FAQ
What is the maximum operating frequency of the R5F566NNHGBD#20?
The R5F566NNHGBD#20 operates at a maximum CPU clock frequency of 120 MHz, achieved using its on-chip PLL with external crystal or oscillator input. This frequency is fully supported across the entire industrial temperature range (−40°C to +85°C) and enables sub-microsecond interrupt response and deterministic real-time execution for demanding control applications.
Does the R5F566NNHGBD#20 include an integrated Ethernet PHY?
No, the R5F566NNHGBD#20 includes only an Ethernet MAC layer. An external PHY IC is required for physical layer connectivity. The device provides all necessary MII/RMII signals (ETH_MDC, ETH_MDIO, ETH_RXD[3:0], ETH_TXD[3:0], ETH_REF_CLK) and supports both 10/100 Mbps operation with full-duplex capability when paired with a compatible PHY.
What safety certifications does the R5F566NNHGBD#20 support?
The R5F566NNHGBD#20 includes hardware features aligned with IEC 61508 SIL2 requirements, including ECC protection on flash and SRAM, lockstep timer modules, and a dedicated safety monitor unit. While the device itself is not pre-certified, Renesas provides safety manuals, FMEDA reports, and diagnostic software libraries to accelerate functional safety certification of end systems built around the R5F566NNHGBD#20.
Can the R5F566NNHGBD#20 execute firmware updates without interrupting operation?
Yes, the R5F566NNHGBD#20 supports seamless firmware updates via its dual-bank flash architecture. While one bank executes the active application, the other bank can be reprogrammed in the background. The device includes hardware-assisted bank switching and interrupt masking to ensure zero-downtime transitions, making it ideal for mission-critical industrial equipment that cannot tolerate reboot cycles.
What development tools are officially supported for the R5F566NNHGBD#20?
Renesas provides full toolchain support for the R5F566NNHGBD#20, including e2 studio IDE, CS+ compiler suite, and the Renesas Flash Programmer.
