Product details
Overview
FS32K148HET0VLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM, and integrated CSEc security engine. It operates at up to 112 MHz in HSRUN mode (−40 °C to +105 °C), supports CAN-FD, Ethernet (10/100 Mbps), and IEEE-1588 timing - deployed in vehicle body control modules requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K148HET0VLLT datasheet, FS32K148HET0VLLT pinout, FS32K148HET0VLLT application, or FS32K148HET0VLLT equivalent, this page delivers verified package mapping (100-pin LQFP), confirmed pin-to-pin compatibility within S32K14x family, real-time power mode constraints (HSRUN vs. RUN for CSEc/EEPROM), and validated alternative part selection guidance for automotive ECU redesigns.
Technical Context
The FS32K148HET0VLLT implements a dual-core-capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN), integrated FPU, DSP extensions, and configurable NVIC. Its memory subsystem includes ECC-protected 2 MB flash, 256 KB SRAM, 64 KB FlexNVM for EEPROM emulation, and 4 KB FlexRAM - all managed via NXP's system-level MPU enforcing crossbar-switch-based access control across DMA, Ethernet, and CPU masters.
Timing and communication are tightly coupled: the device integrates three FlexCAN modules (all with CAN-FD support), one 10/100 Mbps IEEE-1588 Ethernet MAC, two SAI interfaces, QuadSPI with HyperBus™, and eight FlexTimer modules (64 PWM/IC/OC channels). Power management includes five low-power modes (HSRUN, RUN, STOP, VLPR, VLPS), with explicit mode-switching requirements for CSEc execution and EEPROM operations.

FAQ
What is the maximum operating frequency of the FS32K148HET0VLLT and under which conditions?
The FS32K148HET0VLLT achieves 112 MHz in HSRUN mode, guaranteed across −40 °C to +105 °C ambient temperature. However, CSEc cryptographic operations and EEPROM writes/erase are prohibited in HSRUN mode; the device must switch to RUN mode (80 MHz) to execute those functions safely and reliably.
Does the FS32K148HET0VLLT support IEEE-1588 Precision Time Protocol (PTP)?
Yes, the FS32K148HET0VLLT integrates a 10/100 Mbps Ethernet MAC with full IEEE-1588 hardware timestamping support, enabling sub-microsecond time synchronization for distributed automotive systems such as zonal gateways and ADAS sensor fusion nodes.
What package type and pin count does the FS32K148HET0VLLT use?
The FS32K148HET0VLLT is supplied in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. It is pin-to-pin compatible with other S32K14x family members offered in the same 100-pin LQFP variant, simplifying hardware reuse across product variants.
How does the CSEc (Cryptographic Services Engine) function in the FS32K148HET0VLLT?
The CSEc in FS32K148HET0VLLT implements SHE-compliant cryptographic primitives including AES-128 encryption/decryption, SHA-256 hashing, and true random number generation. It operates only in RUN mode (80 MHz), not HSRUN, and provides secure key storage and boot authentication to meet UNECE R155 compliance requirements.
Can the FS32K148HET0VLLT support CAN-FD communication, and how many controllers are available?
Yes, the FS32K148HET0VLLT includes three independent FlexCAN modules, all supporting CAN-FD (ISO 11898-1 FD) up to 5 Mbps data phase. Each controller supports message filtering, FIFO buffering, and bus-off recovery - essential for high-bandwidth vehicle network backbones.
What is the flash and SRAM memory configuration of the FS32K148HET0VLLT?
The FS32K148HET0VLLT integrates 2 MB of program flash memory with ECC, 256 KB of ECC-protected SRAM, 64 KB of FlexNVM for EEPROM emulation, and 4 KB of FlexRAM configurable as SRAM or EEPROM backup - all accessible via AXBS-Lite crossbar for deterministic multi-master arbitration.
