120 MHz RXv2 core with Ethernet and CAN for industrial control
The R5F56514EGFB#30 is a 32-bit microcontroller from Renesas' RX651 series built around the RXv2 CPU core running at 120 MHz. The 111 I/O lines in a 144-LQFP package leave plenty of headroom for sensor arrays, parallel displays, or memory-mapped peripherals. The connectivity set—Ethernet, CANbus, USB, and QSPI—targets industrial gateways, motor drives, and PLCs that need both deterministic fieldbus communication and a plant-network uplink.
Peripheral mix and data conversion
DMA, LVD, POR, PWM, and WDT peripherals handle housekeeping so the CPU stays on control tasks. External oscillator only—the clock tree expects a crystal or canned oscillator on the EXTAL/XOUT pins.
Active lifecycle—no end-of-life clock ticking
Renesas lists this device as Active with an ROHS3 compliance status.
