Technical Context

The R4F24249DVFPV implements the H8S/2400 Series CPU architecture with 24-bit address space, 16-bit data bus, and Harvard-style instruction/data memory separation. It integrates a programmable clock pulse generator (CPG) supporting multiple PLL and divider configurations, enabling precise system clock derivation from external crystals (1–20 MHz) or ceramic resonators.

Its interrupt controller supports 128 vectors with priority-based nesting and software-selectable edge/polarity sensing on external IRQ pins. Peripheral modules-including two 16-bit TPU channels with PWM output, four asynchronous SCI interfaces, and a 10-bit 8-channel ADC with sample-and-hold-share dedicated DMA channels for deterministic real-time response.

FAQ

What is the maximum operating frequency of the R4F24249DVFPV?

The R4F24249DVFPV supports a maximum CPU clock frequency of 33 MHz when using the on-chip PLL with an external 8 MHz crystal. Its internal clock pulse generator allows configuration of system clocks for peripherals independently - for example, running the ADC at 12 MHz while the CPU runs at 33 MHz. This frequency is validated across the full industrial temperature range (−40°C to +85°C) and 3.3 V ±10% supply.

Does the R4F24249DVFPV include hardware debug support?

Yes, the R4F24249DVFPV integrates a full JTAG debug interface compliant with IEEE 1149.1, enabling non-intrusive real-time tracing, hardware breakpoints, and register inspection without halting program execution. This interface is accessible via standard Renesas E2 emulator or compatible third-party tools and remains functional even when flash protection is enabled for read-only locking.

What are the flash memory endurance and data retention specifications for the R4F24249DVFPV?

The R4F24249DVFPV specifies 10,000 write/erase cycles for its 256 KB on-chip flash memory, with data retention guaranteed for 20 years at +85°C and 100 years at +25°C. Sector erase granularity is 128 bytes, and programming is performed in 2-byte words. These values are measured per JEDEC JESD22-A117 and confirmed in Renesas' qualification reports for the H8S/2424 Group.

Can the R4F24249DVFPV operate in extended temperature environments?

The R4F24249DVFPV is rated for industrial temperature operation from −40°C to +85°C, with full electrical specification compliance across this range. It does not support automotive-grade (−40°C to +125°C) or extended industrial (−40°C to +105°C) variants. Thermal derating is not required within its specified range, and all timing parameters - including ADC conversion time and interrupt latency - are guaranteed at both extremes.

How is the ADC performance characterized on the R4F24249DVFPV?

The R4F24249DVFPV features a 10-bit successive approximation ADC with eight input channels, 1.25 µs typical conversion time, and ±1 LSB integral nonlinearity (INL) over the full operating range. It supports software and hardware trigger sources, configurable sample-and-hold duration, and built-in offset calibration. The ADC reference is internally derived from VCC or externally selectable via AVREF pin, with dedicated analog ground (AVSS) for noise isolation.
