Product details
Overview
FS32K142UAT0VLLT from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller with 256 KB flash, 64 KB SRAM, and integrated CSEc security engine. It operates at up to 112 MHz in HSRUN mode (−40 °C to +105 °C), supports FlexCAN with CAN-FD, dual 12-bit ADCs (1 Msps), and runs on 2.7–5.5 V supply. It is used in body control modules and gateway ECUs requiring ASIL-B functional safety compliance.
For engineers reviewing the FS32K142UAT0VLLT datasheet, FS32K142UAT0VLLT pinout, FS32K142UAT0VLLT application, or FS32K142UAT0VLLT equivalent, this page delivers verified core architecture details, validated power mode behavior, confirmed peripheral integration (LPUART/LPSPI/LPI2C/FlexIO), and precise package mapping to 100-pin LQFP - all aligned with NXP's S32K1xx Rev. 15 specification.
Technical Context
The FS32K142UAT0VLLT implements a dual-core capable architecture with Arm Cortex-M4F CPU (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support via software configuration. Its memory subsystem includes ECC-protected 256 KB program flash, 64 KB SRAM, and 4 KB FlexRAM usable for EEPROM emulation or SRAM expansion.
Power management is governed by the PMC with five defined modes (HSRUN, RUN, STOP, VLPR, VLPS); critical operations like CSEc cryptographic execution or EEPROM write/erase are explicitly restricted to RUN mode (80 MHz) - not permitted in HSRUN - per NXP's documented hardware enforcement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FS32K144UAT0VLLT | 512 KB flash, 128 KB SRAM, 3× FlexCAN, 3× LPUART - larger memory and expanded peripheral count. | Preferred for gateway ECUs requiring additional CAN channels and larger OTA update partitioning space. | Select when >256 KB flash or third FlexCAN channel is required; otherwise FS32K142UAT0VLLT offers optimal cost/performance balance. |
| FS32K142MT0VLLT | Same core and peripherals but rated for −40 °C to +125 °C ambient (M-grade); uses 80 MHz RUN-only operation. | Suitable for under-hood applications where extended temperature range is mandatory but HSRUN mode is unnecessary. | Choose for engine bay placement where 112 MHz operation is not needed; FS32K142UAT0VLLT remains preferred for cabin/gateway use with performance headroom. |
Compared with FS32K144UAT0VLLT and FS32K142MT0VLLT, the FS32K142UAT0VLLT uniquely balances 112 MHz HSRUN performance, V-grade temperature qualification, and minimal BOM cost - making it the default choice for mid-tier automotive control units where flash scalability and extreme ambient tolerance are secondary to real-time throughput and security.

FAQ
What is the maximum operating frequency of the FS32K142UAT0VLLT and under what conditions?
The FS32K142UAT0VLLT achieves up to 112 MHz in HSRUN mode, but only within the −40 °C to +105 °C ambient temperature range and with supply voltage ≥2.7 V. Operation above 80 MHz requires VDD ≥2.97 V when PLL is engaged. The device automatically throttles to 80 MHz RUN mode for CSEc execution or EEPROM writes, as mandated by hardware-enforced safety logic.
Does the FS32K142UAT0VLLT support CAN-FD, and how many instances are available?
Yes, the FS32K142UAT0VLLT integrates two independent FlexCAN modules, both supporting CAN-FD per ISO 11898-1 with data rates up to 5 Mbps. Each module includes dedicated message RAM, acceptance filtering, and loopback/self-test modes - fully accessible in the 100-pin LQFP package without pin conflicts.
What security features does the FS32K142UAT0VLLT provide, and are they enabled by default?
The FS32K142UAT0VLLT includes the Cryptographic Services Engine (CSEc) with AES-128, SHA-256, RNG, and secure boot key storage in OTP. CSEc is factory-configured in disabled state; activation requires provisioning via NXP's Secure Provisioning Tool and a valid certificate chain. No security functions operate in HSRUN mode - all CSEc operations require explicit switch to RUN mode (80 MHz).
Is the FS32K142UAT0VLLT pin-compatible with other S32K1xx devices in the same package?
Yes, all S32K1xx devices sharing the 100-pin LQFP (LL) package - including FS32K142UAT0VLLT, FS32K144UAT0VLLT, and FS32K146UAT0VLLT - are fully pin-to-pin compatible per NXP's documentation. Peripheral availability depends on silicon configuration, not pinout; unused signals remain in high-impedance state and do not affect board layout.
What development tools and IDEs are officially supported for the FS32K142UAT0VLLT?
NXP officially supports FS32K142UAT0VLLT with S32 Design Studio (based on Eclipse and GCC), IAR Embedded Workbench, Green Hills MULTI, Arm Keil MDK, and Lauterbach TRACE32. SDKs include AUTOSAR 4.3-compliant MCAL drivers, FreeRTOS BSP, and S32K1xx-specific HAL libraries - all validated against the FS32K142UAT0VLLT silicon revision.
