160 MHz RXv3 core with 256 KB Flash — what the memory budget means
The Renesas R5F566TAFGFP#30 is a 32-bit RXv3 microcontroller from the RX series, clocked at 160 MHz. The 160 MHz core with the RXv3 pipeline gives enough headroom for a single motor-control loop running field-oriented control at 20 kHz while the CANbus and UART stacks service the host controller.
Peripheral set for industrial control panels
The 22-channel 12-bit ADC and dual 12-bit DAC handle analog feedback and setpoint generation on the same chip, which saves a separate analog front-end on a motor-drive board.
The 2.7 V to 5.5 V supply range means a single 5 V industrial rail powers the MCU directly — no intermediate 3.3 V regulator needed unless the peripheral set demands it.
Package and physical fit
The 100-LFQFP supplier package code matches the same footprint. Standard reflow profile for LQFP applies;.
Officially active, ROHS3 compliant — no last-time-buy risk for new designs. For dual-sourcing resilience, the R5F566TAAGFP#30 is a functional peer with the same RXv3 core, 160 MHz speed, and identical peripheral set, differing only in I/O count (72 vs 73) — worth qualifying as a second source if your BOM allows the minor pin difference.
