R5F72544RKBG - 32-Bit SuperH RISC MCU | Renesas Electronics
料号： R5F72544RKBG ✗ 停产R5F72544RKBG 概述
A microcontroller is an embedded processing component that integrates a processor core, memory, and programmable peripherals into one semiconductor device. Within the electronics hierarchy, an MCU is a microprocessor-based embedded controller, an integrated circuit, and a semiconductor. Unlike a general-purpose host processor, an MCU is normally designed around deterministic control tasks, compact firmware, low-cost hardware, and direct interaction with sensors, actuators, communications links, and industrial interfaces. The SuperH RISC architecture identifies the processor family associated with the R5F72544RKBG.
The verified 32-bit SuperH RISC designation is the central confirmed technical characteristic. A 32-bit architecture provides a 32-bit data path and is commonly associated with control workloads requiring more arithmetic and addressing capability than an 8-bit MCU. The supplied sources do not establish the instruction throughput, operating frequency, internal flash, SRAM, timer resources, serial interfaces, or analog peripherals, so those specifications should be obtained from the manufacturer documentation before firmware timing or resource planning.
Renesas Electronics Corporation is the manufacturer named in the distributor records, while several authorized-marketplace listings identify the part as a microcontroller from the SH7254R product family. The related manufacturer page for SH7254R describes the family as offering high-performance system functionality at lower system cost. The same-family association is useful for architecture-level orientation, but it must not be treated as proof that every parameter of a neighboring ordering code is identical to R5F72544RKBG.
Potential uses include real-time industrial control, power conversion control, aerospace-oriented embedded control, motor and actuator management, and communication-enabled equipment. These are application categories rather than claims that a particular peripheral is present in the exact R5F72544RKBG device. Firmware and schematic decisions require the exact pinout, electrical limits, clock configuration, peripheral matrix, and operating conditions from the datasheet and hardware manual corresponding to this ordering code.
The main design consideration is to avoid treating another SH7254R ordering code as automatically interchangeable. The package suffix, terminal arrangement, exposed-pad requirements, pin multiplexing, and electrical characteristics have not been established by the supplied results. Before a PCB or production substitution, compare the exact R5F72544RKBG data against the candidate device and validate programming, startup, clock, reset, and power-supply behavior on hardware.
This page consolidates the verified distributor identity, family context, sourcing links, aerospace application reference, honest data gaps, and engineering-selection guidance. It adds practical information beyond a raw distributor listing while avoiding unverified package, memory, timing, pinout, and pricing claims.

典型应用
R5F72544RKBG 适用于 6 应用s: Real-Time Power Control, Industrial Automation Control, Aerospace-Oriented Embedded Control, Motor and Actuator Management, Communication-Enabled Control Equipment, Instrumentation and Measurement.
Real-Time Power Control
The 32-bit SuperH RISC architecture makes the R5F72544RKBG a candidate for embedded real-time control systems, although its exact timing peripherals are not disclosed in the supplied results. A related manufacturer page specifically associates R5F72544RKBGV#US with real-time power control in aerospace applications. An engineer evaluating R5F72544RKBG should therefore verify timer width, PWM channels, update latency, interrupt behavior, and deterministic execution before committing to it. The exact datasheet is necessary to confirm that the device can meet switching-loop deadlines, provide redundant control paths where required, and operate within the intended environmental limits.
Industrial Automation Control
The R5F72544RKBG can be evaluated for industrial automation controllers because it is a 32-bit embedded MCU with the SuperH RISC architecture. Such systems commonly coordinate sensors, digital I/O, communication links, and actuator commands under a deterministic control schedule. The supplied evidence does not confirm the target’s serial interfaces, analog channels, digital I/O count, or operating-temperature range, so these functions cannot be assumed. Selection should follow a complete comparison of cycle time, peripheral resources, software-toolchain support, and long-term availability. A hardware proof of concept should verify startup, reset behavior, clock tolerance, and communication timing before production release.
