Renesas Technology Introduces Powerful RISC Microprocessor with Integrated Network Connectivity for Multitasking6 June 2005
Renesas Technology America, Inc. today announced the SH7619 SuperH®(1) 32-bit RISC microprocessor, the company's first device to incorporate an IEEE-802.3 compliant Ethernet media access controller (MAC) and a physical layer (PHY) transceiver. This device can be used to enable network connectivity for a variety of products, including digital audio-visual equipment, office automation products, and factory automation systems. It is also ideal for consumer broadband voice-over-IP (VoIP) end points.
Based on the 32-bit SH-2 RISC CPU core, the SH7619 runs at a maximum frequency of 125 MHz and delivers 163 million instructions per second (MIPS) of processing performance. The on-chip 16-KB 4-way set-associative cache helps improve the cache hit-rate in program execution. An additional 16-KB user RAM is available to store instructions and data for faster access. The SH7619 can execute TCP/IP, middleware stacks, and other networking protocols at high speeds, and it enables the implementation of high-performance systems.
The on-chip Ethernet MAC and PHY transceiver help reduce the component count and simplify the development of 10/100 Mbit/s Ethernet systems. Two dedicated direct memory access controller (DMAC) channels with transmit and receive First In First Outs (FIFOs) of 512 bytes each facilitate high-speed data transfers over an Ethernet network.
The SH7619's host interface function (HIF) has an SRAM-equivalent interface that allows easy connection to the main microprocessor that performs system control functions in multi-processor systems. The HIF comprises a 16-bit interface bus and two SRAM banks, each with a 1-KB linear address space. This function allows the main microprocessor to directly read from and write to the SRAM banks, and enables high-speed data transfers between the Ethernet port and the main microprocessor. Also, the HIF has a boot mode that allows a program stored in the flash memory connected to the main microprocessor to be downloaded via the host interface to the SDRAM connected to the SH7619 processor. This mode effectively eliminates the need for separate program storage for the SH7619.
With the HIF, the development of a system's basic functions can be carried out in parallel with development of its network-connection related functions. The parallel development activities reduce the overall system design and debug time and simplify the process of adding an Ethernet connection function to an existing system.
The SH7619 microprocessor includes a comprehensive set of on-chip peripherals. A general-purpose DMA controller provides high-speed data transfers to and from external memory. An on-chip serial I/O interface allows connection to a voice CODEC, facilitating the implementation of VoIP systems. To accelerate VoIP designs, Renesas is developing a low-cost consumer broadband VoIP analog telephone adapter (ATA) reference design based on the SH7619. The design will include a complete package of VoIP middleware.
The small (13 mm x 13 mm) 176-pin BGA package of the SH7619 helps minimize circuit board size. The device provides on-chip debugging functions that enable real-time debugging at the 125-MHz maximum operating frequency. For system debugging, the small PC-card-size E10A-USB can be used as an emulator.
