This frequency is validated across the full -40 °C to 125 °C ambient temperature range and 2.97 V to 5.5 V supply voltage, enabling deterministic real-time execution in automotive control loops. The S32K312NHT0VPAST does not support the 160 MHz or 240 MHz variants found in higher-tier S32K3xx devices like the S32K324 or S32K328.
Does the S32K312NHT0VPAST support CAN FD, and how many channels are available?
Yes, the S32K312NHT0VPAST supports CAN FD on all FlexCAN modules. It includes up to 12 FlexCAN modules, each capable of CAN FD operation at data rates up to 5 Mbps. This capability is confirmed in the S32K3xx Data Sheet Rev. 14 and applies directly to the S32K312NHT0VPAST variant, enabling high-throughput communication in modern vehicle networks.
What package options are available for the S32K312NHT0VPAST?
The S32K312NHT0VPAST is offered in the MAPBGA289 package (13 mm × 13 mm, 0.8 mm pitch, exposed pad). This package is explicitly listed in the S32K3xx Data Sheet for the S32K312 variant and supports thermal management in automotive under-hood applications. Other packages like MAPBGA437 or HDQFP172 apply to different S32K3xx members but not to the S32K312NHT0VPAST.
Is the S32K312NHT0VPAST qualified for ASIL-B functional safety compliance?
Yes, the S32K312NHT0VPAST is certified to ASIL-B per ISO 26262. Its safety features include ECC on all memories, hardware watchdog timers (SWT), centralized fault collection unit (FCCU), memory BIST, clock/voltage monitors, and error-detecting CRC modules - all documented in the S32K3xx functional safety manual and validated for ASIL-B use cases such as body control and EPS.
Does the S32K312NHT0VPAST include hardware security acceleration?
Yes, the S32K312NHT0VPAST integrates the HSE_B (Hardware Security Engine) supporting AES-256, RSA-4096, and ECC-521 cryptographic acceleration. Firmware is upgradable and includes side-channel physical protections aligned with EVITA Full security goals.
