USBF4100, a USB Firmware memory chip, is a companion to the USB SmartHub™ family of controllers. Full custom programming alternatives are available upon request with latest version of the binary firmware, which contains application firmware and default hub configuration settings. The USBF4100 assures proper functionality, providing for decreased development time and engineering resource, and overall faster time to market. <br /> <br /> The USB Firmware memory family features a four-wire, SPI-compatible interface that allows for a low pin-count package, which occupies less board space and ultimately lowers total system costs. It is manufactured with proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches.
