Overview
R4F24269DVFQV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2400 Series, featuring a 32 MHz max CPU clock, 256 KB on-chip flash memory, 16 KB RAM, and integrated peripherals including TPU (16-bit timer pulse unit), SCI (serial communication interface), WDT (watchdog timer), and CPG (clock pulse generator). It targets industrial control panels requiring deterministic real-time response and extended temperature operation.
For engineers reviewing the R4F24269DVFQV datasheet, R4F24269DVFQV pinout, R4F24269DVFQV application, or R4F24269DVFQV equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C industrial temperature grade, 32 MHz core frequency, and support for H8S/2400-series instruction set compatibility with legacy firmware migration paths.
Technical Context
The R4F24269DVFQV implements the H8S/2426R variant of the H8S/2400 CPU core, supporting both Normal and Advanced operating modes with 24-bit address space expansion. Its system control includes programmable wait-state insertion, on-chip power-on reset, and low-power software standby mode with IRQ wake-up capability.
Peripheral integration follows the H8S/2426 group architecture: dual SCI channels (asynchronous UART mode), 8-channel TPU with PWM output and input capture, 16-channel interrupt controller with priority encoding, and bus controller (BSC) supporting external memory expansion up to 16 MB with configurable timing parameters.

FAQ
What is the maximum operating frequency of the R4F24269DVFQV?
The R4F24269DVFQV supports a maximum CPU clock frequency of 32 MHz, achieved using an external crystal or oscillator connected to the EXTAL/XTAL pins, with internal clock pulse generator (CPG) dividing and distributing clocks to CPU and peripherals. This frequency is guaranteed across the full industrial temperature range (-40°C to +85°C) and 3.0 V to 3.6 V supply voltage.
Does the R4F24269DVFQV include on-chip debug support?
Yes, the R4F24269DVFQV integrates on-chip debugging capability via the H8S/2400-series standard debug interface, supporting breakpoints, watchpoints, and single-step execution through Renesas E1/E20 emulators. The R4F24269DVFQV uses dedicated pins (MD0, MD1, and RES#) for debug connection without requiring additional GPIO resources.
Can the R4F24269DVFQV operate from a 3.3 V supply only?
Yes, the R4F24269DVFQV is specified for single-supply operation from 3.0 V to 3.6 V - no 5 V or auxiliary voltage rails are required. All I/O pins are 5 V-tolerant on input, allowing direct interfacing with legacy 5 V logic without level shifters, while maintaining 3.3 V output swing for low-power compatibility.
What is the flash memory endurance specification for the R4F24269DVFQV?
The R4F24269DVFQV features 256 KB of on-chip flash memory rated for 100,000 write/erase cycles and 20 years of data retention at 85°C. Sector erase and byte-programmable functionality enable robust in-field firmware updates, and the R4F24269DVFQV includes hardware lock bits to prevent accidental overwrite of critical bootloader sections.
Is the R4F24269DVFQV pin-compatible with other H8S/2426 family members?
Yes, the R4F24269DVFQV is fully pin-compatible with other 100-pin LQFP variants in the H8S/2426 group, including R4F24268DVFQV and R4F2426ADVFQV. Identical pin assignments, power sequencing, and reset behavior allow drop-in replacement within the same package footprint - differences are limited to flash/RAM capacity and are transparent to PCB layout and peripheral wiring.
