Product details
Overview
FS32K116LAT0VLFT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for real-time control in body electronics, lighting, and powertrain subsystems. 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 security engine.
For engineers reviewing the FS32K116LAT0VLFT datasheet, FS32K116LAT0VLFT pinout, FS32K116LAT0VLFT application, or FS32K116LAT0VLFT equivalent, this page delivers verified technical context, package-specific pin mapping, safety-critical timing features, and validated alternative options for ASIL-B–compliant automotive designs.
Technical Context
The FS32K116LAT0VLFT implements a single-core Arm Cortex-M0+ processor with Thumb®-2 ISA support, integrated Digital Signal Processing extensions, and a configurable NVIC - all optimized for deterministic low-latency response in automotive control loops. It includes dedicated hardware accelerators for CRC, cryptographic services (CSEc), and memory protection via NXP's system MPU at the crossbar switch level.
Its clock architecture combines FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) sources, enabling dynamic mode switching between RUN (48 MHz) and VLPR (low-power) states. Power management is governed by the PMC, supporting five distinct power modes with configurable peripheral clock gating and wake-up triggers from LPTMR, LPIT, or GPIO.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, Thumb-2 ISA, no FPU - optimized for deterministic real-time execution in resource-constrained automotive nodes. |
| Max Clock Frequency | 48 MHz in RUN mode - sufficient for LIN communication stacks, PWM-driven lighting control, and sensor fusion at <100 µs loop times. |
| Flash Memory | 128 KB program flash with ECC - enables safe over-the-air (OTA) updates and fault-tolerant code storage per ISO 26262 requirements. |
| SRAM | 16 KB on-chip SRAM with ECC - supports critical runtime variables and stack integrity in safety-critical functions. |
| Operating Voltage | 2.7 V to 5.5 V - compatible with 12 V automotive battery systems including cold-crank (down to 2.7 V) and load-dump transients. |
| Ambient Temperature | -40 °C to +105 °C (V-grade) - qualified for under-hood and cabin-mounted ECUs without derating. |
| Security Engine | Cryptographic Services Engine (CSEc) - provides AES-128, SHA-256, RNG, and secure boot key management for ECU authentication. |

Pinout & Package
FS32K116LAT0VLFT is packaged in a 48-pin LQFP (LF package code), with 43 GPIO pins, 4 dedicated power/ground pins, and function-multiplexed peripherals including LPUART, LPSPI, LPI2C, FlexCAN, and FlexTimer channels.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH, VREFL | Analog & digital supply rails | Separate analog/digital domains with tight coupling required; VDDA must be shorted to VDD on PCB for ADC accuracy. |
| RESET_b | Active-low reset input | Asynchronous reset signal with internal pull-up; initiates full device initialization and clears security state. |
| SWD_CLK, SWD_DIO | Serial Wire Debug interface | Two-pin debug port supporting programming, real-time trace, and non-intrusive breakpoints during vehicle diagnostics. |
| LPUART0_RX/TX | Low-power UART channel 0 | Supports LIN 2.2A protocol with automatic sync-break detection and sleep/wake framing for body control modules. |
| FLEXCAN0_TX/RX | CAN 2.0B transceiver interface | Direct connection to external CAN transceiver; supports error frame detection and bus-off recovery in chassis networks. |
| FTM0_CH0–CH7 | FlexTimer module outputs | Configurable as PWM, input capture, or quadrature decoder - used for LED dimming, motor commutation, or encoder feedback. |
Key Features
| Feature | Design Value |
|---|---|
| System MPU (Memory Protection Unit) | NXP's crossbar-level MPU enforces access rights per master (CPU/DMA), preventing unauthorized memory access - essential for ASIL-B partitioning. |
| CSEc Security Engine | Hardware-accelerated AES-128/SHA-256/RNG enables secure boot, firmware signing, and key provisioning without software overhead. |
| Low-Power Timer (LPTMR) | 16-bit timer with flexible clock source selection (LPO, SIRC, or external) - enables wake-from-VLPR events with sub-millisecond latency. |
| ECC on Flash & SRAM | Single-bit error correction and double-bit error detection across all memory blocks - meets ISO 26262 FIT rate targets for memory safety. |
| FlexIO Module | 8-pin programmable I/O block supporting UART, SPI, I2C, or PWM emulation - reduces BOM count when legacy protocols are needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LAT0VLFT | 256 KB flash, 32 KB SRAM, same core/package - adds memory headroom for future feature expansion. | Preferred where OTA update partitions, dual-bank flash, or larger RTOS footprint is required. | Select when additional memory is needed without changing PCB layout or toolchain. |
| MC9S12G128MALR | Legacy S12X core, 128 KB flash, no CSEc, no ECC, 25 MHz max - lacks modern safety/security features. | Suitable only for cost-sensitive legacy redesigns without functional safety requirements. | Choose only for brownfield projects requiring pin-compatible drop-in replacement with minimal firmware changes. |
Compared with FS32K116LAT0VLFT, FS32K118LAT0VLFT offers scalable memory while retaining identical safety architecture and pinout; MC9S12G128MALR provides legacy compatibility but requires external security and ECC implementation for ASIL-B compliance.

FAQ
What is the maximum operating frequency of the FS32K116LAT0VLFT?
The FS32K116LAT0VLFT operates at up to 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is reserved for M4F-based S32K14x devices. This 48 MHz frequency is fully validated across the -40 °C to +105 °C ambient range and supports deterministic execution of LIN, CAN, and PWM tasks in automotive body control applications. The FS32K116LAT0VLFT uses the Arm Cortex-M0+ core, not the M4F variant.
Does the FS32K116LAT0VLFT support CAN-FD?
No, the FS32K116LAT0VLFT does not support CAN-FD. It integrates a standard FlexCAN 2.0B controller compliant with ISO 11898-1, supporting data rates up to 1 Mbps. CAN-FD capability is available only in higher-tier S32K14x devices (e.g., FS32K144, FS32K146) and requires specific ordering options denoted by 'F' or 'A1' in the part number suffix. The FS32K116LAT0VLFT is intended for legacy CAN network nodes where FD bandwidth is unnecessary.
What package type is used for the FS32K116LAT0VLFT?
The FS32K116LAT0VLFT uses a 48-pin LQFP package (package code LF), measuring 7 mm × 7 mm with 0.5 mm pitch. This RoHS-compliant, lead-free package is optimized for automotive reflow profiles and supports full I/O accessibility for body control and lighting applications. Pin compatibility is maintained across all S32K11x devices in the same package variant, enabling scalable design reuse.
Is CSEc (Cryptographic Services Engine) available on the FS32K116LAT0VLFT?
Yes, the FS32K116LAT0VLFT includes the full Cryptographic Services Engine (CSEc) as specified in the S32K1xx Data Sheet Rev. 15. It supports AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure boot key management - all implemented in dedicated hardware to avoid software overhead and timing side-channel vulnerabilities. CSEc operation requires switching from VLPR to RUN mode, consistent with S32K1xx family behavior.
What is the flash memory size and ECC coverage for FS32K116LAT0VLFT?
The FS32K116LAT0VLFT contains 128 KB of program flash memory with full Error-Correcting Code (ECC) coverage for single-bit correction and double-bit detection. ECC is enabled by default at power-on and cannot be disabled - a mandatory feature for ISO 26262 ASIL-B compliance. Additionally, it includes 4 KB of FlexRAM usable as EEPROM emulation or SRAM, and 2 KB of FlexNVM for data flash, both also protected by ECC.
