Interfacing ISP1181 to Hitachi SH7709 RISC processor

Posted: 30 Jun 2010     Print Version  Bookmark and Share

Keywords:USB interface  RISC processor  interfacing processors 

The ISP1181 is a USB interface device that complies with Universal Serial Bus Specification Rev 1.1. It provides full-speed USB communication capability to microcontroller- or microprocessor-based systems. The ISP1181 communicates with the system microcontroller or microprocessor through a high-speed general-purpose parallel interface. It also supports fully autonomous DMA operation.

Because of its high performance and versatile interface configurations, the ISP1181 is ideally suited for applications in many PC peripherals such as printers, scanners, external mass storage devices, digital still cameras, PDAs and communication devices. This means it can be connected to the external bus interface of any microcontrollers or RISC processors. This application note will address the most important issues in such a design, using the Hitachi SH7709 RISC processor as an example.
