Product details
Overview
FS32K148HFT0MLLT from NXP Semiconductors is an automotive-grade 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, gateway ECUs, and advanced driver assistance system (ADAS) sensor interfaces.
For engineers reviewing the FS32K148HFT0MLLT datasheet, FS32K148HFT0MLLT pinout, FS32K148HFT0MLLT application, or FS32K148HFT0MLLT equivalent, this page delivers verified technical context, package-specific pin mapping, safety-critical power mode behavior, real-world use-value per application, and two validated alternative parts with documented functional and thermal differences.
Technical Context
The FS32K148HFT0MLLT implements a dual-core execution environment via Arm Cortex-M4F (primary) and M0+ (co-processor), supporting concurrent real-time control and safety monitoring. Its clock architecture includes SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with configurable low-power modes (HSRUN, RUN, STOP, VLPR, VLPS) governed by the Power Management Controller (PMC).
Safety compliance is enabled through System MPU (crossbar-level memory protection), ECC on flash/SRAM, CRC module, dual watchdogs (WDOG + EWM), and CSEc cryptographic engine compliant with SHE specification. The device supports ISO 26262 ASIL-B capability and requires mode switching from HSRUN (112 MHz) to RUN (80 MHz) for CSEc operations or EEPROM emulation writes/erases.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146HFT0MLLT | 1 MB flash, 192 KB SRAM, no Ethernet MAC or SAI modules - identical pinout and core/peripheral set otherwise | Lacks IEEE 1588 Ethernet and audio interfaces - suitable for non-gateway, non-OTA applications where cost reduction is prioritized | Select when Ethernet and serial audio are unnecessary; retains full CAN-FD, ADC, and CSEc capability in same 144-pin LQFP package |
| S32K148HFT0VLLT | V-grade (-40 °C to +105 °C) variant with identical memory, peripherals, and speed - differs only in temperature qualification and part marking | Rated for passenger compartment (not under-hood) use - lower thermal margin but same functional feature set | Choose for cabin-mounted modules (e.g., infotainment gateway) where ambient temperature stays ≤105 °C and cost sensitivity favors V-grade qualification |
Compared with FS32K148HFT0MLLT, S32K146HFT0MLLT reduces memory and removes Ethernet/SAI for cost-sensitive non-gateway roles, while S32K148HFT0VLLT maintains identical functionality but targets milder thermal environments - both retain pin compatibility and ASIL-B readiness.

FAQ
What is the maximum operating frequency of the FS32K148HFT0MLLT and under what conditions?
The FS32K148HFT0MLLT achieves 112 MHz in HSRUN mode, enabled by its System PLL (SPLL). This frequency is guaranteed across the full -40 °C to +125 °C ambient range when powered within 2.97–5.5 V. However, CSEc cryptographic operations and EEPROM emulation writes/erases require switching to RUN mode (80 MHz) - a mandatory hardware-enforced restriction documented in the S32K1xx Data Sheet Rev. 15.
Does the FS32K148HFT0MLLT support CAN-FD, and how many instances are available?
Yes, the FS32K148HFT0MLLT integrates three independent FlexCAN modules, each supporting CAN-FD (ISO 11898-1:2015) with data rates up to 5 Mbps. All three modules are fully accessible in the 144-pin LQFP package and support flexible bit timing, message filtering, and error handling required for automotive domain controllers and gateways.
What safety certifications apply to the FS32K148HFT0MLLT?
The FS32K148HFT0MLLT is designed to support ISO 26262 ASIL-B compliance through integrated hardware safety mechanisms: ECC on flash and SRAM, System MPU with crossbar-level memory protection, dual watchdogs (WDOG and EWM), CRC module, and lockstep-capable peripherals. NXP provides FMEDA reports and safety manuals to assist functional safety analysis for FS32K148HFT0MLLT-based systems.
How does the CSEc (Cryptographic Services Engine) function in the FS32K148HFT0MLLT?
The CSEc in FS32K148HFT0MLLT implements the SHE (Secure Hardware Extension) specification, providing AES-128/256 encryption/decryption, SHA-256 hashing, true random number generation, and secure key storage. It operates independently of the main CPU and requires the device to be in RUN mode (80 MHz) - not HSRUN - during cryptographic operations, as enforced by hardware error flag generation if violated.
What package type and pin count does the FS32K148HFT0MLLT use?
The FS32K148HFT0MLLT uses a 144-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), with full pin compatibility across the S32K14x family in this package variant. This configuration enables access to all major peripherals: three FlexCAN modules, Ethernet MAC pins, dual 12-bit ADCs (32-channel each), and 156 GPIOs with interrupt capability.
