USB3320C-EZK-TR

1 PRODUCT FEATURES

•  Integrated ESD protection circuits

— Up to ±15kV IEC Air Discharge without external devices

•  Over-Voltage Protection circuit (OVP) protects the VBUS pin from continuous DC voltages up to 30V

•  Integrated USB Switch

— No degradation of Hi-Speed electrical characteristics

— Allows single USB port of connection by providing switching function for:

– Battery charging

– Stereo and mono/mic audio

– USB Full-Speed/Low-Speed data

•  flexPWR® Technology

— 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 (±10%)

•  Integrated battery to 3.3V regulator

— 2.2uF bypass capacitor

— 100mV dropout voltage

•  “Wrapper-less” design for optimal timing performance and design ease

— Low Latency Hi-Speed Receiver (43 Hi-Speed clocks Max) allows use of legacy UTMI Links with a ULPI bridge

•  Selectable Reference Clock Frequency

— Frequencies: 12, 13, 19.2, 24, 26, 27, 38.4, 52 or 60MHz - pin selectable

•  External Reference Clock operation available

— ULPI Input Clock Mode (60MHz sourced by Link)

— 0 to 3.6V input drive tolerant

— Able to accept “noisy” clock sources as reference to internal, low-jitter PLL

•  Internal Oscillator operation available

— This mode requires external Quartz Crystal or Ceramic Resonator 

•  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 Supplement Revision 2.0 specification

•  Supports Headset Audio Mode

•  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 Lead-free RoHS Compliant Package 

• (5 x 5 x 0.90 mm height)
