Overview
FX32K148HAT0MLQR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), and dual 12-bit ADCs. It operates at up to 112 MHz in HSRUN mode (−40 °C to +125 °C ambient), supports CAN-FD, FlexCAN, Ethernet (10/100 Mbps with IEEE 1588), and cryptographic services via CSEc. It targets body control modules and gateway ECUs requiring ASIL-B functional safety compliance.
For engineers reviewing the FX32K148HAT0MLQR datasheet, FX32K148HAT0MLQR pinout, FX32K148HAT0MLQR application, or FX32K148HAT0MLQR equivalent, this page delivers verified specifications, package mapping (100-pin LQFP), validated alternatives, real-world use scenarios, and supply-chain support for automotive embedded design and production.
Technical Context
The FX32K148HAT0MLQR implements a dual-core architecture with Arm Cortex-M4F as primary execution core and optional M0+ for low-power co-processing. Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), enabling dynamic mode switching between HSRUN, RUN, STOP, VLPR, and VLPS.
Memory subsystem includes ECC-protected 2 MB program flash, 64 KB FlexNVM (with EEPROM emulation), 256 KB SRAM, and 4 KB FlexRAM configurable as SRAM or EEPROM. Safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM, and CSEc supporting SHE-compliant cryptographic operations - all qualified per ISO 26262 up to ASIL-B.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| ASIL-B Functional Safety Support | Integrated System MPU, ECC on flash/SRAM, CRC engine, and lockstep-capable peripherals enable ISO 26262-compliant system design. |
| Flexible Power Management | Five low-power modes (HSRUN/RUN/STOP/VLPR/VLPS) with clock gating and peripheral isolation reduce active current to <10 µA in VLPS. |
| QuadSPI with HyperBus™ | Enables direct XIP execution from external NOR flash or PSRAM, expanding code space beyond on-chip 2 MB flash. |
| FlexIO Module | Configurable logic block supporting UART, SPI, I2C, LIN, PWM, or custom protocols - eliminates need for external glue logic in mixed-interface designs. |
| Real-Time Counter (RTC) | 32-bit counter with 32 kHz external clock input and alarm/wakeup capability - provides deterministic timekeeping independent of CPU state. |
| Secure Boot & Key Management | CSEc enforces authenticated boot, key wrapping, and secure storage of secrets - prevents unauthorized firmware updates and cloning. |

FAQ
What is the maximum operating frequency of FX32K148HAT0MLQR, and under what conditions?
FX32K148HAT0MLQR operates at up to 112 MHz in HSRUN mode, but only within −40 °C to +125 °C ambient temperature and with VDD ≥ 2.97 V when PLL is engaged. For CSEc cryptographic operations or EEPROM writes/erase, it must drop to 80 MHz RUN mode - a hardware-enforced restriction to ensure memory integrity and timing safety.
Does FX32K148HAT0MLQR support CAN-FD, and how many instances are available?
Yes, FX32K148HAT0MLQR supports three FlexCAN modules, all capable of CAN-FD operation per ISO 11898-1:2015. Each channel supports bit rates up to 5 Mbps in FD mode and includes message filtering, FIFO buffering, and loopback self-test - essential for high-bandwidth vehicle networking in modern gateways and domain controllers.
What safety certifications apply to FX32K148HAT0MLQR?
FX32K148HAT0MLQR is qualified per ISO 26262 up to ASIL-B, with integrated safety mechanisms including ECC on flash/SRAM, System MPU for crossbar-level memory protection, CRC engine, WDOG/EWM watchdogs, and lockstep-ready peripherals. Its M-grade temperature rating (−40 °C to +125 °C) further validates suitability for under-hood automotive safety applications.
Can FX32K148HAT0MLQR execute code directly from external memory?
Yes, FX32K148HAT0MLQR supports Execute-in-Place (XIP) from external memory via its QuadSPI interface with HyperBus™ compatibility. This allows direct execution from external NOR flash or PSRAM, extending effective code space beyond the on-chip 2 MB flash - critical for large AUTOSAR stacks or OTA update staging.
What is the role of CSEc in FX32K148HAT0MLQR, and which cryptographic functions does it support?
CSEc (Cryptographic Services Engine) in FX32K148HAT0MLQR implements SHE (Secure Hardware Extension)-compliant functions including AES-128/256 encryption/decryption, SHA-256 hashing, true random number generation (TRNG), secure key storage, and secure boot verification. It operates independently of the main CPU and is mandatory for secure firmware updates and ECU authentication in automotive deployments.
