R5F64179PFD - 32-Bit 1MB Flash 50MHz MCU | Renesas
部品番号: R5F64179PFD ✓ 生産中R5F64179PFD 概要
A microcontroller is a semiconductor integrated circuit that executes firmware, controls peripherals, and coordinates digital system behavior. The R32C/100 family is a Renesas MCU family whose naming places the R5F64179 part in the high-pin-count, Flash-equipped segment of the M16C-compatible portfolio. This family relationship matters because software, peripheral resources, and development tooling can often be reused across related members, although each exact device must still be checked for peripheral, memory, timing, and package differences.
The verified listing highlights three principal characteristics: 16/32-bit processing, 1 MB of Flash organized as 1M x 8, and operation up to 50 MHz. A separate technical listing states a 16 MHz clock speed, creating a source discrepancy that should be resolved against the exact revision of the manufacturer datasheet. The 144-LFQFP package provides 144 leads on a 20 x 20 mm body with a stated 0.50 mm pitch, supporting dense PCB layouts where a smaller package cannot provide enough external I/O.
The 1 MB Flash allocation is the most significant storage characteristic in the verified data. It gives embedded software substantially more room for code, constants, calibration data, and field-upgrade logic than a small-memory MCU, while the 144-pin package exposes a comparatively large number of signal connections for peripherals and board-level interfaces. Exact RAM size, timer resources, serial interfaces, ADC capabilities, pin multiplexing, and interrupt structure are not present in the supplied verified records and therefore should not be inferred from the family name alone.
Typical uses include industrial automation controllers, embedded equipment, motor and power-system controllers, communication gateways, and compact consumer appliances. The combination of 1 MB Flash, a high-pin-count package, and a 3 V to 5.5 V family supply range can suit systems that need substantial firmware storage and numerous external connections. Designers should verify the exact peripheral mix, electrical limits, and timing requirements before selecting the MCU for a new PCB.
A key design consideration is decoupling. Place the device's supply and ground connections directly to the nearest plane with short, low-inductance paths, and populate local bypass capacitors according to the exact manufacturer requirements. The 0.50 mm lead pitch is also demanding during manual inspection and rework, so a fine-pitch assembly process and careful footprint verification are important for reliable production.
This page consolidates verified distributor specifications, ordering information, package details, sourcing links, and source-aware engineering guidance. It also highlights the unresolved 16 MHz versus 50 MHz listing discrepancy instead of presenting an unverified value, helping engineers identify what must be confirmed in the official R5F64179PFD documentation before schematic release.

主な用途
R5F64179PFD の用途: 6 件s: Industrial Automation Controller, Embedded Equipment Controller, Motor and Power-System Control, Communication Gateway, Consumer Appliance Control, Data Acquisition and Monitoring.
Industrial Automation Controller
The R5F64179PFD fits industrial automation controllers that need substantial embedded firmware and a high-pin-count controller package. Its verified 1 MB Flash capacity provides room for motion logic, communications routines, diagnostics, and configuration data, while the 144-LFQFP package offers many physical connections for digital I/O and external interfaces. The verified family supply range of 3 V to 5.5 V is useful for preliminary rail planning in 5 V industrial control boards. Before finalizing the design, verify the exact 50 MHz versus 16 MHz source discrepancy, peripheral inventory, and electrical limits in the official documentation.
おすすめ
Embedded Equipment Controller
The R5F64179PFD is suitable for embedded equipment controllers whose firmware includes sequencing, user-interface handling, fault management, and communication stacks. The verified 1M x 8 Flash organization gives the application substantially more code and data capacity than small-memory MCUs, while the 16/32-bit R32C/100 architecture supports a broad control workload. Its 144-lead package is useful when the controller must connect numerous sensors, relays, and external interface circuits. Exact RAM, I/O ratings, and peripheral functions remain unverified in the supplied excerpts and should be checked before schematic approval.
