R5F51308ADFN#30 - RX130 32-bit 32MHz MCU 512KB Flash | Renesas
MPN： R5F51308ADFN#30 ✓ 啟用中R5F51308ADFN#30 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (flash), volatile working memory (RAM), and a wide range of peripheral interfaces such as ADC, timers, communication controllers, and capacitive-touch hardware. The RX130 sits inside the broader Renesas RX family (RX100/RX200/RX600/RX700) and is positioned as the cost-optimized, ultra-low-power entry tier with on-chip touch sensing. LDOs, op-amps, and reset supervisors are typically placed around the RX130 to build a complete power-tree for human-machine interface (HMI), home appliance, and industrial-sensor designs.
Key features include up to 36 channels of capacitive touch sensing with improved noise immunity, sensitivity, and water resistance versus previous RX touch generation, a 12-bit A/D converter, a D/A converter, a real-time clock (RTC), IEC60730 compliance for appliance-safety code libraries, and up to 6 communication channels. The wide 1.8 V to 5.5 V supply range allows direct connection to 5 V sensors and human-machine interface panels without level shifters. An integrated RTC and low-power modes make standby power budgets achievable for battery-operated appliances.
The RXv1 core is paired with single-precision FPU hardware support and tightly-coupled flash that supports zero-wait-state execution at 32 MHz, giving 50 DMIPS performance suitable for user-interface controllers, sensor fusion, and small protocol stacks. The capacitive-touch peripheral runs autonomously from the CPU, leaving the core free for application logic and reducing interrupt load in noisy environments. Hardware IEC60730 class-B support accelerates functional-safety certification for white goods.
Typical applications include home appliance user interfaces with touch keys, industrial control panels, battery-powered sensor nodes, building automation keypads, and small motor-control boards that need ADC plus timer resources on a single 5 V rail. The 80-pin LFQFP exposes ample GPIO for parallel displays, button matrices, and brushless-DC FET drivers.
When designing with the RX130, place the decoupling network as close as possible to the power pins, route touch-sensing traces with guard rings, and confirm IEC60730 firmware libraries are linked when targeting white-goods safety standards. Always validate the touch-sensing threshold with the production PCB stack-up.

典型應用
R5F51308ADFN#30 適用於 7 應用s: Home Appliance User Interface with Touch Keys, Industrial Control Panel HMI, Battery-Powered Smart Sensor Node, Building Automation Keypad and Thermostat, Small BLDC / Fan Motor Controller, Smart Home Sensor Hub, White Goods IEC60730 Safety Controller.
Home Appliance User Interface with Touch Keys
The R5F51308ADFN#30 is purpose-built for capacitive-touch user interfaces on washing machines, ovens, microwaves, and induction cooktops. Up to 36 capacitive-touch channels with improved noise immunity allow reliable operation behind glass up to 10 mm thick, while water-resistance ensures keys still respond when the surface is wet. The 32 MHz RXv1 core runs the IEC60730 class-B self-test libraries concurrently with UI state machines, and the wide 1.8 V to 5.5 V supply lets designers power the MCU directly from a 5 V rail without an LDO. Compared with discrete touch-IC plus MCU designs, the R5F51308ADFN#30 reduces BOM count and PCB area.

Industrial Control Panel HMI
The R5F51308ADFN#30 fits 5 V industrial HMI panels where a 32-bit core, capacitive-touch keys, and a 12-bit ADC must coexist on a single chip. With 50 DMIPS performance, the MCU handles graphical menu rendering, analog sensor reading, and serial protocols (RS-485, UART, I2C) simultaneously. Up to 6 communication channels enable bridging to motor controllers, displays, and remote I/O. The 80-LFQFP exposes ample GPIO for parallel TFT or segment LCDs and for driving status LEDs directly.

Battery-Powered Smart Sensor Node
The R5F51308ADFN#30's wide 1.8 V to 5.5 V supply range and on-chip RTC make it ideal for battery-operated sensor nodes running on 2x AA cells. Low-power sleep modes combined with RTC wake-up extend battery life to multi-year levels, while the 32 MHz core wakes fast enough to process sensor data and transmit via UART or I2C before returning to sleep. The integrated 12-bit ADC handles analog sensors such as temperature, humidity, and gas detectors directly.

Small BLDC / Fan Motor Controller
The R5F51308ADFN#30 controls small brushless DC fans and pumps where a 32-bit core, ADC for back-EMF sensing, and PWM timers are required. The 50 DMIPS core runs sensorless commutation algorithms, while the 12-bit ADC samples phase voltages for zero-crossing detection. Up to 6 comm channels enable UART diagnostics plus PWM outputs for the three-phase FET bridge.
推薦
Smart Home Sensor Hub
The R5F51308ADFN#30 functions as a low-cost hub aggregating multiple I2C and UART sensors behind a single BLE or Wi-Fi companion radio. The MCU's 48 KB SRAM buffers sensor frames while the RXv1 core formats JSON payloads and manages the capacitive-touch front panel for local override. The wide voltage range allows the hub to be powered from a USB 5 V rail or 3.3 V LDO.

White Goods IEC60730 Safety Controller
The R5F51308ADFN#30 targets white-goods safety controllers where IEC60730 class-B compliance is mandatory. On-chip self-test hardware plus Renesas-certified firmware libraries run alongside the main application, monitoring the CPU, RAM, flash, clock, and ADC for fault injection. The 80-LFQFP package supports the wide operating temperature range of -40C to +85C required for appliance compartments near heating elements.

主要差異化特點
- Industry-leading 36-channel capacitive-touch hardware (對比STM32G071 (Cortex-M0+ MCU))
- On-chip IEC60730 class-B hardware self-test (對比Generic Cortex-M0+ MCUs without class-B hardware)
- Wide 1.8 V to 5.5 V single-supply operation (對比RX230 (RXv2 core))
設計說明
Place a 4.7 uF bulk capacitor plus a 0.1 uF ceramic decoupling cap on each VDD/VSS pair of the R5F51308ADFN#30, located within 5 mm of the MCU pins. The wide 1.8 V to 5.5 V supply range allows direct 5 V rail operation, but still requires local decoupling to suppress digital switching noise on the analog supply pins used by the ADC and capacitive-touch peripherals.
Route capacitive-touch traces with a guard ring tied to a quiet GND, keep touch electrodes on a separate PCB layer with no overlapping noisy digital traces, and use hatched copper pour to reduce parasitic capacitance. The R5F51308ADFN#30's improved touch algorithm is more tolerant than legacy RX designs, but proper layout remains essential for water resistance.
Do not skip the IEC60730 class-B firmware library integration when targeting white-goods safety certification - the on-chip self-test hardware requires the linked Renesas library to actually invoke the diagnostic routines. Also, confirm the touch-sensing threshold using the production PCB stack-up rather than an evaluation board, because substrate differences will shift touch sensitivity.
