The 512 KB on-chip Flash and 128 KB RAM hold a substantial firmware image and data buffers without external memory, while the 32 KB dedicated EEPROM block stores calibration constants and configuration parameters that survive power cycles. With 110 I/O lines in a 144-pin LQFP, this part suits parallel display interfaces, large sensor arrays, or multi-axis motion control where pin count is the binding constraint. ## Connectivity and analog density The peripheral set includes CANbus, USB, SCI/UART, SPI, I²C, and an EBI/EMI bus. The 30-channel 12-bit ADC and two 12-bit DACs handle analog I/O. Supply range is 2.7 V to 5.5 V. ## Temperature grade and deployment envelope Rated for -40°C to 105°C ambient, this MCU is specified for factory-floor enclosures, outdoor telecom cabinets, and under-hood electronics where the junction temperature climbs. The internal oscillator eliminates the external crystal for cost-sensitive builds, though the EBI/EMI bus and USB PHY still benefit from a precision clock source when timing margin is tight. ## Lifecycle and sourcing posture That means it remains a valid selection for new production builds and ongoing BOM lines. No stock or price figures are published here because the channel position changes daily — submit an RFQ for the real-time picture.","metaTitle":"Renesas R5F566TFCGFB#30 RXv3 32-bit MCU, 160 MHz","metaDescription":"R5F566TFCGFB#30 from Renesas RX series: 160 MHz RXv3 core, 512 KB Flash, 128 KB RAM, 32 KB EEPROM, 110 I/O, CAN, USB, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"RX","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Speed":"160MHz","Series":"RX","Package":"Tray","RAM Size":"128K x 8","Core Size":"32-Bit","EEPROM Size":"32K x 8","Peripherals":"DMA, LVD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, LINbus, MMC/SD, SCI, SPI, SSI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"110","Core Processor":"RXv3","Package / Case":"144-LQFP","Data Converters":"A/D 30x12b; D/A 2x12b","Oscillator Type":"Internal","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 ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.60000","currency":"USD"},{"qty":10,"price":"$7.91000","currency":"USD"},{"qty":25,"price":"$7.74560","currency":"USD"},{"qty":60,"price":"$7.71900","currency":"USD"},{"qty":120,"price":"$6.92617","currency":"USD"},{"qty":240,"price":"$6.71679","currency":"USD"},{"qty":480,"price":"$6.38719","currency":"USD"},{"qty":960,"price":"$6.16448","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f3865365e9f0ed618393b05ad848644f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does R5F566TFCGFB#30 have a CAN bus interface?","answer":"Yes, the connectivity block includes CANbus, along with USB, I²C, SPI, SCI, LINbus, and an EBI/EMI bus for external memory or FPGA."},{"question":"What is the maximum clock speed of R5F566TFCGFB#30?","answer":"The RXv3 core runs at 160 MHz, which is the maximum rated speed for this device."},{"question":"Does R5F566TFCGFB#30 have a built-in ADC?","answer":"Yes, the part integrates a 30-channel 12-bit ADC and a 2-channel 12-bit DAC for analog signal acquisition and output."},{"question":"What is the equivalent of R5F566TFCGFB#30?","answer":"The closest functional sibling is the R5F566TAAGFP#30, which shares the same RXv3 core at 160 MHz and the same peripheral set (CAN, USB, serial, DMA, PWM) but in a 100-pin package with 72 I/O and 22 ADC channels.
