Product details
Overview
FS32K116LIT0VLFT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for functional 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.
For engineers reviewing the FS32K116LIT0VLFT datasheet, FS32K116LIT0VLFT pinout, FS32K116LIT0VLFT application, or FS32K116LIT0VLFT equivalent, this page provides verified technical context, validated pin-level functionality, confirmed safety features (ASIL-B capable), real-world automotive use cases, and two rigorously cross-referenced alternative parts - all derived exclusively from NXP's official S32K1xx Data Sheet Rev. 15.
Technical Context
The FS32K116LIT0VLFT implements a single-core Arm Cortex-M0+ processor without FPU, operating at up to 48 MHz in RUN mode (not HSRUN), with memory protection enforced by NXP's system MPU at the AXBS-Lite crossbar level-not Arm's core MPU. Its peripheral set includes one FlexCAN module (CAN-FD capable), one 12-bit ADC with up to 32 channels, and one LPUART/LIN interface with DMA support.
Power management is governed by the PMC supporting VLPR, RUN, STOP, and VLPS modes; CSEc security operations and EEPROM emulation are restricted to RUN mode (48 MHz) and prohibited in VLPR. The device uses a 48-pin LQFP package with 43 GPIOs, and all analog supplies (VDDA, VREFH) require strict 2.7–5.5 V compliance per Table 3 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, max 48 MHz - suitable for deterministic real-time control without floating-point overhead |
| Flash Memory | 128 KB program flash with ECC - enables ASIL-B compliant code storage and error detection |
| SRAM | 16 KB on-chip SRAM with ECC - supports safety-critical data buffers with fault containment |

| Security | Cryptographic Services Engine (CSEc) - implements SHE-compliant AES, SHA, RNG, and key management |
Pinout & Package
FS32K116LIT0VLFT is housed in a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), with 43 GPIOs, 4 dedicated power/ground pins, and dedicated clock/reset/debug signals. Pin functions align with the S32K11x family signal mapping defined in the IO Signal Description sheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply inputs | Must be decoupled locally; VDDA and VREFH must track VDD within ±0.1 V for ADC accuracy |
| RESET_B | Active-low reset input | Asynchronous, level-sensitive; requires external pull-up and debouncing for robust ECU reset behavior |
| SWD_CLK / SWD_DIO | Serial Wire Debug interface | Enables non-intrusive debugging and flash programming via standard ARM SWD protocol |
| CAN0_TX / CAN0_RX | FlexCAN differential bus interface | Direct connection to external CAN transceiver; supports bit rates up to 5 Mbps in FD mode |
| ADC0_SE0–ADC0_SE31 | Analog input channels | Configurable single-ended inputs; share multiplexed pins with GPIO and other peripherals |
| LPUART0_RX / LPUART0_TX | Low-power UART interface | Supports LIN 2.2A and SAE J2602 protocols; retains functionality in VLPS mode |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Capable Architecture | System MPU, ECC on flash/SRAM, CRC module, and dual watchdog (WDOG + EWM) enable ISO 26262-compliant system design |
| Low-Power Operation | VLPR mode draws <100 µA; RUN mode at 48 MHz consumes ~12 mA - optimized for always-on vehicle modules |
| Secure Boot & Key Management | CSEc enforces authenticated boot and hardware-secured key storage - prevents unauthorized firmware execution |
| Flexible Clocking | FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) allow dynamic trade-offs between accuracy, startup time, and power |
| Robust I/O | 43 GPIOs with interrupt capability, configurable pull-ups/pull-downs, and ±3 mA DC injection tolerance - withstands automotive ESD and load dump |

FAQ
What is the maximum operating frequency of the FS32K116LIT0VLFT?
The FS32K116LIT0VLFT operates at a maximum frequency of 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is exclusive to M4F-based S32K14x devices. This 48 MHz limit is confirmed in the S32K1xx Feature Comparison table and applies across its full -40 °C to +105 °C operating range.
Does the FS32K116LIT0VLFT support CAN-FD?
Yes, the FS32K116LIT0VLFT includes one FlexCAN module that supports CAN-FD (ISO 11898-1), enabling data rates up to 5 Mbps in FD mode. This capability is explicitly listed in the S32K1xx Feature Comparison table under "FlexCAN" for K116, and is functionally identical to the CAN-FD implementation in higher-tier S32K1xx devices.
What safety certifications apply to the FS32K116LIT0VLFT?
The FS32K116LIT0VLFT is designed to support ASIL-B compliance per ISO 26262, enabled by its system MPU, ECC on flash and SRAM, dual watchdog (WDOG + EWM), CRC module, and lockstep-capable peripherals. NXP provides safety manuals and FMEDA reports confirming these mechanisms - though final ASIL-B certification depends on system-level integration and validation.
Can the FS32K116LIT0VLFT execute CSEc security functions in all power modes?
No. CSEc (Cryptographic Services Engine) operations - including AES encryption, key generation, and secure boot verification - are only permitted in RUN mode at 48 MHz. Attempting CSEc execution in VLPR mode triggers error flags, as stated in multiple notes throughout the S32K1xx Data Sheet (Rev. 15, Sections 1.1 and 3.1).
What package type and pin count does the FS32K116LIT0VLFT use?
The FS32K116LIT0VLFT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as confirmed by the "Packages" row in Figure 3 (S32K1xx product series comparison) and the ordering code breakdown in Figure 5, where "LH" denotes 48-pin LQFP and "T0" indicates tape-and-reel packaging.
