200 MHz RXv3 core — what it means for the control loop
The Renesas R5F572TFCGFP#30 is a 32-bit RXv3 microcontroller running at 200 MHz, with 512 KB of Flash program memory, 128 KB of RAM, and a separate 32 KB EEPROM block. It is built for industrial real-time control — motor-drive current loops, multi-axis servo coordination, and protocol bridging between Ethernet and CAN fieldbuses. The 200 MHz clock rate gives it a 40 MHz advantage over the 160 MHz RX66T siblings, which matters when closing a 16 kHz current loop with a 12-bit ADC read, a PI calculation, and a PWM update inside one switching cycle.
Peripheral set for a multi-protocol gateway node
Connectivity includes Ethernet, CAN, USB OTG, QSPI, and an external bus interface (EBI/EMI). That combination lets a single MCU serve as a protocol translator — for example, reading a CANopen motor drive and publishing its status via Modbus TCP over Ethernet, while logging data to an SD card over the MMC/SD interface. The 24-channel 12-bit ADC and dual 12-bit DAC cover analog sensing and setpoint generation without external converters.
Industrial temperature grade and supply range
Rated for -40°C to 105°C ambient, this MCU handles the thermal extremes of a sealed motor-drive enclosure or an outdoor telecom cabinet. The supply range from 2.7 V to 5.5 V allows direct connection to a 5 V industrial bus or a 3.3 V regulated rail without a level shifter on the I/O.
100-LQFP — rework-friendly, no BGA complexity
The 100-pin LQFP (14x14 mm body) is a package that survives a rework cycle. With a fine-tip iron and hot air you can lift the part without lifting the pad — just watch the adjacent passives. MSL 3 out of the bag; bake before reflow if the moisture-barrier bag has been open past the floor-life window.
Active lifecycle — no last-time-buy pressure
Renesas lists the R5F572TFCGFP#30 as an active, current-production device. This means you can qualify it into a new design without scheduling a last-time buy or planning a migration. ROHS3 compliant.
