Product details
Overview
FS32K116LAT0VFMT 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, 25 KB SRAM, and CSEc cryptographic engine - deployed in electronic control units requiring ASIL-B compliance.
For engineers reviewing the FS32K116LAT0VFMT datasheet, FS32K116LAT0VFMT pinout, FS32K116LAT0VFMT application, or FS32K116LAT0VFMT equivalent, key selection criteria include its V-grade thermal rating, 48-pin LQFP package, M0+ core architecture, FlexCAN/LPUART/LPSPI peripheral set, and mandatory RUN-mode execution for CSEc/EEPROM operations - all critical for automotive ECU design validation and functional safety qualification.
Technical Context
The FS32K116LAT0VFMT implements an Arm Cortex-M0+ core without FPU, operating at up to 48 MHz in RUN mode (not HSRUN), with dedicated low-power modes (VLPR/VLPS/STOP) and a Power Management Controller (PMC). Its memory subsystem includes 128 KB program flash with ECC, 25 KB system RAM (including FlexRAM), and 2 KB FlexNVM for EEPROM emulation - all subject to strict mode-dependent access restrictions.
Peripheral integration centers on automotive I/O requirements: one FlexCAN module (CAN-FD capable), three LPUART/LIN interfaces, two LPSPI modules, one LPI2C, 43 GPIOs with interrupt capability, one 12-bit ADC (1 Msps, up to 16 channels), and safety peripherals including CRC, WDOG, EWM, System MPU, and CSEc - all mapped to the 48-pin LQFP footprint with defined signal multiplexing per the S32K1xx Reference Manual.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, no FPU, 48 MHz max - optimized for deterministic real-time control in cost-sensitive automotive nodes. |
| Flash Memory | 128 KB with ECC - enables robust code storage and error detection for ASIL-B applications without external redundancy. |
| SRAM | 25 KB total (including FlexRAM) - supports real-time task stacks, CAN message buffers, and safety-critical data structures. |
| Operating Voltage | 2.7 V to 5.5 V - compatible with 12 V automotive battery systems including cold-crank (2.7 V) and load-dump (5.5 V) transients. |
| Temperature Range | -40 °C to 105 °C ambient (V-grade) - qualified for under-hood and cabin ECU placement per AEC-Q100 Grade 2. |
| FlexCAN | 1 module with CAN-FD support - enables high-speed diagnostics, firmware updates, and domain controller communication at up to 5 Mbps. |
| Security Engine | CSEc with SHE-compliant crypto - provides secure boot, key management, and AES-128/SHA-256 acceleration, but requires RUN mode (not HSRUN) for execution. |
| ADC | 12-bit SAR, 1 Msps, up to 16 channels - suitable for sensor monitoring (temperature, pressure, position) with integrated oversampling for noise reduction. |
Pinout & Package
FS32K116LAT0VFMT is housed in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch) package with exposed thermal pad. Pin assignments follow the S32K11x family mapping, supporting full signal multiplexing via TRGMUX and IO PORT controllers as documented in the S32K1xx Reference Manual.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be shorted on PCB with local decoupling; VDDA/VREFH define ADC accuracy and must stay within ±0.1 V of VDD. |
| RESET_B | Active-low reset input | Asynchronous reset source; internal pull-up ensures safe startup; compatible with external watchdog or power monitor assertion. |
| SWD_CLK / SWD_DIO | Serial Wire Debug interface | Two-pin debug port supporting programming, real-time trace, and safety verification - no JTAG pins required. |
| CAN0_TX / CAN0_RX | FlexCAN differential bus interface | Direct connection to external CAN transceiver; supports ISO 11898-1 physical layer and CAN-FD protocol framing. |
| LPUART0_RX / LPUART0_TX | Low-power UART channel | Enables LIN 2.x diagnostics and bootloader communication with <1 µA sleep current and automatic wake-on-break detection. |
| ADC0_SE0–ADC0_SE15 | Analog input channels | 16 single-ended inputs routed through dedicated analog mux; supports hardware-triggered conversions synchronized to PWM or timer events. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | Integrated System MPU, ECC on flash/SRAM, CRC engine, dual watchdog (WDOG + EWM), and lockstep-capable peripherals enable ISO 26262 compliance without external safety monitors. |
