　　The RX63N/RX631 Group incorporates communication functions suitable for networking equipment, such as Ethernet controller, USB 2.0 full-speed (function, host, or OTG selectable), and CAN. In addition, with a RTC (Real-Time Clock) that can operate on a dedicated power supply as a low power feature, standby power consumption can be reduced by approximately 90% compared to existing products. The selection of on-chip memory has been expanded from ROMless to 2 MB, and even smaller-sized packages are available. This makes possible mounting in anything from large-scale systems to small-scale/small-space devices.
