USB Hub/Host Expands Embedded I/O August 2004 Issue Published Date: August 12, 2004
Tailored to embedded and industrial designers, the PCM-2004 is a USB 2.0 compliant host controller board with integrated hub that provides up to eight USB ports. There are three models in the line. A base model, for applications requiring just a USB hub, employs an SMSC USB20H04 hub controller that accommodates up to four peripherals. The DX version utilizes NEC's UPD 720101 and adds five high-speed USB ports through a PCI-104 interface. The PCM-2004-Ultra expands the total number of USB 2.0 ports to eight. Pin headers are on board to drive link and activity LEDs, and a four-pin, power-input header is available if the boards are not installed in a PC-104 socket. For compatibility concerns, all PCI arbitration signals are selectable via jumpers. Price for the four-port PCM-2004 is $55 each. AAEON ELECTRONICS INC., Hazlet, NJ. (732) 203-9300.
