The ADC resolution is adequate for most industrial sensor interfaces; the DAC can generate analog setpoints or bias voltages. ## Connectivity and peripheral set The MCU includes CANbus, I²C, SCI, and SPI interfaces, making it suitable for industrial network nodes and multi-sensor aggregators. The capacitive touch peripheral supports touch-button or slider interfaces without an external touch controller. The 53 general-purpose I/O pins provide ample headroom for parallel displays, keypads, and actuator control. ## Package and footprint — 64-LQFP (14x14 mm) The device is supplied in a 64-pin LQFP package with a 14x14 mm body, a standard footprint for medium-density MCU designs. The surface-mount package is compatible with reflow soldering and typical PCB assembly processes. ## Lifecycle and supply posture The part is RoHS3 compliant. For BOM planning, this MCU is a safe choice for production programs that will run for several years.","metaTitle":"R5F51405AGFK#10 Renesas RX140 32-bit MCU, 48 MHz","metaDescription":"R5F51405AGFK#10 Renesas RX140 32-bit MCU: RXv2 core at 48 MHz, 128 KB Flash, 32 KB RAM, 8 KB EEPROM, 53 I/O, 15-ch 12-bit ADC, CANbus, -40°C to 105°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":"RX140","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Speed":"48MHz","Series":"RX140","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"8K x 8","Peripherals":"Capacitive Touch, DMA, LVD, POR, PWM, Temp Sensor, WDT","Connectivity":"CANbus, I²C, SCI, SPI","Mounting Type":"Surface Mount","Number of I/O":"53","Core Processor":"RXv2","Package / Case":"64-LQFP","Data Converters":"A/D 15x12b; D/A 2x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"64-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.62000","currency":"USD"},{"qty":10,"price":"$3.28200","currency":"USD"},{"qty":25,"price":"$3.21040","currency":"USD"},{"qty":40,"price":"$3.19300","currency":"USD"},{"qty":80,"price":"$2.86288","currency":"USD"},{"qty":230,"price":"$2.85248","currency":"USD"},{"qty":720,"price":"$2.74825","currency":"USD"},{"qty":1440,"price":"$2.61275","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/553b3af22590916e0689f691c6103527.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for the R5F51405AGFK#10?","answer":"The R5F51405AGFL#10 is a pin-compatible variant in the same RX140 series with the same core speed, memory sizes, and peripheral set, but with 39 I/O instead of 53.
