Overview
FS32K148HST0MLQT 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), Ethernet MAC (10/100 Mbps with IEEE 1588), and operates from -40 °C to +125 °C - designed for body control modules and ADAS domain controllers.
For engineers reviewing the FS32K148HST0MLQT datasheet, FS32K148HST0MLQT pinout, FS32K148HST0MLQT application, or FS32K148HST0MLQT equivalent, this page delivers verified specifications, package mapping (144-pin LQFP), functional pinout, safety-critical timing behavior, and validated alternative options aligned with ISO 26262 ASIL-B requirements.
Technical Context
The FS32K148HST0MLQT implements a dual-core execution context: Arm Cortex-M4F core with FPU and DSP extensions runs at up to 112 MHz in HSRUN mode (requiring ≥2.97 V when PLL engaged), while supporting concurrent low-power operation via PMC-managed modes including RUN, STOP, VLPR, and VLPS. Its memory subsystem includes ECC-protected 2 MB flash, 256 KB SRAM, 64 KB FlexNVM (with EEPROM emulation), and 4 KB FlexRAM.
Peripherals are routed through AXBS-Lite crossbar switch with eDMA (16-channel, 63 request sources) and TRGMUX for deterministic timing. Safety mechanisms include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM watchdogs, and CSEc cryptographic engine compliant with SHE specification - all validated for ASIL-B system integration per ISO 26262.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146HFT0MLQT | 1 MB flash, 192 KB SRAM, no Ethernet MAC or SAI - identical 144-pin LQFP package and pinout. | Lacks IEEE 1588 Ethernet and audio interfaces - suitable for non-gateway body ECUs requiring CAN-FD and LIN only. | Select when Ethernet and SAI are unnecessary and cost optimization is prioritized without changing PCB layout. |
| S32K148HRT0MLQT | Same 2 MB flash, 256 KB SRAM, and peripherals but rated for -40 °C to +105 °C (V-grade) instead of +125 °C (M-grade). | Lower temperature rating limits use to cabin-mounted modules - not qualified for under-hood deployment. | Choose for infotainment or instrument cluster applications where ambient temperature stays below 105 °C and full M-grade qualification is not required. |
Compared with FS32K148HST0MLQT, S32K146HFT0MLQT reduces memory and removes Ethernet to lower BOM cost while retaining pin compatibility, whereas S32K148HRT0MLQT maintains full feature parity but sacrifices high-temp qualification - enabling trade-offs between thermal robustness, connectivity, and system cost.

FAQ
What is the maximum operating frequency of the FS32K148HST0MLQT and under what conditions?
The FS32K148HST0MLQT achieves 112 MHz in HSRUN mode, but only when supplied with ≥2.97 V (due to PLL requirements); at lower voltages, it defaults to 80 MHz RUN mode. This dual-frequency capability allows dynamic performance scaling - critical for meeting real-time deadlines in safety-critical loops while minimizing power during idle phases. The FS32K148HST0MLQT datasheet specifies voltage-dependent frequency limits in Section 5.2.
Does the FS32K148HST0MLQT support CAN-FD, and how many instances are available?
Yes, the FS32K148HST0MLQT integrates three independent FlexCAN modules, all supporting CAN-FD protocol (ISO 11898-1:2015) with bit rates up to 5 Mbps. Each module includes dedicated message RAM, flexible filtering, and error counters - enabling simultaneous high-bandwidth communication on powertrain, chassis, and body networks. This capability is confirmed in the S32K1xx Data Sheet Figure 3 and Section 1.1.
How does the CSEc security engine in the FS32K148HST0MLQT operate, and what cryptographic functions does it support?
The FS32K148HST0MLQT includes a Cryptographic Services Engine (CSEc) compliant with the SHE specification, providing AES-128 encryption/decryption, SHA-256 hashing, true random number generation (TRNG), and secure key provisioning. It operates independently of the main CPU and requires switching to RUN mode (80 MHz) for CSEc operations - as HSRUN mode disables flash writes/erases. This design ensures secure boot and OTA update integrity without compromising real-time performance.
What is the temperature grade of the FS32K148HST0MLQT, and how does it affect its use cases?
The FS32K148HST0MLQT carries an M-grade temperature rating: -40 °C to +125 °C ambient, with a 135 °C junction limit in RUN mode. This qualifies it for under-hood automotive applications such as engine control, transmission, and EPS - where sustained high temperatures occur. The datasheet explicitly ties this rating to RUN mode operation (≤80 MHz), distinguishing it from HSRUN mode's 105 °C limit - a key constraint for thermal-aware system design.
Is the FS32K148HST0MLQT pin-compatible with other S32K1xx devices, and which packages share the same footprint?
Yes, all S32K1xx devices sharing the 144-pin LQFP package - including FS32K148HST0MLQT, S32K146HFT0MLQT, and S32K144HFT0MLQT - are fully pin-to-pin compatible per NXP's documentation (Figure 3, "S32K1xx product series comparison"). This enables hardware reuse across product variants; however, peripheral availability depends on silicon configuration - e.g., Ethernet pins are unused on non-K148 derivatives despite physical presence.
