MIC2550中文资料Universal Serial Bus Transceiver数据手册Microchip规格书

描述 Description

**NOT RECOMMENDED FOR NEW DESIGNS***The MIC2550 is a single-chip transceiver that complies with the physical layer specifications for Universal Serial Bus (USB).The MIC2550 supports full-speed (12Mbps) dual supply voltage operation (patent pending) and low-speed (1.5Mbps) operation.A unique dual supply voltage operation allows the MIC2550 to reference the system I/F I/O signals to a supply voltage down to 2.5V while independently powered by the USB VBUS.This allows the system interface to operate at its core voltage without addition of buffering logic and also reduce system operating current.

特性 Features

• Compliant to USB Specification Revision 2.0 for low-speed (1.5Mbps) and full-speed (12Mbps) operation
• Compliant to IEC-61000-4.2 (Level 2)
• Operation down to 2.5V
• Dual supply voltage operation
• Integrated speed-select termination supply
• Very low power consumption meets USB suspend-current requirements
• Small 14-pin TSSOP packages

简介

MIC2550属于集成电路（IC）的驱动器接收器收发器。由制造生产的MIC2550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。
