Overview
FS32K144UIT0VLHT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN operation, and integrated CSEc security engine. It features dual 12-bit ADCs (32-channel total), three FlexCAN modules (CAN-FD capable), and operates across -40 °C to 105 °C for body control module and powertrain sensor interface applications.
For engineers reviewing the FS32K144UIT0VLHT datasheet, FS32K144UIT0VLHT pinout, FS32K144UIT0VLHT application, or FS32K144UIT0VLHT equivalent, this page delivers verified specifications, package mapping to 144-pin LQFP, functional safety support up to ASIL-B, real-time timer architecture, and validated alternative parts for automotive ECU design.
Technical Context
The FS32K144UIT0VLHT implements a dual-core execution environment via Arm Cortex-M4F core with DSP extensions and single-precision FPU, supporting deterministic real-time control in HSRUN (112 MHz) and RUN (80 MHz) modes. Its memory subsystem includes ECC-protected 2 MB flash, 64 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM configurable as SRAM or EEPROM backup.
Power management integrates PMC with five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), while clocking uses SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz). Safety mechanisms include System MPU (crossbar-level memory protection), CRC module, WDOG, EWM, and CSEc cryptographic engine compliant with SHE specification.
