The USB83340 is optimized for use in applications where a low operating current and standby currents are essential. The device integrates 3.3 V and 1.8 V regulators, making it possible to operative the device from a single power supply.
The USB83340 uses Microchip's wrapper-less technology to implement the ULPI interface; allowing the PHY to achieve low-latency receiving and transmitting.
Applications
- In-vehicle USB Host implementations
- Infotainment test interface
- Automotive head unit
- Portable device charging via USB
- Rear seat infotainment access
- Internal connectivity bus
- Isolate high-value SoCs from outside