Aerospace-Oriented Embedded Control
Renesas markets the closely identified R5F72544RKBGV#US as an automotive MCU that can also serve aerospace real-time power-control applications. That application reference makes the SH7254R family relevant for aerospace-oriented engineering studies, but it does not prove that every qualification or environmental attribute applies to R5F72544RKBG. Engineers must request the exact ordering-code datasheet, reliability information, traceability records, and applicable design-assurance evidence. The architecture should be accepted only after checking radiation-related assumptions, operating-temperature limits, watchdog behavior, memory integrity features, and the qualification scope stated by Renesas.
Motor and Actuator Management
The 32-bit R5F72544RKBG is architecturally suitable for evaluating motor and actuator management functions that require more computation than a simple 8-bit controller. Potential tasks include command decoding, fault monitoring, and coordinated output sequencing. However, the verified records do not identify PWM modules, encoder interfaces, capture units, or operating limits for R5F72544RKBG, so the device cannot yet be assigned to a motor-control topology. Review the exact pinout and peripheral matrix, calculate required control-loop timing, and confirm whether external drivers are needed. Prototype testing should cover startup transients, overload behavior, and safe output states.
Communication-Enabled Control Equipment
As a 32-bit embedded microcontroller, the R5F72544RKBG may fit control equipment that combines local processing with external communications, provided the exact serial and peripheral resources are confirmed. The supplied evidence does not list UART, SPI, I2C, CAN, USB, Ethernet, or other interfaces, so no particular protocol should be assigned to this part. System planning should start from the required baud rate, frame format, bus concurrency, isolation requirements, and software stack. Once the datasheet is reviewed, engineers can determine whether external interface controllers are needed and whether the MCU has sufficient processing headroom for protocol handling and real-time tasks.
Instrumentation and Measurement
The R5F72544RKBG can be considered for embedded instrumentation roles because it is a 32-bit SuperH RISC microcontroller capable of handling more complex control and data-processing logic than an 8-bit MCU. The verified data does not disclose analog-converter inputs, timer accuracy, memory capacity, or interface timing, which are decisive factors for measurement equipment. An engineering assessment should compare required acquisition latency, calibration approach, data-transfer bandwidth, and display or storage requirements against the exact datasheet. Firmware architecture should also account for deterministic sampling, error handling, and watchdog coverage. Prototype measurements must demonstrate accuracy and stability under the intended noise, temperature, and supply conditions.

设计说明
Do not substitute a superficially similar R5F72544 ordering code without checking the exact package drawing and terminal assignment. The verified evidence associates R5F72544RKBG with the SH7254R family and separately lists R5F72544RKBGV#US, but it does not establish that their packages, exposed pads, pin multiplexing, or electrical limits are identical. Download the exact datasheet, compare the ordering-information table, and verify every power, ground, reset, clock, and I/O connection before approving a replacement.
Plan the power tree only after confirming the R5F72544RKBG operating-voltage range, absolute maximum ratings, internal regulator topology, and I/O supply domains. Those values are absent from the supplied records and must not be inferred from the 32-bit or SuperH RISC labels. Decoupling, startup sequencing, reset behavior, and brownout handling should follow the exact Renesas guidance. The power design should also provide margin for connected loads without exceeding the device's verified current and thermal limits.
Reserve the PCB land pattern and pin escape only after obtaining the package drawing tied to the RKBG suffix. Verify body dimensions, lead pitch, pin numbering direction, exposed-pad dimensions, and thermal-via recommendations from the manufacturer document. Because the verified results do not disclose those values, an inferred footprint can create assembly, soldering, or EMI problems even when the device family and pin count appear similar. Have the final land pattern cross-checked against the approved datasheet revision.
Confirm clock, memory, peripheral, and toolchain availability for the exact ordering code before committing the design. The supplied evidence confirms a 32-bit SuperH RISC microcontroller but omits maximum operating frequency, flash, SRAM, timer resources, and serial interfaces. These omissions affect interrupt latency, firmware sizing, protocol implementation, and end-of-line test coverage. Use the current Renesas datasheet, hardware manual, and product page to establish every resource needed by the application.
合规信息
RoHS compliance is identified by the verified JLCPCB product result. Other compliance attributes were not established by the supplied evidence and remain unknown. The manufacturer application page concerns the related R5F72544RKBGV#US and does not independently qualify the exact target ordering code.
