Renesas SuperH SH7727 32-bit RISC microprocessor
[Vendor: Renesas Technology Corp.]

The SH7727 is a true high-performance, single-chip multimedia solution, based on one of the world's leading 32-/64-bit RISC architectures, the SuperH RISC engine family. The 32-bit RISC microprocessor incorporates a SH3-DSP CPU core that provides a high speed processing performance of 208 MIPS and 320 MOPS at a 160MHz operating frequency. It comes complete with a comprehensive range of peripheral functions on a single chip, including a USB Host, USB Function and colour LCD controller, which enable the design of high performance, compact, low cost multimedia products. These include handheld PCs, portable information terminals, digital cameras and networked devices, such as multifunctional printers and phones supporting internet applications.

The SH7727 can simplify the development of products which incorporate a USB interface. The on-chip USB Host supports isochronous, interrupt, control, and bulk transfer, and with a maximum data transfer speed of 12 Mbit/s complies with OpenHCI (Open Host Controller Interface) specifications. The USB Function also supports interrupt, control, and bulk transfer, as well as incorporating a transceiver that eliminates the need for external parts, such as buffers. Both the USB Host and USB Function are compliant with USB Standard Rev. 1.1.

The colour LCD controller supports STN, DSTN, and TFT liquid crystal panels. The memory for storing display image data employs a UMA (Unified Memory Access) architecture and is shared with system memory. This makes it possible to display up to 65,536 colours with a 640 x 480-dot screen size. The LCD controller also includes a 2.4Kbyte line memory buffer, providing the capacity for high speed drawing of large volumes of data.

Support is available for operation of the device under Linux, as well as several other popular embedded operating systems.
