R5F52205BDFP#10 概要
What is a microcontroller (MCU)? A microcontroller is a single-chip computer that integrates a CPU core, program memory (flash), data memory (SRAM), and peripherals such as timers, communication interfaces, and analog blocks. The RX220 family sits within the broader taxonomy: 32-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. RXv1 cores use the Renesas RX instruction set, delivering high code density and deterministic interrupt response suited to real-time embedded designs.
Key features of the R5F52205BDFP#10 include 128KB flash with 8KB SRAM, a 32MHz maximum operating frequency, and an industrial temperature grade of -40C to +85C. The device integrates a minimum set of peripherals aimed at entry-level designs: multiple timers, a 12-bit A/D converter, and serial communication interfaces. The 100-pin LFQFP package provides ample I/O for typical embedded applications while remaining cost-effective for high-volume production.
The RX220 Group achieves high pin-arrangement and software compatibility with the higher-end RX210 Group, allowing engineers to migrate designs upward as memory or peripheral needs grow. This compatibility reduces design risk and accelerates time-to-market when scaling from entry-level to mid-range applications.
Typical applications include home appliances, consumer electronics, industrial sensor nodes, simple motor control, and battery-powered measurement instruments. The wide 1.62V-5.5V operating range supports both 3.3V and 5V system designs without external level translation.
When designing with this MCU, ensure the power supply rail stays within 1.62V-5.5V during all transient conditions, and follow Renesas RX220 hardware manual guidance for oscillator and reset circuit design. Unused pins should be configured with appropriate input pull-ups or left open per the hardware manual to minimize power consumption.

主な用途
R5F52205BDFP#10 の用途: 6 件s: Home Appliance Control, Industrial Sensor Node, Consumer Electronics Remote Control, Battery-Powered Measurement Instrument, Simple Motor Control (BLDC / Stepper), IoT Edge Device Controller.
Home Appliance Control
The R5F52205BDFP#10 fits home appliance control boards with its 128KB flash supporting user-interface state machines and its 100-LFQFP providing ample I/O for keypad scanning, LED driving, and relay control. The 1.62V-5.5V supply range accepts a 5V rectified rail directly without LDO pre-regulation. Its RXv1 core delivers deterministic interrupt response for safety-critical tasks like over-temperature shutdown. Use the device to coordinate motor drive, temperature sensing via the 12-bit A/D, and UART communication to a main control panel, with minimum BOM cost.
おすすめ
Industrial Sensor Node
For industrial 4-20mA sensor nodes, the R5F52205BDFP#10 supplies 128KB flash for calibration tables and linearization routines, with 8KB SRAM sufficient for cyclic buffers. The 12-bit A/D converter pairs with external sensor bridges to digitize pressure or temperature. Operating at -40C to +85C, it tolerates factory-floor environments; the 1.62V minimum supply supports 2xAA battery backup during line-power outages. Place a watchdog timer in firmware and rely on the RXv1 hardware multiplier for fast FFT-based vibration analysis on rotating equipment.
おすすめ
Consumer Electronics Remote Control
The R5F52205BDFP#10 is a strong fit for advanced remote controls with displays, where its 32MHz RXv1 core and 128KB flash can drive IR/RF protocol stacks (RC5, NEC, BLE HID) plus LCD control logic. The 100-LFQFP exposes UART, SPI, and I2C ports for radio modules and LCD drivers; the wide 1.62V-5.5V supply permits direct 3V coin-cell or USB-powered operation. Eight kilobytes of SRAM is ample for HID report buffers and command queues, while the industrial temperature grade supports outdoor and automotive cabin environments.
おすすめ
Battery-Powered Measurement Instrument
For portable DMMs and handheld test instruments, the R5F52205BDFP#10 provides enough flash (128KB) for measurement firmware and SRAM (8KB) for sample buffers, while the 1.62V minimum supply extends battery life when running from depleted 2xAA cells. The 12-bit A/D converter supports voltage/current measurements with appropriate front-end scaling, and the RXv1 core's deterministic timing enables accurate RMS calculations. Place the MCU in software-standby when not measuring to drop quiescent current; the 100-LFQFP remains manageable in handheld enclosures.
おすすめ
Simple Motor Control (BLDC / Stepper)
The R5F52205BDFP#10 supports 6-step BLDC or stepper motor commutation with its 32MHz RXv1 core and rich timer peripherals. The 128KB flash stores trapezoidal or simple FOC algorithms; 8KB SRAM holds encoder feedback and current-loop state variables. The 100-LFQFP exposes PWM outputs, encoder inputs, and ADC channels for back-EMF sensing. Note that for safety-critical motor drives consider the higher-end RX231 family; for entry-level fans, pumps, and small appliances the RX220 is sufficient and cost-effective.
おすすめ
IoT Edge Device Controller
The R5F52205BDFP#10 works well as an IoT edge controller, bridging sensors to wireless MCUs via SPI or UART. With 128KB flash and 8KB SRAM it can run local filtering and decision logic before passing data upstream to a Wi-Fi or BLE module. The 1.62V-5.5V range accommodates solar/battery energy harvesting front-ends, and the industrial temperature grade supports outdoor IoT deployments. Use the device to aggregate multiple I2C sensors, drive a status LED, and forward data through an NRF52 or ESP32 companion radio.

主な差別化要因
- Industry-leading code density from RXv1 instruction set （vs PIC16F1939T-I/PT)
- Wide 1.62V-5.5V single-supply operation without LDO （vs GD32F130R8T6)
- 100% pin/software compatible with RX210 Group for upward migration （vs R5F211B4SP#W4 (R8C))
設計ノート
Decouple the VCC pin (pin 100) with a 0.1uF ceramic capacitor placed within 5mm of the pin, plus a bulk 10uF tantalum or ceramic at the supply entry point. The VCL pin (pin 1) requires its own 0.1uF capacitor to VSS to stabilize the internal voltage regulator; do not omit this capacitor or the MCU may exhibit reset behavior under transient loads.
Route the analog AVCC0 and VREFH0 pins through a ferrite bead from the digital VCC rail, with separate decoupling (0.1uF + 10uF) on each side of the bead, to prevent digital switching noise from coupling into ADC measurements. Keep analog traces (AN000-AN007) short and away from high-frequency digital lines like XTAL or PWM outputs to preserve ADC accuracy.
Do not leave the MODE/MD pin floating - tie it to VCC for single-chip boot mode or to VSS for USB-boot mode. Configure all unused I/O pins per the RX220 Hardware Manual (typically set as outputs with low level) to minimize quiescent current. Watchdog timer reset must be enabled during firmware bring-up; the RXv1 watchdog defaults to disabled after reset.
Estimated: At 32MHz CPU clock with all peripherals active and 3.3V supply, the R5F52205BDFP#10 consumes approximately 30mA (typical). On a 4-layer FR-4 PCB with no thermal vias under the LFQFP, theta_JA is approximately 50 C/W; with a continuous 30mA draw, the junction temperature rise is roughly 5C above ambient, well within the -40C to +85C industrial range.
コンプライアンス情報
RoHS compliance confirmed via LCSC listing. Industrial temperature grade -40C to +85C; not AEC-Q100 automotive qualified - consider RX230 or RX65N family for automotive applications.
