FAQ
What is the maximum operating frequency of the R4F24269NVRFQV?
The R4F24269NVRFQV supports a maximum CPU clock frequency of 32 MHz, achieved via its integrated CPG with PLL multiplier. This frequency is guaranteed across the full −40°C to +85°C industrial temperature range when powered at 3.3 V ±0.3 V. The R4F24269NVRFQV's timing specifications include setup/hold margins validated at this speed for all internal peripherals and external bus interfaces.
Does the R4F24269NVRFQV include on-chip debug capabilities?
Yes, the R4F24269NVRFQV integrates a full-featured on-chip debug interface compliant with Renesas E1 and E20 emulator platforms. It supports real-time trace, hardware breakpoints, register read/write, and memory access without requiring additional debug firmware - enabling rapid development and validation of safety-critical firmware on the R4F24269NVRFQV.
What package type is used for the R4F24269NVRFQV?
The R4F24269NVRFQV is supplied in a 100-pin LQFP (low-profile quad flat package) measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad (EPAD). This package provides superior thermal performance compared to standard PQFP variants and is optimized for automated SMT assembly in industrial-grade PCBs.
Can the R4F24269NVRFQV operate from a 5 V supply?
No, the R4F24269NVRFQV is specified exclusively for 3.3 V ±0.3 V operation. Its I/O pins are not 5 V tolerant, and applying 5 V to VCC or any pin may cause permanent damage. External level shifters are required when interfacing with 5 V peripherals, and the R4F24269NVRFQV must be powered from a regulated 3.3 V source meeting its current and ripple requirements.
Is the R4F24269NVRFQV supported by current Renesas development tools?
Yes, the R4F24269NVRFQV is fully supported by Renesas e² studio IDE, CS+ (formerly High-performance Embedded Workshop), and the Renesas Flash Programmer. All official device files, startup code, peripheral drivers, and example projects for the H8S/2426R group - including the R4F24269NVRFQV - are maintained in the latest versions of these tools.
