That clock rate, combined with the DMA engine and the on-chip 256 KB RAM, gives it the headroom to run a real-time OS, a TCP/IP stack, and a fieldbus protocol without starving the control loop. ## On-chip memory budget — 512 KB flash, 256 KB RAM Program memory is 512 KB of flash, with 256 KB of SRAM. That RAM allocation is enough to buffer two full Ethernet frames (1536 bytes each) plus a CAN message queue and still leave room for the application heap. The flash size supports a full Renesas FSP or Azure RTOS footprint with room for a modest application image. ## Wired connectivity without an external bridge The peripheral set includes Ethernet MAC, dual CAN 2.0B channels, USB 2.0 Full Speed, and multiple SCI/SPI/I²C serial interfaces. That means a single MCU handles the three most common industrial fieldbuses — EtherNet/IP, CANopen, and Modbus RTU — without an external communication coprocessor. The 111 general-purpose I/O pins, combined with the EBI/EMI bus, allow direct connection to external SRAM, NOR flash, or an FPGA over a parallel memory interface without glue logic. ## Analog front-end — 29-channel ADC, dual DAC The 12-bit ADC scans 29 channels — enough to monitor three-phase motor currents, DC bus voltage, and four temperature sensors in a single conversion sequence. The dual 12-bit DAC can generate analog setpoints or bias voltages without an external converter. The -40 to +105 °C operating range covers the industrial ambient band with margin for self-heating. Supply voltage is 2.7 to 3.6 V, compatible with a single 3.3 V rail. ## Active lifecycle — no end-of-life signal ROHS3 compliant.","metaTitle":"R5F565N4BGFB#30 Renesas RX65N MCU, 120 MHz, 512 KB Flash","metaDescription":"R5F565N4BGFB#30 Renesas RX65N 32-bit MCU: RXv2 core at 120 MHz, 512 KB flash, 256 KB RAM, Ethernet + CAN + USB, -40 to +105 °C, 144-LQFP.","metaKeywords":null},"attributes":{"series":"RX65N","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"120MHz","Series":"RX65N","Package":"Tray","RAM Size":"256K x 8","Core Size":"32-Bit","Peripherals":"DMA, LVD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, LINbus, MMC/SD, QSPI, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"111","Core Processor":"RXv2","Package / Case":"144-LQFP","Data Converters":"A/D 29x12b; D/A 2x12b","Oscillator Type":"External","lifecycle_stage":"eol_hot","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"144-LFQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"2.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.91","stockQuantity":23,"priceTiers":[{"qty":1,"price":"$7.91000","currency":"USD"},{"qty":10,"price":"$7.28300","currency":"USD"},{"qty":25,"price":"$7.13080","currency":"USD"},{"qty":60,"price":"$7.10633","currency":"USD"},{"qty":120,"price":"$6.37642","currency":"USD"},{"qty":240,"price":"$6.18371","currency":"USD"},{"qty":480,"price":"$5.88025","currency":"USD"},{"qty":960,"price":"$5.67523","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/938c04aae8789a5a2f6d31b417abe402.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will R5F565N4BGFB#30 drop into a board designed for R5F565N9BGFB#30?","answer":"The R5F565N9BGFB#30 is a pin-compatible peer in the same RX65N series — same package, same I/O count, same peripheral set.
