Original Press Release
Easy-To-Use USB-Powered 24-Line General Purpose I/O Module
Press release date: April 11, 2002
Fairport, New York. USBI/O24 is Gigatechnology's (Australia) low-cost integrated module for the input and output of digital signals from a computer system by connection to the USB port. Based on the FTDI FT8U245AM USB IC and the UBICOM SX48 microcontroller, USBI/O24 is capable of transfer rates of up to 250,000 x 8 bit port reads or writes per second. Each I/O pin is individually configurable as an input or output. Input pins are TTL level compatible and the output pin can each sink or source up to 30mA per pin.
The 24 I/O pins are independently programmable in 3 groups of 8 to form a single high-speed module which can be a building block for fast computer I/O needs. Based on FTDI FT8U245 High-Speed USB IC & UBICOM SX48, it is easy to connect to 0.1" pitch headers which fit standard IDC connectors. With an integrated Type-B USB connector onboard, the unit includes serial number EEPROM and FLASH microcontroller. Both USB Enumeration information and the microcontroller can be re-programmed to suit customer needs. Moreover, the module powered from USB bus (up to 450mA from USB for user application) so no external power supply is required.
Module Firmware & Software supplied includes a Virtual Comm Port driver which allows access as a regular serial port, or DLL drivers allow direct access by DLL calls. USBI/O24 is easy to program from popular languages C, Basic, Delphi, etc. with a simple command set for easy control of ports and data transfer
USBI/O24 is $69 from stock from Gigatechnology's North American agents, Saelig Co. Inc. For more details, contact Saelig Co. Inc (Fairport, NY) at 716-425-3753 or firstname.lastname@example.org.
