FAQ
What is the maximum CAN FD data rate supported by CY9BF404NAPMC-G-UNE2?
The CY9BF404NAPMC-G-UNE2 supports CAN FD bit rates up to 5 Mbps in the data phase, compliant with ISO 11898-1:2015. Its CAN FD controller includes programmable bit timing registers and automatic retransmission on error frames, enabling robust communication in electrically noisy automotive environments.
Does CY9BF404NAPMC-G-UNE2 include hardware support for secure boot?
Yes. The device implements ROM-based secure boot with immutable root-of-trust, verifying signed firmware images using ECDSA-P256 before execution. Public keys are stored in one-time-programmable (OTP) memory, and signature verification occurs within the hardware crypto engine to prevent side-channel leakage.
Can CY9BF404NAPMC-G-UNE2 operate in USB host mode?
Yes. The integrated USB 2.0 Full-Speed PHY supports device, host, and OTG modes. In host mode, it drives standard USB peripherals such as diagnostic tools or flash drives, with built-in VBUS detection and current limiting per USB specification.
What is the Flash erase/write endurance specification?
The 1 MB dual-bank Flash is rated for 100,000 erase/write cycles per sector, with data retention guaranteed for 20 years at 105°C. Each bank supports independent erase operations, allowing background writes during active code execution in the other bank.
