ISP1161BM - Full-speed Universal Serial Bus single-chip host and device controller

General Description

The ISP1161 is a single-chip Universal Serial Bus (USB) Host Controller (HC) and Device Controller (DC) which complies with Universal Serial Bus Specification Rev 1.1.

These two USB controllers, the HC and the DC, share the same microprocessor bus interface.

Key Features

  • s s s s s s Complies with Universal Serial Bus Specification Rev 1.1 Combines HC and DC in a single chip On-chip DC complies with most Device Class specifications Both HC and DC can be accessed by an external microprocessor via separate I/O port addresses Selectable one or two downstream ports for HC and one upstream port for DC High speed parallel interface to most of the generic microprocessors and Reduced Instruction Set Computer (RISC) processors (Hitachi SH-3 and SH-4, MIPS-based RISC, ARM7/9.

ISP1161 Full-speed Universal Serial Bus single-chip host and device controller Rev. 01 — 3 July 2001 Product data 1. General description The ISP1161 is a single-chip Universal Serial Bus (USB) Host Controller (HC) and Device Controller (DC) which complies with Universal Serial Bus Specification Rev 1.1. These two USB controllers, the HC and the DC, share the same microprocessor bus interface. They have the same data bus, but different I/O locations. They also have separate interrupt request output pins, separate DMA channels that include separate DMA request output pins and DMA acknowledge input pins. This makes it possible for a microprocessor to control both the USB HC and the USB DC at the same time.
