Renesas has introduced a total of eight products in four groups in the SH7670 group of the SuperH family. These microprocessors each incorporate an Ethernet controller and USB 2.0 host and are intended for applications such as digital audio visual, office automation, and factory automation systems requiring network connection functionality.
The SH7670 has a maximum operating frequency of 200 MHz and yields 480 DMIPS at that speed. It also has a single/double-precision floating point unit (FPU), which is in demand by many engineers who develop their algorithms on PCs using high-level-abstraction tools such as Matlab. Without an FPU these algorithms will slow down dramatically when the application is moved from the PC to a microcontroller.
The SH7670 implements an IEEE802.3 compliant media access controller (MAC) that makes it easy to develop systems supporting 10/100 Mbps Ethernet LAN connections. It also incorporates USB 2.0 high-speed (480 Mbps) host and function module capabilities, simplifying development of USB functionality.
The host interface (HIF) enables connections between the SH7670 and another processor. This function enables the SH7670 to be recognised and controlled as an SRAM-equivalent device by a main microprocessor performing system control. The SH7670 as a 16-bit bus device allows high-speed command transmission and rapid transfer of large amounts of data. This facilitates its integration into existing systems. Also, use of the HIF boot function eliminates the need for external non-volatile memory such as Flash, reducing the number of parts required.
In addition to the above, an audio codec can be connected via the serial sound interface, making it easy to implement a VoIP system. Other on-chip peripheral functions include an SD host interface and I²C bus interface.
A JTAG on-chip debugging function is included that enables realtime debugging at the maximum operating frequency. A compact PC card size emulator, the E10A-USB, is available.
