For engineers reviewing the FS32K116LAT0MLFR datasheet, FS32K116LAT0MLFR pinout, FS32K116LAT0MLFR application, or FS32K116LAT0MLFR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in NXP's S32K1xx Rev. 15 datasheet and orderable part number list.

Technical Context

The FS32K116LAT0MLFR implements an Arm Cortex-M0+ core optimized for ASIL-B compliance, with integrated System MPU for memory protection at the crossbar switch level and dedicated low-power modes (RUN, STOP, VLPR, VLPS) managed by the Power Management Controller. Its clock system combines FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SOSC (4–40 MHz) with SPLL support up to 48 MHz - no HSRUN mode capability as confirmed by K116 feature set.

It includes one 12-bit ADC (1 Msps, up to 32 channels), one Analog Comparator with 8-bit DAC, one LPTMR, one LPIT (4 channels), two FlexTimers (16-bit, 16 total channels), and a 32-bit RTC. Memory architecture comprises 128 KB program flash with ECC, 2 KB FlexNVM for EEPROM emulation, 25 KB SRAM (including FlexRAM), and 2 KB cache - all aligned with S32K116-specific allocations in the feature comparison table.

Key Specifications

Pinout & Package

FS32K116LAT0MLFR is packaged in a 48-pin LQFP (LF package code), with 43 GPIOs, 4 dedicated analog inputs, and pin-compatible layout across S32K11x family variants in the same package. The device uses standard LQFP-48 footprint (10 mm × 10 mm, 0.5 mm pitch) and supports full JTAG/SWD debug access via dedicated TMS/TCK/TDO/TDI/SWCLK/SWDIO pins.

FAQ

What is the maximum operating frequency of the FS32K116LAT0MLFR?

The FS32K116LAT0MLFR operates at up to 48 MHz in RUN mode, as defined by its "L" speed grade (per Figure 5 ordering information). Unlike S32K14x devices, it does not support HSRUN mode or 112 MHz operation - its Arm Cortex-M0+ core is rated for 48 MHz maximum, consistent with S32K116 feature allocation in the datasheet's comparison tables.

Does the FS32K116LAT0MLFR support CAN FD?

No, the FS32K116LAT0MLFR does not support CAN FD. Per the S32K1xx feature comparison (Figure 3), only S32K14x and S32K14xW devices include CAN FD capability. The FS32K116LAT0MLFR includes one FlexCAN 2.0B module supporting up to 1 Mbps classical CAN, as confirmed by its "F" ordering option absence and K116 row in the peripheral matrix.

What package type and pin count does FS32K116LAT0MLFR use?

The FS32K116LAT0MLFR uses a 48-pin LQFP package (package code "LF"), measuring 10 mm × 10 mm with 0.5 mm pitch. This matches the "48-pin LQFP" option listed for S32K11x devices in Figure 3 and is explicitly supported in the S32K1xx_Orderable_Part_Number_List.xlsx referenced in Section 4.1.

Is the FS32K116LAT0MLFR qualified for automotive applications?

Yes, the FS32K116LAT0MLFR is AEC-Q100 Grade 1 qualified (−40 °C to +125 °C), with built-in functional safety features including System MPU, ECC on flash/SRAM, dual watchdogs (WDOG and EWM), and CSEc - enabling ASIL-B compliance in automotive body electronics per ISO 26262.

Can FS32K116LAT0MLFR execute CSEc operations in RUN mode?

Yes, FS32K116LAT0MLFR can execute CSEc cryptographic operations in RUN mode. Unlike HSRUN-capable devices, the FS32K116LAT0MLFR operates exclusively at up to 48 MHz - well within the safe execution range for CSEc, EEPROM emulation, and flash writes, as no HSRUN mode restriction applies to this variant.
