For a control node that needs CAN connectivity and encrypted firmware updates, the R5F51406BGFL#10 eliminates the external CAN transceiver interface logic and a separate security coprocessor. The 11-channel 12-bit ADC covers analog sensor inputs, while 39 GPIOs in the 48-LQFP package leave room for a local display or keypad alongside the bus interface. For a BOM that needs a 32-bit MCU with CAN and industrial temperature range, this part is qualified for new designs without a near-term obsolescence risk. The RX140 series is Renesas's current mid-range offering, so roadmap continuity and toolchain support are expected through the product's service life. This part is available to source through independent distribution. A quote request locks the current market position.","metaTitle":"R5F51406BGFL#10 Renesas RX140 32-bit MCU, 48 MHz","metaDescription":"R5F51406BGFL#10 Renesas RX140 32-bit MCU with RXv2 core at 48 MHz, 256 KB Flash, 64 KB RAM, 8 KB EEPROM, CAN, capacitive touch, AES, -40°C to 105°C.","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":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"8K x 8","Peripherals":"AES, Capacitive Touch, DMA, LVD, POR, PWM, Temp Sensor, TRNG, WDT","Connectivity":"CANbus, I²C, SCI, SPI","Mounting Type":"Surface Mount","Number of I/O":"39","Core Processor":"RXv2","Package / Case":"48-LQFP","Data Converters":"A/D 11x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"48-LFQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.25","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.25000","currency":"USD"},{"qty":10,"price":"$3.85400","currency":"USD"},{"qty":25,"price":"$3.77040","currency":"USD"},{"qty":40,"price":"$3.75000","currency":"USD"},{"qty":80,"price":"$3.36225","currency":"USD"},{"qty":230,"price":"$3.35000","currency":"USD"},{"qty":440,"price":"$3.22759","currency":"USD"},{"qty":2000,"price":"$3.03582","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/553b3af22590916e0689f691c6103527.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does R5F51406BGFL#10 have a CAN bus interface?","answer":"Yes, the R5F51406BGFL#10 includes a CANbus controller as part of its connectivity peripheral set, alongside I²C, SCI (UART), and SPI interfaces."},{"question":"What is the closest functional peer to R5F51406BGFL#10 within the RX140 family?","answer":"The R5F51405BGFL#30 is the closest functional peer.
