R5F21163SP#U0 - 16-Bit R8C MCU, 12KB Flash | Renesas
MPN: R5F21163SP#U0 ✗ پایان تولیدR5F21163SP#U0 نمای کلی
A microcontroller is a programmable semiconductor that integrates a CPU core, program memory, data memory, and peripherals into one compact device. The R8C/Tiny architecture belongs to the broader microcontroller hierarchy, where a general-purpose processor core is combined with embedded resources for control-oriented products. Its 16-bit architecture and compact package make the R5F21163SP#U0 suitable for industrial equipment, appliance controls, sensor interfaces, and compact automation modules.
The R5F21163SP#U0 combines a 16-bit CPU core, 12 KB flash program memory, and a 3 V/5 V operating class in a 20-pin LSSOP package. The 2.7 V to 5.5 V operating range allows operation across common 3.3 V and 5 V systems. A lead-free 20-SSOP form factor also supports conventional surface-mount manufacturing and compact PCB layouts.
Renesas describes the device as using sophisticated instructions developed for high instruction efficiency. The R8C/Tiny Series core is suitable for embedded products that need more control than a simple logic device but do not require the resources of a general-purpose application processor. The silicon-gate CMOS process provides the manufacturing foundation for the integrated low-power control functions.
Typical applications include industrial control panels, motor and machine controllers, building equipment, appliance interfaces, and compact sensor nodes. The 20-pin package limits external connectivity, so projects requiring many I/O pins, high-speed communications, or large memory capacities should be evaluated against other members of the Renesas portfolio. The R8C/16 Group is positioned for continued support of existing designs rather than broad adoption in new projects.
When designing around this MCU, preserve the voltage limits of every connected signal and decouple each applicable supply rail close to the device. Review the pin-description table in the manufacturer datasheet before assigning board functions because package availability alone does not establish pin compatibility. Firmware, peripheral configuration, startup behavior, and software tools should also be reviewed against the target revision.
This product page combines the manufacturer’s device description with focused engineering guidance for sourcing, PCB implementation, lifecycle planning, and family selection. It also distinguishes true pin-compatible options from devices that merely share a similar package or memory size, helping engineers avoid replacements that require firmware, board, or connector changes.

کاربردهای معمول
R5F21163SP#U0 مناسب است برای 6 کاربردs: Industrial Control Module, Appliance Control Board, Sensor Interface and Data Logger, Legacy Equipment Maintenance, Compact Automation Controller, Embedded Timing and Sequencer.
Industrial Control Module
The R5F21163SP#U0 fits compact industrial control modules that require a 16-bit R8C/Tiny core, 12 KB of flash, and operation across 2.7 V to 5.5 V without the footprint overhead of a larger MCU package. Place the controller between a low-voltage supply and discrete sensors, relays, or actuators, then map each peripheral function through the datasheet pin table. The 20-pin LSSOP supports space-constrained control boards, while its 16-bit instruction-oriented core provides more processing capability than simple fixed-function logic. Because the R8C/16 Group is limited to previously adopted designs, use this part primarily when maintaining an established control platform rather than beginning an unrestricted new platform.
پیشنهادی
Appliance Control Board
The R5F21163SP#U0 can serve as the central controller in a compact appliance board that combines button inputs, indicators, and simple motor or heater control. Its 12 KB flash capacity provides room for embedded application code, while the R8C/Tiny Series core is designed around instruction efficiency for control-oriented workloads. A 3.3 V or 5 V system architecture aligns with the stated 2.7 V to 5.5 V operating range, subject to the detailed electrical limits for each pin. The 20-pin LSSOP also reduces board area compared with many controller packages. Firmware should include suitable startup behavior, fault handling, and output-state defaults for appliance safety requirements.
پیشنهادی
Sensor Interface and Data Logger
The R5F21163SP#U0 is suitable for a compact sensor node that samples external signals, applies control logic, and stores operational information. Its 16-bit R8C/Tiny core is appropriate for instruction-efficient embedded processing, and the 12 KB flash provides a defined program-memory budget for acquisition routines and data formatting. The 2.7 V to 5.5 V range supports common embedded supply systems and simplifies sensing experiments performed at either 3.3 V or 5 V. The 20-LSSOP footprint helps preserve board area in distributed instrumentation. Before implementation, confirm the required analog, timer, serial, and port resources against the exact manufacturer pin table because the limited pin count may require careful multiplexing.
