FAQ

What is the maximum operating frequency of the R4F24568NVFQV?

The R4F24568NVFQV supports a maximum CPU clock frequency of 32 MHz, achieved using its on-chip PLL with external crystal (1–20 MHz) or external clock input. This frequency is guaranteed across the full industrial temperature range (−40°C to +85°C) and 3.0–3.6 V supply voltage. The R4F24568NVFQV's CPG module allows dynamic clock switching between main, sub, and PLL-derived clocks without system interruption.

Does the R4F24568NVFQV include a built-in CAN transceiver?

No, the R4F24568NVFQV integrates a CAN protocol controller compliant with ISO 11898-1:2003 but does not include a physical layer transceiver. External high-speed CAN transceivers such as the NXP TJA1042 or Texas Instruments SN65HVD230 must be used to connect the R4F24568NVFQV to the CAN bus. The R4F24568NVFQV provides dedicated CANTX and CANRX pins that interface directly to the transceiver's TXD and RXD lines.

What debugging interface does the R4F24568NVFQV support?

The R4F24568NVFQV supports on-chip debugging via the Renesas E10A-USB or E20 emulator through the 14-pin JTAG interface (IEEE 1149.1 compliant). Debug features include hardware breakpoints, real-time trace, memory/register inspection, and flash programming. The R4F24568NVFQV's debug port remains functional even when the Flash security bits are set to restrict read-out, enabling secure field updates.

Is the R4F24568NVFQV RoHS-compliant and halogen-free?

Yes, the R4F24568NVFQV is RoHS-compliant (EU Directive 2011/65/EU) and halogen-free per Renesas' green policy (J-STD-709). The LQFP package uses lead-free matte tin plating and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. Full compliance documentation, including material declarations and test reports, is available from Renesas' official product page for the R4F24568NVFQV.

How many independent PWM outputs can the R4F24568NVFQV generate simultaneously?

The R4F24568NVFQV's Timer Pulse Unit (TPU) supports up to eight independent 16-bit PWM channels with configurable duty cycle, period, polarity, and dead-time insertion. Each channel operates autonomously with double-buffered registers, enabling glitch-free updates during runtime. These PWM outputs are used directly by the R4F24568NVFQV for motor control, LED dimming, and DC-DC converter gate driving without CPU intervention.
