FAQ
What is the maximum operating frequency of the FS32K142HAT0MLHT and under what conditions?
The FS32K142HAT0MLHT operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. HSRUN mode requires VDD ≥ 2.7 V and ambient temperature ≤ +105 °C; RUN mode supports full -40 °C to +125 °C operation. The device automatically throttles to 80 MHz when executing CSEc security operations or FlexNVM writes/erases to prevent error flag assertion.
Does the FS32K142HAT0MLHT support CAN-FD, and how many interfaces are available?
Yes, the FS32K142HAT0MLHT integrates three FlexCAN modules, each supporting CAN-FD (ISO 11898-1) with data rates up to 5 Mbps. All three interfaces are fully functional in the 100-pin LQFP package and support programmable bit timing, loopback testing, and error confinement - essential for automotive domain controllers requiring redundant communication paths.
What memory resources does the FS32K142HAT0MLHT provide, and are they ECC-protected?
The FS32K142HAT0MLHT includes 512 KB of program flash memory, 64 KB of FlexNVM (for EEPROM emulation), and 256 KB of SRAM - all protected by Error-Correcting Code (ECC). Additionally, it provides 4 KB of FlexRAM usable as SRAM or EEPROM emulation, and a 4 KB instruction cache to reduce memory access latency during real-time execution.
How does the CSEc security engine in the FS32K142HAT0MLHT support automotive cybersecurity requirements?
The CSEc engine in the FS32K142HAT0MLHT implements SHE-compliant cryptographic functions including AES-128 encryption/decryption, SHA-256 hashing, true random number generation, and secure boot verification. It enables secure OTA firmware updates, key provisioning, and runtime attestation - all without external security ICs, meeting UNECE R155 and ISO/SAE 21434 requirements.
What is the thermal rating of the FS32K142HAT0MLHT, and how does it affect mode selection?
The FS32K142HAT0MLHT is M-grade rated for -40 °C to +125 °C ambient operation. In HSRUN mode (112 MHz), junction temperature must remain ≤135 °C, limiting sustained operation to ≤+105 °C ambient under typical board conditions. For full -40 °C to +125 °C operation, the device must run in RUN mode (80 MHz), where junction limit is 135 °C and thermal derating is managed via PMC-controlled power gating.
Is the FS32K142HAT0MLHT pin-compatible with other S32K1xx devices, and which packages share identical pinouts?
Yes, all S32K14x devices sharing the same package type are pin-to-pin compatible. The FS32K142HAT0MLHT in 100-pin LQFP shares identical pinout with S32K144HAT0MLHT, S32K146HAT0MLHT, and S32K148HAT0MLHT in the same package - enabling hardware reuse across performance tiers while maintaining software compatibility through NXP's S32 SDK.
