Product details
Overview
FS32K144HRT0VLLR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), and support for HSRUN mode at 112 MHz. It integrates FlexCAN with optional CAN-FD, dual 12-bit ADCs (up to 32 channels), CSEc security engine, and operates across -40 °C to +105 °C ambient temperature. It is used in body control modules requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K144HRT0VLLR datasheet, FS32K144HRT0VLLR pinout, FS32K144HRT0VLLR application, or FS32K144HRT0VLLR equivalent, key selection criteria include its 144-pin LQFP package, dual-core debug support (SWD/JTAG), HSRUN/RUN power mode switching constraints for EEPROM/CSEc operations, and CAN-FD readiness in automotive network gateways.
Technical Context
The FS32K144HRT0VLLR implements a dual-mode Arm Cortex-M4F core with deterministic real-time execution: HSRUN mode delivers 112 MHz peak performance (1.25 DMIPS/MHz) but disables CSEc and EEPROM writes, requiring runtime switch to 80 MHz RUN mode for secure operations. Its AXBS-Lite crossbar switch enables concurrent access by CPU, eDMA, and Ethernet MAC to protected memory regions via NXP's system MPU - not Arm's core MPU - enforcing ASIL-B–capable memory isolation.
Peripherals are partitioned by power domain: LPUART/LPSPI/LPI2C retain functionality in VLPR/VLPS low-power modes, while QuadSPI with HyperBus™ support and IEEE-1588 Ethernet require HSRUN/RUN. The TRGMUX routes signals to FTM, PDB, LPIT, and ADC, enabling synchronized timing across motor control and sensor acquisition subsystems without CPU intervention.
