Cypresss EZ-USB® FX2LP™ (CY7C68013A/14A) is alow-power version of the EZ-USB FX2™(CY7C68013), which isa 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 cost-effective solution that provides superior time-to-market advantages with low power to enable bus-powered applications. The ingenious architecture of FX2LP results in data transfer rates of over 53 Mbytes per second (the maximum allowable USB 2.0 bandwidth), while still using a low-cost 8051microcontroller in a package as small as a 56 VFBGA (5 mm ´5 mm). Because it incorporates the USB 2.0 transceiver, theFX2LP is more economical, providing a smaller-footprint solution than a USB 2.0 SIE or external transceiver implementations. With EZ-USB FX2LP, the Cypress Smart SIE handles most ofthe USB 1.1 and 2.0 protocol in hardware, freeing the embedded microcontroller for application-specific functions and decreasing the development time to ensure USB compatibility. The general programmable interface (GPIF) and Master/Slave Endpoint FIFO (8-bit or 16-bit data bus) provide an easy and glue less interface to popular interfaces such asATA, UTOPIA,EPP, PCMCIA, and most DSP/processors. The FX2LP draws less current than the FX2 (CY7C68013), has double the on-chip code/data RAM, and is fit, form, and function compatible with the 56-, 100-, and 128-pin FX2.Five packages are defined for the family: 56-ball VFBGA, 56-pin SSOP, 56-pin QFN, 100-pin TQFP, and 128-pin TQFP.
