General description

The ISP1160 is an embedded Universal Serial Bus (USB) Host Controller (HC) that complies with Universal Serial Bus Specification Rev. 2.0, supporting data transfer at full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s). The ISP1160 provides two downstream ports. Each downstream port has an overcurrent (OC) detection input pin and power supply switching control output pin. The downstream ports for the HC can be connected with any USB compliant USB devices and USB hubs that have USB upstream ports.

The ISP1160 is well suited for embedded systems and portable devices that require a USB host. The ISP1160 brings high flexibility to the systems that have it built-in. For example, a system that has the ISP1160 built-in allows it to be connected to a device that has a USB upstream port, such as a USB printer, USB camera, USB keyboard, USB mouse, among others.

Features

■ Complies with Universal Serial Bus Specification Rev. 2.0

■ Supports data transfer at full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s)

■ Adapted from Open Host Controller Interface Specification for USB Release 1.0a

■ Selectable one or two downstream ports for HC

■ High-speed parallel interface to most of the generic microprocessors and Reduced Instruction Set Computer (RISC) processors such as:

◆ Hitachi? SuperH? SH-3 and SH-4

◆ MIPS-based? RISC

◆ ARM7?, ARM9?, and StrongARM?

■ Maximum 15 Mbyte/s data transfer rate between the microprocessor and the HC

■ Supports single-cycle and burst mode DMA operations

■ Built-in FIFO buffer RAM for the HC (4 kbytes)

■ Endpoints with double buffering to increase throughput and ease real-time data transfer for isochronous (ISO) transactions

■ 6 MHz crystal oscillator with integrated PLL for low EMI

■ Built-in software selectable internal 15 k? pull-down resistors for HC downstream ports
