FAQ

What is the maximum operating frequency of the R7FS5D97E3A01CFP#AA0?

The R7FS5D97E3A01CFP#AA0 operates at a maximum CPU frequency of 200 MHz, achieved via its on-chip PLL with fractional divider. This frequency is sustained under full peripheral load with proper thermal management and voltage regulation per the datasheet's recommended operating conditions. The R7FS5D97E3A01CFP#AA0 maintains timing compliance across its entire industrial temperature range (−40°C to +85°C) when powered within the specified 2.7–3.6 V supply range.

Does the R7FS5D97E3A01CFP#AA0 support secure boot with cryptographic verification?

Yes, the R7FS5D97E3A01CFP#AA0 implements hardware-enforced secure boot using RSA-2048 signature verification of the primary bootloader image stored in flash. It validates signatures against embedded public keys before execution, and locks debug access if verification fails. This feature is integral to the R7FS5D97E3A01CFP#AA0's security subsystem and requires no external components to establish a root of trust at power-on.

What communication interfaces are integrated into the R7FS5D97E3A01CFP#AA0?

The R7FS5D97E3A01CFP#AA0 integrates USB 2.0 High-Speed and Full-Speed PHY, CAN FD controller (supporting up to 5 Mbps), Ethernet MAC with RMII interface, four serial communication interfaces (SCI), two SPI modules, and two I²C interfaces. These interfaces are independently clocked and support concurrent operation, enabling the R7FS5D97E3A01CFP#AA0 to serve as a multi-protocol industrial gateway without external bridge ICs.

How much user-accessible memory does the R7FS5D97E3A01CFP#AA0 provide?

The R7FS5D97E3A01CFP#AA0 provides 2 MB of on-chip flash memory (with ECC and dual-bank architecture) and 512 KB of SRAM. Of the SRAM, 64 KB is designated as backup RAM with battery-backed retention, and 128 KB supports parity checking. All memory regions are accessible via the R7FS5D97E3A01CFP#AA0's AHB/APB bus matrix with configurable wait states and burst support.

Is the R7FS5D97E3A01CFP#AA0 qualified for industrial temperature operation?

Yes, the R7FS5D97E3A01CFP#AA0 is rated for industrial temperature operation from −40°C to +85°C and conforms to Renesas' "Standard" quality grade, which covers industrial robots, machine tools, and factory automation equipment. Its electrical characteristics-including flash endurance (100K cycles), data retention (20 years), and timing parameters-are fully specified and tested across this range, as documented in the R7FS5D97E3A01CFP#AA0 datasheet.
