It operates at up to 33 MHz and targets industrial control, motor drive, and embedded instrumentation applications requiring deterministic real-time response.

For engineers reviewing the R4F24569NVFQV datasheet, R4F24569NVFQV pinout, R4F24569NVFQV application, or R4F24569NVFQV equivalent, key selection criteria include Flash endurance (10,000 write/erase cycles), operating voltage range (3.0 V to 5.5 V), ambient temperature rating (–40°C to +85°C), and support for H8S/2400-compatible instruction set architecture with advanced mode addressing.

Technical Context

The R4F24569NVFQV implements the H8S/2456 core - a superset of the H8S/2000 CPU with enhanced addressing modes, extended register usage, and improved interrupt latency. It supports Normal and Advanced CPU operating modes, enabling flexible code density vs. performance trade-offs in resource-constrained systems.

Its peripheral integration includes dual SCI channels (asynchronous UART), 16-bit TPU with PWM output capability, 8-bit TMR for interval timing, and a programmable watchdog timer with windowed operation. Memory protection is enforced via on-chip bus controller (BSC) with configurable wait-state control and access arbitration.

Key Specifications

Pinout & Package

The R4F24569NVFQV is housed in a 128-pin LQFP package with exposed thermal pad (code: NVFQV), optimized for thermal dissipation in continuous-duty industrial applications. Pin assignments are defined across four functional groups: power/ground, clock/reset, I/O ports (P0–P15), and peripheral-specific signals (SCI, TPU, WDT, CPG).

FAQ

What is the maximum operating frequency of the R4F24569NVFQV?

The R4F24569NVFQV operates at a maximum frequency of 33 MHz across its full specified voltage range (3.0 V to 5.5 V). This frequency is derived from the on-chip clock pulse generator (CPG), which multiplies an external crystal or resonator input using internal PLL circuitry. The R4F24569NVFQV achieves 22.7 MIPS at this speed, enabling tight control loop execution in motor drive and power conversion applications.

Does the R4F24569NVFQV support in-system programming (ISP)?

Yes, the R4F24569NVFQV supports in-system programming via its on-chip Flash memory and dedicated bootloader ROM. Firmware updates can be performed through SCI0 or SCI1 using Renesas' standard Flash programming protocol without requiring external programmers. The R4F24569NVFQV includes Flash security lock bits to prevent unauthorized access during ISP operations, preserving intellectual property in deployed systems.

What peripheral modules are integrated into the R4F24569NVFQV?

The R4F24569NVFQV integrates a 16-bit TPU with PWM and capture/compare functions, two full-duplex SCI channels (UART), an 8-bit timer (TMR), a watchdog timer (WDT) with window mode, a clock pulse generator (CPG), and a bus controller (BSC). These peripherals are tightly coupled to the H8S/2456 CPU core and share memory-mapped registers accessible without software overhead, making the R4F24569NVFQV suitable for time-critical embedded control.

Is the R4F24569NVFQV pin-compatible with other H8S/2456 family members?

Yes, the R4F24569NVFQV shares identical pin assignment and electrical characteristics with other members of the H8S/2456 group in the same 128-pin LQFP package (e.g., R4F24568NVFQV, R4F24569NVPQV). Pin-to-pin compatibility extends to power, clock, reset, I/O ports, and peripheral signal mapping, allowing hardware reuse across variants differing only in Flash/RAM size or package type. This simplifies design migration and inventory consolidation for the R4F24569NVFQV.

What is the operating temperature range certified for the R4F24569NVFQV?

The R4F24569NVFQV is rated for industrial operation from –40°C to +85°C ambient temperature. This range is validated per Renesas' Standard quality grade classification and applies to all electrical specifications, including Flash write/erase endurance, RAM retention, and peripheral timing accuracy. The R4F24569NVFQV's thermal design - including its LQFP package with exposed pad - ensures reliable operation under sustained load in enclosed control cabinets without forced air cooling.
