FAQ
What is the maximum operating temperature range for CY8C4149AZAS565XQLA1?
This part is rated Grade-S per AEC-Q100, supporting continuous operation from –40°C to +105°C ambient temperature. It is qualified for under-hood and cabin-mounted automotive applications where thermal stress exceeds consumer-grade limits, and includes on-die temperature sensor calibrated against the 12-bit SAR ADC for closed-loop thermal management.
Does CY8C4149AZAS565XQLA1 support hardware-based secure boot?
Yes - the integrated cryptography accelerator provides AES-128/256 decryption, SHA-256 hashing, and TRNG generation required for authenticated secure boot. The ROM bootloader validates signature and hash of user firmware before execution, and supports key revocation via protected flash regions managed by ModusToolbox™ Secure Boot Manager.
Can the CAPSENSE™ block operate during Deep Sleep mode?
Yes - the Multi-Sense Converter (MSC) remains fully functional in Deep Sleep mode with only 2.5 µA system current. It supports wake-on-touch with hardware-accelerated baseline tracking and noise filtering, and maintains >5:1 SNR without CPU intervention, enabling instant UI responsiveness after sleep.
How many CAN FD channels does CY8C4149AZAS565XQLA1 support?
CY8C4149AZAS565XQLA1 includes one dedicated CAN FD controller block supporting data rates up to 5 Mbps, with hardware message filtering, FIFO buffering, and error counters.
