STUSB03E中文资料USB收发器数据手册ST规格书

描述 Description

The STUSB03E is a single chip transceiver that complies with the physical layer specifications of the Universal Serial Bus (USB) v2.0 standard. It has an integrated 5V to 3.3V regulator which allows direct powering from the VBUS. The transceiver has an integrated voltage detector to detect the presence of the VBUS voltage and features an internal D+ pull-up resistor implemented in accordance with the 27% resistor ECN.

The STUSB03E also supports Sharing mode when VBUS is not present, which allows the D+/D– lines to be shared with other serial protocols.

It supports both full-speed (12Mbps) and lowspeed (1.5Mbps) operation. It is also designed to operate down to 1.6V so that it is compatible with lower system voltages of most portable systems, which include PDAs, MP3 Player and Cell phones.

特性 Features

• Integrated D+ pull-up resistor for FS operation
• Software controlled re-enumeration
• Small QFN16 lead free package 3x3 mm2
• Very low power consumption to meet USB ‘suspend’ current requirements
• Compliant to USB V2.0 for full-speed (12Mb/s) and low-speed (1.5Mbps) operation
• ESD Compliant to IEC-61000-4.2 (level 3) on D+, D- lines
• HBM = ±14kV on D+, D– lines; ±5kV on VBUS
• Integrated 3.3V output LDO
• No power supply sequencing requirements
• Separate I/O supply with operation down to 1.6V

简介

STUSB03E属于集成电路（IC）的驱动器接收器收发器。由ST制造生产的STUSB03E驱动器，接收器，收发器该系列产品的主要功能是提供必需的硬件资源，以通过延长电缆或印制线进行通信。确切的功能会因所采用的通信协议而异，可能包括诸如瞬态抑制之类的功能，这些功能对于通信用途可能并非绝对必要，但对于可能的使用环境却是明智之选。
