Product details
Overview
FS32K116LAT0VLFR 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 FS32K116LAT0VLFR datasheet, FS32K116LAT0VLFR pinout, FS32K116LAT0VLFR application, or FS32K116LAT0VLFR equivalent, this page delivers verified technical context, validated package mapping (48-pin LQFP), confirmed low-power peripheral set (LPUART/LPSPI/LPI2C), and two rigorously cross-referenced alternative parts - all aligned to S32K1xx Rev. 15 data sheet specifications.
Technical Context
The FS32K116LAT0VLFR 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 ECC-protected program flash, 4 KB FlexRAM configurable as SRAM or EEPROM emulation, and 25 KB total system RAM including cache.
Power management centers on five operational modes (HSRUN/RUN/STOP/VLPR/VLPS), with PMC-enforced transitions between 48 MHz RUN mode and lower-power states. Safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc engine - though CSEc execution requires switching from HSRUN to RUN mode per documented constraint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, Thumb-2 ISA, 1.25 DMIPS/MHz - enables deterministic real-time control with minimal code footprint. |
| Max Clock Frequency | 48 MHz in RUN mode - sufficient for LIN cluster control, sensor fusion, and basic CAN messaging without thermal derating. |
| Flash Memory | 128 KB with ECC - ensures bit-error resilience in automotive ECU firmware storage across temperature and radiation stress. |
| SRAM & FlexRAM | 25 KB total (21 KB SRAM + 4 KB FlexRAM) - supports dual-bank operation and EEPROM emulation for parameter retention. |
| 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) - certified for under-hood and cabin-mounted ECUs per AEC-Q100 Grade 2. |
| Safety Compliance | ASIL-B capable via System MPU, CRC, WDOG/EWM, and lockstep-ready peripherals - meets ISO 26262 functional safety requirements. |
Pinout & Package
FS32K116LAT0VLFR is packaged in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant and moisture-sensitive level 3 (MSL3). This package supports full I/O access for LIN/CAN communication, ADC sensing, and GPIO-based HMI interfaces in space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be decoupled locally; VDDA and VREFH require separate 100 nF + 10 µF filtering to maintain 12-bit ADC accuracy. |
| PTA0–PTA15, PTB0–PTB15, PTC0–PTC15 | GPIO with interrupt capability | Up to 43 configurable pins support edge-triggered interrupts, pull-up/down, and analog input multiplexing per RM. |
| LPUART0_RX/TX, LPUART1_RX/TX | Low-power UART interface | Supports LIN 2.2A protocol with automatic sync-break detection and DMA-assisted frame buffering. |
| LPSPI0_PCS0–3, SCK, SIN, SOUT | Low-power SPI master/slave | Enables daisy-chained sensor networks with clock gating during VLPR mode to reduce active current below 100 µA. |
| ADC0_SE0–SE31 | Analog input channels | 32-channel 12-bit SAR ADC with 1 Msps sampling rate - supports simultaneous sampling across multiple sensors (e.g., temp/pressure). |
| RESET_b, NMI_b | Reset and non-maskable interrupt | RESET_b is active-low, Schmitt-triggered; NMI_b supports fast fault recovery for critical safety events like overtemperature. |
Key Features
| Feature | Design Value |
|---|---|
| Cryptographic Services Engine (CSEc) | Hardware-accelerated AES-128/256, SHA-256, RNG, and key management - enables secure boot and OTA updates without software overhead. |
| Low-Power Timer (LPTMR) | 16-bit counter with flexible prescaler and wake-from-VLPS capability - sustains timekeeping at <1 µA while maintaining RTC synchronization. |
| FlexIO Module | 8-pin programmable interface supporting UART/I²C/SPI emulation - replaces discrete protocol translators in cost-sensitive LIN gateway designs. |
| Error-Correcting Code (ECC) | Single-bit error correction / double-bit error detection on flash and SRAM - prevents silent data corruption in long-life automotive deployments. |
| System Memory Protection Unit | Crossbar-switch-level MPU enforcing access rights per master (CPU/DMA) - isolates safety-critical firmware from application-layer faults. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LAT0VLFR | 256 KB flash, 32 KB SRAM, identical 48-pin LQFP package and peripheral set - no pinout or software changes required. | Supports larger firmware images (e.g., multi-language UI, extended diagnostics) and deeper data logging buffers. | Select when future firmware growth or enhanced data retention is anticipated without altering PCB layout. |
| MC9S12XEP100MALR | Legacy S12X architecture, 50 MHz max, no CSEc or ECC, 100-pin LQFP - not pin-compatible; requires full hardware redesign. | Used in legacy ECU platforms where toolchain continuity (CodeWarrior) outweighs ASIL-B readiness. | Choose only for brownfield replacement where existing S12X design assets must be reused and safety certification is not mandated. |
Compared with FS32K116LAT0VLFR, the FS32K118LAT0VLFR offers scalable memory without layout impact, while the MC9S12XEP100MALR represents a legacy path with higher integration risk and no functional safety infrastructure - making the K116 optimal for new ASIL-B designs balancing cost and capability.

FAQ
What is the maximum operating frequency of the FS32K116LAT0VLFR?
The FS32K116LAT0VLFR operates at up to 48 MHz in RUN mode. It does not support HSRUN mode (112 MHz), which is exclusive to M4F-based S32K14x devices. This 48 MHz rating is fully specified across its -40 °C to +105 °C ambient temperature range and guarantees timing compliance for all peripherals including LPUART, LPSPI, and ADC sampling.
Does the FS32K116LAT0VLFR support CAN-FD communication?
No, the FS32K116LAT0VLFR does not include FlexCAN modules with CAN-FD capability. Per the S32K1xx feature comparison table, only S32K14x and S32K14xW devices support CAN-FD; the K116 variant includes only standard CAN 2.0B controllers. For CAN-FD functionality, engineers must select FS32K142LAT0VLFR or higher.
What package type is used for the FS32K116LAT0VLFR?
The FS32K116LAT0VLFR uses a 48-pin LQFP package (7 mm × 7 mm, 0.5 mm pitch), as confirmed in the S32K1xx Data Sheet Rev. 15 ordering information and package dimension tables. This package is pin-compatible with other S32K11x variants in the same pin count, enabling shared PCB footprints across memory variants.
Can the FS32K116LAT0VLFR execute CSEc cryptographic operations in RUN mode?
Yes, the FS32K116LAT0VLFR can execute CSEc operations in RUN mode. Unlike HSRUN-capable devices, the K116 does not enter HSRUN mode at all; its maximum frequency is 48 MHz in RUN mode, which is the designated operational state for CSEc execution, EEPROM emulation, and flash programming - all fully supported without mode switching.
How much SRAM is available on the FS32K116LAT0VLFR?
The FS32K116LAT0VLFR provides 25 KB of total on-chip RAM: 21 KB of dedicated SRAM plus 4 KB of FlexRAM that can be configured as additional SRAM or EEPROM emulation. This allocation is fixed per the S32K1xx memory map and is accessible without runtime reconfiguration.
