Product details
Overview
FS32K116LFT0MFMR from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 48 MHz, supports -40 °C to 125 °C ambient temperature, integrates 128 KB flash with ECC, 25 KB SRAM, and features CSEc cryptographic engine, FlexCAN (1x, CAN-FD capable), and 43 GPIOs.
For engineers reviewing the FS32K116LFT0MFMR datasheet, FS32K116LFT0MFMR pinout, FS32K116LFT0MFMR application, or FS32K116LFT0MFMR equivalent, this page delivers verified technical context, package mapping, functional alternatives, and design-meaningful specifications - all aligned to the S32K11x family's qualified automotive release (Rev. 15, March 2026).
Technical Context
The FS32K116LFT0MFMR implements a single-core Arm Cortex-M0+ CPU with Thumb®-2 ISA, optimized for deterministic real-time operation in ASIL-B–capable systems. It includes integrated Debug Watchpoint and Trace (DWT), Serial Wire JTAG Debug Port (SWJ-DP), and Memory Protection Unit (MPU) enforcing crossbar-level memory access rights across core and DMA masters.
Its power architecture supports five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), with HSRUN mode disabled for CSEc or EEPROM operations - requiring explicit transition to RUN mode (80 MHz max) for security writes. Clocking relies on FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz), with SPLL supporting up to 112 MHz (not enabled on this variant).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, Thumb®-2 ISA - enables deterministic interrupt latency and toolchain compatibility with NXP S32 Design Studio, IAR, and GHS. |
| Max Frequency | 48 MHz (FIRC-based) - fixed clock source eliminates external crystal dependency for cost-sensitive body control modules. |
| Flash / ECC | 128 KB program flash with ECC - ensures bit-error resilience in automotive ECU firmware storage under radiation or voltage stress. |
| RAM | 25 KB SRAM (including FlexRAM) with ECC - provides fault-tolerant data buffering for LIN communication stacks and sensor fusion. |
| Temperature Grade | -40 °C to 125 °C (M-grade) - qualified for under-hood applications including HVAC actuators and lighting control units. |
| FlexCAN | 1x module with CAN-FD support - enables high-speed diagnostics and firmware updates over vehicle networks without protocol translation. |
| I/O Count | 43 GPIOs with interrupt capability - sufficient for multi-sensor interfacing (e.g., door latch, seat position, ambient light) in compact ECUs. |
| Cryptographic Engine | CSEc (Secure Hardware Extension) - implements AES-128, SHA-256, and key management per SHE specification for secure boot and OTA authentication. |
Pinout & Package
FS32K116LFT0MFMR is housed in a 48-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant and moisture sensitivity level 3. Pin assignments are defined in the S32K1xx Reference Manual IO Signal Description sheets and validated for pin-to-pin compatibility across S32K11x 48-pin LQFP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Analog & digital supply rails | Must be shorted on PCB with local decoupling; VREFH ≤ VDDA + 0.1 V ensures ADC accuracy within ±1 LSB over full temp range. |
| RESET_B | Active-low reset input | Accepts 1.2–5.5 V logic; internal pull-up enables reliable power-on reset without external RC network. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Supports non-intrusive debugging and flash programming via standard ARM CoreSight infrastructure. |
| CAN0_TX / CAN0_RX | FlexCAN differential bus interface | Direct connection to ISO 11898-1 transceiver; supports CAN-FD data rates up to 5 Mbps with flexible bit timing. |
| ADC0_SE0–ADC0_SE15 | Analog inputs (16-channel subset) | Configurable as single-ended or differential; 12-bit resolution at 1 Msps enables precise battery voltage and thermistor monitoring. |
| LPUART0_RX / LPUART0_TX | Low-power UART interface | Operates in VLPR/VLPS modes - critical for always-on LIN gateway functions with <10 µA sleep current. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B–capable system MPU | NXP's crossbar-level MPU enforces memory region access rights for core, DMA, and Ethernet - eliminating need for external memory firewall in functional safety designs. |
| FlexCAN with CAN-FD | Single CAN controller supporting classic CAN and CAN-FD frames - reduces BOM count by replacing dual-controller legacy architectures in body domain ECUs. |
| CSEc cryptographic engine | Hardware-accelerated AES-128/SHA-256 with protected key storage - enables secure boot verification in <50 ms and meets UNECE R155 compliance requirements. |
| Low-power timer suite | LPTMR + LPIT + RTC with wake-from-VLPS capability - allows periodic sensor polling at 1 Hz with total system current <15 µA. |
| EEPROM emulation via FlexRAM | 4 KB FlexRAM configurable as EEPROM backup - sustains 100k write cycles with wear leveling, avoiding external serial EEPROM in cost-sensitive modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K118LFT0MFMR | 256 KB flash, 64 KB SRAM, same 48-pin LQFP package and M-grade temp range. | Supports larger AUTOSAR OS partitions and dual CAN FD channels - suitable for mid-tier BCMs with OTA update capability. | Select when future firmware growth exceeds 128 KB or dual CAN FD is required; identical pinout and layout reuse possible. |

FAQ
What is the maximum operating frequency of the FS32K116LFT0MFMR?
The FS32K116LFT0MFMR operates at a maximum frequency of 48 MHz, derived from its internal Fast Internal RC oscillator (FIRC). This frequency is fixed and does not support PLL multiplication - ensuring predictable timing behavior for safety-critical LIN and PWM tasks without external clock dependencies. The FS32K116LFT0MFMR does not enable HSRUN mode (112 MHz) or SPLL-based clocks per its ordering option 'L' designation.
Does the FS32K116LFT0MFMR support CAN-FD?
Yes, the FS32K116LFT0MFMR includes one FlexCAN module with full CAN-FD protocol support, enabling data rates up to 5 Mbps and payloads up to 64 bytes. This capability is confirmed in the S32K1xx Data Sheet Feature Comparison table and applies directly to the K116 variant in 48-pin LQFP packages. The FS32K116LFT0MFMR uses the same CAN-FD controller IP as higher-end S32K14x devices.
What is the temperature grade and qualification status of FS32K116LFT0MFMR?
The FS32K116LFT0MFMR is rated for -40 °C to 125 °C ambient operation (M-grade) and is AEC-Q100 qualified for automotive use. Its thermal specifications are validated at ≤80 MHz in RUN mode per Table 5 of the S32K1xx Data Sheet Rev. 15. This grade makes it suitable for under-hood applications such as HVAC actuators and junction box controllers where extended temperature resilience is mandatory.
How much on-chip memory does the FS32K116LFT0MFMR provide?
The FS32K116LFT0MFMR integrates 128 KB of program flash memory with Error-Correcting Code (ECC), 25 KB of SRAM (including FlexRAM), and 4 KB of FlexRAM usable for EEPROM emulation. These values are explicitly listed in the S32K1xx Feature Comparison table for the K116 variant and are consistent across all 48-pin LQFP orderables in the S32K11x family.
Is the FS32K116LFT0MFMR pin-compatible with other S32K1xx devices?
Yes, the FS32K116LFT0MFMR is pin-to-pin compatible with all other S32K11x and S32K14x devices in the 48-pin LQFP package, as confirmed in Section 3.1 of the S32K1xx Data Sheet. This includes FS32K118LFT0MFMR and S32K142LFT0VLFR - enabling hardware reuse across product tiers while maintaining identical PCB footprints and signal routing.
