What this RX651 MCU carries on the die
The Renesas R5F56517EGFP#30 is a 32-bit microcontroller from the RX651 series, built around the RXv2 core running at 120 MHz. It packs 768 KB of Flash and 256 KB of RAM — enough to run a real-time control loop with a TCP/IP stack and a modest data buffer, but not a full graphical display. The peripheral set includes Ethernet, CAN, USB, multiple SPI/I²C/UART channels, and a 22-channel 12-bit ADC plus a single 12-bit DAC. All of this lives in a 100-pin LQFP package with 78 usable I/O lines.
Industrial temperature and supply range
Rated for -40°C to 105°C ambient and 2.7 V to 3.6 V supply.
Connectivity mix for industrial nodes
Ethernet MAC, CAN 2.0, and USB full-speed on the same die make this a single-chip candidate for an industrial Ethernet gateway, a CAN-to-Ethernet bridge, or a USB-logging data concentrator. The EBI/EMI bus also means you can hang an external SRAM or FPGA without bit-banging GPIO.
Active lifecycle — no LTB pressure
The R5F56517EGFP#30 carries an Active lifecycle status. The RX651 series is an active portfolio line from Renesas, so PCN risk is low and supply continuity is predictable.
