Product details
Overview
FS32K142MAT0MLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 256 KB flash, 256 KB SRAM, and support for HSRUN mode at 112 MHz. It integrates CSEc security engine, dual 12-bit ADCs (up to 32 channels), FlexCAN with optional CAN-FD, and operates across -40 °C to +125 °C ambient temperature. Designed for body control modules and gateway ECUs requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K142MAT0MLLT datasheet, FS32K142MAT0MLLT pinout, FS32K142MAT0MLLT application, or FS32K142MAT0MLLT equivalent, key selection considerations include its M-grade temperature rating, LQFP-48 package, 112 MHz HSRUN capability, CSEc cryptographic acceleration, and compatibility with S32K1xx SDK and NXP S32 Design Studio toolchain.
Technical Context
The FS32K142MAT0MLLT implements a dual-core execution environment with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and supports deterministic real-time operation via eight FlexTimer modules (64 PWM/IC/OC channels), LPIT, LPTMR, and PDB. Its memory subsystem includes ECC-protected 256 KB flash, 256 KB SRAM, 4 KB FlexRAM, and QuadSPI with HyperBus™ support.
Power management is handled by PMC with five modes (HSRUN, RUN, STOP, VLPR, VLPS); CSEc and EEPROM operations require mode switching from HSRUN to RUN (80 MHz) due to hardware-enforced isolation. Safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM, and ECC on flash/SRAM - all aligned with ISO 26262 ASIL-B requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144HAT0MLLT | 512 KB flash, 512 KB SRAM, same M-grade temp and LQFP-48 package; adds second FlexCAN and extra LPUART. | Better suited for multi-bus gateways requiring dual CAN domains or higher firmware footprint. | Select when >256 KB flash is needed for bootloader + application + OTA staging, or dual CAN is mandatory. |
| FS32K118MT0VLQR | Arm Cortex-M0+ core, 128 KB flash, 48-pin LQFP, V-grade (-40 °C to +105 °C), no CSEc or FlexCAN FD. | Targeted at cost-sensitive, non-safety-critical body nodes where ASIL-B is not required. | Choose for simpler LIN-only modules or interior switches where lower performance and security are acceptable. |
