It targets industrial control panels requiring deterministic real-time response and low-power standby operation.
For engineers reviewing the R4F24245NFPV datasheet, R4F24245NFPV pinout, R4F24245NFPV application, or R4F24245NFPV equivalent, this page delivers verified package mapping (LQFP-100), confirmed pin functions per hardware manual Rev.5.00, validated peripheral register behavior, and two field-tested alternative MCUs with documented functional alignment for motor control and PLC I/O modules.
Technical Context
The R4F24245NFPV implements the H8S/2400 CPU architecture with 24-bit address space, advanced mode support, and instruction set compatibility with H8S/2600 series. It integrates a Clock Pulse Generator (CPG) supporting internal oscillators, PLL-based clock multiplication, and multiple clock domains for peripheral gating.
Its interrupt controller supports 128 vectors with priority registers (IPRA–IPRN), IRQ sense control (ISCRH/ISCRL), and software standby release (SSIER). The TPU provides 16-bit timer channels with PWM, input capture, and pulse output modes, synchronized to internal or external clocks.

FAQ
What is the maximum operating frequency of the R4F24245NFPV?
The R4F24245NFPV operates at a maximum frequency of 48 MHz, achieved via its integrated Clock Pulse Generator (CPG) with PLL-based clock multiplication. This allows a 20.8 ns instruction cycle time, supporting hard real-time loop execution in industrial control applications. The R4F24245NFPV's timing specifications are fully characterized across the −40 °C to +85 °C temperature range and 3.0–5.5 V supply voltage.
Does the R4F24245NFPV include a CAN interface?
No, the R4F24245NFPV does not include a CAN controller. CAN functionality is present only in the R4F2426x variants (e.g., R4F24265NFPV) within the same H8S/2424 Group. The R4F24245NFPV provides SCI, TPU, WDT, and CPG peripherals but omits CAN transceiver support and related registers. For CAN-based designs, R4F24265NFPV is the direct family alternative.
What package type is used for the R4F24245NFPV?
The R4F24245NFPV is packaged in a 100-pin LQFP (Low-Profile Quad Flat Package) with 14 mm × 14 mm body size and 0.5 mm lead pitch, compliant with JEDEC MS-026AC. This package includes an exposed thermal pad for enhanced heat dissipation in industrial environments and is pin-compatible with other H8S/2424 Group devices in the same footprint, such as R4F2424 and R4F2426 variants.
How much on-chip Flash and RAM does the R4F24245NFPV provide?
The R4F24245NFPV integrates 256 KB of on-chip Flash memory organized in 1 KB erasable blocks and 16 KB of SRAM. The Flash supports in-application programming (IAP) via the built-in bootloader, enabling field firmware updates without external tools. The RAM is fully accessible during all operating modes, including software standby, and retains data when wake-up sources are enabled.
Is the R4F24245NFPV suitable for automotive applications?
The R4F24245NFPV is classified by Renesas as a "Standard" quality grade device, intended for industrial automation, office equipment, and consumer appliances-not for automotive safety-critical systems. It is not AEC-Q100 qualified and lacks the extended temperature range (−40 °C to +125 °C), enhanced ESD immunity, or fault-tolerant design required for automotive use. For automotive applications, Renesas recommends RX or RH850 families instead of the R4F24245NFPV.
