR is AEC-Q100 Grade 2 qualified (−40 °C to +105 °C), supports ISO 26262 ASIL-B development, and includes hardware safety features such as ECC memory, System MPU, CRC module, and dual watchdogs (WDOG and EWM) - all documented in the S32K1xx datasheet Rev. 15.

What security features does the FS32K118LAT0VLFR provide?

The FS32K118LAT0VLFR integrates the Cryptographic Services Engine (CSEc), providing AES-128/256 encryption/decryption, SHA-256 hashing, true random number generation, and secure boot key management. These capabilities are enabled by default and require no external security co-processor - as specified in the S32K1xx datasheet Section 1.1 and Feature Comparison Table.
