The SH7710 32bit RISC microprocessor features an IPsec accelerator for fast encryption and communication processing. The device also offers two on-chip Ethernet controllers that enable connection to two Ethernet LANs. Both peripherals make it suitable for security-enabled devices designed for use in networks, such as VPN dedicated boxes, home gateway servers, surveillance cameras and IP phones.

    The SH7710 is based on a SuperH RISC SH3-DSP CPU core that operates at speeds of up to 200MHz and achieves a high processing capability of 260MIPS. The on-chip DSP supports various kinds of middleware, such as a voice codec and echo canceller, and enables fast execution of multimedia related processing such as VoIP.
