Product details
Overview
FS32K142HAT0MLHR from NXP Semiconductors is an automotive-grade 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 +125 °C ambient operation. Its integrated CSEc security engine, FlexCAN with CAN-FD support, and dual 12-bit ADCs make it suitable for body control modules and gateway applications.
For engineers reviewing the FS32K142HAT0MLHR datasheet, FS32K142HAT0MLHR pinout, FS32K142HAT0MLHR application, or FS32K142HAT0MLHR equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain readiness - all aligned to the S32K142 variant's documented specifications and ordering constraints.
Technical Context
The FS32K142HAT0MLHR implements a dual-core capable architecture with Arm Cortex-M4F core (112 MHz HSRUN / 80 MHz RUN) and optional M0+ co-processor support in family variants - though this specific part uses M4F only. It integrates SPLL clock synthesis, FIRC/SIRC/LPO oscillators, and configurable power modes (HSRUN, RUN, STOP, VLPR, VLPS) with PMC-controlled voltage scaling.
Its memory subsystem includes 256 KB program flash with ECC, 256 KB SRAM with ECC, 4 KB FlexRAM for EEPROM emulation, and QuadSPI with HyperBus™ support. Safety features include System MPU (crossbar-level), CRC module, WDOG/EWM, and CSEc cryptographic engine - with CSEc operations requiring transition from HSRUN to RUN mode (80 MHz).

FAQ
What is the maximum operating frequency of the FS32K142HAT0MLHR?
The FS32K142HAT0MLHR operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. The 112 MHz frequency is supported only within the -40 °C to +105 °C ambient range; operation above 105 °C requires switching to RUN mode at 80 MHz. This dual-frequency capability allows dynamic performance scaling based on thermal and safety constraints.
Does the FS32K142HAT0MLHR support CAN-FD?
Yes, the FS32K142HAT0MLHR includes one FlexCAN module that supports CAN-FD protocol with data rates up to 5 Mbps. CAN-FD functionality is enabled via configuration registers and requires external transceiver compliance with ISO 11898-1:2015. The module supports both classic CAN and CAN-FD frames on the same bus.
What package type is used for the FS32K142HAT0MLHR?
The FS32K142HAT0MLHR uses a 64-pin LQFP package with 0.5 mm pitch and an exposed thermal pad. It is RoHS-compliant and pin-compatible with other S32K14x variants in the same footprint, enabling scalable design reuse across performance tiers within the family.
Can the FS32K142HAT0MLHR execute CSEc security operations at 112 MHz?
No. CSEc (Cryptographic Services Engine) operations - including AES encryption, SHA hashing, and key generation - are prohibited in HSRUN mode (112 MHz). The FS32K142HAT0MLHR must transition to RUN mode (80 MHz) before initiating any CSEc command; attempting execution in HSRUN triggers error flags and halts the operation.
How much on-chip SRAM does the FS32K142HAT0MLHR provide?
The FS32K142HAT0MLHR provides 256 KB of on-chip SRAM with built-in Error-Correcting Code (ECC). This memory is partitioned into main SRAM banks and includes dedicated sections for stack, heap, and safety-critical data buffers - all protected against single-bit errors and detectable double-bit faults.
