STUSB02EQR屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的STUSB02EQR驅(qū)動(dòng)器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過(guò)延長(zhǎng)電纜或印制線進(jìn)行通信。確切的功能會(huì)因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類(lèi)的功能，這些功能對(duì)于通信用途可能并非絕對(duì)必要，但對(duì)于可能的使用環(huán)境卻是明智之選。

Description

The STUSB02E is a single chip USB transceiver that supports both full-speed (12Mbps) and low speed (1.5Mbps) operation. 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.

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

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.
