FAQ
What is the maximum operating frequency of the PS32K144UAT0VLHA?
The PS32K144UAT0VLHA achieves up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. Operation at 112 MHz requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C. The device automatically throttles to RUN mode during CSEc execution or EEPROM writes to prevent error flag assertion.
Does the PS32K144UAT0VLHA support CAN-FD?
Yes, the PS32K144UAT0VLHA includes three FlexCAN modules, each configurable for CAN-FD operation per ISO 11898-1:2015. CAN-FD frame support requires appropriate transceiver pairing and software stack implementation using NXP's S32DS SDK or AUTOSAR CAN IF.
What safety certifications apply to the PS32K144UAT0VLHA?
The PS32K144UAT0VLHA is AEC-Q100 Grade 2 qualified (-40 °C to +105 °C), supports ISO 26262 ASIL-B development processes, and integrates hardware safety mechanisms including ECC on memories, System MPU, CRC unit, WDOG/EWM, and lockstep-capable peripherals.
How much SRAM does the PS32K144UAT0VLHA provide?
The PS32K144UAT0VLHA includes 256 KB of on-chip SRAM with Error-Correcting Code (ECC) protection. This memory is partitioned into main SRAM and FlexRAM (4 KB), the latter configurable as additional SRAM or EEPROM emulation space.
Is the PS32K144UAT0VLHA pin-compatible with other S32K1xx devices?
Yes - all S32K1xx devices sharing the 144-pin LQFP package (e.g., PS32K144UAT0VLHR, PS32K146UAT0VLHA) are pin-to-pin compatible. Peripheral availability depends on pin multiplexing configuration, and full feature mapping is validated in the S32K1xx Reference Manual IO Signal Description sheet.
