Product details
Overview
FS32K116LIT0MFMR 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 security engine, 12-bit ADC, and FlexCAN interface.
For engineers reviewing the FS32K116LIT0MFMR datasheet, FS32K116LIT0MFMR pinout, FS32K116LIT0MFMR application, or FS32K116LIT0MFMR equivalent, this page delivers verified technical context, package mapping, functional alternatives, and supply-chain support specific to the FS32K116LIT0MFMR - not the broader S32K1xx family.
Technical Context
The FS32K116LIT0MFMR implements a single-core Arm Cortex-M0+ CPU without FPU, operating at up to 48 MHz in RUN mode (not HSRUN), with memory protection enforced via NXP's system MPU at the crossbar switch level. It supports five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), but HSRUN is disabled on this variant per ordering code 'L' (48 MHz with DMA).
Its analog subsystem includes one 12-bit SAR ADC (1 Msps) with up to 32 channels, one analog comparator with integrated 8-bit DAC, and dedicated low-power timers (LPTMR, LPIT). Communication is handled by one FlexCAN module (CAN-FD capable), two LPUART/LIN interfaces, two LPSPI modules, and one LPI2C module - all with DMA support and low-power operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, no FPU - optimized for deterministic real-time control with minimal interrupt latency. |
| Clock Speed | Up to 48 MHz (RUN mode only) - fixed frequency ceiling; HSRUN mode (112 MHz) is not enabled on this part. |
| Flash Memory | 128 KB program flash with ECC - ensures data integrity for ASIL-B compliant firmware storage. |
| SRAM | 25 KB total SRAM (including FlexRAM) - supports real-time task stacks and buffer management in safety-critical contexts. |
| Temperature Range | -40 °C to +125 °C (M-grade) - qualified for under-hood automotive applications requiring extended thermal resilience. |
| Security | Cryptographic Services Engine (CSEc) - enables AES-128, SHA-256, RNG, and secure boot key management. |
| ADC | 12-bit SAR ADC, 1 Msps, up to 32 inputs - provides high-resolution sensor acquisition for motor control and battery monitoring. |
| FlexCAN | 1 × CAN-FD controller (ISO 11898-1) - supports data rates up to 5 Mbps for modern vehicle network diagnostics and actuation. |
Pinout & Package
FS32K116LIT0MFMR is packaged in a 48-pin LQFP (7 mm × 7 mm, 0.5 mm pitch), with 43 GPIOs supporting interrupt capability, dedicated JTAG/SWD debug pins, and segregated analog/digital power domains (VDD/VDDA, VREFH/VREFL).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA | Power supply inputs | Must be shorted on PCB with local decoupling; VDDA powers analog peripherals to ensure ADC/CMP accuracy. |
| VREFH, VREFL | ADC reference inputs | Set full-scale range for 12-bit conversion; VREFH ≤ VDDA + 0.1 V ensures monotonicity and linearity. |
| PTA0–PTA31, PTB0–PTB11 | GPIO multiplexed I/O | 43 total usable pins; each configurable as digital I/O, ADC input, UART TX/RX, or CAN signal - requires TRGMUX routing. |
| SWD_DIO, SWD_CLK | Debug interface | 2-pin Serial Wire Debug port - enables non-intrusive firmware update and real-time trace without JTAG pins. |
| CAN0_TX, CAN0_RX | FlexCAN physical interface | Differential pair routed to external transceiver; supports CAN-FD frames with flexible data rate switching. |
Key Features
| Feature | Design Value |
|---|---|
| System MPU | NXP's crossbar-level memory protection unit enforces access rights per master (CPU/DMA), meeting ASIL-B memory isolation requirements. |
| ECC Protection | End-to-end error correction on 128 KB flash and 25 KB SRAM prevents silent data corruption in safety-critical runtime environments. |
| CSEc Security Engine | Hardware-accelerated cryptographic functions (AES-128, SHA-256, ECDSA) enable secure boot, firmware authentication, and key provisioning. |
| Low-Power Timer Suite | LPTMR + LPIT + RTC provide sub-millisecond wake-up timing and calendar-based interrupts - essential for duty-cycled ECU sleep/wake cycles. |
| FlexCAN with FD | Single CAN-FD controller supports legacy CAN 2.0B and high-speed payload transmission (up to 64 bytes @ 5 Mbps) for diagnostic and control messaging. |
| ADC with DMA | 12-bit ADC with hardware-triggered DMA transfers eliminates CPU polling overhead - critical for deterministic sensor sampling in motor control loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K118LIT0MFMR | Same package and core, but with 256 KB flash and 32 KB SRAM - no change in clock speed or peripheral count. | Preferred where larger firmware image size or expanded RAM buffers are required for complex diagnostics or bootloader functionality. | Select when future firmware growth or dual-bank OTA capability justifies higher memory cost without altering hardware layout. |
| MC9S12XEP100MALR | Legacy S12X architecture (16-bit), 50 MHz max, no CSEc, no CAN-FD, 100-pin LQFP - not pin-compatible. | Used in legacy automotive platforms requiring long-term continuity; lacks modern security and FD bandwidth. | Only consider for drop-in replacement in existing S12X designs undergoing minimal requalification - not for new designs. |
Compared with S32K118LIT0MFMR, FS32K116LIT0MFMR trades flash/SRAM capacity for lower BOM cost while retaining identical safety architecture and CAN-FD capability; versus MC9S12XEP100MALR, it delivers ASIL-B readiness, hardware crypto, and 5 Mbps CAN-FD - but requires PCB redesign due to different pinout and package.
