FAQ
What is the maximum operating temperature range for TC366DP64F300SAALXUMA1?
The TC366DP64F300SAALXUMA1 is qualified for operation from −40 °C to 125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating applies to the full functional specification including flash programming, Ethernet MAC operation, and lockstep CPU execution under voltage and thermal stress conditions.
Does TC366DP64F300SAALXUMA1 support hardware virtualization or hypervisor features?
No, the TC366DP64F300SAALXUMA1 does not implement hardware virtualization extensions. It relies on partitioned memory protection units (MPUs), core isolation, and SMU-managed resource access control to achieve ASIL-D separation-consistent with AUTOSAR Classic and ISO 26262 Part 6 tool qualification requirements.
Can the integrated Ethernet MAC operate in full-duplex 100BASE-TX mode without an external PHY?
No. The TC366DP64F300SAALXUMA1 includes only the Media Access Control (MAC) layer. A compliant 10/100 Ethernet PHY IC (e.g., Infineon TLF35584 or compatible IEEE 802.3u device) must be used externally to drive the physical medium and handle MDI signaling.
Is the 6 MB flash memory field-programmable and protected against unauthorized access?
Yes, the 6 MB embedded flash supports in-system programming via JTAG or DAP interface, with configurable write-protection regions, secure boot authentication using SHA-256 and RSA-3072, and debug access restriction via unique device identifier and fuse-controlled security bits.
