The SH7670 incorporates SH2A-FPU core. The SH7670 achieves processing performance of 480 MIPS when running at the maximum operating frequency of 200 MHz. The on-chip Ethernet controller incorporates an IEEE802.3-compliant MAC layer. In addition, the SH7670 is the first product incorporating an Ethernet controller, USB 2.0 host and function module on a single chip, eliminating the need for a dedicated external LAN controller and USB 2.0 LSIs.
