RX65N at 120 MHz — what the core speed buys you
The Renesas R5F565N7BGFB#30 is a 32-bit RX65N series microcontroller built around the RXv2 CPU core running at 120 MHz. That clock rate, combined with a single-cycle multiply and hardware divide, gives it the throughput for real-time control loops in motor drives, PLCs, and industrial gateways. The 768 KB of program Flash and 256 KB of SRAM leave headroom for a full TCP/IP stack plus a RTOS scheduler without squeezing the firmware into overlays.
Peripheral set for a single-chip gateway
This part carries Ethernet MAC, dual CAN 2.0B channels, USB 2.0 full-speed, and a Quad-SPI interface for external Flash or PSRAM expansion. The 111 GPIOs in the 144-LQFP package give enough pins to drive a local display, keypad, and sensor inputs alongside the network interfaces.
Package and board integration
The 144-LQFP (20x20 mm body, 0.5 mm pitch) is a standard QFP footprint that routes easily on a four-layer board. No exposed pad means the thermal path is through the leads — keep the copper pour under the package and stitch vias to the ground plane for junction temperature management above 85°C ambient. MSL 3 handling applies; bake before reflow if the moisture-barrier bag has been open past the floor-life window.
