support
• flexPWR^® Technology
- Extremely low current design ideal for battery
powered applications
- “Sleep” mode tri-states all ULPI pins and
places the part in a low current state
- 1.8V to 3.3V IO Voltage
• Single Power Supply Operation
- Integrated 1.8V regulator
- Integrated 3.3V regulator
- 100mV dropout voltage
• PHYBoost
- Programmable USB transceiver drive
strength for recovering signal integrity
• VariSense^TM
- Programmable USB receiver sensitivity
• “Wrapper-less” design for optimal timing perfor-
mance and design ease
- Low Latency Hi-Speed Receiver (43 Hi-
Speed clocks Max) allows use of legacy
UTMI Links with a ULPI bridge
• External Reference Clock operation available
- 19.2MHz Reference Clock needed
- ULPI Clock Input Mode (60MHz sourced by
Link)
- 0 to 3.6V input drive tolerant
- Able to accept “noisy” clock sources as refer-
ence to internal, low-jitter PLL
- Crystal support available
• Smart detection circuits allow identification of
USB charger, headset, or data cable insertion
• Includes full support for the optional On-The-Go
(OTG) protocol detailed in the On-The-Go Sup-
plement Revision 2.0 specification
• Supports the OTG Host Negotiation Protocol
(HNP) and Session Request Protocol (SRP)
• UART mode for non-USB serial data transfers
• Internal 5V cable short-circuit protection of ID, DP
and DM lines to VBUS or ground
• Industrial Operating Temperature -40°C to +85°C
• 32 pin, QFN RoHS Compliant package
(5 x 5x 0.90 mm height)
Applications
The USB3370 is the solution of choice for any applica-
tion where a Hi-Speed USB connection is desired and
when board space, power, and interface pins must be
minimized.
