Product details
Overview
FS32K148HAT0MLQT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for safety-critical body electronics and powertrain control. It operates at up to 112 MHz in HSRUN mode, integrates 2 MB ECC-protected flash, 256 KB SRAM with ECC, and supports -40 °C to +125 °C ambient operation. Its dual-core debug architecture, CSEc security engine, and FlexCAN with optional CAN-FD make it suitable for ASIL-B compliant vehicle gateway modules.
For engineers reviewing the FS32K148HAT0MLQT datasheet, FS32K148HAT0MLQT pinout, FS32K148HAT0MLQT application, or FS32K148HAT0MLQT equivalent, key selection considerations include its 176-pin LQFP package, 112 MHz HSRUN/80 MHz RUN dual-frequency capability, CSEc cryptographic acceleration, 3× FlexCAN (with CAN-FD), and 156 GPIOs - all validated for automotive functional safety per ISO 26262 up to ASIL-B.
Technical Context
The FS32K148HAT0MLQT implements a dual-voltage-domain Arm Cortex-M4F core with integrated FPU and DSP extensions, coupled with a dedicated Power Management Controller (PMC) supporting five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS). Its clock system includes SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), enabling precise timing control across operating modes.
Memory subsystem features ECC on 2 MB flash and 256 KB SRAM, plus 64 KB FlexNVM for EEPROM emulation and 4 KB FlexRAM configurable as SRAM or EEPROM. Peripheral integration includes three FlexCAN modules (CAN-FD capable), two SAI interfaces, 10/100 Mbps Ethernet with IEEE 1588, and eight FlexTimer modules delivering up to 64 PWM/IC/OC channels - all accessible via AXBS-Lite crossbar switch with eDMA support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K146HAT0MLQT | 1 MB flash, 192 KB SRAM, no Ethernet or SAI - same 176-pin LQFP package and pin-compatible. | Lacks IEEE 1588 Ethernet and audio interfaces - suitable for non-gateway body controllers requiring lower memory footprint. | Select when Ethernet/SAI are unnecessary and cost optimization is prioritized without changing PCB layout. |
| FS32K148UAT0MLQT | Same 2 MB flash and peripherals, but rated for -40 °C to +105 °C (V-grade) instead of +125 °C (M-grade). | Lower thermal rating limits use in under-hood locations - intended for cabin or chassis modules with milder thermal profiles. | Choose for interior applications where extended temperature range is not required, reducing qualification burden. |
Compared with FS32K148HAT0MLQT, FS32K146HAT0MLQT reduces memory and connectivity for cost-sensitive BCMs, while FS32K148UAT0MLQT trades thermal margin for simplified qualification - both retain identical pinout and software compatibility, enabling scalable platform design.

FAQ
What is the maximum operating frequency of the FS32K148HAT0MLQT and under what conditions?
The FS32K148HAT0MLQT achieves 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode is limited to ambient temperatures up to +105 °C, while RUN mode supports the full -40 °C to +125 °C M-grade range. Operation above 80 MHz at 125 °C ambient is not permitted per thermal specifications in the datasheet.
Does the FS32K148HAT0MLQT support CAN-FD, and how many instances are available?
Yes, the FS32K148HAT0MLQT integrates three FlexCAN modules, each supporting CAN-FD protocol per ISO 11898-1:2015. All three channels are fully functional in the 176-pin LQFP package, with dedicated TX/RX pins and message RAM configured for high-speed data transfer up to 5 Mbps.
What security features does the FS32K148HAT0MLQT include, and how are they implemented?
The FS32K148HAT0MLQT includes the Cryptographic Services Engine (CSEc), which implements AES-128/256, SHA-256, HMAC, RSA-2048, and true random number generation. CSEc operates independently of the CPU and supports secure boot, key provisioning, and encrypted firmware updates - all verified per SHE v1.1 specification.
Is QuadSPI supported on the FS32K148HAT0MLQT in the 176-pin LQFP package?
No, QuadSPI is explicitly excluded for the FS32K148HAT0MLQT in the 176-pin LQFP package, as noted in the datasheet Feature Comparison table. QuadSPI is only available on MAPBGA and select LQFP variants (e.g., 100-pin LQFP), making external HyperBus™ memory expansion unavailable for this specific FS32K148HAT0MLQT configuration.
What is the role of the System MPU in the FS32K148HAT0MLQT, and how does it differ from Arm Core MPU?
The FS32K148HAT0MLQT uses NXP's System MPU - a crossbar-level memory protection unit that enforces access rights for all masters (CPU, DMA, Ethernet). Unlike the Arm Core MPU (absent in this device), it protects against unauthorized peripheral-initiated memory accesses, fulfilling ASIL-B memory isolation requirements per ISO 26262.
