The Renesas R5F566TFGGFP#30 is a 32-bit RXv3 microcontroller from the RX family, clocked at 160 MHz.
On the connectivity side, the MCU includes CAN, USB, EBI/EMI for external memory or FPGA glue, plus multiple I²C, SPI, SCI, and LINbus interfaces — covering fieldbus, HMI, and data-logging links on one die.
Housed in a 100-LQFP (also listed as 100-LFQFP) with a 14x14 mm body and 0.5 mm pitch. The 69 general-purpose I/O lines are accessible on the outer leads — no hidden balls, so visual inspection and rework are straightforward. Surface-mount only; the tray shipping medium is standard for QFP volumes.