پیشنهادی
Legacy Equipment Maintenance
The R5F21163SP#U0 is especially relevant for maintenance of legacy equipment built around the R8C/16 platform. Its 16-bit R8C/Tiny architecture, 12 KB flash configuration, and 20-pin LSSOP package can support a like-for-like service strategy when the installed board, firmware organization, and peripheral assignments already depend on this device. Renesas states that the R8C/16 Group is supported for customers that previously adopted it, making continuity particularly relevant for industrial, appliance, and automation systems with long service lives. Engineers should still validate memory, pin, and clock differences against the original device and consider a last-time-buy plan where continued production support is required.
پیشنهادی
Compact Automation Controller
The R5F21163SP#U0 can be integrated into a compact automation controller that coordinates discrete inputs and outputs, runs sequencing logic, and handles local machine-state decisions. Its R8C/Tiny Series core emphasizes efficient embedded instructions, while the 12 KB flash capacity is appropriate for bounded control logic rather than a large graphical or network-intensive application. The 20-pin LSSOP package makes it practical for small controller boards, and the 2.7 V to 5.5 V operating range supports both 3.3 V and 5 V implementations. Confirm the required timer channels, communication interface, reset behavior, and I/O levels in the manufacturer datasheet before finalizing the board, especially for safety-related outputs.
پیشنهادی
Embedded Timing and Sequencer
The R5F21163SP#U0 can be used in an embedded timing or sequencing subsystem where a deterministic control routine coordinates multiple outputs and reacts to external events. The 16-bit R8C/Tiny Series core is suited to instruction-efficient machine-control logic, and the integrated 12 KB flash provides a constrained but practical code budget. Its compact 20-pin LSSOP outline leaves board space for power conversion, signal conditioning, or communications, while the 3 V/5 V supply class supports conventional industrial logic ecosystems. The design must account for the limited number of pins, peripheral multiplexing, startup pin states, and the need for deterministic timing. Use the manufacturer timing and peripheral documentation to configure interrupts and timers correctly.

یادداشت‌های طراحی
Route the 20-SSOP footprint exactly as defined by the manufacturer land pattern and preserve clearance around exposed board features. Place required decoupling capacitors close to their corresponding supply pins, with the shortest practical return path to the device ground reference. Because the package has only 20 pins, review multiplexed functions early in schematic design; adding a peripheral later may force a pin conflict or a board respin. Use the pin-description table in the manufacturer datasheet as the controlling assignment document.
Design the supply for the R5F21163SP#U0 within its stated 2.7 V to 5.5 V operating range, and do not infer individual input or output voltage tolerances from that system range. Confirm each supply, reset, and I/O pin against the electrical-characteristics table. Keep power-source transitions and externally driven signals away from the MCU supply limits. If the board includes relays, heaters, motors, or inductive loads, isolate their switching and transients from the controller rather than relying on the MCU package alone for protection.
Do not treat the 20-SSOP outline as proof that any R5F2116x device is pin-to-pin interchangeable. Compare pin names, peripheral multiplexing, memory organization, interrupt behavior, clock requirements, reset inputs, and programming procedure across the exact manufacturer datasheets. Also preserve the distinction between R5F21163SP and the full R5F21163SP#U0 order code. A successful schematic substitution still requires a clean software build, peripheral smoke test, reset test, and review of every changed output state.
Provide stable power before enabling normal operation and follow the manufacturer’s reset and startup sequence. The controller’s digital outputs and port states during reset can affect connected equipment, so external hardware should enforce safe actuator states rather than depend solely on firmware defaults. For maintenance projects, validate brownout, power-loss, and watchdog behavior at the system level. These checks are especially important when retaining an R8C/16-based design because changing the MCU family can alter startup latency and register behavior.
