SMSC announces industry’s first USB 2.0 hub for portable CE apps

HAUPPAUGE, USA: SMSC, a leading semiconductor company enabling content rich connectivity systems, announced its latest advance in Hi-Speed USB 2.0 connectivity, the USB3803 USB 2.0 Portable Hub. This industry-first Hi-Speed USB Portable Hub designed for portable devices offers a compelling USB connectivity solution for portable battery powered applications due to its low pin count and small size.

As portable devices continue to add more features and connectivity architecture becomes more complex, it is necessary to have more than one USB port to manage communications with internal and external peripheral devices. SMSC’s low-power USB3803 USB 2.0 hub controller offers three downstream ports and is specifically designed for portable embedded applications where more than one USB port is required.

The USB3803 can easily attach to an upstream port as a Full-Speed or Full/Hi-Speed USB hub and supports Low, Full and Hi-Speed (if operating as a Hi-Speed hub) downstream devices on all enabled downstream ports. The pin count has been reduced, making the device well-suited for portable, battery-powered embedded systems where power consumption, small package size, reduced BOM cost and Battery Charger (BC) detection capabilities are critical design requirements.

"The USB3803 is the industry's first USB 2.0 hub controller designed specifically for portable Consumer Electronics products such as smartphones, tablets and e-readers. Designed to deliver the low-power and ultra-small footprint that portable product designers demand, the USB3803 also delivers robust USB performance proven through multiple generations of SMSC USB 2.0 hub controller products," said Eric Kawamoto, Vice President & General Manager of Consumer Electronics Products at SMSC.

The USB3803 integrates the latest USB-IF Battery Charging 1.2 specification with SMSC’s RapidCharge Anywhere functionality that dramatically reduces the time required for battery charging, while flexible power regulators facilitate simple design into battery-powered devices.

Samples of the USB3803 are available now.
