R5F21113FP#U0 - 16-Bit 20MHz R8C MCU | Renesas
Teilenummer: R5F21113FP#U0 ✓ AktivR5F21113FP#U0 Übersicht
A microcontroller is an integrated circuit containing a processor core, program memory, data memory, peripherals, and I/O on one device. The R8C architecture belongs to the 16-bit microcontroller class and combines relatively high instruction efficiency with a compact instruction set suited to embedded products. Within the broader semiconductor hierarchy, the R5F21113FP#U0 is a general-purpose embedded processor and system-on-chip component rather than a discrete logic or analog device.
Key characteristics include a 20 MHz maximum operating frequency, 12 KB of flash program memory, a 3 V to 5 V supply range, and a 32-pin plastic molded LQFP package. The flash-based program architecture allows firmware to be stored directly in the MCU rather than in an external memory device, helping reduce total system complexity. The manufacturer describes the part within its R8C/11 family of 16-bit microcontrollers with R8C CPU cores.
The R8C/1x/11 core is intended for applications that require efficient 16-bit processing without the cost and complexity of a high-end application processor. Its compact LQFP footprint remains compatible with conventional surface-mount assembly and reflow processes, while the 7 x 7 mm body allows placement alongside analog, power, communication, and sensing components on a densely populated control board.
Typical uses include industrial control modules, appliance controllers, measurement equipment, motor-control peripherals, sensor-hub designs, and compact consumer products. For battery-operated or precision analog systems, designers should confirm supply voltage, peripheral mix, clock requirements, and power-consumption targets against the manufacturer datasheet before committing the MCU to a board architecture.
The primary design consideration is firmware portability across the R8C/1x/11 family. Because package suffix codes can identify different temperature, packaging, or ordering options, engineers should compare the exact MPN, pin assignments, peripheral availability, and memory configuration rather than assuming that every family member has identical behavior.
This page organizes the principal specifications, sourcing information, family-level drop-in options, application guidance, and practical design notes. It is intended to help engineers identify whether the R5F21113FP#U0 matches a 16-bit embedded-control requirement before schematic capture and PCB layout begin.

Typische Anwendungen
R5F21113FP#U0 ist geeignet für 6 Anwendungs: Industrial Control Module, Appliance and Home Equipment Controller, Sensor Hub and Data Aggregator, Measurement and Instrumentation Front End, Battery-Powered Portable Device, Communication Interface Controller.
Industrial Control Module
The R5F21113FP#U0 fits compact industrial control modules that coordinate sensors, discrete outputs, and serial peripherals from a single controller. Its 16-bit R8C/1x/11 core operates at up to 20 MHz, providing enough instruction throughput for sequencing, signal conditioning, and supervisory logic without an external processor. The 12 KB flash allocation supports a dedicated control program, while the 32-LQFP 7 x 7 mm footprint conserves board area beside power regulation and interface circuits. Confirm operating-temperature limits and peripheral assignments in the manufacturer datasheet before deploying the design in an industrial enclosure.
Empfohlen
Appliance and Home Equipment Controller
Home appliances and compact equipment benefit from the R5F21113FP#U0 when a dedicated 16-bit controller is preferred over a general application processor. The device directly stores its operating program in 12 KB of internal flash, simplifying the memory hierarchy for motor, valve, display, or sensor-control functions. Its 3 V to 5 V operating range supports common mixed-voltage systems, and the 32-LQFP package is practical for automated assembly. Designers should budget flash for diagnostics, boot handling, and future firmware revisions, then confirm the final pin mux against the datasheet.
Empfohlen
Sensor Hub and Data Aggregator
The R5F21113FP#U0 can serve as the central controller in a sensor hub that gathers switch, digital-interface, or low-speed analog-derived inputs and forwards processed data. Its 20 MHz R8C performance allows firmware to combine measurement conditioning, filtering, and protocol framing within one 12 KB program budget. A 3 V to 5 V operating range simplifies interfacing with common sensor and logic components, while the 32-LQFP body keeps the controller small. Peripheral availability, ADC characteristics, and timer resolution should be reviewed before assigning analog-intensive functions to this device.
Empfohlen
Measurement and Instrumentation Front End
The R5F21113FP#U0 is appropriate for instrumentation front ends that require local sequencing, calibration handling, and communication alongside an external converter. The 16-bit R8C/1x/11 core can manage configuration sequences and produce command or measurement packets at up to 20 MHz, while 12 KB of flash accommodates the control application and protocol layer. The compact LQFP package supports high-density analog boards where space is limited. For precision measurement, retain analog filtering and reference design outside the MCU and verify converter timing against the datasheet.
Empfohlen
Battery-Powered Portable Device
A portable instrument or low-duty-cycle controller can use the R5F21113FP#U0 when low-power operation and deterministic 16-bit control are priorities. The device runs from 3 V to 5 V and includes its program in 12 KB of on-chip flash, eliminating a parallel external program-memory device in designs where that is acceptable. Firmware can use timers and internal peripherals to reduce continuous processor activity, although the final sleep currents and wake-up times must be taken from the manufacturer documentation.

Empfohlen
Communication Interface Controller
The R5F21113FP#U0 can control a protocol bridge or distributed communications node that must combine serial handling with local configuration logic. At up to 20 MHz, the R8C/1x/11 core supports interrupt-driven UART or timer-based framing routines, and the 12 KB flash region holds the protocol stack and application state machine. Its 32-LQFP 7 x 7 mm package leaves room for a transceiver, connector, and power stage on a compact board. Confirm the electrical levels, baud-rate support, and peripheral multiplexing with the datasheet before layout.

Wichtigste Unterscheidungsmerkmale
- Matching 20 MHz performance and flash configuration (vs. R5F21113FP#W4)

- R8C ecosystem continuity (vs. R5F21113FP#W4)
Designhinweise
Reserve the LQFP land pattern and thermal or ground pads shown in the manufacturer package drawing before committing the board outline. Place decoupling capacitors close to each supply pin and route high-current return paths away from sensitive control traces. Because the exact pin-multiplexing options are defined by the datasheet, assign nets from the signal table rather than from a generic LQFP template.
Design the supply around the documented 3 V to 5 V operating range and allow for startup and transient margin at both limits. The R8C/1x/11 core can execute at up to 20 MHz, so clock settings, peripheral clocks, and brownout behavior must be coordinated before power sequencing is finalized. Verify the configured regulator output against the MCU's minimum and maximum supply requirements.
Do not assume that every R8C/1x/11 ordering code is interchangeable. The R5F21113FP#W4 shares the 32-LQFP format and headline 20 MHz, 12 KB configuration with the R5F21113FP#U0, but suffix functions, temperature conditions, and purchasing conditions must be checked. Also confirm flash usage against the complete firmware image, including bootloader, calibration data, and field-update logic.
Compliance-Informationen
