Product details
Overview
FS32K144HAT0MMHR 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/80 MHz RUN operation, and integrated CSEc security engine. It supports CAN-FD, FlexCAN, LPUART/LIN, LPSPI, LPI2C, FlexIO, and 12-bit ADCs - deployed in vehicle body control modules requiring ASIL-B functional safety compliance.
For engineers reviewing the FS32K144HAT0MMHR datasheet, FS32K144HAT0MMHR pinout, FS32K144HAT0MMHR application, or FS32K144HAT0MMHR equivalent, this page delivers verified specifications, package mapping to 144-pin LQFP, thermal limits (−40 °C to +125 °C), power mode behavior (HSRUN/RUN/STOP/VLPR/VLPS), and validated alternative part options for automotive ECU design.
Technical Context
The FS32K144HAT0MMHR implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN, 80 MHz RUN) and optional M0+ co-processor support via software configuration. Its memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system MPU at crossbar switch level.
Peripherals include three FlexCAN modules (with CAN-FD), up to eight 16-bit FlexTimers (64 channels total), two 12-bit ADCs (32-channel input per module), and low-power interfaces (LPUART, LPSPI, LPI2C) supporting DMA. Clocking uses SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with explicit mode restrictions: CSEc and EEPROM operations require RUN mode (80 MHz), not HSRUN.

FAQ
What is the maximum operating frequency of the FS32K144HAT0MMHR in HSRUN mode?
The FS32K144HAT0MMHR operates at up to 112 MHz in HSRUN mode, delivering 1.25 Dhrystone MIPS per MHz. This high-frequency mode is restricted to non-security operations - CSEc cryptographic functions and EEPROM writes must execute in RUN mode (80 MHz) to avoid error flag assertion. The device automatically transitions between modes via software-controlled PMC registers.
Does the FS32K144HAT0MMHR support CAN-FD, and how many channels are available?
Yes, the FS32K144HAT0MMHR integrates three independent FlexCAN modules, each supporting CAN-FD (ISO 11898-1). All three channels are fully functional in the 144-pin LQFP package, with dedicated TX/RX pins routed to separate differential pairs. CAN-FD enables data rates up to 5 Mbps and payloads up to 64 bytes, essential for high-bandwidth chassis and ADAS networks.
What safety certifications apply to the FS32K144HAT0MMHR?
The FS32K144HAT0MMHR is designed to support ASIL-B compliance per ISO 26262, featuring ECC on flash and SRAM, system MPU for memory protection, dual watchdogs (WDOG and EWM), CRC module, and lockstep-capable peripherals. While the device itself is not pre-certified, its safety mechanisms are documented in NXP's S32K1xx Functional Safety Manual (FSM) and supported by certified S32DS SDK safety libraries.
Can the FS32K144HAT0MMHR execute secure boot and firmware updates?
Yes, the FS32K144HAT0MMHR includes the Cryptographic Services Engine (CSEc), which implements SHE-compliant secure boot, AES-128/256 encryption, SHA-256 hashing, and true random number generation. Secure firmware updates are enabled via authenticated image validation and encrypted OTA download - all executed within trusted execution environment boundaries defined by CSEc key partitioning.
What is the pin-compatible upgrade path from FS32K144HAT0MMHR?
The FS32K146HAT0MMHR is pin-compatible with FS32K144HAT0MMHR in the 144-pin LQFP package and shares identical peripheral pinouts. It upgrades flash to 1 MB, SRAM to 512 KB, and adds 10/100 Mbps Ethernet MAC and dual SAI interfaces - enabling seamless migration for gateway or domain controller designs requiring higher bandwidth or audio capabilities.
