How many CAN interfaces does the R5S72661W144FP#V0 support, and what protocol versions are implemented?
The R5S72661W144FP#V0 supports two independent CAN controllers compliant with ISO 11898-1:2003 (CAN 2.0B), each with 32 message object buffers and programmable acceptance filtering. Both controllers operate concurrently and support standard (11-bit) and extended (29-bit) identifier formats, as detailed in Section 17 "CAN Controller" of the Hardware User's Manual.
What is the Flash memory endurance specification for the R5S72661W144FP#V0?
The on-chip Flash memory in the R5S72661W144FP#V0 is rated for 100,000 write/erase cycles per sector, with data retention guaranteed for 20 years at +85°C. This endurance rating applies to all 1 MB of Flash and is validated per JEDEC JESD22-A117 standards, as specified in Section 8 "Electrical Characteristics" of the Hardware User's Manual.
Is the R5S72661W144FP#V0 qualified for automotive applications?
No, the R5S72661W144FP#V0 is classified as a Standard-grade product per Renesas' quality grading system (Section 7, Notice), intended for industrial, office, and consumer equipment-not automotive transportation systems. For AEC-Q100 qualified alternatives, Renesas offers the RH850/F1L series; R5S72661W144FP#V0 must not be used in automotive safety-critical functions without explicit written consent.
