R5F21133FP#U0 - 16-Bit 20MHz R8C MCU | Renesas Electronics
N.º da peça: R5F21133FP#U0 ✓ AtivoR5F21133FP#U0 Visão geral
A microcontroller is a programmable system-on-chip that integrates a CPU core, memory, peripherals, and I/O into one component. The R8C/1x/13 belongs to the R8C family of 16-bit embedded controllers, which sits within the broader hierarchy of microcontroller, embedded processor, and semiconductor products. Renesas positions the R8C/11 Group for designs already based on the family, while recommending RL78/G14 for new projects.
Key characteristics include a 16-bit CPU, a 20 MHz operating frequency, and 12 KB of flash memory. The device is identified as the R8C/1x/13 configuration and is offered in a compact 32-LQFP package measuring 7 x 7 mm. The listed operating range includes 3 V and 5 V supply operation, while one distributor specification identifies a 2.7 V to 5.5 V working range for this exact ordered device.
The R8C CPU core uses instruction-efficient embedded-control techniques intended to balance processing performance with compact code size. This makes the R5F21133FP#U0 relevant to designs requiring more control capability than an 8-bit MCU while retaining a relatively small 32-pin footprint. The flash-memory capacity provides 12 KB for firmware, constants, and configuration data.
Typical uses include industrial automation, embedded measurement equipment, appliance control, consumer-product interfaces, and compact motor or system-control modules. The 20 MHz clock rate is useful for time-critical control loops, while the 7 x 7 mm LQFP package simplifies assembly on conventional surface-mount production lines.
PCB design should preserve a clean analog and digital supply path, route oscillator and reset signals away from noisy switching nodes, and follow the package-specific land pattern in the manufacturer datasheet. Firmware migration also requires checking peripheral assignments, interrupt vectors, memory organization, and peripheral-register compatibility rather than assuming software compatibility from the family name alone.
This product page combines the exact ordering information, technical identity, sourcing workflow, and engineering considerations for R5F21133FP#U0. It helps designers separate the verified R8C/1x/13 configuration from similarly named family members before committing to a PCB or production release.

Aplicações típicas
R5F21133FP#U0 é adequado para 6 aplicaçãos: Compact Industrial Control Module, Appliance and Equipment Controller, Embedded Measurement Front End, Small Motor and Actuator Control, Consumer Device Interface Controller, Legacy R8C Platform Maintenance.
Compact Industrial Control Module
The R5F21133FP#U0 fits compact industrial-control modules that require a 16-bit processing core without the footprint of a larger microcontroller. Its 20 MHz operating frequency supports time-based control tasks, while 12 KB of flash stores control logic, calibration constants, and state-machine code. The 32-LQFP 7 x 7 mm package leaves board area for sensors, drivers, and communication hardware. Before finalizing the design, verify timer, counter, I/O, and interrupt resources in the manufacturer datasheet against the control-loop requirements.
Appliance and Equipment Controller
R5F21133FP#U0 is appropriate for appliance and equipment controllers that combine sequential logic, status monitoring, and limited local calculations. The 16-bit R8C core offers more processing capability than an 8-bit controller, while 12 KB of flash provides a defined firmware budget for nonvolatile program storage. Its 32-LQFP 7 x 7 mm package supports dense, automated surface-mount assembly. Confirm ADC, timer, serial-interface, and brownout requirements before assigning these functions because their availability is not established by the basic ordering information.
Embedded Measurement Front End
The R5F21133FP#U0 can serve as the controller for a compact measurement front end that samples sensors, applies calibration, and reports results through a local interface. A 20 MHz clock supports deterministic acquisition and filtering tasks, and the 12 KB flash capacity can hold configuration tables and control firmware. The 2.7 V to 5.5 V operating range permits integration with 3 V and 5 V system rails. The design must verify ADC resolution, sample rate, analog pin availability, and timing accuracy in the manufacturer datasheet.
Small Motor and Actuator Control
R5F21133FP#U0 is relevant to small motor and actuator controllers where a 16-bit CPU, 20 MHz clock, and compact 32-pin package are valuable. The MCU can execute state-machine and closed-loop control software while coordinating pulse-width modulation, position sensing, and fault handling. The 12 KB flash budget should be checked against the control algorithm and bootloader, while the 2.7 V to 5.5 V supply range must match the power architecture. Verify the required PWM channels, encoder inputs, timer modes, and protection functions before hardware release.
Consumer Device Interface Controller
The R5F21133FP#U0 can act as a dedicated interface and supervisory controller in a consumer device, handling buttons, indicators, local logic, and product-specific sequences. The 16-bit R8C core provides efficient instruction execution at 20 MHz, while 12 KB of flash stores the interface firmware without requiring an external program-memory device. The 32-LQFP 7 x 7 mm package supports compact board layouts. Designers should confirm UART, timer, GPIO, and reset-pin assignments and review the recommended migration path for new consumer platforms.
Legacy R8C Platform Maintenance
R5F21133FP#U0 is especially relevant to maintenance of an existing embedded platform built around the R8C/1x/13 configuration. Retaining the 20 MHz 16-bit core and 12 KB flash can simplify firmware and validation work when a redesign would add unnecessary schedule risk. The 32-LQFP 7 x 7 mm footprint also supports direct placement on compatible boards. For long-term maintenance, confirm lifecycle status, recommended migration parts, peripheral differences, and software-tool availability before standardizing continued production use.

Notas de projeto
Use the manufacturer package drawing and land pattern for the 32-LQFP 7 x 7 mm footprint, including pin-1 orientation, lead pitch, and exposed thermal-pad requirements if specified. Place decoupling capacitors close to the power pins and provide a short, low-impedance ground connection. Do not infer whether the center pad is electrically connected or thermally bonded until that detail is confirmed in the package drawing.
Design the supply rail for the documented 2.7 V to 5.5 V operating range, including startup and transient conditions rather than only the nominal 3 V or 5 V level. Confirm which pins supply the processor core, I/O voltage, and reset circuitry. Keep noisy switching nodes and inductors away from clock and sensitive input routing, and validate brownout behavior before using a supply rail that can sag during load changes.
Do not treat every R8C-family device as firmware-compatible with R5F21133FP#U0. Compare the memory map, interrupt-vector table, peripheral registers, port configuration, clock settings, startup sequence, and package pins. Renesas identifies the R8C/11 Group for customers already using the family and recommends RL78/G14 for new designs, making platform strategy an important qualification item before a new product release.
Route oscillator traces and reset inputs away from high-current switching nodes and noisy digital signals. Follow the manufacturer's guidance for oscillator load capacitance and startup layout, and keep programmed or externally driven signal pins accessible for production programming and validation. Where unused pins are present, apply the termination shown in the pin-description table rather than assuming every unused pin may be left completely unconnected.
