USB333x/334x USB Transceiver Family
Hi-Speed USB 2.0 Transceiver Family Featuring RapidCharge Anywhere
for Smartphones and Other Portable Devices
™
SMSC’s USB333x/334x family of Hi-Speed USB 2.0 transceivers delivers enhanced USB functionality for the portable market with
support for the latest USB-IF Battery Charging 1.1 (BC 1.1) specification. This family of devices dramatically reduces the time
required for battery charging and system bill-of-material (BOM) costs by up to 60% over competitive solutions. SMSC has positioned
itself as a leader in providing innovative solutions in support of BC 1.1. The new USB333x/334x provides an excellent compliment
to USB charging ports by enabling portable devices to negotiate up to three times the charging current compared to a standard USB
port, resulting in faster battery charging. The USB333x/334x is designed in a small footprint package and reduces the number
of external components through the integration of voltage regulators and other discretes. Additionally, SMSC’s complimentary and
confidential USBCheck™ online design review service is available for customers who select the USB333x/334x for their application
design-in*.
