R5F74504KBG 概述
A microcontroller is a programmable system-on-chip that integrates a CPU core, memory, peripherals, and interface functions into one package. The SH-4A belongs to the RISC microcontroller hierarchy and combines a compact instruction set with a high clock rate. For the R5F74504KBG, this architecture supports demanding real-time control tasks while retaining a broad embedded peripheral integration.
The verified product information identifies a maximum operating frequency of 240 MHz and performance above 432 MIPS. Single- and double-precision floating-point support accelerates mathematical workloads without requiring a separate numerical processor. This makes the MCU relevant to applications involving signal processing, multimedia data handling, graphics, control loops, and connected embedded equipment. The SH7450 and SH7451 groups share the R5F74504KBG family designation.
Renesas positions the SH7450 and SH7451 devices as high-performance RISC microcontrollers. Their floating-point capabilities provide a clear distinction from fixed-point-only controllers, while the 240 MHz operating point supports workloads with demanding instruction throughput. Exact memory configuration, peripheral inventory, electrical limits, and operating-temperature boundaries must be confirmed in the manufacturer datasheet before a design is released.
Typical application areas include industrial automation, network-connected embedded control, multimedia terminals, audio and signal processing, consumer equipment, and communications infrastructure. The processor performance is useful where deterministic control and floating-point computation must coexist, although firmware and system-level timing still require careful validation.
Design planning should begin with the manufacturer pin assignment, supported memory interfaces, peripheral multiplexing, and clock requirements. Because this is a 292-pin FBGA device, careful PCB escape routing, controlled-impedance design, and adequate via and fanout planning are necessary. This page synthesizes verified family specifications, sourcing links, application guidance, and qualification limits for faster engineering review.

典型应用
R5F74504KBG 适用于 6 应用s: Industrial Automation and Machine Control, Multimedia and Embedded Signal Processing, Communications and Network-Connected Equipment, Audio and Float-Point Processing, Automotive and Robust Embedded Control, High-Speed Data Acquisition.
Industrial Automation and Machine Control
The R5F74504KBG fits high-complexity machine-control functions that need deterministic 32-bit computation alongside floating-point math. Its SH-4A core operates up to 240 MHz and exceeds 432 MIPS, providing useful headroom for motion algorithms, sensor conditioning, and supervisory logic in one embedded controller. The floating-point support can accelerate calculations that would otherwise consume substantial cycles on a fixed-point MCU. Before schematic release, verify timer, communications, and I/O requirements in the manufacturer datasheet, and validate the exact R5F74504KBG temperature and voltage grades for the target enclosure.
推荐
Multimedia and Embedded Signal Processing
The R5F74504KBG is a strong candidate for multimedia endpoints that combine real-time control with numerical workloads. Its 240 MHz SH-4A core delivers more than 432 MIPS, while single- and double-precision floating-point support can accelerate filtering, transforms, and signal calculations. This reduces the need for separate arithmetic hardware when the software architecture can map effectively onto the instruction set. The 292-pin FBGA also provides extensive interconnection, but it demands a fine-pitch board design and careful high-speed routing. Confirm the available display, audio, DMA, memory, and external-interface resources before selecting the device.
推荐
Communications and Network-Connected Equipment
The R5F74504KBG can serve as the processing core in communications equipment requiring more throughput than a basic control MCU. The 240 MHz SH-4A architecture and floating-point capability support protocol processing, packet handling, and control-plane work in a single embedded design. Its large 292-pin FBGA offers many external signals for memory and peripherals, but the fine-pitch package and potential high-speed interfaces require careful layer planning. The verified snippets do not identify the complete networking peripheral set, so engineers should confirm Ethernet or other interface support, protocol acceleration, memory bandwidth, and electrical limits in the Renesas documentation before schematic release.
推荐
Audio and Float-Point Processing
The R5F74504KBG is suitable for audio-related embedded functions because its SH-4A core supports single- and double-precision floating-point arithmetic. At more than 432 MIPS, the processor can combine real-time control with filtering, mixing, or acoustic processing while avoiding a separate floating-point coprocessor. The architecture is especially attractive where product control, communication, and signal handling share one device. The supplied data does not enumerate the audio peripherals, so users must check the datasheet for DMA channels, memory interfaces, sample-rate support, and clocking. Firmware should also be profiled against the required filter and control workload.
推荐
Automotive and Robust Embedded Control
The R5F74504KBG can be evaluated for vehicle or other robust embedded-control platforms where high computational performance and floating-point support are valuable. Its 240 MHz SH-4A core exceeds 432 MIPS, enabling sophisticated control, diagnostics, and signal algorithms within a single microcontroller. However, automotive deployment cannot be inferred from processor performance alone. The verified snippets do not provide the operating-temperature grade, AEC-Q100 status, functional-safety rating, voltage range, or automotive qualification. Those attributes must be confirmed in current Renesas product documentation before the MCU is used in safety-relevant or production automotive equipment.
推荐
High-Speed Data Acquisition
The R5F74504KBG is a candidate for embedded acquisition systems that need real-time control and numerical processing on the same MCU. Its SH-4A core reaches 240 MHz and exceeds 432 MIPS, providing processing capacity for sensor sampling, scaling, filtering, and data preparation. The 292-pin FBGA can expose substantial memory and peripheral connectivity, although the supplied data does not confirm converter interfaces, DMA resources, or external memory specifications. Engineers should establish signal bandwidth, required latency, memory bandwidth, and package-routing constraints first, then verify those requirements against the manufacturer datasheet and reference designs.

选型指南
设计说明
The R5F74504KBG uses a 292-pin FBGA, so the PCB should be designed only from the official package drawing and land pattern. Confirm ball assignments, power and ground distribution, escape-routing capacity, and assembly-process requirements before layout release. Fine-pitch fanout typically benefits from blind or buried vias and multiple routing layers; however, the exact stackup and escape geometry must follow Renesas guidance rather than generic BGA assumptions.
Treat power integrity as a first-class concern for this 240 MHz, 292-pin FBGA microcontroller. Decoupling values, allowable ripple, voltage ramp requirements, and power-source topology are not present in the verified snippets and must be taken from the manufacturer datasheet. Place required bulk and high-frequency decoupling at the relevant supply balls, provide adequate return paths, and verify startup and voltage tolerance using worst-case clock, temperature, and I/O loading assumptions.
Separate clocks, high-speed memories, and communication interfaces from noisy analog or switching paths when the board architecture permits. Maintain continuous reference planes and avoid return-path discontinuities beneath the MCU and memory interfaces. Because the verified data does not enumerate all external interfaces or their signal-integrity requirements, engineers should derive topology and impedance targets from the Renesas interface specifications, then validate them through signal-integrity simulation and measurement.
Do not treat the SH7450 and SH7451 family label as proof that every member is a substitute for R5F74504KBG. Confirm exact flash capacity, RAM, peripheral availability, clock features, package, and pin assignment for the ordered variant. The verified data explicitly identifies 240 MHz operation, performance above 432 MIPS, floating-point support, and a 292-pin FBGA, but it does not establish a pin-compatible replacement or complete device-level specification set.
合规信息
The supplied search results do not provide device-specific compliance declarations. RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status remain unverified and must be confirmed from current Renesas documentation.
