FAQ
What is the maximum CAN FD data rate supported by CYT3BB5CEBQ0AEEGST?
CYT3BB5CEBQ0AEEGST supports CAN FD up to 8 Mbps, compliant with ISO 11898-1:2015 and certified to ISO 16845:2015. The actual achievable rate depends on physical layer topology and transceiver selection-not internal controller limitation. All eight CAN FD channels share this capability and operate independently with configurable bit timing registers.
Does CYT3BB5CEBQ0AEEGST support secure boot with public-key verification?
Yes. CYT3BB5CEBQ0AEEGST implements fast secure boot using digital signature verification with RSA or ECC keys stored in eFuse or protected flash. The HSM validates signatures before loading application code into TCM, ensuring only authenticated firmware executes. Root-of-trust is established in ROM bootloader and reinforced by eSHE-compliant key management.
How many independent ADC instances does CYT3BB5CEBQ0AEEGST provide, and what is their resolution?
CYT3BB5CEBQ0AEEGST integrates three independent 12-bit SAR ADCs (ADC0–ADC2), each supporting up to 1 Msps sampling rate. ADC0 and ADC1 each handle 32 logical channels with dedicated sequencers; ADC2 supports 8 logical channels. All support synchronized sampling for motor control and internal references including bandgap and temperature diode.
Is the Ethernet MAC in CYT3BB5CEBQ0AEEGST capable of IEEE-1588 Precision Time Protocol?
Yes. The integrated 10/100 Mbps Ethernet MAC fully supports IEEE-1588-2008 (PTPv2) with hardware timestamping for transmit and receive frames. It operates in both one-step and two-step clock correction modes and interfaces directly with MII or RMII PHYs-enabling time-synchronized communication essential for automotive audio/video bridging and sensor fusion networks.
