Product details
Overview
FS32K142UAT0VLHR from NXP Semiconductors is an automotive-grade 32-bit Arm Cortex-M4F microcontroller designed for real-time control in safety-critical ECUs. It operates at up to 112 MHz (HSRUN mode), features 256 KB flash with ECC, 256 KB SRAM with ECC, and supports -40 °C to +105 °C ambient operation in a 100-pin LQFP package. It integrates FlexCAN with optional CAN-FD, dual 12-bit ADCs (up to 32 channels), and CSEc cryptographic engine.
For engineers reviewing the FS32K142UAT0VLHR datasheet, FS32K142UAT0VLHR pinout, FS32K142UAT0VLHR application, or FS32K142UAT0VLHR equivalent, key selection considerations include HSRUN/RUN mode switching constraints for CSEc/EEPROM operations, 100-pin LQFP pin compatibility across S32K14x family members, CAN-FD readiness, and ASIL-B capable memory protection architecture.
Technical Context
The FS32K142UAT0VLHR implements a dual-core-capable architecture with Arm Cortex-M4F core (Armv7, Thumb-2 ISA) and integrated DSP/FPU, supporting deterministic real-time execution up to 112 MHz in HSRUN mode - though CSEc security operations and EEPROM emulation require downshifting to 80 MHz RUN mode. Its AXBS-Lite crossbar switch enables concurrent access by CPU, DMA, and peripherals while enforcing memory isolation via NXP's system MPU.
Peripherals are organized into low-power domains: three LPUART/LIN modules, two LPI2C, three LPSPI, two FlexCAN controllers (one with CAN-FD support), eight FlexTimer modules (64 total PWM/IC/OC channels), and dual 12-bit ADCs with 1 Msps sampling rate. All analog and digital I/Os comply with automotive voltage ranges (2.7–5.5 V) and thermal specs (-40 °C to +105 °C).

FAQ
What is the maximum operating frequency of the FS32K142UAT0VLHR, and under what conditions?
The FS32K142UAT0VLHR achieves up to 112 MHz in HSRUN mode, but only when not executing CSEc cryptographic operations or FlexNVM EEPROM emulation - those functions require switching to 80 MHz RUN mode. This constraint is enforced in hardware to prevent error flag generation and ensure reliable flash write/erase cycles.
Does the FS32K142UAT0VLHR support CAN-FD, and how many CAN interfaces does it include?
The FS32K142UAT0VLHR includes two FlexCAN modules, with one supporting CAN-FD (ISO 11898-1) at data rates up to 5 Mbps. The second FlexCAN operates in classical CAN mode. Both support message filtering, FIFO buffering, and loopback self-test - essential for automotive network diagnostics and redundancy.
What safety certifications or functional safety features are implemented in the FS32K142UAT0VLHR?
The FS32K142UAT0VLHR incorporates System MPU for memory region protection, ECC on flash and SRAM, CRC module, dual watchdogs (WDOG and EWM), and lockstep-capable peripherals - collectively enabling ASIL-B compliance per ISO 26262. Its safety manual and FMEDA reports are available from NXP for integration into safety case documentation.
Can the FS32K142UAT0VLHR execute code from external memory, and which interface is used?
Yes, the FS32K142UAT0VLHR supports external memory execution via its QuadSPI interface with HyperBus™ protocol compatibility. This allows booting from and running code directly out of external NOR flash, extending effective program memory beyond the on-chip 256 KB flash - particularly useful for secure OTA update staging.
What is the purpose of the FlexIO module in the FS32K142UAT0VLHR, and which protocols can it emulate?
The FlexIO module in the FS32K142UAT0VLHR is a programmable logic block that emulates serial protocols including UART, I²C, SPI, I²S, LIN, and PWM - using only GPIO pins. It reduces BOM cost and board space by eliminating external protocol translators, especially valuable in resource-constrained ECUs like seat controllers or HVAC nodes.
