FAQ
What is the maximum CAN FD data rate supported by CY9BF506RBPMC-G-UNE2?
The device supports CAN FD bit rates up to 5 Mbps in data phase, compliant with ISO 11898-1:2015. Its CAN FD controllers include programmable bit timing registers, automatic retransmission, and flexible data payload configuration up to 64 bytes per frame. This enables high-bandwidth diagnostics and ECU reprogramming in modern vehicle networks.
Does CY9BF506RBPMC-G-UNE2 include hardware support for secure boot?
Yes. It integrates a dedicated hardware crypto engine supporting AES-128/256, SHA-256, and a true random number generator (TRNG). These accelerate signature verification during boot, enabling sub-200 ms secure boot times. The ROM bootloader validates signed firmware images before execution, with keys stored in protected OTP memory.
Is dual-bank flash swap functionality available without external supervision?
Yes. The MCU implements an autonomous flash swap mechanism triggered via dedicated system control registers. Once initiated, the hardware handles bank switching, address remapping, and status flag updates without CPU intervention-ensuring atomicity even during power loss events within specified voltage thresholds.
