Surface mount unit can automatically switch between 1.5 Mbps and 12 Mbps, as application requires. Used with host controller, single module counts as 2 USB hubs for cascaded applications, while providing immunity to EMI. Safety isolation barrier meets requirements of 250 Vac systems in IT and medical environments.
Original Press Release:
Murata's Cost Effective Powered Data Isolator Module Provides Data and Power Isolation in Critical USB Environments
Hoofddorp, Netherlands – Murata has introduced the NMUSB202MC, an extremely competitively priced surface mount powered data isolator module that conveniently provides dual port USB data and power isolation from a single upstream port with full power (500mA) available from each port. Used with a host controller a single module counts as two USB hubs for cascaded applications with the level of safety isolation additionally providing effective breaking of ground loops and immunity to EMI in harsh environments.
The module is aimed at industrial control applications where USB is becoming increasingly common for communications with sensors. It is also ideal for use in medical environments with the increasing use of USB for low cost sensing and communication where isolation is necessary for safety and noise immunity.
‘Full’ USB speed operation (12Mbps) is supported, limited by the data isolation chipset. The module is also able to switch automatically between low (1.5Mbps) and full speed operation, as the application requires.
The module’s full compliance with USB 2.0 specification enables hassle free, full ‘plug and play’ operation and its surface mount package for placement on the host motherboard enables the USB isolation function with a single SMT component.
Full power, 5V/0.5A, meeting the USB bus standard is available from each downstream port and users may power any USB compatible device from the NMUSB module. The ports are short circuit and overload protected. The source power of 5V can be provided by an external adapter or system voltage rail.
The NMUSB202MC’s reinforced safety isolation barrier meets the requirements of 250VAC systems in IT and medical environments for operator protection, so users may confidently use the product to provide safety isolation in USB connections in critical applications. Safety agency recognition is pending. A full industrial temperature range of -40 to +85 degrees C is accommodated.
Manufactured in Murata’s own factory using the company’s own techniques and processes, the module is extremely competitively priced, in some instances being significantly less expensive than competitors’ products. USB communication is extremely low cost with many compatible products available. To take advantage of this in harsh environments, users can utilize the function of isolation achieved with Murata’s NMUSB202MC DC-DC module.