おすすめ
Motor and Power-System Control
The R5F64179PFD can serve as the central controller in a motor-control or power-system module where firmware complexity and external signal connections justify a 144-pin device. Its verified 1 MB Flash allows storage of control algorithms, protection tables, calibration coefficients, and fault logs, while the 3 V to 5.5 V listed supply range supports preliminary design around a regulated 5 V rail. The high lead count can simplify access to multiple control outputs and communication signals. Designers must confirm timer, PWM, ADC, interrupt, and electrical-drive specifications because those details are not present in the supplied verified data.
おすすめ
Communication Gateway
The R5F64179PFD is a plausible controller for an industrial communication gateway that must retain protocol firmware, routing tables, diagnostics, and configuration data. The verified 1 MB Flash capacity provides considerably more program storage than minimal communication MCUs, and the 144-LFQFP footprint offers many pins for serial interfaces and status signaling. The 16/32-bit R32C/100 family designation provides a useful basis for software planning. Before selecting the exact device, verify which UART, CAN, USB, or other interfaces are present, along with RAM, protocol timing, and peripheral multiplexing, because the supplied excerpts do not confirm them.
おすすめ
Consumer Appliance Control
The R5F64179PFD can be used in a consumer appliance controller when the product combines multiple actuators, user controls, diagnostic logic, and field-update requirements. The verified 1 MB Flash supports a larger embedded application than a very small code-space MCU, while the 144-LFQFP package exposes many I/O positions for displays, switches, sensors, and drivers. The listed 3 V to 5.5 V operating range aligns with preliminary designs built around regulated 5 V or appropriately designed 3.3 V rails. Confirm electrical limits, temperature range, ADC performance, and exact package pin functions in the manufacturer datasheet before release.
おすすめ
Data Acquisition and Monitoring
The R5F64179PFD is relevant to compact data-acquisition and monitoring equipment that must store acquisition firmware, calibration data, event logs, and communication code. Its verified 1 MB Flash provides meaningful code and constant storage, and the 144-pin package offers enough physical connections for sensor inputs, status indicators, and external converters. The 16/32-bit processing designation is appropriate for coordinating multi-channel sampling and local control. However, ADC resolution, sampling performance, timer channels, RAM, and I/O logic levels are not included in the supplied records, so engineers must verify them against the exact datasheet before selecting this MCU.

設計ノート
Treat the R5F64179PFD as a fine-pitch 144-LFQFP design with a verified 0.50 mm lead pitch. Confirm the manufacturer land pattern, solder-mask clearance, paste volume, and courtyard before releasing the PCB because generic LQFP libraries can differ in pad length, toe extension, and exposed thermal behavior. Use a pick-and-place process capable of handling 0.50 mm leads, and conduct inspection under magnification to detect bridging across closely spaced pins.
Plan a stable supply rail within the verified 3 V to 5.5 V family range, but verify the exact R5F64179PFD operating and startup conditions before committing the power architecture. Place local supply bypass capacitors close to the device's power and ground pins, use short return paths, and keep high-current switching loops away from sensitive signal traces. The supplied excerpts do not provide the exact recommended capacitance, ESR, regulator type, or pin-level power requirements.
The 144-lead package provides many external connections, so group sensitive inputs, communications, and power interfaces according to the verified pin table rather than assigning functions from family assumptions. Preserve continuous ground references beneath the device where the package and board stack-up permit, minimize stubs on high-speed nets, and isolate switching nodes from measurement inputs. Obtain the official pin and package drawings before finalizing fan-out or impedance-controlled routing.
Do not assume that every R5F64179 ordering suffix has identical temperature, packing, qualification, or marking requirements. The supplied sources list R5F64179PFD#2B and R5F64179PFD#UB without a complete suffix-definition table. In addition, verified clock information conflicts between 16 MHz and 50 MHz. Resolve both issues against the exact ordering code and current manufacturer documentation before programming production parts.
コンプライアンス情報
The supplied verified excerpts do not state part-specific RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The lifecycle stage is stated as Active, but that does not establish regulatory qualification.
