FAQ

What automotive safety standard does R7F7016934AFP-C#BA1 comply with?

R7F7016934AFP-C#BA1 is designed to meet ISO 26262 ASIL-D requirements at the hardware level, with integrated lockstep CPU cores, memory ECC/parity, hardware safety monitor (HSM), and diagnostic coverage validated per ISO 26262-5 Annex D. The device supports FMEDA reports and safety manuals provided by Renesas for system-level ASIL-D integration. R7F7016934AFP-C#BA1 enables end-to-end safety case development for engine control, braking, and steering applications.

Does R7F7016934AFP-C#BA1 support Ethernet AVB, and what PHY interface is used?

Yes, R7F7016934AFP-C#BA1 integrates a 100BASE-T1 Ethernet AVB controller compliant with IEEE 802.1Qav and 802.1AS standards. It uses a reduced-pin MII interface (RMII variant) with dedicated ETH_MDIO, ETH_MDC, ETH_TX_CLK, ETH_RX_CLK, and differential TX/RX pairs. External 100BASE-T1 PHY (e.g., Broadcom BCM89881) is required, and the MCU handles time synchronization, stream reservation, and credit-based shaper logic in hardware. R7F7016934AFP-C#BA1 supports precise timestamping with <100ns resolution.

What is the maximum CAN FD bit rate supported by R7F7016934AFP-C#BA1?

R7F7016934AFP-C#BA1 supports CAN FD data rates up to 5 Mbps on all six integrated CAN FD channels. Each channel features independent bit timing registers, automatic protocol switching between Classical CAN and CAN FD frames, and hardware CRC calculation with flexible polynomial selection. The controller handles ISO 11898-1:2015 compliant frame formatting, including bit stuffing, arbitration, and error confinement-all without CPU intervention. R7F7016934AFP-C#BA1 maintains full message filtering and FIFO buffering at 5 Mbps under worst-case bus load.

Is R7F7016934AFP-C#BA1 pin-compatible with other RH850/F1KH variants?

R7F7016934AFP-C#BA1 uses the 216-pin LQFP package shared with RH850/F1KH-D8 family members including R7F7016834AFP-C#BA1 and R7F7016924AFP-C#BA1. Pin functions are fully compatible across this subset, enabling hardware reuse for memory- or feature-scaled derivatives. However, it is not compatible with F1KM-Sx or F1KH-D4 packages due to differing pin counts and signal allocations. R7F7016934AFP-C#BA1 maintains identical power, ground, reset, clock, and peripheral pin mappings within the D8 subgroup.

What debug and trace capabilities does R7F7016934AFP-C#BA1 provide?

R7F7016934AFP-C#BA1 includes ARM CoreSight-compliant debug infrastructure: SWD/JTAG interface for halt-mode debugging, Embedded Trace Macrocell (ETM) for instruction and data trace with 4GB address space, and Serial Wire Viewer (SWV) for real-time event streaming. It supports non-intrusive tracing at full CPU speed (up to 200 MHz), cycle-accurate instruction logging, and hardware breakpoints/watchpoints. R7F7016934AFP-C#BA1 also provides dedicated debug access ports for safety monitor and memory controller diagnostics, essential for ASIL-D validation workflows.
