The SH7780 microprocessor combines the high-end SuperH SH-4A CPU core with a PCIbus controller.
Platform speeds latest SuperH development
The SDK7780 is a system development kit for the recently announced SH-4A-based SuperH microprocessor SH7780.
Furthermore it consumes only 2.5W, is available in a -40 to +85C version, integrates PCI, has a long life time, and is low in cost compared with a Pentium microprocessor of similar FPU performance.
The superscalar SH7780 uses a SH-4A CPU plus FPU core, with a maximum operating frequency of 400MHz.
Its 64Kbyte four-way set-associative cache memory is divided into two 32Kbyte areas, one for instructions and one for data.
The 128bit internal real-time router bus (SuperHyway) optimises on-chip data traffic.
The SH7780 has three independent external buses, a 32bit DDR320-SDRAM controller, standard NOR Flash, NAND Flash controller, PCMCIA and ATAPI controller.
It has a MultiMedia card interface and a 32bit PCI 2.2 controller at 33/66MHz, two-channel serial interface with on-chip FIFO, and an audio codec interface.
The powerful FPU calculates 3D graphics using internal DSP-like instructions (MAC, DIV, SQRT), supports single and double precision (64bit) and has a 10-stage pipeline for optimised performance.
The SH7780 is supported by all relevant high-end operating systems such as WinCE, Linux and QNX via the Renesas Platinum Alliance Partners emtrion and MPC-Data.
The SH7780 device is available immediately (R8A77800BDBGV) as is the SDK7780-R4 development kit.
