Product details

The Renesas R5F566TFCGFB#30 is a 32-bit RXv3 microcontroller running at 160 MHz, built for deterministic real-time control in industrial and automotive-adjacent applications. 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.

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.

Frequently asked questions

Does R5F566TFCGFB#30 have a CAN bus interface?

Yes, the connectivity block includes CANbus, along with USB, I²C, SPI, SCI, LINbus, and an EBI/EMI bus for external memory or FPGA.

What is the maximum clock speed of R5F566TFCGFB#30?

The RXv3 core runs at 160 MHz, which is the maximum rated speed for this device.

Does R5F566TFCGFB#30 have a built-in ADC?

Yes, the part integrates a 30-channel 12-bit ADC and a 2-channel 12-bit DAC for analog signal acquisition and output.

What is the equivalent of R5F566TFCGFB#30?

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. The R5F566TFCGFB#30 offers more I/O (110 vs 72) and more ADC channels (30 vs 22) in the larger 144-pin LQFP. Neither is a drop-in replacement — the pin count and footprint differ — but the code base and peripheral register map are compatible across the RX66T family.
