FAQ

What is the maximum operating frequency of the R4F24269NVFQV?

The R4F24269NVFQV supports a maximum CPU clock frequency of 32 MHz, achieved using the on-chip PLL with an external crystal (1–20 MHz) or resonator. This frequency is fully supported across the full industrial temperature range (−40°C to +85°C) and supply voltage range (3.0–5.5 V). The R4F24269NVFQV maintains timing compliance under worst-case conditions without derating, enabling predictable real-time execution in safety-critical loops.

Does the R4F24269NVFQV include a CAN controller, and what version does it support?

Yes, the R4F24269NVFQV integrates a full CAN 2.0B controller compliant with ISO 11898-1, supporting both standard (11-bit) and extended (29-bit) identifiers, error frame detection, automatic retransmission, and 32 configurable message objects. It operates at up to 1 Mbit/s and includes dedicated transmit/receive mailboxes and acceptance filtering - all implemented in hardware without CPU intervention. This makes the R4F24269NVFQV suitable for automotive and industrial CAN networks where deterministic latency and protocol fidelity are essential.

What is the Flash memory size and endurance specification for the R4F24269NVFQV?

The R4F24269NVFQV contains 512 KB of on-chip Flash memory, organized in 1 KB erasable blocks. Renesas specifies a minimum endurance of 10,000 write/erase cycles per block and data retention of 20 years at +85°C. The Flash supports in-application programming (IAP), enabling firmware updates over CAN or SCI without external programmers. This capacity allows storage of complex control algorithms, calibration data, and event logs - critical for R4F24269NVFQV deployments in field-upgradable industrial equipment.

Is the R4F24269NVFQV pin-compatible with other H8S/2426 family members?

The R4F24269NVFQV uses the same 100-pin LQFP package and shares identical pin assignments with the R4F2426 and R4F2426R variants within the H8S/2426 group. Pin functions - including power, clock, CAN, SCI, ADC, and I/O - are electrically and physically identical across these variants. However, feature enablement (e.g., CAN presence, Flash size, or peripheral clock gating) differs per part number, so firmware must be validated for the specific variant. This ensures hardware reuse across design iterations while preserving layout integrity for the R4F24269NVFQV.

What debug interfaces are supported by the R4F24269NVFQV?

The R4F24269NVFQV includes a dedicated on-chip debug (OCD) interface accessible via a 6-pin debug connector (including CLK, RST, TDI, TDO, TMS, TCK). It supports full real-time debugging: hardware breakpoints, watchpoints, register and memory inspection, and instruction trace - all without halting system operation. No external emulator is required; standard Renesas E1/E20 debuggers or compatible JTAG tools can program and debug the R4F24269NVFQV directly. This simplifies development and validation of time-sensitive applications like motor control or CAN messaging stacks.
