　　Cypress Semiconductor Corporation’s MoBL-USB™ FX2LP18 (CY7C68053) is a low voltage (1.8 V) version of the EZ-USB® FX2LP (CY7C68013A), which is a highly integrated, low power USB 2.0 microcontroller. By integrating the USB 2.0 transceiver, serial interface engine (SIE), enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip, Cypress has created a very cost effective solution that provides superior time-to-market advantages with low power to enable bus powered applications.

　　The ingenious architecture of MoBL-USB FX2LP18 results in data transfer rates of over 53 Mbytes per second, the maximum allowable USB 2.0 bandwidth, while still using a low cost 8051 microcontroller in a package as small as a 56VFBGA (5 mm x 5 mm). Because it incorporates the USB 2.0 transceiver, the MoBL-USB FX2LP18 is more economical, providing a smaller footprint solution than USB 2.0 SIE or external transceiver implementations. With MoBL-USB FX2LP18, the Cypress Smart SIE handles most of the USB 1.1 and 2.0 protocol in hardware, freeing the embedded microcontroller for application-specific functions and decreasing development time to ensure USB compatibility.

　　The General Programmable Interface (GPIF) and Master/Slave Endpoint FIFO (8 or 16-bit data bus) provide an easy and glueless interface to popular interfaces such as ATA, UTOPIA, EPP, PCMCIA, and most DSP/processors.
