Does the UPD70F3573GKA2-GAK-E2-AX support CAN FD?
No, the UPD70F3573GKA2-GAK-E2-AX implements CAN 2.0B only, with bit rates up to 1 Mbps. It does not include CAN FD protocol support, frame formatting, or enhanced data payload handling. For CAN FD requirements, consider Renesas' RX72M or RA6T2 families.
Is the UPD70F3573GKA2-GAK-E2-AX pin-compatible with other V850E2/Fx4-L devices?
Yes, the UPD70F3573GKA2-GAK-E2-AX shares identical LQFP-100 pinout and peripheral mapping with µPD70F3572, µPD70F3574, and µPD70F3575 in the same family. Pin functions, power domains, and reset behavior are fully aligned per Renesas' V850E2/Fx4-L hardware manual.
What debug interface does the UPD70F3573GKA2-GAK-E2-AX use?
The UPD70F3573GKA2-GAK-E2-AX uses Renesas' on-chip debug (OCD) interface compliant with IEEE 1149.1 (JTAG), supporting full-speed debugging, flash programming, and real-time trace via dedicated TCK/TMS/TDI/TDO pins. It requires the E2 emulator or compatible JTAG probe.
Does the UPD70F3573GKA2-GAK-E2-AX include hardware encryption acceleration?
No, the UPD70F3573GKA2-GAK-E2-AX does not integrate dedicated AES, SHA, or TRNG hardware accelerators. Security functions such as secure boot or firmware signature verification must be implemented in software using the V850E2 core's general-purpose registers and memory protection unit (MPU).
