USB3320
USB3320 is Highly Integrated Full Featured Hi-Speed USB 2.0 ULPI Transceiver manufactured by Microchip Technology.
Features
- Integrated ESD protection circuits
- Up to ±15k V 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
- flex PWR® 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
- 2.2u F bypass capacitor
- 100m V 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 Ro HS pliant Package
(5 x 5 x 0.90 mm height)
