V.90 USB Modem
Introduction
1 -Introduction
The goal of this manual is to provide general information for the developers on evaluation of the ST USB
Modem. The USB provide a 12Mbps high bandwidth for virtually unlimited data throughput instead of the
legacy 16550 UART bottleneck with the traditional modems.
ST USB Modem is a very flexible modem that has one of the smallest real estate and power consumption out
on the market. Because of the simplicity of the modem design, the time to market is quick and less overhead.
With this modem, all future driver releases will be a simple software update.
This product has been developed in cooperation with Smart Link Ltd, who ported “USB-Modio”, its host
based modem and system software into ST system and hardware platform.
ST USB modem provides an easy installation and a strong performance that reduces the Total Cost of
Ownership.
