NXP Semiconductors FS32K116LIT0VLFR

Overview

FS32K116LIT0VLFR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for body electronics, gateway, and powertrain control applications. 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 security engine.

For engineers reviewing the FS32K116LIT0VLFR datasheet, FS32K116LIT0VLFR pinout, FS32K116LIT0VLFR application, or FS32K116LIT0VLFR equivalent, this page provides verified technical context, package mapping, functional pin roles, safety-critical timing features, and validated alternative options for automotive ECU design.

Technical Context

The FS32K116LIT0VLFR implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode. It uses NXP's system-level MPU (not Arm Core MPU) for memory protection across AXBS-Lite crossbar masters including core and DMA, enforcing ASIL-B capable access rights per memory region.

Its power architecture supports five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), but HSRUN mode is disabled on this variant - only RUN (48 MHz), STOP, and VLPR/VLPS are active. Flash and SRAM include ECC; CSEc security operations require switching from RUN to VLPR mode for EEPROM emulation and secure boot functions.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the FS32K116LIT0VLFR?

The FS32K116LIT0VLFR operates at up to 48 MHz in RUN mode. Unlike higher-tier S32K14x devices, it does not support HSRUN mode (112 MHz); its clock tree is limited to FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz) sources. This frequency is fully supported across the -40 °C to +105 °C ambient range with 2.7–5.5 V supply.

Does the FS32K116LIT0VLFR support CAN FD?

No, the FS32K116LIT0VLFR does not support CAN FD. It integrates a single FlexCAN module compliant with ISO 11898-1 (Classical CAN 2.0B only). CAN FD capability is reserved for S32K14x series devices (e.g., FS32K144) and requires specific ordering option 'F' or 'A1' in the part number - absent in FS32K116LIT0VLFR's 'LIT0VLFR' suffix.

What package type and pin count does FS32K116LIT0VLFR use?

The FS32K116LIT0VLFR 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 footprint and supports up to 43 GPIOs, making it suitable for space-constrained automotive modules requiring moderate I/O density and thermal performance.

Is the FS32K116LIT0VLFR AEC-Q100 qualified?

Yes, the FS32K116LIT0VLFR is AEC-Q100 qualified for Grade 2 (-40 °C to +105 °C ambient), as confirmed by its 'V' temperature grade designation and inclusion in NXP's official S32K1xx automotive qualification documentation. It meets stress test requirements for HTOL, TC, UHAST, and ESD per AEC-Q100 Rev G.

Can FS32K116LIT0VLFR execute CSEc security functions in RUN mode?

Yes, FS32K116LIT0VLFR can execute CSEc cryptographic operations (AES, SHA, RNG) in RUN mode at 48 MHz. However, CSEc commands and EEPROM emulation writes/erases are explicitly prohibited in HSRUN mode - which this device does not support - so all security functions operate safely within its native RUN mode envelope without requiring mode switching.
