GENERAL DESCRIPTION
The FT8U232AM is a cost-effective single chip USB UART ( U-UART ) solution for transferring serial data
over USB. With data transfer rates of up to 920k baud ( RS232 ) and 2,000 k baud ( RS422 / RS485 ) , the
FT8U232AM significantly raises the performance level above that above that of traditional ISA and PCI based
UART solutions whilst offering true plug and play and easy interfacing through it’s USB interface.
Its flexible architecture allows this IC to be used in many different application areas - USB modems,
Legacy RS232
Ù USB Converter cables, USB interface cables for PDA’s , Bar Code Scanners , RS422 data links
and instrumentation – in fact almost any equipment that previously used a slow RS232 link for communication.
Virtual COM port drivers are available for the FT8U232AM for Windows ’98, Windows 98 SE and Windows
2000. Drivers for other operating systems are currently under development.
