STUSB03E is a USB transceiver produced by ST company. It supports USB 2.0 protocol with a speed of up to 12Mbps. It supports low power consumption and low voltage power supply, and is suitable for PDAs, MP3 players and mobile phones.
The STUSB03E is a single-chip transceiver compliant with the physical layer specifications of the Universal Serial Bus (USB) v2.0 standard. It supports both full-speed (12Mbps) and low-speed (1.5Mbps) operation and features an integrated 5V to 3.3V regulator allowing direct powering from VBUS. The device is designed to operate down to 1.6V, making it compatible with lower system voltages found in portable systems like PDAs and cell phones.
| USB Speed | Full-speed (12Mb/s) and low-speed (1.5Mbps) |
|---|---|
| Supply Voltage (VBUS) | 4V to 5.5V |
| System Interface Supply Voltage (VIF) | 1.6V to 3.6V |
| Operating Temperature Range | -40 to + 85 °C |
| Storage Temperature Range | -65 to + 150 °C |
| Package | QFN16 (3mm x 3mm) |
The system interface supply voltage (VIF) operates between 1.6V and 3.6V.
Yes, it supports Sharing mode when VBUS is not present, allowing D+/D- lines to be shared with other serial protocols.
The internal pull-up resistor is implemented in accordance with the 27k resistor ECN.
