Product details
Overview
FS32K148UJT0VMHT from NXP Semiconductors is an automotive-grade Arm Cortex-M4F microcontroller with 2 MB flash, 256 KB SRAM (both with ECC), 112 MHz HSRUN/80 MHz RUN operation, and integrated CSEc security engine. It supports CAN-FD, Ethernet (10/100 Mbps with IEEE 1588), dual 12-bit ADCs (1 Msps), and operates across -40 °C to +125 °C for powertrain and chassis control applications.
For engineers reviewing the FS32K148UJT0VMHT datasheet, FS32K148UJT0VMHT pinout, FS32K148UJT0VMHT application, or FS32K148UJT0VMHT equivalent, this page delivers verified specifications, package mapping (100-pin LQFP), functional pin roles, safety-critical timing features, and validated alternative parts - all confirmed against NXP's S32K1xx Rev. 15 datasheet and orderable part number list.
Technical Context
The FS32K148UJT0VMHT implements a dual-core-capable architecture with Arm Cortex-M4F core (112 MHz HSRUN, 80 MHz RUN) and optional M0+ co-processor support via software configuration. Its memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, and 256 KB SRAM with ECC - all protected by NXP's system-level MPU at the AXBS-Lite crossbar switch.
Timing and communication are tightly integrated: eight FlexTimer modules (64 PWM/IC/OC channels), three FlexCAN interfaces (all with CAN-FD), one 10/100 Mbps Ethernet MAC with IEEE 1588 timestamping, and dual SAI modules. Power management supports five modes (HSRUN, RUN, STOP, VLPR, VLPS), with CSEc and EEPROM operations restricted to RUN mode (80 MHz) per hardware safety constraint.

FAQ
What is the maximum operating frequency of the FS32K148UJT0VMHT, and under what conditions?
The FS32K148UJT0VMHT achieves 112 MHz in HSRUN mode, but only when operating within its specified voltage and temperature envelope (2.97–5.5 V, -40 °C to +125 °C ambient). For CSEc cryptographic operations or FlexNVM EEPROM emulation, the device must drop to RUN mode at 80 MHz - a hardware-enforced restriction documented in the S32K1xx datasheet Rev. 15 Section 1.1 and Figure 3 notes.
Does the FS32K148UJT0VMHT support CAN-FD, and how many instances are available?
Yes, the FS32K148UJT0VMHT integrates three independent FlexCAN modules, all supporting CAN-FD (ISO 11898-1:2015) with bit rates up to 5 Mbps in FD mode. Each module has dedicated message buffers and supports programmable data field lengths up to 64 bytes - confirmed in the S32K1xx datasheet Section 3.1 Feature Comparison and Table 3 footnote.
What package type and pin count does the FS32K148UJT0VMHT use?
The FS32K148UJT0VMHT uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This matches the pin-to-pin compatibility defined for all S32K14x 100-pin variants per Figure 3 and Section 4.2 Ordering Information in the S32K1xx datasheet Rev. 15.
Is Ethernet functionality available on the FS32K148UJT0VMHT, and what standards does it support?
Yes, the FS32K148UJT0VMHT includes a full 10/100 Mbps Ethernet MAC with IEEE 1588-2008 Precision Time Protocol (PTP) hardware timestamping support. It implements MII/RMII interfaces and supports VLAN tagging, checksum offload, and multicast filtering - explicitly listed under "Communication" in Section 1.1 and Feature Comparison Figure 3.
How does the FS32K148UJT0VMHT handle functional safety requirements like ASIL-B?
The FS32K148UJT0VMHT meets ASIL-B requirements through hardware mechanisms including ECC on flash and SRAM, system-level MPU at the AXBS-Lite crossbar, dual watchdogs (WDOG + EWM), CRC module, and lockstep-ready peripherals. Its safety architecture is validated per ISO 26262 and documented in the S32K1xx Functional Safety Manual (FSM) referenced in the datasheet.
