It carries 2 MB of program Flash and 1 MB of SRAM, plus 32 KB of data Flash emulating EEPROM — enough headroom for a real-time control stack with Ethernet and CAN stacks loaded without external memory. The 78 GPIOs are mapped across a 100-LQFP package; the 22-channel 12-bit ADC and single 12-bit DAC handle sensor acquisition and analog output on the same die. ## Connectivity and peripherals for industrial gateway and motor control The peripheral list is built for a node that talks to the outside world: Ethernet MAC, CAN (2.0B), USB OTG, QSPI, multiple SCI/UART and I²C/SPI channels, plus an EBI/EMI bus for external memory or FPGA glue. DMA and PWM channels handle the real-time data movement and motor-timer waveforms without CPU intervention. The internal oscillator saves an external crystal if the application tolerates its accuracy, but the clock tree accepts an external resonator when tighter timing is needed. ## Industrial temperature range and supply voltage Rated for -40°C to 85°C ambient. Supply range is 2.7 V to 3.6 V, single rail. ## Lifecycle and sourcing posture The RX66N series is a current-generation Renesas platform; new designs can commit to this order code without near-term obsolescence risk. ROHS3 compliant.","metaTitle":"R5F566NDDDFP#30 RX66N 32-bit MCU, 120 MHz, 2 MB Flash","metaDescription":"R5F566NDDDFP#30 from Renesas RX66N series: 32-bit RXv3 core at 120 MHz, 2 MB Flash, 1 MB RAM, Ethernet, CAN, USB OTG, 22x12-bit ADC.","metaKeywords":null},"attributes":{"series":"RX66N","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Speed":"120MHz","Series":"RX66N","Package":"Tray","RAM Size":"1M x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"32K x 8","Peripherals":"DMA, LCD, LVD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, MMC/SD, QSPI, SCI, SPI, SSI, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"78","Core Processor":"RXv3","Package / Case":"100-LQFP","Data Converters":"A/D 22x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LFQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.3","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$18.30000","currency":"USD"},{"qty":10,"price":"$16.81400","currency":"USD"},{"qty":25,"price":"$16.11720","currency":"USD"},{"qty":90,"price":"$14.20056","currency":"USD"},{"qty":270,"price":"$13.50359","currency":"USD"},{"qty":450,"price":"$13.22640","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/26da7982fe9ad3de4d80cc4ad6df1dba.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does R5F566NDDDFP#30 have a CAN interface?","answer":"Yes, the connectivity block includes CANbus (CAN 2.0B) alongside Ethernet, USB OTG, I²C, SPI, QSPI, and SCI serial channels."},{"question":"What is the maximum clock speed of R5F566NDDDFP#30?","answer":"The RXv3 core runs at 120 MHz.
