Product details
Overview
FS32K148UAT0VMHR 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/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 from -40 °C to +125 °C - deployed in vehicle body control modules requiring functional safety up to ASIL-B.
For engineers reviewing the FS32K148UAT0VMHR datasheet, FS32K148UAT0VMHR pinout, FS32K148UAT0VMHR application, or FS32K148UAT0VMHR equivalent, key selection considerations include its M-grade temperature rating, 176-pin LQFP package, FlexCAN with FD support, CSEc cryptographic acceleration, and mandatory mode-switching (RUN at 80 MHz) for EEPROM/CSEc operations.
Technical Context
The FS32K148UAT0VMHR implements a dual-core architecture with Arm Cortex-M4F (primary) and Cortex-M0+ (auxiliary) execution units, sharing AXBS-Lite crossbar interconnect and eDMA controller. Its clock system integrates SPLL (up to 112 MHz), FIRC (48 MHz), SIRC (8 MHz), and LPO (128 kHz), with configurable power modes (HSRUN, RUN, STOP, VLPR, VLPS) managed by PMC.
Memory subsystem includes 2 MB program flash with ECC, 64 KB FlexNVM (ECC + EEPROM emulation), 256 KB SRAM with ECC, 4 KB FlexRAM, and 4 KB code cache. Safety features include System MPU (crossbar-level memory protection), CRC module, WDOG/EWM, and ISO 26262-compliant design up to ASIL-B.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K146UAT0VLHR | Same 176-pin LQFP package, but 1 MB flash, 192 KB SRAM, no Ethernet or SAI; V-grade (-40 °C to +105 °C). | Lacks Ethernet/SAI; suitable for non-gateway body control where cost and lower temp range are prioritized. | Select when Ethernet connectivity and extended temperature are unnecessary - reduces BOM cost while retaining CAN-FD, CSEc, and ASIL-B support. |
| S32K148UAT0WLHR | Identical feature set but W-grade (-40 °C to +150 °C); requires 3.13–5.5 V supply (vs. 2.7–5.5 V for FS32K148UAT0VMHR). | Targeted at under-hood powertrain applications exceeding 125 °C ambient (e.g., turbocharger control). | Choose only if ambient exceeds +125 °C; otherwise, FS32K148UAT0VMHR offers broader voltage range and lower system-level supply design complexity. |
Compared with FS32K148UAT0VLHR and FS32K148UAT0WLHR, the FS32K148UAT0VMHR uniquely balances extended temperature capability (+125 °C), full Ethernet/SAI integration, and wide-input-voltage operation (2.7 V min), making it optimal for gateways and high-integration body controllers where supply robustness and protocol flexibility are critical.

FAQ
What is the maximum operating frequency of the FS32K148UAT0VMHR, and under what conditions?
The FS32K148UAT0VMHR achieves 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode requires VDD ≥ 2.97 V when PLL is active; RUN mode supports full functionality including CSEc cryptographic operations and EEPROM emulation. Operation above 80 MHz disables CSEc and FlexNVM writes per datasheet Section 1.1 and Note 1.
Does the FS32K148UAT0VMHR support CAN-FD, and how many instances are available?
Yes, the FS32K148UAT0VMHR integrates three FlexCAN modules, all supporting CAN-FD (ISO 11898-1). Each module is independently configurable for classic CAN or CAN-FD frames, with bit rates up to 5 Mbps in FD mode. The device's 176-pin LQFP package provides dedicated CAN_TX/CAN_RX pins for all three channels.
What memory protection mechanisms does the FS32K148UAT0VMHR implement for functional safety?
The FS32K148UAT0VMHR implements a System Memory Protection Unit (MPU) at the crossbar switch level - not the Arm core MPU - enabling independent access rights for CPU, DMA, and Ethernet masters to protected memory regions. Combined with ECC on flash and SRAM, this satisfies ASIL-B requirements per ISO 26262 for memory integrity and unauthorized access prevention.
Can the FS32K148UAT0VMHR operate from a 3.3 V supply, and what are the implications?
Yes, the FS32K148UAT0VMHR operates across 2.7–5.5 V, including standard 3.3 V systems. At 3.3 V, HSRUN mode is supported up to 112 MHz (subject to VDD ≥ 2.97 V), and all peripherals - including Ethernet PHY interface and ADC references - remain fully functional. No derating or feature loss occurs at 3.3 V.
What debug and trace capabilities are built into the FS32K148UAT0VMHR?
The FS32K148UAT0VMHR includes Serial Wire JTAG Debug Port (SWJ-DP) with Debug Watchpoint and Trace (DWT), Instrumentation Trace Macrocell (ITM), Test Port Interface Unit (TPIU), and Flash Patch and Breakpoint (FPB) unit. It supports real-time SWO trace output, MTB (1 KB), and full IDE integration with NXP S32DS, IAR, GHS, and Arm Keil toolchains.
