It includes a capacitive touch sensing unit, DMA controller, LVD, POR, PWM timers, and a watchdog timer — all in a 64-pin LQFP package. The wide supply range from 1.8 V to 5.5 V and industrial temperature grade of -40°C to 105°C make it a fit for motor drives, outdoor telecom, factory automation panels, and HMI applications where touch control is needed without a separate touch controller IC. ## Key features that shape the BOM The capacitive touch peripheral is the headline differentiator here — it integrates self-capacitance and mutual-capacitance sensing directly into the MCU, saving a dedicated touch controller and its associated I²C or SPI bus. That matters for panel retrofits or new HMI designs where board space and BOM cost are tight. The 52 general-purpose I/O lines give enough headroom for a small keypad, a few LEDs, and a serial interface to a display or host controller. Data converters include a 14-channel 12-bit ADC and a 2-channel 8-bit DAC, sufficient for reading analog sensors (potentiometers, current shunts) and generating simple analog outputs or reference voltages. The 64 KB Flash and 10K x 8 RAM are modest — this is a control-oriented MCU, not a data-logging engine. If your firmware footprint exceeds 64 KB, step up to the RX130 family's higher-density variants. ## Temperature grade and deployment environment Rated for -40°C to 105°C ambient, this part is suited for industrial enclosures, engine-bay-adjacent electronics, outdoor base stations, and any environment where the PCB sees seasonal temperature swings or self-heating from nearby power stages. The 64-LQFP package (10x10 mm body) is a standard footprint for automated assembly and rework. ## Lifecycle and sourcing posture R5F51303AGFM#30 carries an Active lifecycle status from Renesas, with ROHS3 compliance confirmed. It is a current-production part, not subject to last-time-buy or end-of-life notices as of the latest records. For new designs, this MCU is a safe selection — no near-term obsolescence risk.","metaTitle":"R5F51303AGFM#30 RX130 32-bit MCU, 32MHz, 64KB Flash, 64-LQFP","metaDescription":"R5F51303AGFM#30 from Renesas RX130 series: 32-bit MCU at 32MHz with 64KB Flash, 10K x 8 RAM, 8K x 8 EEPROM, capacitive touch, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"RX130","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Speed":"32MHz","Series":"RX130","Package":"Tray","RAM Size":"10K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"8K x 8","Peripherals":"Capacitive Touch, DMA, LVD, POR, PWM, WDT","Connectivity":"I²C, LINbus, SCI, SPI","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"RX","Package / Case":"64-LQFP","Data Converters":"A/D 14x12b; D/A 2x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"64-LFQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.08000","currency":"USD"},{"qty":10,"price":"$2.76600","currency":"USD"},{"qty":25,"price":"$2.72280","currency":"USD"},{"qty":40,"price":"$2.71575","currency":"USD"},{"qty":160,"price":"$2.42669","currency":"USD"},{"qty":320,"price":"$2.34691","currency":"USD"},{"qty":480,"price":"$2.33838","currency":"USD"},{"qty":960,"price":"$2.17745","currency":"USD"},{"qty":4960,"price":"$1.97095","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1014991a8edffdfb38ecb63690fdfb21.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is there a pin-compatible second source or replacement for R5F51303AGFM#30?","answer":"Within the same RX130 family, higher-density Flash/RAM variants share the same 64-LQFP footprint.
