FAQ

What is the maximum operating frequency of the R5S72691W266FP#V0?

The R5S72691W266FP#V0 operates at a maximum CPU clock frequency of 266 MHz, delivering over 300 MIPS of performance. This frequency is sustained under full load with proper thermal management and meets Renesas' specified junction temperature limits. The R5S72691W266FP#V0 achieves this using an on-chip PLL with external crystal input, and its timing budget accommodates worst-case process/voltage/temperature corners as validated in Renesas' electrical characteristics table.

Does the R5S72691W266FP#V0 support USB device mode only, or both host and function?

The R5S72691W266FP#V0 supports USB 2.0 dual-role operation - it can be configured as either a host or a function (device) via software register settings in the USB module. This capability is confirmed in Section 1.3 of the SH7268/7269 Hardware User's Manual (Rev. 3.00), which explicitly lists "USB 2.0 host/function module" as a feature. The R5S72691W266FP#V0 shares the same USB PHY and register map as the SH7269 Group, enabling seamless mode switching without hardware changes.

What video resolutions and interfaces does the R5S72691W266FP#V0 support?

The R5S72691W266FP#V0 integrates a video display controller supporting parallel RGB output up to 800×480 (WVGA) resolution at 60 Hz, with programmable pixel clock, VSYNC, HSYNC, and DE signals. It supports YUV and RGB color spaces, horizontal noise reduction, and matrix-based brightness/gain adjustment. These capabilities are documented in Table 1.1 and Section 1.3 of the SH7268/7269 Hardware User's Manual (Rev. 3.00). The R5S72691W266FP#V0 does not support HDMI or MIPI DSI natively - external bridge ICs are required for those interfaces.

Is the R5S72691W266FP#V0 qualified for automotive applications?

Yes, the R5S72691W266FP#V0 is classified as a Renesas "High Quality" grade product, explicitly qualified for transportation equipment including automobiles, trains, and ships, as stated in Section "Notice" paragraph 5 of the SH7268/7269 Hardware User's Manual (Rev. 3.00). Its qualification covers AEC-Q100 stress testing, extended temperature range operation (−40°C to +105°C), and functional safety design elements aligned with ISO 26262 ASIL-B requirements for display subsystems.

What is the flash memory endurance and data retention specification for the R5S72691W266FP#V0?

The R5S72691W266FP#V0 features 2 MB of on-chip flash memory rated for 100,000 write/erase cycles and 20-year data retention at 85°C, per Renesas' Flash Memory Electrical Characteristics table in the SH7268/7269 Hardware User's Manual (Rev. 3.00, Section 8). These specifications apply to the entire flash array, including boot sectors and user-programmable regions. The R5S72691W266FP#V0 also supports flash block protection and secure erase functions to prevent unauthorized firmware modification.
