ISP1181A

Full-speed Universal Serial Bus peripheral controller

Rev. 05 — 08 December 2004

Product data

1.

General description

The ISP1181A is a Universal Serial Bus (USB) peripheral controller that complies

with

Universal Serial Bus Speciﬁcation Rev. 2.0, supporting data transfer at full-speed

(12 Mbit/s). It provides full-speed USB communication capacity to microcontroller or

microprocessor-based systems. The ISP1181A communicates with the system’s

microcontroller or microprocessor through a high-speed general-purpose parallel

interface.

The ISP1181A supports fully autonomous, multi-conﬁgurable Direct Memory Access

(DMA) operation.

The modular approach to implementing a USB peripheral controller allows the

designer to select the optimum system microcontroller from the wide variety available.

The ability to reuse existing architecture and ﬁrmware investments shortens

development time, eliminates risks and reduces costs. The result is fast and efﬁcient

development of the most cost-effective USB peripheral solution.

The ISP1181A is ideally suited for application in many personal computer peripherals

such as printers, communication devices, scanners, external mass storage (Zip®

drive) devices and digital still cameras. It offers an immediate cost reduction for

applications that currently use SCSI implementations.
