FAQ

What is the maximum operating frequency of FX32K142HAT0MLFT, and under what conditions?

FX32K142HAT0MLFT achieves up to 112 MHz in HSRUN mode, but only when operating within its specified voltage (2.7–5.5 V) and temperature (-40 °C to +125 °C) ranges. Critical operations such as CSEc cryptographic execution or EEPROM writes require switching to RUN mode (80 MHz); attempting them in HSRUN mode triggers error flags.

Does FX32K142HAT0MLFT support CAN-FD, and how is it implemented?

FX32K142HAT0MLFT includes one FlexCAN module that supports CAN-FD when enabled via configuration registers and paired with a CAN-FD–capable transceiver. The module complies with ISO 11898-1:2015 and supports data rates up to 5 Mbps in FD mode, with flexible bit timing and payload length up to 64 bytes.

How does the memory protection architecture work in FX32K142HAT0MLFT?

FX32K142HAT0MLFT uses NXP's System MPU - a crossbar-switch–level enforcement mechanism - to assign access rights (read/write/execute) per memory region for each master (CPU, DMA, Ethernet). Unlike Arm Core MPU, it protects all bus masters, enabling ASIL-B–compliant partitioning without relying solely on core-initiated checks.

What are the supported low-power modes for FX32K142HAT0MLFT, and which peripherals remain active in VLPS?

FX32K142HAT0MLFT supports HSRUN, RUN, STOP, VLPR, and VLPS modes. In VLPS, the core and most clocks halt, but LPTMR, LPIT, RTC, and selected LPI2C/LPUART instances remain operational with wakeup capability. FlexCAN and ADC are disabled unless configured for low-power trigger sources.

Is FX32K142HAT0MLFT pin-compatible with other S32K1xx devices in the same package?

Yes - all S32K1xx devices sharing the same package (e.g., 64-pin LQFP) are pin-to-pin compatible per NXP's documentation. FX32K142HAT0MLFT shares identical pinout with S32K144HAT0MLFT and S32K146HAT0MLFT in 64-pin LQFP, enabling hardware reuse across performance tiers.