| Automotive Low-Power Operation | VLPR mode draws <100 µA at 4 MHz; VLPS mode achieves <2.5 µA with RTC running - extends battery life in always-on gateway and sensor nodes. |
| Secure Boot & Firmware Updates | CSEc executes SHA-256 signature verification and AES-128 decryption in RUN mode, enabling authenticated over-the-air (OTA) updates with tamper-resistant key storage. |
| Flexible Clock Management | FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) sources feed configurable clock gates - allows dynamic switching between performance and ultra-low-power states. |
| Robust I/O Protection | All GPIOs support 5 V tolerant inputs, ±3 mA DC injection, and transient immunity up to 6.8 V - meets automotive EMC requirements without external clamping diodes. |
| EEPROM Emulation | 2 KB FlexNVM with wear-leveling and atomic write/erase - replaces external serial EEPROM in body control modules while maintaining data retention >10 years at 105 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LAT0VFMT | Same package and core, but with 256 KB flash, 32 KB SRAM, and 2x ADC modules - no change in CPU speed or temperature grade. | Supports larger firmware images and dual-sensor domains (e.g., HVAC + lighting), but increases BOM cost without added performance. | Select FS32K118LAT0VFMT only when code size exceeds 128 KB or dual ADC concurrency is required; otherwise FS32K116LAT0VFMT offers optimal cost/performance balance. |
| MC9S12XEP100MALR | Legacy S12X 16-bit MCU with 1 MB flash, no CSEc, no CAN-FD, and limited low-power modes - requires external EEPROM and lacks modern safety features. | Suitable for legacy platform refresh where toolchain migration is constrained, but cannot meet new ASIL-B or OTA update requirements. | Choose MC9S12XEP100MALR only for brownfield designs with fixed toolchains; FS32K116LAT0VFMT provides superior safety, security, and power efficiency for new platforms. |
Compared with FS32K118LAT0VFMT, the FS32K116LAT0VFMT reduces flash/SRAM capacity while retaining identical safety architecture, CAN-FD, and thermal rating - making it ideal for cost-optimized ECU designs. Against MC9S12XEP100MALR, it delivers modern Arm-based toolchain support, integrated security, and lower active power - essential for next-generation automotive electronics.

FAQ
What is the maximum operating frequency of the FS32K116LAT0VFMT?
The FS32K116LAT0VFMT operates at up to 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is exclusive to M4F-core variants like the S32K14x series. 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 FS32K116LAT0VFMT support CAN-FD?
Yes, the FS32K116LAT0VFMT includes one FlexCAN module with CAN-FD capability per the S32K1xx Data Sheet Feature Comparison table. It supports ISO 11898-1 physical layer and CAN-FD protocol framing up to 5 Mbps, enabling high-bandwidth diagnostics and firmware updates in modern automotive networks.
Can CSEc cryptographic operations run in HSRUN mode on the FS32K116LAT0VFMT?
No - the FS32K116LAT0VFMT does not support HSRUN mode at all, as it uses an Arm Cortex-M0+ core (not M4F). CSEc operations execute in RUN mode, consistent with the device's architecture. The datasheet note about HSRUN restriction applies only to M4F-based S32K14x devices.
What package type and pin count does the FS32K116LAT0VFMT use?
The FS32K116LAT0VFMT uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad, as specified in the S32K1xx Data Sheet Package section and confirmed in the ordering information diagram. This matches the "LF" package code in its part number suffix.
Is the FS32K116LAT0VFMT qualified to AEC-Q100 standards?
Yes, the FS32K116LAT0VFMT is AEC-Q100 qualified for Grade 2 (-40 °C to +105 °C), as indicated by its "V" temperature grade designation and explicit listing in NXP's automotive qualification documentation. This qualification covers reliability testing for automotive under-hood and cabin environments.
