FAQ

What is the maximum operating frequency of the FS32K144UFT0VLLR?

The FS32K144UFT0VLLR 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 80 MHz when executing CSEc security functions or EEPROM writes to prevent error flag assertion.

Does the FS32K144UFT0VLLR support CAN-FD?

Yes, the FS32K144UFT0VLLR integrates three FlexCAN modules that support CAN-FD per ISO 11898-1:2015, enabling data rates up to 5 Mbps in the data phase. CAN-FD functionality is enabled by default and does not require external components - only a compliant transceiver is needed on the board.

What package type is used for the FS32K144UFT0VLLR?

The FS32K144UFT0VLLR uses a 144-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible with other S32K14x devices in the same pin count, allowing reuse of PCB layouts across performance tiers within the family.

How does the CSEc security engine function in the FS32K144UFT0VLLR?

The CSEc engine in the FS32K144UFT0VLLR implements SHE-compliant cryptographic operations including AES-128/256 encryption/decryption, SHA-256 hashing, and true random number generation. It operates independently of the main CPU and enforces secure boot, firmware authentication, and key provisioning - all verified during reset sequence before application code execution begins.

Is the FS32K144UFT0VLLR qualified for automotive applications?

Yes, the FS32K144UFT0VLLR is AEC-Q100 Grade 2 qualified (-40 °C to +105 °C), ISO 26262 ASIL-B compliant, and designed to meet stringent automotive reliability, EMC, and functional safety requirements. Its ECC memory, system MPU, and dual watchdog architecture support safety-critical deployment in body, chassis, and gateway ECUs.
