The SH7780 uses an SH-4A CPU core with a maximum operating frequency of 400MHz. The four-way set-associative cache memory is divided into two 32-Kbyte areas, one for instructions and one for data. The SH7780 incorporates an on-chip 32-bit PCI bus controller which allows connections with LSI devices incorporating PCI interfaces and operating at either 66 MHz or 33 MHz. It employs three kinds of bus: a 32-bit bus for connections to double data rate synchronous DRAM (DDR-SDRAM), a 32-bit bus for PCI bus connections, and a 32-bit local bus for connecting to flash memory, SRAM, etc. Also the SH7780 incorporates a wide range of peripheral functions such as DMAC, SCIF, RTC, FLCTL, TMU, SSI, HAC, MMCIF, etc.
