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
On-chip data converters include a 29-channel 12-bit ADC and a 2-channel 12-bit DAC, enough for three-phase current sensing plus an analog output for setpoint or trim. 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.
