R5F21217JFP 概要
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, and peripherals into one component. This MCU belongs to the broader hierarchy of embedded controllers, which also includes general-purpose MCUs, real-time controllers, and application-specific processors. Its 16-bit R8C CPU core and high instruction efficiency make it suitable for compact embedded-control systems where deterministic control, peripheral integration, and low board complexity matter.
The primary verified features are a 20 MHz maximum clock, 48 KB flash memory, 16-bit architecture, R8C/2x/21 family membership, and a 48-pin plastic molded LQFP package. The Renesas product page states that the device uses a high-performance silicon-gate CMOS process and has a 1 MB address space. The distributor record also lists 48+2K memory, indicating 48 KB of flash plus an additional 2 KB resource, although the exact memory map is not specified in the supplied data.
Typical application areas include industrial automation, embedded instruments, motor and actuator controllers, digital control panels, communication modules, and consumer devices requiring a compact 16-bit controller. The 3 V to 5 V operating range supports conventional embedded supply rails, while the -40°C to +85°C commercial temperature range supports industrial-temperature designs. Exact peripheral functions, RAM size, timer resources, communications interfaces, and electrical limits should be confirmed against the manufacturer datasheet before schematic capture.
The most important PCB consideration is the 48-pin LQFP footprint. Place the MCU close to its bypass capacitors and route sensitive signals away from noisy switching nodes. Confirm the manufacturer pinout and exposed support requirements rather than relying on distributor-only descriptions. For replacement decisions, firmware compatibility, clock behavior, memory size, peripheral mapping, and package pin assignment must all be checked.
This page combines verified distributor specifications, official Renesas product information, pricing references, package details, and engineering-oriented selection guidance. Because the supplied data does not include the complete electrical table or complete pin assignment, unspecified parameters are intentionally marked for verification rather than inferred.

Industrial automation controller
The R5F21217JFP fits compact industrial automation controllers because its verified 16-bit R8C core, 20 MHz maximum clock, 48 KB flash, and -40°C to +85°C operating range support responsive embedded control. It can manage digital I/O, sequencing logic, communications glue, and local supervisory functions in a 48-pin LQFP device. The design should budget regulator headroom and confirm the exact peripheral map before assigning functions. Firmware must also be tested for worst-case interrupt latency and startup behavior. This is a suitable platform for machine-control modules that need deterministic embedded processing without a high-end processor or external memory expansion.
おすすめ
Motor and actuator control
R5F21217JFP is suitable for small motor and actuator control systems that require deterministic control logic, local timing, and compact embedded firmware storage. Its 20 MHz maximum clock and 16-bit R8C architecture can support state-machine execution, protection logic, and coordination of external drivers. The MCU should sit close to power-stage sensing and gate-driver circuitry, while analog and switching nodes must be isolated to prevent noise injection. Exact timer channels, compare outputs, and capture inputs are not included in the supplied data and must be checked before selecting it for a particular motor topology.
おすすめ
Digital instrument and measurement controller
The R5F21217JFP can serve as the control processor in a digital instrument when the design needs a 16-bit embedded architecture, 20 MHz operating capability, and 48 KB firmware space in a 7 x 7 mm LQFP package. Typical duties include front-panel state management, calibration sequencing, data formatting, and supervision of external sensors or converters. The MCU is not presented here as a precision analog front end, so analog accuracy and noise performance depend on the external signal chain. Validate ADC-related functions, reference requirements, sampling requirements, and timing against the full manufacturer datasheet.
おすすめ
Communication equipment interface
R5F21217JFP is a reasonable candidate for a communication-equipment interface controller when the system needs local protocol handling, supervisory logic, and nonvolatile firmware storage. Its 48 KB flash provides room for embedded application code, while the 3 V to 5 V operating range simplifies interface with conventional digital rails. The MCU should be placed behind appropriately terminated communication drivers rather than connected directly to long cables. Check the complete UART, SPI, I2C, timer, and interrupt resources in the datasheet. Firmware timing and buffer sizing must account for protocol latency and line-noise margin.
おすすめ
Digital control panel
The R5F21217JFP can be used in a digital control panel to run menu logic, button handling, status indicators, and supervisory sequencing in a compact embedded platform. Its 48-pin LQFP package provides a defined footprint for board-level integration, while the 16-bit R8C core and 20 MHz clock provide ample headroom for event-driven control software. Panel designs should budget current for displays and indicators, provide debounce and ESD protection, and keep display interfaces away from sensitive timing paths. Exact I/O count and package-level multiplexing must be verified because those details are not included in the supplied snippets.
おすすめ
Embedded consumer appliance control
R5F21217JFP can support compact consumer-appliance control boards where a dedicated MCU manages user input, relays, indicators, and safety-related sequencing. Its 16-bit architecture and 48 KB flash are appropriate for moderate embedded code, and the 3 V to 5 V range aligns with many low-voltage control boards. Designers should include hardware watchdog behavior, defined reset states, and fail-safe defaults for actuators. The supplied data does not establish agency certification, environmental ruggedness, or exact peripheral coverage, so product-specific validation remains necessary before release.

設計ノート
Use the Renesas 48-pin LQFP footprint and keep all decoupling capacitors close to the MCU supply pins. Place the oscillator or clock components near their assigned pins and provide a short, direct return path to the ground plane. Because the supplied data does not include the complete pinout or recommended land pattern, verify both against the current manufacturer package drawing before fabrication.
Design the 3 V to 5 V supply with local bulk and high-frequency bypassing, and verify the regulator's startup, load-current, and transient requirements against the complete electrical specifications. Keep switching-regulator nodes and high-current actuator traces away from MCU supply and signal routing. The supplied data does not provide current consumption or absolute maximum ratings, so these values must be obtained before power budgeting.
Do not treat an LQFP footprint match as proof of drop-in compatibility. A replacement must also match pin functions, reset behavior, oscillator requirements, memory organization, peripheral mapping, voltage levels, and firmware expectations. The verified cross-reference search did not identify a confirmed pin-compatible replacement for R5F21217JFP, so substitution must be validated with the manufacturer pinout and device specifications.
コンプライアンス情報
The Mouser listing identifies R5F21217JFP as Pb-free. RoHS, REACH, AEC-Q100, halogen-free status, and conflict-minerals status are not explicitly stated in the supplied verified data.
