FAQ

What is the maximum operating frequency of the R4F24248DFPV?

The R4F24248DFPV operates at a maximum frequency of 33 MHz, achieved via its integrated clock pulse generator (CPG) with PLL multiplication. This yields a 30 ns instruction cycle time, enabling precise timing for real-time control tasks such as PWM generation and interrupt-driven I/O handling. The R4F24248DFPV maintains this performance across its full industrial temperature range (−40°C to +85°C) under 4.5–5.5 V supply conditions.

Does the R4F24248DFPV support in-circuit debugging?

Yes, the R4F24248DFPV supports full in-circuit debugging via IEEE 1149.1 JTAG interface. This allows non-intrusive breakpoints, register inspection, memory read/write, and real-time trace without halting peripheral operation. The R4F24248DFPV's on-chip emulator eliminates the need for external debug probes in most development scenarios, streamlining firmware validation for industrial control applications.

How many I/O pins does the R4F24248DFPV provide, and what are their electrical characteristics?

The R4F24248DFPV provides 79 general-purpose CMOS I/O pins in its 100-pin LQFP package. Each pin supports programmable pull-up resistors, noise filtering (1–16 clock cycles), and high-current drive (20 mA sink/source). All I/Os are 5 V tolerant and rated for 6 V absolute maximum, ensuring interoperability with legacy 5 V logic and industrial sensors without level-shifting circuitry.

What is the flash memory endurance specification for the R4F24248DFPV?

The R4F24248DFPV features 512 KB of on-chip flash memory rated for 10,000 write/erase cycles per sector, with automatic erase verification and error detection. This endurance level supports field firmware updates in industrial equipment with multi-year service intervals. The R4F24248DFPV also supports read-while-write operation, allowing background programming without interrupting real-time application execution.

Is the R4F24248DFPV qualified for industrial temperature operation?

Yes, the R4F24248DFPV is qualified for industrial temperature operation from −40°C to +85°C and classified by Renesas as a "Standard" grade device. It meets Renesas' specifications for electrical characteristics, timing, and reliability across this range, making it suitable for deployment in factory automation, motor drives, and embedded instrumentation without derating or thermal mitigation.
