News Releases 

Tokyo, November 15, 2006 −− Renesas Technology Corp. today announced the 32-bit SuperH*¹ Family SH7652 microprocessor with an on-chip Ethernet controller, incorporating the industry’s first encryption/decryption functions supporting both the copyright protection function for IP broadcasting*² will start in Japan, and the DTCP-IP*³ copyright protection standard for in-home distribution, for use in digital audiovisual and office automation devices with built-in network functions.  Sample shipments will begin in January 2007 in Japan.

As enhancements to current 133 MHz SH7650 with DTCP-IP functions, the SH7652 features the addition of a copyright protection function for IP broadcasting in Japan, a more comprehensive range of peripheral functions, and a 50% increase in operating speed to 200 MHz.

The SH7652 offers the following features.

The SH7652 can easily be connected to another  microprocessors or CPU via an on-chip host interface function.  This function enables a main microprocessors  performing system control to handle the SH7652 as an SRAM-equivalent device in performing data transmission and reception.  This allows control as an Ethernet controller, enabling network related function development to be carried out independently, and simplifying user product development.


< Development Background >

Progress has been made in connecting digital home appliances compliant with  DLNA*⁸ standard to a home network.  Moreover, the inauguration of a digital broadcasting service dubbed IP broadcasting is planned in Japan, and the start of digital content distribution inside and outside the home will begin.

Meanwhile, authentication and content encryption processing between devices are essential when transferring copyright protected digital content via a network in order to protect content on the network from unauthorized access.

Renesas Technology previously released SH7650 featuring DTCP-IP content protection standard for in-home distribution compatible functions and an Ethernet controller, and has now developed the 32-bit SuperH Family SH7652 incorporating IP broadcasting copyright protection support functions, DTCP-IP in-home content protection standard compliant functions, and an Ethernet controller for the market growth.


< Product Details >

The SH7652 incorporates 32-bit SH-2A CPU core with a built-in double–precision FPU, and an Ethernet controller.  With processing power of 480 MIPS (million instructions per second) at a maximum operating frequency of 200 MHz, and copyright protection support functions, it is ideal for use in digital audiovisual and office automation devices with built-in network functions.

The copyright protection support functions provided in the SH7652 comprise a hardware encryption/decryption circuit block, and firmware for encryption/decryption circuit block and content data transfer control.

The SH7652 includes two video stream port channels that enable high-speed transfer of MPEG-2*⁹ TS (Transport Stream) and MPEG-2 PS (Program Stream) format data.  These ports can be connected to an MPEG-2 encoder/decoder chip, enabling encrypted data received via a network to be decrypted, and transferred to an MPEG-2 chip at high speed as MPEG-2 TS format video data.  Also, performing high-speed encryption of content data by means of the on-chip encryption circuit before transmission via a network makes it possible to achieve simultaneous secure network transfer of HD digital content on two channels.

The SH7652 also includes a comprehensive range of peripheral functions.

A single-channel Ethernet controller is provided that facilitates connection to a 10/100 Mbps Ethernet LAN.  This Ethernet controller incorporates an IEEE802.3 compliant MAC layer, and an accelerator that performs TCP/IP checksum computations automatically without software intervention, reducing the load on the CPU.

USB and SD Memory Card host interfaces are also included, allowing connection to external devices such as an external storage and a wireless LAN module.  An on-chip serial sound interface and I²C bus used by digital audiovisual and office automation devices simplify system design, while the provision of a host interface function allows easy connection to a main microprocessor for user product control or the like.  This interface performs high-speed transfer of data and commands between a main microprocessor or CPU and the SH7652 via a 16-bit bus.  Use of this interface also allows network connection functions to be developed in parallel with basic user product functions, enabling development time to be shortened.

These functions enable network processing and multiple copyright protection supporting to be implemented by a single chip without imposing a load on the main microprocessor or CPU, and make possible simultaneous two channels distribution of HD digital content.

The package used is a 240-pin CSP (13 mm × 13 mm).

On-chip debugging functions are provided, and the small, PC card sized E10A-USB can be used as an emulator.

The SH7652 will be exhibited at "Embedded Technology 2006" being held at Pacifico Yokohama from November 15 to 17.

Renesas Technology will continue to extend its lineup of products with an on-chip Ethernet controller, including the provision of models offering faster CPU performance, wireless LAN support, and enhanced peripheral functions.
