The Managed-Memory NFX Token is a portable data transport device optimized for use in OEM systems controlled by embedded microprocessors. The NFX implements several features and benefits needed by embedded engineers and not offered in consumer-based electronic devices. The token (128 MByte-1GByte) is used to transport data to and from non-networked electronics that are deployed in any environment. It provides both an SPI interface for simple direct connection to microprocessors and a USB electrical interface to facilitate connection to PCs. The NFX Managed-Memory token (patent pending) is designed specifically to solve the short-comings of using consumer memory devices in embedded OEM systems. Essentially, it takes care of virtually all of the additional tasks that an embedded engineer would have to do if they were to design-in a “camera-card” type of consumer device.
