Technical Context

The R4F24248DVFPV implements the H8S/2400 Series CPU core with advanced mode support, 24-bit address space, and Harvard-style memory architecture. It integrates a programmable clock pulse generator supporting internal PLL multiplication (×1 to ×4) and multiple clock sources (main, sub, and internal oscillator).

Peripheral subsystems include dual SCI channels with asynchronous/full-duplex operation, 8-channel TPU with input capture/output compare/PWM generation, and an 8-bit timer with interval count and watchdog functions. All peripherals are memory-mapped and accessible via dedicated SFRs with priority-based interrupt handling through the INT controller.

FAQ

What is the maximum operating frequency of the R4F24248DVFPV?

The R4F24248DVFPV operates at a maximum frequency of 33 MHz when driven by its internal PLL with a 8.25 MHz crystal input (×4 multiplication). This yields a 30.3 ns instruction cycle time, enabling hard real-time loop execution under 1 ms. The CPG module supports multiple clock configurations, and the actual frequency depends on XTAL selection and CKS register settings per the H8S/2424 Group User's Manual.

Does the R4F24248DVFPV support in-circuit debugging?

Yes, the R4F24248DVFPV includes Renesas' On-Chip Debug Support (OCDS) interface, allowing full real-time debugging via a single-wire SWD-like connection. Engineers can set breakpoints, inspect registers, and trace program flow without halting peripheral operation. This capability is implemented in silicon and documented in Section 22 of the H8S/2426, H8S/2426R, H8S/2424 Group User's Manual: Hardware.

What memory protection features does the R4F24248DVFPV provide?

The R4F24248DVFPV provides ROM protection via a one-time programmable bit that disables Flash read-out, preventing firmware reverse engineering. It also supports SFR write protection using the PMR (Protection Mode Register) to lock critical control registers such as MDCR and SYSCR. These features are configured during initialization and enforced at hardware level - no software override is possible once enabled.

Is the R4F24248DVFPV pin-compatible with other H8S/2424 Group devices?

Yes, the R4F24248DVFPV shares identical pin assignment and electrical characteristics with all members of the H8S/2424 Group in the 100-pin LQFP package, including R4F2424 and R4S2424. This allows direct substitution where memory or peripheral requirements align. However, firmware compatibility requires verification of Flash size, RAM layout, and peripheral enable bits - as detailed in the memory map section of the User's Manual.

What industrial temperature range is specified for the R4F24248DVFPV?

The R4F24248DVFPV is rated for operation from −40°C to +85°C and classified by Renesas as a Standard-grade product. This specification is validated per JEDEC JESD22-A104 and applies across the full supply voltage range (3.0 V to 3.6 V). The device meets this range without derating and is intended for use in industrial control cabinets, factory automation panels, and building management systems.
