For engineers reviewing the R4F24569DVRFQV datasheet, R4F24569DVRFQV pinout, R4F24569DVRFQV application, or R4F24569DVRFQV equivalent, key selection criteria include Flash endurance (10,000 write/erase cycles), operating temperature range (−40°C to +85°C), watchdog timer with windowed mode, and compatibility with H8S/2456R software libraries and development tools.

Technical Context

The R4F24569DVRFQV implements the H8S/2400 CPU core with 32-bit internal data paths, supporting both normal and advanced operating modes. It integrates a programmable clock pulse generator (CPG) with PLL, bus controller (BSC), and interrupt controller (INT) with 128 priority levels.

Peripheral integration includes two 16-bit timer pulse units (TPU) with PWM output, four serial communication interfaces (SCI) supporting UART and LIN, one CAN controller compliant with ISO 11898-1, and 8-channel 10-bit ADC with sample-and-hold. Memory protection is enforced via memory management unit (MMU)-like access control registers.

FAQ

What is the maximum operating frequency of the R4F24569DVRFQV?

The R4F24569DVRFQV operates at a maximum CPU clock frequency of 32 MHz, achieved using its on-chip PLL-based clock pulse generator. This frequency delivers a 31.25 ns instruction cycle time, enabling tight real-time loop execution. The R4F24569DVRFQV supports multiple clock sources including crystal, ceramic resonator, and external clock input, with configuration handled via the CPG module registers.

Does the R4F24569DVRFQV include a CAN controller?

Yes, the R4F24569DVRFQV integrates a fully compliant CAN 2.0B controller supporting both standard and extended frame formats, with 32 message objects, hardware acceptance filtering, and automatic retransmission. It requires an external CAN transceiver (e.g., SN65HVD230) for physical layer connection. The R4F24569DVRFQV's CAN module is accessible via dedicated CANTX/CANRX pins and supports baud rates up to 1 Mbps.

What is the Flash memory endurance specification for R4F24569DVRFQV?

The R4F24569DVRFQV specifies 10,000 write/erase cycles for its 512 KB on-chip Flash memory, validated under standard industrial conditions (3.3 V, 25°C). Endurance is maintained across the full operating temperature range (−40°C to +85°C), with wear leveling left to application-level implementation. Renesas recommends avoiding frequent sector erases in production firmware; the R4F24569DVRFQV supports block-wise erase for optimized update routines.

Is the R4F24569DVRFQV pin-compatible with other H8S/2456 family members?

The R4F24569DVRFQV shares the same 128-pin LQFP package and pin assignment with the R4F2456 and R4F2456R variants per Renesas Hardware User's Manual Rev.5.00. However, functional differences exist: R4F2456R lacks CAN functionality, and R4F2456 has identical peripherals but different Flash/RAM sizing. PCB layout is interchangeable only when CAN signals are not routed or terminated; the R4F24569DVRFQV remains the sole variant with full CAN 2.0B support in this footprint.

What development tools support the R4F24569DVRFQV?

The R4F24569DVRFQV is supported by Renesas' CS+ IDE (formerly High-performance Embedded Workshop), including C compiler, debugger, and flash programmer. Evaluation is enabled via the E8 emulator and compatible target boards such as the YRDKFX2456. Peripheral drivers and HAL libraries are provided in the H8S/2400 Software Manual and application notes like AN2456-002. The R4F24569DVRFQV also integrates with third-party tools supporting E8 debug interface and ELF/DWARF format.
