Product details
Overview
FS32K148UAT0VLUT 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, CSEc security engine, and triple FlexCAN with CAN-FD support - deployed in vehicle body control modules requiring ASIL-B functional safety compliance.
For engineers reviewing the FS32K148UAT0VLUT datasheet, FS32K148UAT0VLUT pinout, FS32K148UAT0VLUT application, or FS32K148UAT0VLUT equivalent, key selection considerations include its -40 °C to 105 °C ambient rating (V-grade), 100-pin LQFP package, dual 12-bit ADCs (32-channel total), Ethernet MAC with IEEE 1588, and mandatory RUN-mode (80 MHz) execution for CSEc/EEPROM operations.
Technical Context
The FS32K148UAT0VLUT implements a dual-core architecture with Arm Cortex-M4F as primary core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor, integrated System MPU for crossbar-level memory protection, and dedicated SPLL clock subsystem supporting up to 112 MHz system frequency. Its power management includes five distinct modes (HSRUN, RUN, STOP, VLPR, VLPS), with strict mode-dependent restrictions on CSEc and EEPROM access.
Peripherals are routed via AXBS-Lite crossbar switch with eDMA support (16 channels, 63 request sources), enabling concurrent high-bandwidth transfers across FlexCAN, LPUART, LPSPI, and QuadSPI interfaces. The device integrates hardware-accelerated cryptographic services (SHE-compliant CSEc), 32-bit RTC, eight FlexTimer modules (64 PWM/IC/OC channels), and two independent 12-bit SAR ADCs each capable of 1 Msps sampling.

FAQ
What is the maximum operating frequency of the FS32K148UAT0VLUT and under what conditions?
The FS32K148UAT0VLUT achieves 112 MHz in HSRUN mode, but this requires VDD ≥ 2.97 V when the SPLL is active. At lower voltages (≥2.7 V), it operates at 80 MHz in RUN mode. The device automatically transitions between modes based on voltage and software configuration, and critical functions like CSEc and EEPROM writes must execute in RUN mode only.
Does the FS32K148UAT0VLUT support CAN-FD, and how many interfaces are available?
Yes, the FS32K148UAT0VLUT integrates three FlexCAN modules, all supporting CAN-FD (ISO 11898-1) with data rates up to 5 Mbps. Each module includes dedicated message RAM, acceptance filtering, and loopback/self-test capabilities - enabling robust multi-domain communication in vehicle networks without external protocol translators.
What safety features does the FS32K148UAT0VLUT include for ASIL-B compliance?
The FS32K148UAT0VLUT includes ECC on 2 MB flash and 256 KB SRAM, System MPU for crossbar-level memory protection, dual watchdogs (WDOG and EWM), CRC acceleration unit, and lockstep-capable peripherals. These features collectively satisfy ISO 26262 ASIL-B requirements for automotive ECUs, validated through NXP's certified safety documentation package.
Can the FS32K148UAT0VLUT execute cryptographic operations at full speed?
No - the Cryptographic Services Engine (CSEc) in the FS32K148UAT0VLUT cannot operate in HSRUN mode (112 MHz). Secure boot, key provisioning, and AES/SHA operations require switching to RUN mode (80 MHz), as confirmed in the datasheet's power mode notes and feature comparison tables. This is a hard architectural constraint, not a configuration option.
What package type and pin count does the FS32K148UAT0VLUT use?
The FS32K148UAT0VLUT uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. It is pin-compatible with other S32K14x devices in the same package variant, enabling scalable design reuse across memory and peripheral configurations without PCB redesign.
