The superscalar SH7780 uses a SH-4A CPU + FPU core, with a maximum operating frequency of 400MHz. Its 64kB, four-way set-associative cache memory is divided into two 32-Kbyte areas, one for instructions and one for data. The 128-bit internal real-time router bus (SuperHyway) optimises on-chip data traffic.
The SH7780 has 3 independent external busses, 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, 2-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.
