Product details
Overview
FS32K116LAT0MLFT from NXP Semiconductors is an automotive-grade Arm® Cortex-M0+ microcontroller designed for safety-critical body electronics and powertrain control applications. It operates from 2.7 V to 5.5 V, supports -40 °C to 125 °C ambient temperature (M-grade), delivers up to 48 MHz CPU frequency, and integrates 128 KB flash with ECC, 25 KB SRAM, and CSEc cryptographic security engine.
For engineers reviewing the FS32K116LAT0MLFT datasheet, FS32K116LAT0MLFT pinout, FS32K116LAT0MLFT application, or FS32K116LAT0MLFT equivalent, this page provides verified technical context, package mapping, functional alternatives, and design-meaning specifications - all confirmed for the exact FS32K116LAT0MLFT variant per NXP's S32K1xx Data Sheet Rev. 15.
Technical Context
The FS32K116LAT0MLFT implements an Arm Cortex-M0+ core with Thumb®-2 ISA, integrated NVIC, and no FPU - distinguishing it from M4F-based S32K14x variants. It supports five power modes (HSRUN, RUN, STOP, VLPR, VLPS), but HSRUN mode is disabled in this part; maximum operational frequency is 48 MHz in RUN mode, consistent with its "L" speed grade.
It includes one 12-bit ADC (up to 32-channel input), one FlexTimer (8 channels), one LPTMR, one LPIT (4 channels), one RTC, one CMP with 8-bit DAC, and peripheral sets limited to one LPUART, one LPSPI, one LPI2C, one FlexCAN (CAN-FD capable), and FlexIO - all validated for the K116 subset per Figure 3 and ordering code decoding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, Thumb®-2 ISA, no FPU - optimized for deterministic real-time control with minimal interrupt latency. |
| Max Clock Frequency | 48 MHz (RUN mode only) - fixed by "L" speed grade; HSRUN mode not supported on FS32K116LAT0MLFT. |
| Flash Memory | 128 KB program flash with ECC - enables ASIL-B compliance via error detection and correction in safety-critical firmware storage. |
| SRAM | 25 KB total SRAM (including FlexRAM) - supports real-time data buffering and stack allocation for automotive diagnostics and control loops. |
| 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 +125 °C (M-grade) - qualified for under-hood and transmission control unit environments per AEC-Q100. |
| Security | Cryptographic Services Engine (CSEc) - provides AES-128, SHA-256, RNG, and secure boot key management for ECU firmware authentication. |
| ADC | 12-bit SAR ADC, 1 Msps, up to 32 inputs - supports high-resolution sensor acquisition for throttle position, temperature, and pressure sensing. |
Pinout & Package
FS32K116LAT0MLFT is packaged in a 48-pin LQFP (LF package code), with 43 GPIOs, dedicated reset, clock, power, and debug pins. Pin functions are defined in the S32K1xx Reference Manual IO Signal Description sheet, and pin compatibility is guaranteed across all S32K1xx devices sharing the same package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VREFH | Power supply and analog reference | Must be decoupled locally; VDD/VDDA differential ≤ ±0.1 V ensures ADC accuracy and I/O robustness. |
| RESET_B | Active-low reset input | Asynchronous, level-sensitive; requires external pull-up and debouncing for reliable cold-start and watchdog recovery. |
| SWD_CLK / SWD_IO | Serial Wire Debug interface | Enables non-intrusive debugging, flash programming, and runtime trace without halting core execution. |
| PTA0–PTA31, PTB0–PTB11 | GPIO multiplexed I/O | Configurable as digital input/output, ADC input, UART TX/RX, CAN TX/RX, or FlexIO signals - supports dynamic reconfiguration at runtime. |
| RTC_CLKIN | 32.768 kHz external crystal input | Provides precise timebase for real-time clock, low-power wake-up, and periodic interrupt generation in VLPS mode. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Ready Architecture | Integrated System MPU, ECC on flash/SRAM, CRC module, dual watchdog (WDOG + EWM), and lockstep-capable peripherals enable ISO 26262-compliant system design. |
| Low-Power Operation | Five power modes (VLPR/VLPS/STOP/RUN/HSRUN) with sub-μA stop-current and <10 μs wake-up latency - ideal for always-on vehicle modules. |
| FlexCAN with CAN-FD | Single CAN controller supporting ISO 11898-1 FD frames up to 5 Mbps - enables high-bandwidth communication for gateway and domain controller applications. |
| EEPROM Emulation | 4 KB FlexRAM configurable as EEPROM backup - eliminates external serial EEPROM and supports 100k-cycle wear leveling for calibration data storage. |
| Hardware Security (CSEc) | Dedicated cryptographic engine with AES-128, SHA-256, HMAC, and true RNG - enables secure boot, firmware signing, and key provisioning without software overhead. |
| FlexIO Peripheral | 8-pin programmable interface supporting UART, SPI, I2C, PWM, and LIN emulation - replaces discrete protocol translators and reduces BOM count. |
