Product details
Overview
FS32K142UAT0VLFT from NXP Semiconductors is an automotive-grade Arm® Cortex-M4F microcontroller designed for real-time control in safety-critical ECUs. It operates at up to 112 MHz (HSRUN mode), features 256 KB flash with ECC, 64 KB FlexNVM for EEPROM emulation, and supports -40 °C to 105 °C ambient operation in a 100-pin LQFP package - deployed in body control modules and powertrain sensor interfaces.
For engineers reviewing the FS32K142UAT0VLFT datasheet, FS32K142UAT0VLFT pinout, FS32K142UAT0VLFT application, or FS32K142UAT0VLFT equivalent, key selection considerations include HSRUN/RUN mode switching constraints for CSEc and EEPROM operations, CAN-FD readiness via FlexCAN, ASIL-B capable safety architecture, and 100-pin LQFP I/O count (up to 89 GPIOs) with configurable low-power peripherals.
Technical Context
The FS32K142UAT0VLFT integrates an Arm Cortex-M4F core with single-precision FPU and DSP extensions, executing at 112 MHz in HSRUN mode (1.25 DMIPS/MHz) and 80 MHz in RUN mode. Its clock system includes SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz), with dedicated TCLK (20 MHz) and SWD_CLK (25 MHz) for debug timing.
Power management implements five modes - HSRUN, RUN, STOP, VLPR, VLPS - coordinated by the PMC; CSEc cryptographic operations and FlexNVM writes are restricted to RUN mode (80 MHz) due to hardware arbitration conflict in HSRUN. Memory protection uses NXP's system MPU at the AXBS-Lite crossbar level, not Arm Core MPU.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144UAT0VLFT | 512 KB flash, 128 KB SRAM, adds Ethernet MAC and second SAI - same 100-pin LQFP footprint and pin-compatible. | Required for gateway applications needing 10/100 Mbps Ethernet and dual audio streams; not needed for standalone BCM or EPS. | Select FS32K144UAT0VLFT when Ethernet connectivity or >256 KB RAM is mandatory; FS32K142UAT0VLFT suffices for cost-sensitive control-only nodes. |
| FS32K118MLT0VLQ | Arm Cortex-M0+, 48 MHz max, 128 KB flash, 16 KB SRAM, no CSEc or FlexCAN FD - 48-pin LQFP, lower I/O count. | Suitable for LIN-only body nodes (e.g., mirror control); lacks HSRUN mode, CAN-FD, and ASIL-B safety mechanisms. | Choose FS32K118MLT0VLQ only for non-safety-critical, low-compute LIN slave applications where BOM cost and board space are primary constraints. |
Compared with FS32K144UAT0VLFT, FS32K142UAT0VLFT trades flash/SRAM capacity and Ethernet for lower unit cost and identical pinout - ideal for control-focused ECUs.
